Rotted rear subframe




Noticed this when I was replacing the rear springs. I wired brushed off the rust and sprayed with harbor Freight grill and chassis epoxy paint. Bought a used set off ebay cheap from Cali salvage yards which look almost new.
Now looking at this photo i took last year frame looks fine where sitting on the stop plate, not worn like in the photo above.
Guess I lucked out. Wonder if it has to do with where certain subframes were manufactured.
Whenever I work on the car i take tons of photos so i can look at them on the computer screen and zoom in to see if i can find anything.

You then will need to set up a Mercedes Me account. https://www.me.mercedes-benz.com/
From there, you should be able to register your car using its VIN.
I know it's a pain in the ***, but you only have to do it once (until they make a change and you have to do it agian).

The Best of Mercedes & AMG
I'm at the next problem with them, this was nearly 4 weeks ago now and the part is 'still on order' when I rang them today. I asked for written confirmation that its been accepted ect. cause they may just be fobbing me off and decided to start recording the phone calls. They refuse to give an ETA and its kind of frustrating now, if it takes much longer I'm going to have to just buy a new car and sell this whenever they decide to do it.
Do we have any legal grounds or maybe even the motor ombudsman can mediate this? Its bizarre that a fault this big across a selection of models over a decade hasn't been recalled - I'm guessing this is why they're doing it 'case by case' to not cost them millions in recalls and only deal with the people who contact them?

Did you have issues with your brake lines too?
was thinking could it be welded or it has to be completely changed? Below is a picture of the damage. It’s at the right side.

I only came across two instances where they say welding is approved for repairs. I'll show them just for everyones knowledge.
This one looks very limited to only a few certain frames:
Heres one for the middle crossmember area:
Heres something not related I just happen to find it right now. Deals with the trunk stops.
