W204 subframe issue

[Wizard1992]

Hi all

Just after some advice, hopefully some one may have previous experience.

My w204 (1.8 kompressor) had been making a knocking sound, then last week or so when ever I braked the back end would pull out.

Jacked it up this morning and found that the Nearside rear wheel has pretty much corroded away from the subframe.

Not ideal, does anyone have any idea what a rough ball park figure would be, I've also heard that the subframes may be covered under goodwill from mercedes but I'm expecting this require some effort.

Cheers

The last one we did was around £1400 fitted, that included some of the brake pipes etc.

Yes, Merc will probably cover it, though it might require a bit of pushing or trying different dealership chains, as I gather they can vary in their approach.

It is the same issue as https://www.pistonheads.com/gassing/topic.asp?h=0&...

Mercedes will almost certainly the subframe FOC although they might charge a bit for the nuts and bolts.

There was a guy on the MBUK forum who had his 2005 I think, SLK280 subframe replaced by Mercedes recently.

He took it to Mercedes for a post purchase inspection and they told him it needed a new subframe at a cost of about £4k but all replaced by Mercedes FOC, but he did pay about £250 for the various nuts and bolts etc.

It is a very common issue, they rust from the inside out so very difficult to spot until the basically break apart as yours seems to have done.

Thanks for the advice all!

I'd be quite happy if all i had to pay 250 quid on all honeslty.
I'll make a few enquires during the week at my local dealers and see what they say

A quick update

Mercedes agreed that they would change the subframe FOC but I would be liable for new bolts if they needed replacing ( ball park figure of 500 quid according to the dealership )

Had a phonecall Friday that the track rods need replacing at a cost of 850 quid as they are completely seized.

When I asked if this was in addition to the 500 pound for bolts they said no new bolts were needed and it was 850 just for the track rod ends which to me seems excessive

Do the trackrod ends require doing to do the subframe or could I get the trackrod ends replaced at my indie once the subframe has been replaced?

Thanks

Track rod ends are on the front presumably.

The subframe is at the rear.

Seems like the dealers way of getting the cost of the subframe back from you with what seems to be some very expensive track rod ends.

I would get an Indy to do those.

[E63eeeeee...]

Presumably they have to do an alignment once the new subframe is on, hence spotting the stuck track rod ends. But I'd at least get another quote.
