I hope somebody out there can help as the VW agent in France cannot locate the fault and seems not to have any idea what to do next.[/FONT][/SIZE]
The first sign of a problem on my 1996 Sharan TDI happened when the vehicle was started from cold and was being tested for emissions, the revs on the engine were taken quite high, the engine then started to miss and white smoke came from the exhaust it then stalled, after several attempts the engine started but was missing badly, by letting it tick over it eventually cleared and started to fire correctly, since then when the ignition is turned on the glow plug warning on the dash illuminates then goes off almost immidiately.
Since then the vehicle has been difficult to start from cold also thick white smoke come's from the exhaust on over run (using the gearbox to slow down ) then when attempting to accelerate the engine would miss then stall, it was found that if the clutch was depressed and the engine allowed to tick over it was then possible to pull away as normal.
When the vehicle broke down on the motorway it again emitted thick white smoke from the exhaust but when the clutch was depressed the engine stalled and could not be restarted.
The following parts were tried, tested or replaced in the UK to try and overcome the problem prior to the breakdown, number 3 injector was removed and tested, it was found to be working correctly, relays 109 and 103 were removed and replaced but this made no difference so the originals were refitted, the timing was checked and found to be correct (new cam belt fitted), the fuel pump pressure was also checked, the crankshaft sensor and tempsender were also replaced.
The car has now been in France for three weeks :zx11:, I would be very gratefull for any help you may be able to give.
