Working on both Mercedes S Classes + A Snake in my Oven Featuring Austin! 

someone said mismatched tires...def trip wheel speed sensor

I wish i had a friend as loyal as Austin

Might have something to do with Miss matched tires.

You need all wheels and tyres to match and be the same sizes so the rolling radius is equal, even worn tyres mixed with new tyres will fudge it. That's why the implausible signals and abs errors are pinging up.. Hope that helps..

Battery could be low voltage and 4 matic is super sensitive to miss matched Tires

The compressor probably isn't making enough pressure. My airmatic compressor failed shortly after replacing struts. If the pump is failing, and takes to long to build pressure, you'll get an error message too.

I just bought my first copart rebuild because of you. A 2015 Mercedes GLK350 with 20k mileage. The subframe was trashed, oil pan busted, power steering(electric) trashed. No blown bags. No blown seatbelts. The frame rails are straight. I'm going to have 13k into a car worth 14k, But had fun with the rebuild. Tesla killed the resale on Mercedes. I have had fun ordering parts and spending time under a car on jack stands mulling over the meaning of life. I recommend a Covid rebuild for anyone bored with this pandemic... Oh yeah, we needed a new family car, my 2001 BMW X5 is getting passed down to my son, he will kill it in the next few years for sure. I usually drive my cars to the salvage yard at end of life. The GLK350 has about 25 years left in it. I'm happy with my investment. It is more valuable than 13k to me. It feels new...I'll be 70 when the GLK350 will need replacement...... WTF!!! Life moves too fast!!

Airmatic? more like problematic!

Randy... you can do it, and I want to see this car going back to the road. You can do it.

Hi Randy, the airmatic is caused by the mismatched tires. It can interfere with the abs system as well.

Floating grounds will do this kind of stuff with computer equipment and your working on basically a computerized car,what I mean by a floating ground is you will experience voltage on ground of the car. It should be 0 volts on ground , the electronic circuits run on any wear from -5volts to + 5 volts and 12 volts so if your grounds have any kind of voltage on them it will it will screw up the signal voltage to the computers .

Randy back away for a few days and go back to it. some sugestions on conments, I wish you luck and blessings, Keep Kicking.

Great content Randy! I think you're real close on the Benz. Get the tires matched and I bet half the crap goes away.

Sorry Randy I know the feeling! Do this remove the new computer u just installed and install the old one! See if the codes you didn't have before goes away!!!

ABS sensors, mismatch tires and alignment issues can deploy the error codes.

I know your feeling. I bought a ml55 2001 amg and I had to put a used engine in it but it was worth every penny! Oh I also had to re do my transmission. But it was worth it cause it runs great now.

when you have different wheel/tire size you will be have different speeds on wheels sensors. For computer is problem...

Well I enjoyed it Randy thanks for the extra content good luck my friend and all you do live long and prosper🖖

You and Austin make a great team and also great content. Keep him in your videos 👍

only Alex from LegitStreetCars can help you mate, it wont be cheap; but you need someone with good experience with 'ol mercs

Hang in there Randy, I think the old computer needs to go back in. Once fixed this S class needs a cut and polish, then install the facelift lights on it. Good opportunity to do a collab with Car Wizard!

I'd take a break from the car and get that damn snake out of the stove. Thanks for the video.

Excellent work and thanks for the content Edited stay safe

Hello from Switzerland, Regarding some issues regarding related to implausible speed of the gearbox (and going to limp mode), check your electronics modules along the ECU. I had a similar issue with my w211 and 5 days of debugging, including conductor plate change did nothing. I checked the modules themselves. Found the Esp module with 2 pins slightly corroded, checked it by being sure the connector was making proper connections and it make the errors intermittent. Basically, the module was going bad. Changed it and a pleasure to drive since. More simply, check every module that make faults. If pins are corroded, change it. If connector is in discutable shape, make it bright again and some conductor spray.

Sounds like your battery is going bad, those Mercs go nuts when they start to get low voltage

You really love hearing your voice nowadays

I feel your frustration. Made a pretty good living in a shop for quite a while. I had those “cars” too. It’s good that you know when to say enough. Austin Carr.....cool guy! Really looking forward to his work. Subbed to him as well. Stay safe and have a good one.

Your channel is really interesting. And you are good at explaining what you are doing on those cars. Keep it up!

Randy, I had a few Mercs before, the transmissions normally does start acting up after some time. Normally the valves in the gearbox gets stuck to the valve body which does cause it to get stuck in a gear. After I serviced it myself and took it on a shakedown run driving it real hard hitting the rev limiter in every gear and warming everything up, the codes clear up and the car shifts properly again. Its a crazy thing owning a Merc but it is a very fun experience.

I enjoy watching your house videos

Randy, it really helps to know how the systems in the car work together when troubleshooting an issue. Having owned several of the W220 cars like this one, often a single sensor, broken wire, terminal, etc will throw a host of codes. I invested in a STAR system and it has helped me solve many issues with my vehicles. Look for the common connection between the codes and not so much the codes themselves. Also, get the tire and rim sizes matched or you will have codes thrown. TCM also needs to be coded to the vehicle if you have not done so; else it will be in limp mode.

Bro I give you all respect for fight for this car keep pushing god bless

Don't give up, review everything, it will be a fantastic car when its done!

You are making great progress and I am learning a lot Thanks!

I was getting the same airmatic visit workshop error, the suspension were fine but i could not switch gears. Changed the conductor plate with new oil and filter. It worked no more error.

Randy don’t give up you always get it sorted in the end 👍🏻. Take a break from the S500 and work on another car. You will get it sorted out just need to be in the right head space 👍🏻👍🏻😁😁. So glad I found this channel always keeps me entertained and I love what you guys get up to over there in the USA 🇺🇸 😊😊

Randy, we're too far in to stop now... Famous WWII reference, when asked to surrender by the Germans, the American commander sent a one word reply.... NUTS!

Randy ,You can patch the line with a steel tube and 2 hose clamps ! Easy fix !!! Dude Take care

Great quality content Randy. Love the format and the new truck is ace!

Oh! Check the ground strap. Clean the contact points and tighten. Maybe add an auxiliary ground strap.

on my vag witch is similar, mismatch tires would throw up errors with wheel speed. this could also be messing with the height adjustment. get the tires sorted then clear codes and try again

A local Hydraulic line shop should be able to repair your Mercedes power steering line.

Dear Randy, don´t give up is great content!!!, just install the new set of tires and all the abs ligts and so on will go out, the speed sensors got crazy because they got diferent lectures on each wheel. You should contact Mercedessource I´m shure he can Help you out with the Airmatic. Also you should turn of the Active Damping System (ADS) thats the button with the 2 red Dots, I beliewe the new ones you bought came with out this feature. Keep the good work!!!

I have one of those ryobi surface cleaners as well....those are great!

That’s a easy fix I own / owned a few s500 n have done all the work myself they really easy cars to work on

I would focus on the ABS wiring and sensors if you wanted to go forward with the white car, ABS/ESP/ASR/BAS faults will result in associated modules incurring faults such as the ETC/EGS(Transmission Control Module), AirMatic, PCM, and Front SAM. The ETC faults must be cleared to bring the transmission out of limp mode as well. If you dont assess the ABS wheel speed sensors and connectors/wiring at all four corners, then you will continue to be frustrated by all the faults resulting from the ABS wheel speed sensors being pontentially faulty or damaged due to flood water or having corrosion at the connectors or wiring. I would look at wheel speed signals as well to narrow down the culprit of the ABS issues. You're doing great, keep it up Randy!

Don’t stop, keep going at it. I have a great time watching you figure it out. Just for content. Keep buying and selling other cars. But keep the Benz for entertainment .. don’t give up, is fun watching you get frustrated . lol

Great job on the fence! Nope to your animal problems, No a thank you. Hopefully, when you build the shop Randy you can re pour the cement on the driveway too. Austin is a great friend.

Thanks for the interesting channel. I think that you should order the parts for the gearbox on the S500. While you wait for those you should fix the S430, enjoy it on a road trip perhaps. When you are satisfied with the S430 you should take a deep breath and dive in to the S500 again, fix the gearbox computer and put on matching tires, perhaps borrowed from the S430. If that doesn't fix the car it is time to cut your losses. The W setting for the gearbox on a Mercedes is for Winter, it doesn't let you use 1:st gear and probably makes gear shifts smoother and at lower rpm, all in order to ensure grip on icy roads. Even the rear wheel drive Mercedes is fun to drive on snow and ice since the ASR (Anti Slip Regulation) lets you drift nicely while placing you in the direction you want to go.

wowww, how it get there that snake, i cant believe it, thank you for share

you can try a few things. 1: 4 the same size rims and tires 2: check all fuses every time 3: Start the car, then with your steering wheel all the way to the left, then all the way to the right, then your abs and your airmatic message will go away. 4: battery check 5: disconnect battery for 30 minutes

Hey you the man, keep the CAR faith.

I agree... time to "drop back 10 and punt" that MB down the road...

It'd be interesting to see what it actually takes to get all the lights off on the s500, with a rundown at the end.

House looks 90% less ghetto without the chainlink fence, I like it. And I just bought a Karcher surface cleaner to do the same to my driveway, tired of waving the wand back and forth forever, didn't realize Ryobi made one too, but show us the end result! Probably best to put some sealer on the concrete, it'll make any spills easier to clean up.

Like what scotty says "they're endless money pitts"!!😂😂🤣👍🏼

What about searching all conectors for modules inside kick panels and also sandpaper the battery terminals?

Hello. Do know that the speedometer might be using the same signal that the ABS uses??? Maybe a ABS-sensor is broken.

Do you know any good body shop that takes care of small rust issue and paint in or near OKC?

Randy I agree with you on that one.

Check all 4 tires, make sure they are same size. Could be a good starting point?

To reset abs you have to turn the key to on pos then rotate steering wheel all the way left then right and light should go out

Have you checked the trans sensor and or solenoid? And make sure all connections are clean and dont have trash in it. the will make the car mess up like its doing. I love watching you if anyone can figure it out I know you can keep up the good work.

Hi Randy. All the fault codes are from the same cause, the ABS control module. The ABS receive the speed signal from each wheel and uses the CAN Bus to share that information with the engine control module, the transmission control module, the dash, and so on. The TCM need the speed information for shifting, and the ECM needs that information for the fuel injection cut off in desacceleration. Maybe, as many people said, the mismatch tyres are confussing the ABS module, because for the ABS Module, each wheel has a different speed. Put the S430 wheels in the S500, clear the codes and go for a test drive. If the fault continues, maybe the replacement ABS module is bad or you have a problem with the wiring. Best wishes from Uruguay.

I love the 05 S430 4MATIC

You have still got the awd Mercedes going for you. Hope everything works out.

Wouldn't the 5th outlet one be like a return line, in some fashion on the pump block?

focus should be on getting an expandable metal building at AAR HQ. You have a great truck and trailer, don't trade those away. Forget about getting a replacement for the Corvette, once the litigation is sorted out. If you want a personal car, keep one of the cars you're fixing, like the S430. I personally would like to see what the long-term issues are in having an S430, or a Marauder. Suggest moving the S500 to Weird Beard, if he'll accept the car. He does a great job on picking up where you leave off. All the very best wishes, Rand.

Good Afternoon My Good Friend Randy Of Auto Auctions Rebuilds & God Bless You & All Of You're Whole Family This Afternoon From You're Good Friend Timbo White

Next project, pulling out that dead tree on the left of your property! lol

the fifth port on the air manifold is likely to vent down excess pressure from any of the 4 corners.

The tires dont matsch in height when you drive then the ABS goes in falt modus

double check the ride height sensors at each corner of the car, especially the right side.. might have some luck with them. Theyre slightly tucked in the corner of each wheel well.

I think you should install the four new tires to insure the system take a level measurement correct from fixed datum

Randy You need to do good choices for you and your business. You helped me come to terms with a choice that I had made back in 2016 when I got rid of a 2002 Grand Cherokee Overland that I LOVED........It was Daimler Chrysler with 274,000 miles on it with an all original drive train..........I still miss it but You have helped me move on Thank You!!!!!!!!

Hi, do you work on flooded cars like ACURA RLX?

You should build a tornado shelter under the driveway, and use it as a mancave... put another layer of concrete on it!

Another reason to start sticking with just a couple of brands. There are a ton of F150s out there, you have owned several. Repairing and reviving a Co-Part F150 would make great content that many would relate to. Could even have a few part outs to help supply parts for your builds.

The ecu module is not the same for the car. Keep the control module of the car that it had before. Clean it well. Did the ABS came off after cleaning it?

My back hurts watching you pull that fence!!!

for the 420 I think you need to replace the engine mount coz its damaging the hi pursuer hose

Give it a good wash and wax, clean the headlights and put it back to auction?

May be a dumb suggestion but can’t u use flex seal on the power steering hose

Schöner GTI in der Nachbar auffahrt👍

The 5th one goes to the airtank, it's around the same Area as the compressor, but on The opposite side (driver side)

Fences don't belong in the front yard Randy.......tear it down, up, out! Hahaha

Do you pay Austin for the work he does

I brought my shocks from amazon brand new rides pretty good

Have you tried switching the level sensors around from one side to the other side of the problem moves? Also as stated by others the different size tires maybe a big part of the problem

If u part it out i'll buy the wood trim and the steering wheel mine is identical runs great always says airmatic workshop but levels great.

What if the different tire sizes is cause the speed problem? Just a thought.

Typical flood car electrical nightmares not a Mercedes problem . It will never end .

. Hy! At my Mercedes-Benz w211 airmatic, on the front each wheel have an independet level sensor wich you can adapt by yourself with a screwdriver. On the back there is only one sensor for both wheels. i am not sure how it is on w220 chacy.

You saw MWM's vid... have you tested the voltage at the battery and the regulator on the alternator?

Have you checked battery voltage/battery terminals corrosion if the cars not getting correct voltage it may make sensors etc not work correctly

I know how you feel my linclon is the same way too when i fix one thing there is another problem but i still keep her

Isn't the broken power stearing line a recall issue?

That hose is what Flex Tape is for. LOL

The white Benz might be having issues because the tires. My 2011 Crown vic LX did not like having different tire sizes. The abs and Trac light comes on with a spare
