Has anyone made a successful Mercedes goodwill claim on hydraulic lifters? My car has been diagnosed by Mercedes needing the lifters replaced. Car is 58 plate on 72k. I've rang local specialist and two have suggested Mercedes should help with the issue. The original Mercedes dealer said they'd help on cars up to six years old maybe but two other localish dealers have both said they'd apply to Mercedes for goodwill contribution. Also the heads were off last year for the headbolt failure. I asked the dealer to look at the lifters/cams and I was told everything was fine (irrelevant i guess!)

:(
 
Are they tapping all the time or have they gone through ?

A lot tap from start up but quickly go quite. Mine will tap for maybe a second..

My friends car has only 17k on and that has the odd tap sometimes for a minute or so..
 
They're tapping all the time now. The hotter the oil the worse it gets.
 
Does it only happen at or close to idle? My m157 has a slight tappety clatter but it goes away at 1100rpm ish
 
Ah.... Then they do need sorting of they are noisy all the time.


Is it not worth a try with Mercedes ? Will it cost you anything initially to find out ?
 
They've said to me I think £150 for diagnostics at the local dealer. Could be worth a try. I think it's completely realistic to expect the lifters to last far more than 72,000 miles.
 
I'm in the process of doing my own on my 2008 CLK63 at the moment.
if you got an independent specialist to replace them all it shouldn't be a huge bill, the timing chain doesn't need to be disturbed or anything drastic like the headbolts.
Mine started clattering when hot at first, then all the time within a week and I stopped using it as I did not want to destroy the cam(s).
The age of the car would be the factor here, maybe if it was newer you might stand a chance but I doubt you would get much help from mercedes.
Mine lasted 90k by the way.

I think the chances of getting anything from Mercedes is near enough nil.
Due to the age of the car they will say it is age related.
If you are the only owner and have full MB history then you may get some goodwill gesture or at least have an avenue to go down while trying.

I hope you get it sorted soon.
 
Cheers for the replies guys. I think my local dealer was selling me a possibility of getting it done free of charge or at least a contribution. I don't want to pay their £150 to be told no help and the bill will be £xxxx when I could have just got it done cheaper at an Indy. All my local specialist I've rang in South Wales weren't interested in doing to job. There is someone in Bristol I've found who sounds ok.

The timing doesn't get disturbed? I thought it would? It's fairly straight forward job then?
 
You might need cams as well as all the tappets, and yes retime the cams, all easy enough.
Remember the diamond washers and new bolts on each cam so its not a cheap job, might as well do the head bolts at the same time.
Tappets are £18 each.
 
Yes, the timing chain doesn't need to be disturbed as the cam's are gear driven from the central chain sprocket. Nothing is beyond DIY capability as long as you have patience and time.
And like zenman says above, well worth doing the headbolts too while you are at it (assuming they are the older/supposedly dodgy type).
If you aren't that into getting your hands oily then defo give it a miss and pay someone trusted.
 
This is the drive end of the camshafts, to help understand the timing chain being untouched when changing the hydraulic tappets.

Thanks for that. It actually looks not too bad a job. Perfectly happy to get my hands dirty. The head bolts were changed last year so that aspect has been dealt with.
 
It's quite satisfying doing it yourself too, just make sure you've got access to info like torque settings etc, and have a mechanic mate ready to help if required. The required tools for setting/locking the cams is available online cheap, I think I paid £70 for mine.
