Fellow aussies, who has suffered this problem? What did your dealer do about it? Was your C63 still under warranty?
I approached my dealer and they have refused to change the head bolts or acknowledge there is a problem. I would like to get this fixed before something occurs to my car as it is out of warranty.

Thanks

Check this thread out, I believe MorganB is a fellow Aussie with recent experience, I think he was just out of warranty too. You will also see the TSB in the thread below that you could potentially show your dealer.

Mine is in for a service today and the service manager said that they are not proactively replacing headbolts, only applying the fix when something goes wrong. I have a 2 yr extended warranty through Mercedes Approved program and have been told I'm covered under this if a headbolt issue arises.

Thanks jas il follow it up

Remember, it looks like it is only a few C63's that have had the problem. You may well not have an issue. Wayne Swan reckons he can fix everything, send it to him if it plays up. Mind you, if he does to your car what he did to the economy then your car is doomed. ROFL

If Wayne swan touched my car it would turn to gold, then he would tax the **** out of it, apparently re invest it into the community so it returns a surplus how ever fail to deliver!

The way MB charges for parts I think Wayne Swan is already head of the spares dept and applying some extra "taxes" to us.

I dont know why you think they would replace something that hasnt failed? why dont you ask them to replace some other perfectly functioning parts and see what they say regardless of car.

I think people become paranoid thats all - C63's here in Australia aren't a cheap investment $100+ for good second hand units, and for that kind of money I guess people want some peace of mind.

But your point is valid for sure...

Have studs installed. Order them from weistec, shouldn't be too much coin, considering the value of cars there.

mr747

So have u had any issues fingers crossed mines been ok so far

RNS-11Z

A brand new c63 in aus optioned up costs near on 200k! So to risk blowing the engine with a known issue that can be rectified before it happens is wise in my opinion. Although my car is problem free, it falls into the range of the engines affected. So I'd like to to take action before it happens.

What is the range of vehicles affected?

Also, how much for weistec (apr?) head bolts? and then how much typically for install? that's a big job isn't it?

mr747

if u are going the super charged route I would change them while I had half the engine pulled apart if u are leaving ur car the way it is I'd leave it

I know ur car has done over 60k if it was gona happen it would of already happened but I'm not a mechanic

As you will note in the other thread mine was about 6 months out of warranty, only 51,000 KMs, perfect MB Service History and serviced by MB less than 2 weeks before the head bolt failure. MB Aust covered some (the majority) and I had to contribute (essentially engine in and out). I would think the older the car get the less inclined MB will be to contribute. It took a long time to narrow down the problem and then to get MB to help contribute, possibly 4-5 months overall.

RNS-11Z

Yeah my car has done 72000kms. There are some future mods planned but not supercharging. Im more then happy to pay some of the costs included in changing to the newer head bolts. If I can convince my dealer il get it done through them other wise I'm going to have to go the aftermarket route and go with the weistec optiona

Valvestud

Any MB with an M156 engine with an engine serial number with the last five digits lower than 60658 are affected.

Why did it take them so long to narrow the problem down?

JaseC63

This is a good question, I'd like to know what the actual process to do this is, seems like good insurance and going by MorganB's experience if it comes in under $5k it's probably a good deal.

The price of the headbolts isn't too bad, think the last time I check Weistec they were $800USD or in that range.....I think the labor to get it done would be where the real cost lies.

mr747

My c63 is a 2010 and my last 5 digits are 57311 so are u saying my engine is pronoun to the headboard problem???

Where did u get that info from??

RNS-11Z

There is a stick thread on the main page of this forum. Have a look through it. It's listed

mr747

Well I just read it not good lol well I'm up to 60k and I drive the car like I stole it and so far no probs hope it stays like that if the head comes off I will be changing them

Let me know how u go with the dealer h

Valvestud

Is the "57311" that last digits of your VIN or your engine number? If it's the engine number, then yes you are in the affected group.

Regards,

Joe

mr747

He joe yes u are correct it's the engine number it is what it is

It may have a problem it may not

Read that 100,000 M156 engines were produced for all MB applications. The 5 digit sn range kind of suggests this. We cannot seem to develop a count on affected cars which is a shame. Right now the forum members are statistically "noise level" to MB who is stonewalling and leaving it to dealers to administer "secret" and "goodwill" warranties to some. This is unlikely to change IMO because most M156 owners simply throw money at the service departments and suffer (or enjoy the "marque") in silence.

ShaneN.

Where does one find the engine number, if I want to look for this when looking at cars? Although, if I'm looking at 2009s/2010s then I'm almost for sure in that range anyways, right?
