Question about 1997 Volkswagen Eurovan
My 2002 VW T4 2.5TDI has developed a nightmare fault. It occurs whenever it feels like it, on start up, during braking or simply travelling in a straight line. The engine simply 'trips out' and revs at 1200rpm, the accelerator is useless and does nothing. It can be reset, albeit temporarily, by flicking the key or restarting the engine. On my journey home from work tonight it happened 6 times at various intervals, it's only 4 miles. Sound familiar to anyone out there? 24 cans of Stella to anyone who can help me out.......................
I find this fault only happens to my 2001 T4 if I leave the van downhill and it is raining? When this happens I leave it facing up hill over night and the van runs fine untill I leave downhill in the rrain. Very strange I also have changed the pedal but its starting again.

It sounds to me like it's going into "limp mode" - Google it! It's a kind of "get-you-home" setting when there's something wrong. You will need to get the fault codes read (or do it yourself with VAG-com software on a laptop) and then take it from there. It needn't be an expensive problem - maybe a split air hose in the turbo system - or it might be a dirty MAF or stuck vanes in the turbo itself, or any combination of 1300 other things. Main thing is - don't go replacing things willy nilly! Get the fault codes (aka DTC's) read first. An interface cable costs about £15 and the VAG-com software can be downloaded for free.
Hope this helps you a bit. If it does, a "Fixya" rating would be much appreciated. If it doesn't
help you, I'd be grateful if you didn't bother with a rating at present - they can't be increased later if I do manage to solve your problem! Just come back and tell me what you found.

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
