Official Mercedes Rear Subframe Extended Warranty (Multiple Models)

^^^^ There you go post, #78 . Heed my warning (post #75) . Get everything in writing and try your very best to agree to pay for NOTHING . Not all MB dealerships were created equal and they seem to se the 'FOC' subframe thing different to each other.
I am digging my heels in but so are they. I put it in an email to them before lunch today that this should be included in the replacement at no cost to me due to it being a manufacturing fault. They haven't replied yet but on a call they said that the rubbers weren't covered by the warranty.

I agree with them that the 'rubber' parts were not covered by the warranty , but they should have made that clear to you at the beginning. And maybe met you halfway with the cost.

TBH the thought of replacing a sub frame and NOT replacing every part with an elstomer/rubber in it on an 'old' car would be daft to me (unless there was proof of them being done recently) .

Not sure about your model but on many MB there is one 'arm' each side that has a bolt fitted in such a way that it is impossible to remove without dropping the sub frame .

Changing those alone (IMO) would be a no brainer if the sub frame had to be dropped.

It's a 2010 C Class 220 Estate. My garage told me that you wouldn't replace the subframe without putting in the new rubbers and that it should be part of it that's why I am trying to fight that battle.

Doesn’t the subframe come with the rubber bushes pre-installed?
 
It does, see pic above/on previous page

Doesn’t include new control arm bushings though, I’m guessing they charge you extra for those

Thanks Teddy. They have said that they have to order the part in so I am not sure which they are referring to. I have asked them to send me a pic of what is needed as first everything was included after full diagnostics done and I needed a new front suspension then when I told them just to do the subframe as my MOT had not mentioned suspension they came back and said when they took off the subframe they could see I needed new rubbers and with the charge for the rubbers replacement.

I got a reply from Mercedes as below:

I think they’re talking about the bushes in the control arms. There’s no way they reused old subframe bushes - the subframe itself has bushes and it comes with them. Visible in the pic on previous page.

You have to remove all rear control arms and suspension, and they’re talking about those bushes (I believe), but best to clarify

Thanks Teddy, they sent me a photo as below of the worn part that they put back in and said the car is ready to pick up but they recommend I get this part replaced.

I'm unfamiliar with a control arm like that, I've never seen the rear suspension of a c-class but to my knowledge nearly all the arms have some kind of a curve in them.

Someone on here should know where that arm lives!

Nothing really to do with the subframe though.

Depending on milage and age, all suspension parts on the C and E-Class cars going in for the subframe probably need refreshing. It's just a matter of cost.

I am planning to drop my rear subframe as part of a whole refresh of the car (the subframe has surface rust only) it makes it easier to replace the brake lines . Putting it back without replacing just about everything I can reach goes against every mechanical instinct I have .

Replacing them all is about as easy as it gets with the subframe out ...they are all attached to it ! As a result i have bought the whole kit from FCP Euro , along with brake hoses, shocks and springs etc.

Still a few bits to collect before battle commences.

What do you mean - you can see the subframe bushings inside the replacement subframe here
Your correct , on this one . The parts catalogue shows the subframe as one p/n and each 'insert' as individual p/n . Could be this is a complete assembly supplied by MB to MB dealerships in the case of warranty claims. ? No idea .
 
You are joking, aren't you?

Good on MBUSA for standing behind their (failing) product.

Brickbats to MBUK for continuing to pretend the problem doesn't exist.
Just had my W212 fail it’s Mot on the rear sub frame. Car is 2012 and looks mint externally and internally. Unfortunately brake lines failed had these done at local garage. Took for Mot and mechanic invited me to look at the subframe! He advised me to call Mercedes which I did. First, Stockport who were so difficult to deal with on the phone I tried another main Dealer after being on hold 4 times and eventually cut off!! I am happy this occurred though as I called Mercedes Warrington who booked me in for an inspection the next day. Result was car deemed unsafe and I was told they would seek approval from MB to replace the subframe. Cut a long story short this was agreed and the Dealership kept the car and gave me a lift home. They had a subframe instock ( Stockport quoted 6 weeks) and hopefully I will get the car back Monday having left it with them the Thursday before. Super service from Inchcape Warrington MB. Very well looked after and relieved MB will cover the cost. Recommend this dealership no problem. Ladies on the reception and service desk both fantastic.

Stockport - they really are abysmal. So disappointing considering could have become the centre of all things Mercedes in the north given great site location and space but their customer service service both phone and branch, sets new levels of incompetency.

Ironically, Warrington do seem to be much better on the occasions that have used them.

Great to hear that all sorted out.
 
My e class w212 also failed it's mot last week on crack on each side of rear Subframe they told me they had same problem but on c class only a few months earlier and they complained to mercedes main dealer and got it replaced free of charge. So I was on the phone to Doncaster MB dealer while my car was still up in the air at the mot garage and they told me to take it in ASAP. They recommended that I dont drive it anywhere apart from straight to them so I did and they were amazing. I left it with them and the next day was phoned saying good news we're replacing it but unfortunately it may take upto 6wks then 10mins later was phoned again by them saying more good news they have one in stock and my car will be ready for this Friday and it was last Friday I dropped it off. I've also asked for them to put a full mot on it seeing as it's ran out now and they've agreed. So I'll post again when I pick my car up 👍
 
The kit comes with a small pipe piece which can be inserted into any hollow hole. Should be able to spray a far amount inside as long the pipe end can be pushed through enough. When I do mine, will take some photos before and after. I forgot to mention, the downside is the liquid ideally should be reapply the liquid once a year but I'm okay with that as it doesn't take long. I was a bit dubious but it definitely not a snake oil product and will help prolong as much as possibly 🙂

A lot of Freelander2 owners recommended Lanoguard. For them it's the rear wheel arch/sill area that writes many cars off.
 
On my 2011 s212, Mot in December called out sub frame corrosion and servicing inspection has recently confirmed a hole that Mercedes has agreed to cover the cost of the repair.

Anything I should watch out for on its return?
