Change oil light came on, stop driving. took car to a repair shop, they changed the oil, then left the shop, car died. repair techs said it had thrown a rod, and needed a new engine. we bought a Jasper engine which was installed. engine is fine. has been checked by 5 different places. however, in the last year, it's been drivable maybe 3 weeks total. now we can't drive it 10 miles before a sensor light comes one and the car shudders. when i turn it off that's it. it won't run. have to have it towed to a shop. sensor lights vary from brake pads, to change oil. to check engine.. every time i take it in someplace, they run a diagnostic, and reset the sensors. one place to me i needed the computer flashed, but the VW dealships i have taken it to seem to not know what that is. I still owe money on this car as i bought it used, and it is very frustrating. i can't seem to get anyone to find out what keeps causeing the sensors to go off. can someone please give me some help on this. thank you.

Does the smoke occur all the time? If it is present just after start up and then goes away, it could be no problem at all. There is always some condensation in the exhaust at start up. It is more noticeable in cold weather.
However, if it is there constantly, and you are losing coolant, it could mean there is a headgasket problem. Watch your coolant level and watch your temperature gauge. If the coolant starts disappearing, and the car starts overheating, stop it immediately and get it to an auto repair shop. Driving a car with a bad headgasket can cause major engine damage.
Is it on when you are driving, or only at a stop when the car is idling? If it is more than at idle, I wouldn't drive it, as the engine may not be getting enough oil to lube it all and to help it stay cool. The oil pump needs to be changed in that case. It may be a bad oil pressure sending unit also.
First find out how to reset the light, many vehicle automatically have this programmed to come on at every 5,000 miles to remind you to get an oil change. If that doesn't work take it to autozone and have them put the diagnostic tester on it and give you the error code, it's free, and this may give ou an explination.
I would check the oil pressure sensor and the oil pump itself. You can take the sensor out and use a mechanical gauge to check the oil pressure. If the oil pressure is within specs, you need a new sensor, if not, you need a new pump.
I note that you posted your question 14 Feb 09, so happy belated Valentine's Day! Anyway, I own a 2004 VW Passat 1.8 and am currently facing the same problem (EPC light and check engine light on) and subsequently, I coded it out, which was P0322. I took my other vehicle (more reliable) into the VW dealership in Olympia Washington. I was going to replace the EPC sensor, which typically handles what is sent to the car's brain, telling it how much gas it needs to run. However, the technicians at the dealership told me to code it out before investing any money without knowing exactly what should be replaced.
I took the code and determined the "crank sensor" was defective. If you call around, you should be quoted anywhere between $48 and $90 respectfully. If your VW was lurching like it was missing for a split second at a usual speed, or died at stops, then I would say you were experiencing the same problem I was having. Hopefully, this will fix your problem? The part is pretty inexpensive, but I think what VW charges to replace the sensor, is highway robbery. Anyone in your family mechanically inclined? Good luck!
