Help please! For a while my S6's abs light has intermitantly briefly illuminated on overun. A check on the computer indicates that the fault is "torqe output implausable" or similar. The light is accompanied by a slight delay in pickup on the accelerator. This has now developed into a longer (1-2 second) no response from accelerator which is more noticeable. It never happens while power is on, only after lifting off.

Anyone got any ideas as my friendly independent is baffled? Or can anyone recommend a specialist local to Croydon that might help?
