Having trouble with one of our cars at the moment. Its a '99 Bora with the 110BHP Tdi engine.
The car runs fine, starting and cruising no problem but when the engine is under heavy loads, ie. accelerating to overtake or driving uphill the engine just loses power. Unable to maintain speed uphill and only just able to accelerate on the flat. It feels to me as if the turbo cuts out. The problem seems to occur at around the 3000rpm mark, the car accelerates quite well at that point with a real noticeable drop when this problem occurs. The strange thing is is that it does not always happen, seems to be more random, but only occuring under a heavy load. The other strange thing is that it clears itself by turning off the ignition and restarting the engine, which is not a pleasant experience on the motorway or a fast 'A' road.
I dont really know too much about the workings of turbo diesel units but I am first inclined to think its a problem with pressure in the turbo? perhaps a wastegate not opening?
Any techies out there have any clues?
Thanks in advance.
