SOURCE: Audi 80e 1991 hard starting when cold

I've owned the same car. Check that the fuel relay 'primes' the system before you start the car. When you turn the key to the on position (all you dash lights, ready to start) you should hear the fuel pump run for a second or two. If it doesn't run you can replace the relay for about $30. If the relay is not the problem, it may be a check valve within the fuel line to the engine. This valve keeps fuel from draining back to the tank when the car is sitting. That way, there is fuel close to the motor when it's time to start. The temp senor was not a bad shot, they were thinking it was bad sensor not telling the cold start injector to run. Obviously not the case. However, the injector itself may be faulty in some way. As long as the car always starts, it's one of these problems, assuming the ignition system and engine mechanicals are in running order.  good luck. JK

You and your key will have to pay a visit to an Audi Dealer for a Dyagnosticcheck and key reprogramme...if you have a spare key try that..my mate had the same problem on a BMW.

Have you checked to see if there is spark at the plugs? If not, simply take out 1 plug (can be any one of them), connect the plug wire to it and just let the threads of the plug rest anywhere on the engine block. Have someone turn the motor over while you are looking at the gap on the spark plug. If your distributor is sending sufficient power, you should see a nice healthy spark! If no spark, then your problem is either bad coil, bad distributor, distributor cap, rotor, or ignition. But first things first, check to see if you are getting spark.

Key loose / does not stick in ignition slot


Diagnosis: Basically, the ignition slot thinks the key is in so the lock mechanism is in place, which prevents the key fob from going in all the way.

Solution: Insert your finger all the way into the slot. Curl your finger slightly so that the tip touches the bottom. Pull your finger out slowly and your finger will "unlock" the mechanism. You will hear a click sound and also feel it being unlocked. Try inserting your key fob into the slot.

I ran out of diesel. put some in and car still wont start


1. The engine does not have any fuel system screw bleeder!
2. The only one way for start the engine is to fill up the tank, then turn the ignition key in "ON" position for 4 - 5 times, wait for 10 seconds between two attempts, without cranking engine.
3. After that push the clutch pedal, (if exists), to the floor, and the accelerator pedal to the floor too. Now turn the ignition key in "ON" position, wait for 5 seconds, and crank the engine for maximum 40 ... 50 seconds. Wait for 60 seconds between two starting attempts, in order to save the battery & starter motor.
4. Repeat the step no.#3 until start the engine.

IMPORTANT NOTE: DO NOT TOW THE CAR IN ORDER TO ATTEMPT TO START THE ENGINE!!!

1991 audi will push start but not with the key. My shop says they do not have the correct tools and the nearest audi dealer is a long long way away. Is there something I can do to fix it myself?


chances are it's a bad starter/solenoid, check the grounding strap from solenoid to starter (exposed braided wire) tend to rot after time

Lights left on, battery totally flat, will not


You've probably flooded it then - TOO much gas in the engine.
Try this charge the battery or use a GOOD one, and beofre yout turn the key push the gas pedal all the way to the floor and hold it there. Then try and start without lifting your foot. Crank for 20-30 seconds at most.
Do that about 2-3 times, then try to start normally.
Holding your foot stops more gas from entering the engine and allows the gas in there to be cleared out.
Flooding is way easy and then can make starting very hard. You have to be aware of this when trying to jump start a dead battery.

Audi A4 key will not come out after turning engine off


did it just start doing this? try to lift the key up gently while pushing in then while holding up pull key out. if that does not work then try reverse of this going down, dont yank on it though. it would really help though if i know when it started to happen. did you just purchase the vehicle and its been doing it, or did it just start. is the car a manual or automatic? let me know so i can unstress you.
