Hi, The auto box on the A Class is cartainly quite a weak point and is very expensive to repair if it does go wrong. It is also very difficult to say how long they will last - they will suddenly fail without too much notice.
The electronic controlled valve body is a common failure and also the clutch carriers inside the transmission can fail - both are extrememly expensive to repair - often to the point where the vehicle is uneconomical to repair with the age & value of the cars these days
I would personally recommend the manual gearbox version of the A Class - these are fairly robust & the transmission provides very little problems other than the clutch may need replacing at higher mileage
The semi auto (clutchless manual) is also an expensive transmission to repair with problems with the clutch hydraulic control module & would avoid this transmission also!
Let me know if you need anything else
Best regards, Paul
I must admit to being a bit disapointed , can you tell me if in your experience A class boxes differ from e class in regard to reliability and are they more prone to failure on a particular A class,£33 to say such a vague answer was not expected ,
Hi - I was not trying to be vague - I have pointed out the common failure points on the A Class auto transmission and the favt that they are often uneconomical to repair due to costs
They are certainly more prone to failure than the rest of the Mercedes models - the transmission is completely different to the transmissions in the rest of the Mercedes models
I am not sure exactly what more information you need?
Could you let me know if you are looking for any more specific information?
