 The check engine light on my 2001 audi a4 quattro came on and was running somewhat roughly. i called the dealerships service department and they told me to bring it in. on the 8-mile freeway drive the engine caught fire and destroyed the engine. *tr

 1. both times, car was being driven normally at around 30-40 mph when, without any warning at all, the car completely stopped from it's speed to zero mph immediately, engine dies and all power was gone from the car. all attempts to restart the car were unsuccessful. it is not a battery issue. this car is very well maintained to all manufacturer's recommendations with oem parts used for all services which are all done by certified technicians at the dealer or reputable independent shop. 2. occurred first on sunday 4/27/08 and again on 5/1/08. we are very lucky that it happened when we were on quiet subarban streets and not the highway otherwise with the car coming to a sudden and complete stop there could have been a very messy accident. imagine going from 65mph to 0mph without any warning on a rush hour freeway. please investigate this very thoroughly. 3. after first incident, car was taken to reputable audi auto repair shop that replaced an electric wire, electrical connector and ignition switch. mechanics' claim to have found power supply cable to the ecu with excessive resistance, traced the wire and found a bad connection in the harness connector. by-passed connector and now the computer is communicating ok (copied from mechanics' operations and parts report). this took the mechanics' 3 days as they said it was a very freaky, unusual and hard to find and solve electrical problem. clearly this did not work since the car again suddenly stopped 5 hours after the alleged fix. now have towed the car to audi dealership. 4. after first incident, called audi client relations u.s.a. to inform them of what we thought was a major safety risk to help make sure it did not happen to others in the future since it could lead to a very messy/fatal accident(s) but they were not at all interested since it is outside warranty. *tr

 I leased an a4 2001 audi in december 2000. my lease runs out in march 2004 and i'm looking at what my rights are as a consumer. over the last 6 months, i've had my car towed and repaired twice for ignition coil failure as well as my tires replaced from out of whack alignment. today, the engine light appeared again and i will drop it off at the audi service department, this monday for maintenance review. fortunately, the only costs i've incurred are replacement of the 2 front tires. it currently has 33,000 miles on it.

 2001 audi a4 1.8 turbo at 99.1k miles. the timing belt prematurely napped while the car was traveling in a busy morning commute causing car to disabled on the freeway. the timing belt failure caused extensive, additional damage to the engine that estimated to coast about $6000 to repair. i have all my maintenances done at the audi dealers and follow all the recommend service by audi. i was never been recommended to replace the timing belt on my all previous visits for maintenance service. the recommended timing belts replacement by audi for my model is 105k miles. both audi dealer and audi denied been in responsible for the timing belt defect and/or incorrect timing belt maintenance recommendation which subsequently result the engine damage and provide any assistant. according to audi, they do not guarantee the timing belt will last to 105k miles, only that it is their recommendation. *jb

 Tl*the contact owns a 2001 audi a4. while driving 55 mph, the vehicle lost power and shut off. the vehicle was unable to be restarted and was towed to the dealer. the dealer stated that the timing belt snapped. as of july 30, 2007, the vehicle has not been repaired. the current and failure mileages were 99,000.
03/02/200794000110/21/2003
 2001 audi a4 1.8 turbo: the timing belt broke while the car was traveling in heavy, rush hour traffic causing the car to be immediately disabled and stopped with no opportunity to move the car off of the highway. the 3-lane highway was backed up for 6 miles while police and emergency workers worked to tow the car. the disabled car led to a very dangerous situation with traffic backed up for over 1-hour on a 3-lane highway with a 55 mph speed limit and could have easily caused additional accidents. the timing belt failure caused extensive, additional damage to the engine that is estimated to cost about $5,000-$6,000 to repair. my audi a4 has the same 1.8 t engine and item (timing belt) as in the 2001 vw 1.8 t and that item has been recalled. the timing belt defect in the 2001 a4 appears to be quite well known to the two audi dealers that i frequent. since i bring my audi in for service at the regular intervals - and since the timing belt issue is well known to audi - i would have expected the audi dealers to bring this issue to my attention so that we could have replaced the belt as part of regular preventive maintenance. the fact that this well known problem was not handled in preventive maintenance led to a very dangerous traffic incident and caused extensive damage to the vehicle's engine. *jb

 Dt*: the contact stated while driving 50 mph on the interstate, there was a popping noise from the engine compartment followed by a lost of all power. the contact managed to pull over without incident. the engine would not restart and the vehicle was towed to the dealer for inspection. the dealer determined there was a hole in the engine and was unable to identify what caused the hole, however a new engine replacement was necessary. updated 5/10/2006 - *nm

 A4's have a poorly designed cam tensioner that eventually leaks oil. the cost to repair the item is approximately $1000. the dealer (carousel audi) even admits to the fact that it is a poor design and there have been numerous complaints about it at the dealer. i've also read numerous complaints about it on audi forums. the leak typically found shortly after the warranty period has expired. i feel strongly that this should be a recall on all respective cars to have it repaired! *nm

 '01 a4 2.8: (1) digital display is blurry and cannot fully understand everything the computer is displaying, (2) internal oil seals have become defective causing a foul burnt-oil smell within and outside the vehicle, (3) transmission downshifts very hard and rough, (4) very poor design by the engineers to place a cupholder directly over the stereo and heater instrumentation which have caused my buttons to stick. have taken the vehicle to various dealerships and shops and technicians have stated that the seals are obviously a design flaw and so is the display panel with has some software or lcd problems associated with it. *ak

 Malfuntion indicator had been on before i deployed to iraq and was still on when i came back. i brought it to the dealor for the $50,000 mile scheduled maint. less than 2 months later, i started the car at a store and heard a loud pop, the engine started idling hard and was very noisy. i was able to drive in first gear the two blocks to my house but the car was very shaky. the spark plug had shot out, there was oil and grime all over it and the threads of the cylinder were stripped. my friend in the car, who has worked on porshes before, said i was lucky this happened when it did because if i was driving on the highway at a high speed, i probably would have been seriously hurt in an accident. the cost of repair is estimated at $5100 and the dealor said that there was no tampering with the spark plugs for almost a year so this just happened due to wear and tear. the car is 3 years old and most the miles are highway miles due to several trips cross country. i am nervous to think what will go wrong when the car gets a little older. *ak
