Again, great info and kudos again to you guys for posting the info and It does appear that either MB or sonny are the main guys to do it. Sonny has some great dyno vids on youtube so he certainly knows what he is doing.

My rationale on not getting it done is as follows ;

1. Rare - I mean I got the car washed today and there were 3 other pre facelifts and just don't see the issue in enough volume to warrant it.

2. I get the car regularly serviced (twice since bought last dec which as just an out of cycle oil change and the B service recently) and assume (and hope) they check all fluids and in between servicing, if the coolant light comes on, there must be an issue to lose fluid in such a short period of time and would then if needed, spring for the headbolt replacement.

3. Hopefully by that time, it can be rectified as apposed to regularly topping up coolant which probably may mean an underlying issue.

4. These cars seem pretty bulletproof. Most times I have read through the forum with a headline of some issue (not that this relates directly to headbolts), by the second or third line of the post, the owner has some sort of tune or mod and am not seeing too many issues with stock cars.

5. I plan to keep the car for 4 - 5 years and if someone said to me that I will 100% have to pay $5k in that lifespan to change some headbolts or I can have a M3 or RS4 or M5 or XFR with no issues, I still would have bought it as it just simply is the coolest car i believe that you can get being a mid size car with an overstuffed, oversized engine and a headturner that only an italian exotic can match.

6. It appear that MB do assist for even out of warranty cars and even though there is never anything official regarding this, it does appear to be the norm.

Cheers

Not so true on the Coolant light. I had mine come on about 3 months after buying it. Topped it off and never saw it again for 3 years.

I'd be budgeting at least $2k a year on a 5-6 yr old AMG, outside of any major issues.

I showed you the quote I had from MB Bris for 2 new front struts, a power steer fluid tank and front diff bushes . . . Keep that in mind.

If worse comes to worse and something big goes bang, there are 2nd hand engines and gearboxes on eBay for not so silly money.

And better late then never, 09 with 45k on the clock and being towed to dealer today, had it at my mechanic for a coolant leak and have advised either a head bolt or head bolt any cylinder damage. Two year preowned warranty expire last month....f me !!!!!
Any advice re what this will cost if mb don't want to come to the party?

mr747

Sorry to hear that mate what month was your 09 built in??

Sam1977

Not sure mate

mr747

Good luck man let me know how you go speak to Luke at Melbourne Mercedes he might be able to help you

Sam1977

Has he had some experience with this ?

mr747

Sam1977

Helped you in the past?

mr747

not me personally but i know alot of people who he has helped and also ive spoken to him a couple times on the phone and he has always given me great advise over the phone

Sorry to hear and all my fingers and toes are crossed that it gets sorted with a minimum of cost and maximum assistance from MB. May I ask a bit more about the symptoms and coolant leak i.e. have you had the coolant light or had to top up recently or did you notice a puddle on the garage floor ? Just trying to get a reading as I have posted my rationale about buying the car and not worrying the issue based around the fact that if the car is regularly serviced and if a coolant light comes on once, then I would hope that means that even though there would probably be an issue, I can get it to a dealer but I noticed that reading some people's experiences about the head bolt issue they get the coolant light and keep topping up etc for a while before it goes bang.

But again, sorry to hear this has happened and hope to hear how you progress.

Driving along and the low coolont message comes up, I have a look at it at home and theres about 100 ml missing, no biggie I think.
Next time I'm out after 10 mins warning message comes up, I ignore do my usual commute from home/work work/home, at home check again but this time 1.5 litres missing and I think this cant be right. Take it to the mechanics, the put it on the hoist and theres coolont every where on the underside of the car.
After they check it out it appears theres a hose of some sort where coolont is leaking from. After this is replaced they pressure test the car and it uses about 1 litre of coolant in 5 minutes, no leak or coolant anywhere so going straight into the engine.
Diagnosis...not good
Prognosis...t.b.a but I've got my arguing shoes on and heading to Mercedes today for what Im sure will be the first of many trips

HI sam, any news on your issue?

EddiBawBag

HI mr747, did you end up getting this done yet, I'm close to purchase a 09 or 10 C63 and all this talk is making me nervous, i may build the swap cost into the total or go for a MB approved with warranty.

If anyone has actually had a failure please post in the sticky poll at the top of the forum with the details, invoices, etc

If you did mot have one and are in the range just vote uour mileage to date in the same poll

Bear in mind there are over 40,000 units in the range, 13,000 from 2007-2008 alone, which will have higher mileage by now
So far only a hand full of failures, at least documented
