You will have to have the fault codes read by a code reading machine . That will tell you why the engine stopped. I am suggesting that you check to see if the cam shaft is turning when you try to start it as the timing belt may be broken. Repair/replace items listed by the codes -reset the CPU with the code reader

This problem is with ecu / ecm= engine control computer. These are a common and horrible problem on vw's, particularly on tdi's. The signs in a tdi are when car dash lights come on, but no glow plug light,trans gear lights flash, but car still tries to crank. And hopefully ecu has enough power to out out code u0100= no communication with ecu. Unfortunately the ecu will need to be replacd. The ecu is located under the hood, near and under the wipers. Used ecu with same codes run $50-200. New $1000. If get used one make sure has a return policy. codes must match production quarterly year.

The error code definition reads:

"Catalyst Efficiency Below Threshold Bank 1"





It's possible it might be the oxygen sensor, but it's more than likely the catalytic converter. This is a relatively common code for VW's.

You can google "p0420" and see the posts...

Very difficult. You have to open the inside access door on the drivers side, remove the amp and wheel well cover, pinch the tabs and the bulb cluster will release. The taillight assembly is bolted from inside of the car, so it can't be done outside.

this is a common problem for these cars glow plugs go bad like spark plugs however the smoke would lead to bad mass airflow meter. it is not telling ecu corrcet miss. disconnect mass airflow meter. when cold see if this makes it start better. it should would means you need new m.a.f. glow plug issue take a test light place clamp on positive of battery then pull off glow plug connectors place tip of test light on glow plug the bad one will have a dull light unlike the good one which will be brighter. will need new plugs and wire harness four **** connectors and wire striper and crimper will fix concern good luck

The dealer gets there build info via computer link to the manufacturer data base for paticular car, you can be 99.99% it is correct.
