Mass Air Flow Sensor problems of the 2000 Volkswagen Jetta

I am the primary repair person for this vehicle. Over its history, there have been numerous component failures that in my opinion are unacceptable for a vehicle with this mileage and age. I personally know the owner, and know that it is not operated under unusually harsh conditions. The vehicle was involved in a minor cosmetic crash early on, otherwise, there have been no unusual outside factors. At this point, the car has only 37,000 miles on the odometer. Primary use is on long trips. The vehicle is parked and stored for about 3-6 months each year. First problem: air conditioning system leak: the expansion valve failed, requiring replacement. Check engine/ malfunction indicator light: has come on several times, each time with the same dtc, a manufacturer specific code related to the mass air flow sensor. The power windows have failed, ultimately resulting in free repair of the windows with a revised retaining clip, as this problem occurs far too often, and finally, the rear brake pads have worn completely with the front pads in virtually new condition. This is accompanied by all four rotors being excessively pitted, with large areas of the rotor face actually flaking off. My research shows that I may end up needing to replace the rear calipers, as well, due to poor design.

From stop the vehicle would sometime stall. The consumer was unable to accelerate. The dealership was notified, but did not resolve the problem. The vehicle had a bad mass air flow sensor (maf) and was replaced. The dealer found nothing wrong with the vehicle. The driver side door lock did not always lock automatically and would cause the alarm to sound. The problem was diagnosed but the problem was not fixed. The vehicle alarm would sound when the vehicle was started.

Mass air flow sensor failed at least 6 times in the past 60,000 miles, causing the vehicle to stall. Consumer discussed this with Volkswagen, and asked manufacturer for an extended warranty. However, Volkswagen was not listening. The driver's side seat up/down lever spring broke. The micro switch failed and as a result the trunk light and gas light on the dash were inoperative. The automatic door locks failed.

Bought the car brand new from the dealer in December 2000. At 5,390 miles w/warranty took my car in b/c the a/c was having problems. 7,255 miles-a/c is not cold- found system leak-expansion valve leak. 13,247 miles-ac not cold again. Found expansion valve leaking- freon-replaced o ring receiver and drier and expansion valve. 34,684- a/c loud again. 60,760 miles- faulty air flow valve-removed and installed air flow sensor- warranty. 88,850 miles-a/c problems again! 88,850miles- a/c not cold blowing warm air, customer turned a/c on and sqeaking noise heard, turned back off, stopped noise, turned back on blowing warm air and sqeaking noise heard again. Took car in for the a/c problem a total of 8 times! wrote official complaint letter to vw dealership. Manager found the whole a/c system was leaking! manager said it would cost $3,725 dollars! ( b/c warranty has been expired) to fix the a/c unit. They offered to pay for 50% of the price. We are not satisfied. We should not have to pay for anything b/c the vw "qualified" technicians attempted to fix the car, entrusted the car into their care, but eventually led the customer to bigger problems! the car had all the maintenance services done on time! failure of the technicians being able to fix the problem does not show that they are qualified. . What did they check??? why tell the customer that just because warranty expired that there is no olbigation by the service department to take responsibility anymore when they are the ones who have touched the system and attempted to fix it?? bad customer service! unacceptable! already notified the dealer and the president of taking legal action. No car buyer should have to experience this kind of horrible time consuming problem. After paying the full value of the car. Investing thousands of dollars for a new vw car this result is not getting what we payed for. The car does not meet up to the standard of their motto "vw design and intent".
