general problems of the 2003 Audi A4

Water pump failed inside lights sometimes work and signal lights aren’t accurate.

Left turn signal works fine. Right turn signal alternates between flashing left and right.

The coolant light came on after I replaced coil packs and I stopped to look wasn't leaking anywhere. Drove to work and it caught on fire due to overheating I guess not really sure. I was driving a car on fire down a highway and didn't even know it. I stopped to take a left turn into work and smoke stared billowing out and around the entire car. Other drivers couldn't see me or nothing I could have been in an accident. The fire department checked the car out sort of and it's in a mechanics shop now. Trying to figure it out. Oil light was on and that's it. An then the coolant light would kick on and off. Nothing else after I changed the coil packs. And it was well after I did that.

Initially drove car home from grocery store hit a bump and noticed a spark coming from front driver's side of car. Pulled over and checked for spark evident once stopped there was no sign of spark or anything. Got car home and parked about an hour later my car was on fire, after putting the fire out my husband lifted the hood and tried to investigate the issue when he discovered the battery was melted to the hood and is where the fire initially caught. The location of the battery we believe to be the issue and wanted to make sure to report it immediately.

Radio intermediate goes out hitting bumps speedometer stopped working the number ninth digit is not pulling up when I search vehicle information replaced engine vehicle only had 20,000 miles.

After returning home from a drive through fast food place last night my daughter was parking in our driveway, she was in reverse. The car (a 2003 Audi A4 cv convertible) bounced and made a sound then she stopped. I said take the keys out of the ignition to her black smoke started to rise out of the top of the hood crack in front of the front windshield. I told her to get the dog in our back seat and herself out I assumed it was on fire because the dark smoke. I grabbed my purse piped the hood and my daughter called 911 as the neighbors ran inside there home for a fire extinguisher. Two men from across the street attempted to put it out as I spoke to the 911 operator. The fire department arrived and got the fire out. My car is now junk. My daughter was emotionally strained, hysterical throughout the incident. It was traumatic for us both. The firefighters said it was possibly caused by electrical malfunctions.

The contact owns a 2003 Audi A4. The contact stated that while driving at 35 mph, various electrical functions of the vehicle shut off and the steering wheel seized. The engine warning light illuminated. The failure occurred once. The vehicle was taken to an independent mechanic where it was diagnosed that the transmission control module needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 200,003.

Headlight keeps going out and blowing the ballast causing headlight not to work at all. Replaced this expensive part multiple times and still breaks. Not a cheap part and a safety hazard.

Car left headlight failure (hid/xenon). Fault not with bulb or fuse.

The contact owns a 2003 Audi A4. The contact noticed water in the foot wells on both the driver's and passenger side of the vehicle. When he started the vehicle, the electrical system went haywire. The dealer stated that the electronic control module was flooded due to clogging of the intake plenum drain grommet. The contact was advised to have it cleaned in order to prevent future failures. The manufacturer stated that there was no recall for his year, make, and model vehicle. The current mileage was approximately 37,000 and failure mileage was 31,342. Updated 8/7/09 updated 08/11/09.

Engine box floods after driving through long distances in heavy rain. Results in car that will not run at all (needed to be towed) diagnosis is that the engine box floods from insufficient drainage from the cowl which then shorts out the engine control module and transmission control module (basically the car's computer center) this is the second time this problem has occurred (both after driving through difficult rain storms) the first time this happened was in October of 2005, and it took nearly 6 weeks to diagnose and repair. Repair was done by authorized Audi dealer that originally sold me the car. The final bill was nearly $5000. They insisted it was a fluke and had me make an insurance claim to cover the repairs as flood damage. I made a formal complaint to Audi at that time since it is clearly a design flaw. (someone the dealer acknowledged to me that they had witnessed this before, each time telling the customer to go through their insurance to cover the cost). Here I am less than 3 years later and the same exact thing happened this weekend. I drove through an intense rainstorm and I have a flooded engine box. The bill is once again going to exceed $4000, not to mention the amount of time that I will need to rent a car (again) to conduct my business. I sell real estate and depend on my vehicle. Once again I phoned Audi customer care and lodged another formal complaint with this issue and they refuse to acknowledge this design flaw. I am currently seeking legal council in order to recoup these costs. I have both complaints which are exactly the same filed with Audi. I do not have the first set of parts, but I can certainly keep the ones that have recently failed. At this point I do not have a car, I am waiting to see if my insurance company will again pay for this claim. I truly believe this is something that Audi needs to take care of and acknowledge the flaw.

Forgot to install c clip on temp sensor on radiator hose which popped out causing major engine damage and blown head gasket which was denied for many months. In oct. 08 they forgot to tighten bracket which caused wires to smoke and fire. Aug 08-trimmed serpentine belt rather than replaced and car stopped running in middle of interstate. Sept 09 replaced oil pan but forgot to put plug back oct 08 oil residue on damper they threw out and did not replace. They forgot to put bolts back on sub frame and miracle I was not killed. This caused axle problems. When they replaced bolts they did not have bushings in stock and they released car without these bushings which is a safety violation. When bushings came in they refused to work on our vehicle and we had to go to different mechanic. They told us we needed timing belt when the headgasket was blown. Now there is new recall for coil packs and they refuse to work on our car. The new gm is listening to the service mgr. Who is not telling the complete story nor is the new gm reviewing the facts. Our lives are in danger with this vehicle and since we still owe $15k we cannot trade it in. Started June 2008 and continues until today. Coil packs which were just recalled are causing car not to run and we are stuck.

I purchased a brand new 03 Audi A4t quattro in June of 03. The dealer is great and thank god they value their customers because my car has given them alot practice on everything. I think germany sent us a dud! since buying the car I have needed various items replaced: a new computer, (replaced by the dealer), a new fuel system was needed because my car stalled in the left lane of a highway while driving in the middle of nowhere (later recalled by Audi but after I needed to be towed and have the cpmponent fixed along with other items supposedly attached to the sytem), and most recently 2 separate problems that have not yet been fixed but have occurred within 1100 miles of each other. First diagnosis of the noise and shimmy while driving was tire balance and later rack and pin steering and after all that they are trying to figure out what the shimmy at 65mph + is along with the whinning in the car the first 10 miles fo each day (after it is warmed up or even if it is a warm day). And what supposedly was first thought to be a coil is now a mystery. They have had my car for over 2 days and are still unsure as to what is going on. Thank god I bought the extended warranty!.

Audi A4 2003, the clutch failed at 30,000 miles, but Audi refused to fix the problem until it was completely undrivable. I had to pay out of pocket because it was categorized as wear and tear, thus not covered by Audi's least. The electrical system and the fuel pump also failed and needed to be replaced. The jack broke while changing a flat tire and I was told that this had happened to other Audi owners, but still had to pay the damage to the plastic siding out of pocket.
