Mercedes ML350 ABS and ESP lights on, plus a come back... Fault finding and repair. 

Visual checks win once again with that short

You talk too much

The fan running all the time is your AC sensor right beside the radiator. Those multiple lights are multiple solutions: Blue riley Motor of module ( bypas #30 relay) Front of the module Wiring of the module. Under voltage is your voltage regulator on the alternator. Nothing is impossible is just a process of elimination.

Hi Luis, your thoroughness to detail, honest assessment, process elimination, and resolution makes watching your videos so enjoyable. Thanks

5001 fault on mercedes w204 what its supposed to be as a default???

Hello. Thanks for sharing. I have a 2011 R350. It came up with a code 5124.I replaced the affected sensor. But ABS light appears after driving few meters. If I turn off the engine, and restart it again the light will go off and driving few meters again, the light will come on. I have checked with my Launch scanner, the four speed sensors read about the same value when the car in in motion. I have tried to clean the area where the sensor sits, but the abs ESP-inoperative warning light keeps coming on. The wheel bearing looks good. Pls what else can I check. Thanks

Came for the ABS problem. Took soooooo soooooo long to actually get to that part of the video. Jeez.

How to reset the abs switch on my mb 350 ml

Luis, take the protective cover away from your ohm meter ! It looks awfull and is hard to read. :-)

I'm getting a 2002 w163 ml 320 i love it , great video 👍

Hi mate. Could you say pmease where is fuse for mlw164?

its better to be lucky than good but lucky and good call luis

I went to the dealer to get a diagnostic. They told me to replace all four sensors. I don’t think the four sensors will go out all at the same time that’s pretty rare. What are your thoughts?

It's great when you get lucky with a wiring fault like that Luis 😁😁

22 km/hr. Not miles. Just saying...

You’re triggering my OCD….. can you please remove what’s left of the shipping screen protector,from the voltmeter 😇🙈

More tube for mercidix cars thanks you

Great video thanks. 2013 ML350 Bluetec (w166 diesel) here. (270 000 km or 168 000 miles) Two weeks ago, I hit a bump on the road and the transmission jerked and then cruise control went offline. The dash lit up like a Chrismas tree (ABS, ESP, red parking brake icon, and another light that I can't remember). Had a check engine light and scanned. Got a code for the rear right wheel abs speed sensor (just like you). Ordered a new sensor from Rockauto (not OEM from Mercedes) and changed it myself. Cleared the code and all good for 2 weeks. Today, I had to drive for 4 hours. After about 3 hours, I hit a rough patch of road and my dash lit up like a Christmas tree again (same lights as before) and lost cruise control, blind spot sensors, I had multiple messages in the dashboard pop up. No check engine lights though... very strange. The jerking is weird, as if the transmission was slipping. Is it possible it's the wheel abs speed sensor acting up again because it's an aftermarket? One other thing, both my main batteries and my AUX batteries are original (10 years old). Is it possible that the batteries are causing low voltage issues?

If you know how much i love you bro I love more than your wife

You better get a lotteryticket finding that short! 😂

With that make sensor is rubbish but if you get a crankshaft sensor for a Ford transit in that make they buy them from Ford and grind the name off and reboxs them I won't put that make in a customer car it not worth the trouble

Is there something problem you couldn't fix it? Axxaxaxaxa you are the best!!!

Luis, I had a similar problem with the ESP/ABS on my own W204. I scanned the car and the error codes painted towrads the rear right ABS sensor. In live data the sensor was still reading the correct speed. I changed the sensor but it didn't fix the problem. I changed the pickup ring because it had delaminated and it fixed it. I ended up reinstating the original sensor becase there was nothing wrong with it.

Thanks that was very helpful info about ABS I am going out to buy those sensor’s tomorrow

Wow Luis, seems like lady luck has come your way. It still, however, takes an eye for detail to spot that short, good job!

I thought you’d said no more after market electrical parts. Ha .
