HOW TO CHANGE MERCEDES CAM MAGNETS M271 ENGINE 

Great point!

Good tip!

You must have missed the bit where I used the special pigtail leads to stop oil ingress into the loom.

Oops friend! how did you do it I'm from Brazil and I have this leak problem only in the connector could you help me???

Hi there. You need to remove the magnet (3 screws), clean out any oil, and seal the gap between the magnet housing and the electrical plug with heat proof epoxy. The epoxy will stop the engine oil getting to the electrical connector. Good luck!

@@stevejones1318 thanks

@@stevejones1318 Thank you friend! Problem solved thanks to you! Now I have another one.... I realized that my car was weak after I moved it, that is, I fixed the sensors, do you know what it could be????

Have fun!

Thank you kindly!!

Thanks Ray, hope you are keeping well.

Cheers Fred. Eliminate the problem.

They are part of the variable valve timing system.

Cheers mate. Glad you enjoyed it.

The main sign will be the magnets leaking oil on the front of the motor. The Cam Position Sensors are a separate affair. There is one for each camshaft, The exhaust one is on the (looking at engine from the front of the car) left side towards the front of the car. The Exhaust one is on the right side under the engine top cover about two thirds of the way towards the rear of the car on the rocker cover. Both are held in by s single torx bolt and you can change them yourself in 5 minutes.

If youd like me to make you a quick video to show you where they are, let me know

Hi would really appreciate if you can make a video as it would help enormously especially in this lock down I can change them. Thanks again

just wait till they have the two of them. Doesn't make sense to do them separate

@@GeorgeEI7KO why the plastisk go side to side wihtout leaking On mine 😀

I'd imagine any generic o ring would do the job. The trouble is they leak out through the connector socket. This is the bigger issue.

Sorry, i am not familiar with this issue. The only thing i can think is perhaps the servo controlled flap in the black pipe between the supercharger and the intake could be at fault

Thank you for replying, okay sir I will check,tnx

Probably have to use electric contract spray. It won't penetrate whole loom but it'll clean it at least a bit

No, not necessary.

I'd change both if you could.

Thanks!

2047-001,2029-001 and 201C-001 I have those codes and CEL comes up some times end them it goes but those codes are saved. Thank very much i would appreciated if you could help me.

Sorry, I don't know....

its probably the crankcase breather pipe located under the air intake split , thats what it was on mine

well, before this car I had a c180 coupe. The oil had worked its way back to the ECU and done harm. The car was running way too rich and I couldn't get it to pass the emissions test. I ended up scrapping it

You can clean everything with electronic cleaner and drill a small hole or two in the ECU casing to drain any oil. My car has oil in the harnesses, but is running fine. I sealed the cam magnets to stop further leaking.

No clue man! Sorry!

I put some oil on them and pushed them in with a drift

@George Donaldson EI7KO what’s a drift

@@dinkringy like a piece of solid metal rod or similar with a diameter larger than the seal. Lubricate the seal first. The firmly push in the seal. Do not hammer it, just push.

@@GeorgeEI7KO thanks George , that’s the last piece of the puzzle, I tried pushing with rods smaller than the diameter of the grommet, didn’t have much luck, need more grommets!! Great vid by the way. Cheers

@@dinkringy they are awkward to get in I have to say. I did film it, but couldn't use it in the final edit as there was far too many swear words. I try not to swear in my videos. Maybe order a set of genuine Mercedes plugs, I bet they'd be a lot easier to fit. Can't see them being that expensive either.

I'm not sure. They came in the kit that I bought.

@@GeorgeEI7KO Thanks.

I bought it via their eBay shop, I've just checked they only seem to be selling them singly now so you'll have to go that route. Make sure you get the pigtails too...

I'm not sure as that's a different engine than mine.

They stop the oil getting into the loom

@@GeorgeEI7KO Thanks . Does it come original or is added or design later on to stop the oil? I bought a pre owned W204 it has one of these pigtails but after changing my camshaft magnets(leaking oil), my mechanic threw away the pigtails as he find it redundant.

@@jjtop20 he dosent know much about mercedes then. They can be bought seperate from the main dealer at a reasonable price.

@@GeorgeEI7KO thanks. I bought the pigtails and fix it already.

@@jjtop20 good man

I filled it by sillicone and im thinking i was right with that

sounds like your camchain has jumped and its the pistons hitting the valves!!!

You are as well off to change them as a pair. In my experience, if one is is bad the other won't be far behind it.

@@GeorgeEI7KO I already changed the drivers site (right site if unstand in front of the car) but the same issue code came few days ago...

@@Leon_MAE has to be the one you didn't change then. The code isn't side specific

it can 'wick' into the wiring and make its way back to the ECU and destroy it...common issue

You must have incorrectly fitted the center plugs. They are a buggar to get in

@@GeorgeEI7KO thanks for the response how do you propose I redo it

⁠the most secure thing would be to replace the engine.

Oil travelled all through the wiring harness before i copped it, waiting on next bit of good weather to do a job on it, then i have O2 sensors, lambda sensor, ecu contacts and alternator wires to clean every few days until oil fully gone 😴

@@havok93 hopefully it didn't make it back to the ecu like it did on my w203 Coupe. Destroyed it. I think I paid a 100 and odd for that kit from auto doc. 276 euro... I only paid 500 for my CLK!

I'm sorry, I have no idea.
