Audi Q5 transmission fault

Q. The engine on my automatic Audi Q5 sometimes cuts out when I brake at junctions. My garage says the unit is fine and the stop-start is switched off. Any thoughts?

A. First, check the transmission fluid. If the level is OK, there may be a fault in the gearbox. Audi’s tiptronic automatic unit has a clutch (to avoid drag on the engine) and if it is slow to disengage, the engine can stall. On the S tronic unit, the clutch pack or flywheel may be worn.

Also, the engine may have an overlooked fault, so consult an Audi specialist.
