Hi guys,
My dad bought a 1996 W202 Mercedes C200 privately just over a year ago. He's had a few issues, nothing unexpected on a car of this age, but we're having a bit of a bigger problem now and could use some advice. Just so you know, the car has full MB service history from day 1, and it's on around 80K now I think. I appreciate at the end of the day it's an old car, things will go wrong, maybe it's not worth fixing, etc etc, but he loves it and even though it's not a massively high-end luxurious car, it really has put the fun back into driving for him. Before this he had a Vectra and detested driving anywhere if he could avoid it - as soon as he got this his attitude changed totally, the auto gearbox has been a godsend for him with his bad back and leg.

Basically, a few weeks ago he said it had started losing coolant, which he noticed right away and obviously kept it topped up. I had a quick look but couldn't see an obvious leak. He did say the car was a bit rough on startup, but I didn't look any further as I'm no mechanic, and not familiar with his car/engine at all. He took it into the local MB main dealer as soon as possible, and they diagnosed a leaking radiator, which was duly replaced along with the rear brakes (unrelated, they just needed doing anyway) at a cost of £800.

He got the car back but the coolant loss continued - not huge, but definitely losing it. Again, no obvious leaks, nothing underneath it if left overnight, or after being driven. He mentioned again that it ran rough on startup, and this time started it for me to hear. It did sound pretty rough for a minute or so before smoothing out, and alarm bells started ringing in my head. I asked him to take off the oil cap, but it was stuck fast, couldn't move it, which was annoying (wanted to check it for mayo). Undid the coolant cap, and there was quite a hiss even though the engine was cold - alarm bells ringing louder now, coolant shouldn't be pressurised when cold. The coolant looked fine from what I could see, but I was suspecting head gasket quite strongly by now.

He took it back to the dealer and this time they diagnosed a leaking top hose, replaced FOC this time. Got the car back and yep, you guessed it - same thing. I repeated my earlier fear that it could be the head gasket, and he booked it back into the dealer last monday. Today, they called him to confirm the head gasket has in fact failed, and quoted a whopping £1650 to replace it.

I find it highly unlikely that the radiator, top hose and head gasket have all failed at the same time, and I strongly suspect that the head gasket has been the cause all along - the radiator and hose were probably fine. Where does he stand now? The way I see it, he's booked it in to fix a coolant leak - they have tried and failed to fix it twice. If he'd asked them to change the radiator, fair enough, I'd tell him to swallow the cost and move on, but he hasn't, he asked for a diagnosis which it seems was incorrect. The bill for the head gasket is substantially more than the car is worth.

I think his best bet is to either try and get the head gasket done FOC by the dealer as they have misdiagnosed the issue, try and get a refund on the work done and get the head gasket done by an indie, or try and get a refund and sell the car for parts/scrap it, buy another car and start over. Do you think he has a leg to stand on here, or is the dealer likely to tell him where to go?

Any help would be greatly appreciated :)
 
Had a similar thing with my focus (completely different faults but same principle) mis diagnosed a problem twice before eventually admitting a bigger fault, did a good will gesture and charged no labour just for parts, would definitely push for at least that!
 
Please don't take a car like this anywhere near a mb dealer again.

It does sound very much like the head gasket is away, take it somewhere else for a quote - suspect it'll be more like 4 or 500 though I'm not familiar with the engine in that car.

Your best bet from.Mercedes may be to push for a refused on the work done -the problem being that whilst it is unlikely the radiator and top hose were causing an issue as well as the head, it is possible.

Thanks for the advice, good to know you had at least a partially good result.

I advised him right from the start not to go to the dealer for anything, full service history on a car of this age is worth nothing when it comes to resale value, warranty, etc, but he's always taken his cars to the main dealer so he didn't listen and ended up in this mess.

I'd expect £4-500 as a reasonable estimate, too, considering I had mine done for £300 including ancillary parts (cambelt, timing belt, waterpump, coolant flush, oil change, etc). The car is still at the dealer's as my dad was on holiday this week, he's going there on Monday to sort things out. Getting a second opinion is something I also advised him to do after the second unsuccesful repair attempt.

I agree, it's certainly possible - but how unlikely would it be for all of them to fail at the same time? Again, the rough running was evident as soon as the coolant loss began, getting worse over time, which says to me the head gasket has been the fault all along and thus should have been diagnosed the first time.

I just really don't want to see him up the creek without a paddle - £800 down for a fault that still isn't fixed, and a car that still needs £4-500 spent on it.
