97 E300td. After recently being told i had a turbo actuator problem ( lack of turbo boost ), the battery died so I've had a new battery fitted, after which the cars power was amazing. Full power available all the time .. Then i had central locking and boot opening problems and decided to clear fault codes. After disconnecting battery and pushing the brake pedal for 30 seconds, i reconnected the battery. i still have central locking/boot problems and have now lost turbo boost again... anyone have any ideas?
