Mercedes-AMG 45 Stalls
Discussion
I purchased an AMG 45 which was still under warranty and had low mileage, the vehicle has still only done 12k and is now just out of warranty.
After refilling the fuel tank with petrol, the vehicle has had an intermittent fault of refusing to pull away cleanly and on occasions has completely stalled. Sometimes taking 3 or 4 minutes to restart the engine. Very embarrassing and dangerous situation, especially when trying to filter on to a main carriage way with other vehicles.
I reported the issue to my main Mercedes Benz dealer, who examined the vehicle but could not detect any fault. Needless to say the fault persisted and a few months later when the vehicle went in for a major service, I again reported the fault to the Mercedes Benz dealer. The vehicle was still under warranty.Again the dealer couldn’t detect the fault. Needless to say again the fault persisted and recently I took the vehicle back again to the main dealer for further examination.
Apparently, the dealer has carried out extensive tests on the vehicle under the direction of Mercedes Benz UK and Germany. The outcome of which has been Mercedes instructions to replace the fuel tank and a carbon particle filter. No technical reason has been offered by Mercedes as to why such drastic action why this should be necessary on a vehicle which is now only 2 months out of warranty.
Mercedes have refused to honour what I believe are their warranty obligations (I reported the issue twice while still under warranty) and are offering to only pay 50% of the costs, leaving me with a bill of £ 828.00 pounds.
I understand this issue with the AMG 45 is not uncommon and I have an acquaintance whose had the same problem and in disgust, ended up selling his vehicle.
I would be very grateful to hear from anyone whose had a similar experience and where I stand with the warranty. Mercedes Benz Customers complaints has proved useless.

It's not an issue I've seen written about elsewhere. The way you phrased this :
Have you tried the AMG lounge where MB/AMG customer services often jump in with help?

made me wonder if you ran out of fuel?Have you tried the AMG lounge where MB/AMG customer services often jump in with help?
Thanks, but definitely not. Always refilled with premium grade petrol and I never let the tank run low.
The problem occurs after refilling and as I said I’m aware of one other person who experienced the same issue and subsequently sold his vehicle. Mercedes are replacing the fuel tank and some permanent charcoal filler but offer no explanation as to why this should be necessary on a vehicle which is nearly good as new and only just over 3 years old and not observing their warranty obligations. The fault which is dangerous was reported twice when the vehicle was still under warranty and wasn’t fixed!

Absolutely they should have paid for it that is annoying but IMO £800 for a fix on such a high performance car is nothing. Once a car like that is out of warrantly and a few years old it's not going to be cheap to run if anything goes wrong
Has it fixed the problem? If it has & you like the car you would be cutting your nose to spite your face to get rid now
All cars have issues and some dealers / brands care more than others
It's a s
t state of affairs but I'd suck it up and enjoy your motor

I’d push for a full warranty pay out dig a little deeper.

You probably need see if you can get the Dealer on side with you here. MB may well decide to hide behind there being no failure found when the car was in warranty and therefore drawing the conclusion that "if we can't find a fault then there isn't a fault."
I've been this way myself with MB over a continuing problem that they were not going to work on at their cost after the warranty had expired!!!
Go to Delaer, sit down with the Service Manager and Dealer Principal and get them to agree that you brought the car in whilst it was under warranty for a problem that they were unable to diagnose - get them to agree that there was a problem during the warranty period. Then get them to take the case back to MB.

Thanks for the reply but basically I have already been down the that avenue. The dealer is basically on side and agrees that while the vehicle was still under warranty, it was brought in twice to have the problem cured but the dealer couldn’t find fault.
It’s on this third visit (6 weeks out of warranty) that Mercedes issued instructions to the dealer carry out various tests and the test reports went back to Germany. The conclusion is that Mercedes informed the dealer to charge the fuel tank and a carbon filter, which is not a service part.
I believe that Mercedes are indeed adopting the attitude that as no fault could be found on the first two visits, then they don’t have to honour the warranty claim. I think that this totally unacceptable, it’s obvious that a fault has always existed and it’s not my fault that the dealer couldn’t find the issue. In fact, the dealer still doesn’t know what the issue is, he’s only acting under the direct instructions of Mercedes.
What’s also now annoying is that Mercedes have provided no technical explanation as to what the issue with the car has been or that replacing the tank and filter will even cure the fault. The dealer informs me that they’ve had the same issue on another AMG 45 and a friend informs me that he knows of someone else whose had the same problem.
It’s just not safe driving this vehicle and I’ve no idea where Mercedes are coming from!

Carbon canister would be suspect. The other name for it escapes me. It makes sense though given the problem happens after refuelling. It can also be made worse by over fuelling. Whoever owned it before you must have gone beyond the clicks at the pump when filling it up or used cheap fuel/not driven often. The fuel tank is therefore also likely to be full of crud.
