vw sharan sport 1.9 tdi
i have a vw sharan 1.9 sports tdi on a 02 reg
which is producing smoke form under mid section of the car.
its been back to the dealership 5 times now, first time they said it was the auxilery fule pump at fault, and replaced it,but it still smokes on and off,mainly when cold. there is also a tapping sound from under the car seams to be on the passenger side as with the smoke. The other 4 times it has been back to try to and correct the fault, but it does not do it when they have it in there workshop, so they can`t fix it. I`ve been told that it could be the auxilery heater, has anybody had this problem, or could shed a reason why this is happening.
Any help would very helpfull for when the car goes back for the 6th time!!!
thanks

Well, it does sound like a problem with the auxilliary heater. You might check out some of the threads in the upgrades forum on installing an Espar/ Webasto- style heater. I believe the instructions for the heater include faultfinding.

But the pump clicks, and if it's clicking too much the heater will overfuel and smoke. But why? Controller problem methinks...
