Problems with 2002 Audi A4 ELECTRICAL SYSTEM

On october 28, 2002 the 'air bag' light came on. the car was scheduled for the shop on october 31, 2002. the morning of that date as the car was started the engine was running very rough. i proceeded to take the car to the shop. once i arrived at the shop i informed the service manager of the new problem of the engine running rough. at this time he informed me that one of the ignition coils was faulty. the vehicle has been in the shop since. dt

I have been in contact with close to 100 other 2002 audi owners through the audiworld website and the coil pack problem is a serious issue. the coil packs have been failing on at least 10% of the 2002 vehicles and audi says they are all isolated cases. when they fail the car barely runs and can create alot of personal safety issues. i want them to recall the vehicles and replace the remaining coil packs. please help.*ak

Car lost power, then engine died. i am reporting this because i know of more than 30 other owners of this car that have had the same problem. see http://forums.audiworld.com/a4gen2/msgs/144120.phtml for more info

Ignition system failure on low mileage new vehicle. concerned about reliability of car and safety should system fail and disable the car in dangerous location. dt

No summary listed for above vehicle. *ak

This is a more common issue then audi will admit, many people have had this problem and audi still wont replace all 6 ignition coils (they replace them on a as needed basis).*ak

Ignition coil failed on highway. car "shook" violently until stopped in parking lot. once car was off the road, the coil housing caught fire. the fire ultimately burned itself out, and the car was towed to the local dealership for repair. the dealership notified audi usa of the defect and recommended vehicle replacement. audi usa elected to repair car under warranty. multiple failures have occurred since (see list). ts

According to reports on audi forums, coil packs have been failing at an alarming rate. there is one per cylinder, and people have reported successive failures. audi of america will only replace the failed item. there should be a recall, and all the defective items replaced at the same time.*ak

Consumer states that the ignition coil failed, causing engine to stall. *slc

Coil packs are failing on many of these cars. i had to have 2 fail before they would replace all 4. these should be recalled if this is happening so often to so many. *ak

Electrical system: ignition - two ignition coils failed and had to be replaced. was on freeway in fast traffic when coil failed. car slowed down abruptly and two cars behind had to swerve to avoid collision. ts

While driving at any speed and with no warning headlights will go out and will not come back on. dealer notified.*ak

Consumer states that the ignition coil is defective on the vehicle. this causes the vehicle to lose engine power and the engine light will come on. *mr consumer stated that the manufacturer replaced the ignition coil, but the ignition fails repeatedly. *yh

Homelink system stops working. dealer reprograms the system (which i had already done 5x), and it still doesn't work. the visor with control buttons is ordered & replaced. the homelink starts working again. 7/2002--homelink starts acting up again--it is working intermittently. 8/2002--homelink transceiver is replaced and it starts working again. later that month, it begins working intermittently again. 9/2002--dealer finally investigates further, and finds corrosion in the wiring harness/connectors. that sounds very strange to me. what was the car exposed to during production to cause that? what else is going to fail/give us problems as a result? *nlm

The ignition coil wire has gone bad causing vehicle to start but then to shut off. dealership notified. please provide additional information. mr

Left stranded by ignition coil failure on 2002 audi a4 1.8t - this is the second time stranded by this failure

Engine coil failed on 2002 a4 1.8t at 10,600 miles. per audi, replacement part is on national backorder for approximately 2 weeks. indicates that this is a more widespread problem than audi is admitting. when coil fails, car becomes unsafe and undrivable; engine barely has any power. huge safety issue for driver and other cars on the road should the coil fail while car is in use. audi is not proactively replacing all ignition coils when a vehicle presents with one failed coil. audi would not provide price quote to me for replacing remaining coils in the vehicle at my expense (also, they have no available parts to do this, advising that they only have supply to replace failed coils). i do not believe this car is safe to drive until all coils are replaced. please demand that audi research this problem and initiate a recall to repair all impacted vehicles. dealer advises that they are seeing increase in number of vehicles presenting with failed coils.
