E220 CDI Engine Mounts

What we need is an inflation busting , cost of living crisis answer .

Think outside the box !

I'm sure expanding foam will work.

 

[Tonygw]

expanding foam, definitely worth a try!

I have been considering changing my mounts for some time now, my local merc indy quoted £400 using genuine merc parts. (thats just changing the engine mounts.) The right mount is an easy change but the left mount near the dpf is a bit more involved so they quote a bit more labour for that one..

 

[Gazwould]

What's the score if + transmission mount ?

 

[Tonygw]

I had the transmission mount changed by a none merc specialist last year, they charged my £38 labour, I think the lemforder mount was about £30 from autodoc.

Yeah i reckon thats the easiest one to do. The rest of them are a bit difficult and the drivers side one requires the dpf or some exhaust components to come off in order to remove the mount. Also in the om651 the plastic sump means you cant jack the engine from underneath whatever info i found online seems to suggest it being a 3-3.5 hour job to change all 3.

Parts arrived today from autodoc. All seems good been comparing the Lemforder mounts i received with images of mercedes original parts online and they look identical down to the markings and numbers printed on the parts which leads me to believe that they probably are the same thing that mercedes use in the factory. Infact the gearbox mount has the mercedes logo ground off on the lemforder version vs the original (see pics)

I did read somewhere on another forum that while lemforder might be the oem that doesn't mean the after market parts they sell are of the same quality as the ones from mercedes this is because they have special agreements in place and it would be illegal for them to sell the same product rebranded as aftermarket the post also suggested that lemforder use a different rubber formulation when manufacturing parts for mercedes. Not sure how far all this is true, why else would the logo be ground off if they weren't exactly the same.

...why would the logo be ground off if they weren't exactly the same.

It is, because they are. Some people only ever buy Mercedes-branded parts at Mercedes prices 'because they're better'. The rest of us apply common sense...

Sensors and actuators should never be bought from aftermarket or even OE quality. Yes same company, same assembly line and yet different. MB requires very specific tolerances and OE parts don’t have them, proven a million times over. If you really wanna save money, buy OEM for a bit more instead of cheap first plus OEM after you realize it’s not working.

But for the rest of your statement, I’m 100% with you.

That sounds rather like an 'everybody knows' statement. Do you have any examples to refer to?

 

[Notamech]

Oh really? That sounds like an 'everybody knows' statement. Do you have any examples to refer to?

Everybody knows you dont need examples for an 'everybody knows' statement.

Oh really? Buy an ABS sensor as OE quality and see how you’ll get an ABS/ESP not available message. Buy an OE MAF Sensor and see how your engine doesn’t run right. The OE Bosch MAF Sensor is 0,4 V off and your ECU goes haywire. So before you call me a Mister know it all, check facts and learn first. I can go down the list of sensors,... You’re welcome

 

[E55BOF]

I didn't call you anything; I'm just asking what evidence you have. 'Proven a million times over', eh? One faulty Bosch MAF sensor only leaves 999,999 to go...

So you wouldn't buy an ABS sensor made by Bosch, the OE supplier, then, except from MB, in an MB box, at an MB price?

Let's have your list of sensors, then. Leave out the Chinese-made stuff, though; I agree with you on them.

I think we all know MB (or any other mass producer of vehicles) buy almost everything in when it comes to sensors/brakes/wheels/tyre/seats/elastomer mounts/suspension units, etc , etc . The list is endless.

True , on many occasions they might specify a bit more of something or other to match or exceed their QA standards. But buying stuff without the MB star on it is never really an issue as long as you (as stated) stay away from the obviously (normally Chinese) carp that is out there.

 

[Tonygw]

You have to be careful as there is an awful lot of counterfeit "branded" product out there from China.
You may think your buying a Bosch sensor but its easy to get caught out with a counterfeit. I would stay away from ebay and the like and stick to the known reputable distributors. Its a real problem these days.

I do see where you are coming from. While anecdotal, the forums are filled with people who have tried aftermarket sensors only to realise they don't solve the problem. Whether they got caught out with a fake or if the calibration was off is anyone's guess. For me personally for any engine, transmission, emission related electronics or mechanical components I would definitely only buy original MB even if its just for the peace of mind that I wont be caught out with a fake.

I did engine mounts on my CLS 250 CDI, which is an OM651. It was simple in principle, there were only two issues. One was how to undo the top bold on I think the right hand side as you are working on it. I had read about the offset spanner as above and tried it for ages without success, but in the end I used loads of extension bars and a universal joint and did it from the top. It wasn't that hard that way. The other issue was actually removing the mount once the bolts were out. I had to jack the engine up pretty high but it came out.

It helped a bit, but didn't make it super smooth. Engine was raised up though - the strut that holds up the air intake pipe was sitting on the fan cowl originally, but now it's about 5mm up. I am having issues with the air intake pipe and the engine cover vibrating and knocking now - that is audible, so check that out.

Thanks for the reply. I am going to have it done professionally this coming week. I thought about doing it myself but id have to invest in quite a few tools. Also if I mess it up il end up spending more

I completely agree.

I have just acquired a pair of front discs for the E Clsss. Mercedes quoted well North of £200 plus needed 10 days to get them in.

Car Parts 4 Less (Euro Car Parts online only retailer) had Brembo (OEM to MB) for £150 and as I placed my order I was given a new customer discount of 20% so I paid £120 delivered.

The discs look identical to those fitted except the Brembo discs are actually painted in the vented areas and around the hub part

So finally got this done today cost me £324 labour with vat and as mentioned previously £146 for parts so £470 all in. In terms of the difference it made i think my previous mounts were definitely a bit worn but still had some life in them as now the intensity of the vibrations i experience has gone down quite a bit but it still exists so I assume this must be normal for a diesel car. Also engine on and engine off now has nearly no shake. Nor do i experience vibrations in the seat when stopped at a signal so definitely some difference. With my petrol car don't feel anything at all to the point where I can't tell if it's on. So conclusion is if youre experiencing some amount of vibrations in a diesel car its probably normal.
