My C55 occasionally when booted almost seems to stall then gives a big drive train bang before going like it should.

I do not mean noise bang. More like a bog down then slam in the back before launching. Any clues?
 
If its a big jolt and the delay is merely a split second then maybe a diff issue
It's always better to give a little more info........

From a standing start do you feel a great jolt, and then she is fine???
 
Damn! Thought this was going to be another of your dogging threads...
 
Ok


So pulling off a roundabout in 2nd. Boot down, bog down, then boom. It's like the car is going to stall. Then bites.
 
Local Kids have tipped a Gallon or Two of Diesel in ya tank!
 
Presumably this is something new, i.e. it wasn't like that before?

Have you tried connecting a basic code reader to the ODBII port - presumably you don't have access to STAR?
 
What happens if you accelerate through the gears from a standstill so 1st through to 3rd?
 
Fuel filter blocked ?

Does the traction control light up during this time ?

When was the ATF last changed ?

Pedal sensor ?
