I bought this car used in 2003 and had problems with it since. Esc light comes on all the time. Replaced ignition coils, mass air flow sensor, oxygen sensor, and spark plugs multiples times to try and fix the check engine light that keeps coming back on. It keeps spitting out random cylinder misfire codes. Passenger side window broke. The arm rest hinge broke. The glove compartment hinge broke. Brake lights need replacing constantly. Water pump broke while driving in the middle of freeway and the temperature gauge shot through the roof. A random tube/hose in the engine broke. Transmission problem, could not shift from park to drive. Interior cabin smells like crayon. Very rough idle, need to warm up the car for at least 5 mins every morning or else the car will stall. I noticed if you do not warm the car long enough, you have to press the brake pedal very hard to get it to stop. I can cope with all the above issues but I cannot tolerate the car randomly stalling/engine dying while driving around the city. Lately the car is making weird noises like it ran over a pothole. I gave away the car and will never again own any cars made from Volkswagen.
We purchased our 2001 Jetta 1. 8l turbo wolfsburg edition in Jan of 2003 from a certified used vw dealer. When we drove off the lot, not 5 minutes later, the turbo seemed to fail and we began to lose power, epc light came on, check engine light came on. We immediately took car back to dealer and they fixed problem. Everything ran fine until sept 2003 our check engine light came on, shortly after we received notice that there had been a recall regarding ignition coils. We took our vehicle to a local dealership where they replaced the coils free of charge. This solved the light issue for a couple of months, then it came back on again, this time when idling fluctuating between 700 rpm and about 1500 rpm and stalling on occasion. We took the car to a local garage and they ran a diagnostics, cleared the failures to see if that solved the problem, which it did temporarily. . . Ever since we have been running diagnostics trying to determine why our check engine light keeps coming on, each time the problem is temporarily solved. At first the mechanic thought it was the airflow sensor, but once they looked closer determined it was a different problem. We have had corrosion removed, connections cleaned, and our lambda sensor replaced. Now our car continues to run and idle poorly and sporadically, the car stalls when you slow, the turbo works on occasion, losses power when accelerating, when car first starts it barely moves with accelerator floored, brakes are very sluggish, sometimes really having to push to get car to stop. No one seems to know what the problem is. Everytime we take it in multiple errors pop up, last time there was 17 fault codes, mechanic keeps going down the list of what to check hoping to find the problem. The bill just keeps getting bigger and nothing has been solved. Recently think that the original issue and current issues are one in the same as symptoms are becoming more similar. Help!.
