Good Day. I have changed fuel sender unit for Audi A4 1996 and it seems not to be working as the gauge needle does not move when the sender is inside the tank. The suprising thing is that the needle m

Hope you used factory sender. Aftermarket senders have contact problems. Audi updated their senders to gold contacts to improve performance. Moving it by hand may force good contact as opposed top free floating in tank

Fuel gauge doesn't move despite milage driven and digital readout for miles left to fill fluctuates up and down. Dealers' computer says all normal with car but I've driven over 175 miles on...

This is the fuel level sender, I can't umderstand why an Audi specialist would even think why its computer related... I worked for Audi/ VW for three years and that doesn't make sense. You can find the fuel level sender under a panel that is located under the rear seat bench.

Hello my audi radio is stuck in safe mode because my battery died.I cannot find the booklet with the four digit code. If I post the radios serial no can anyone please get me the code? Thank you so...

IMPORTANT NOTE: You must have the security anti-theft code for your Audi radio from the car manufacturer, or from an Audi dealer! It's not enough to post the radios serial no for find the code, because it's an anti-theft code.

The sequence of programming for Audi radio is:
1. Push simultaneous "SCAN" and "RDS" keys until on the screen will appear "1000" displayed.
2. Release keys. No more push on "SCAN" and "RDS" keys because otherwise number "1000" will be considered as first safe code attempt.
3. By the #1 key you will set up the first safe code digit.
4. By the #2 key you will set up the second safe code digit.
5. By the #3 key you will set up the third safe code digit.
6. By the #4 key you will set up the four-th safe code digit.
7. Then push again simultaneous "SCAN" and "RDS" keys for confirm this safe code. On the screen will be displayed "SAFE" notice. Release keys! For few seconds a radio frequence will be displayed. The radio is now ready for use!

I have an Audi 1.8T 2002 the temperature guage barely gets over the minimum setting of 50, most audi's I have had the needle goes to the middle (90). Can anyone advise what is wrong I have only just bought...

The most likely problem you have is a partially stuck open cooling system thermostat. The coolant is constantly flowing through the radiator, so its not warming up as required. This in turn will increase your fuel consumption considerably. The alternator needs to be removed to gain access to the front of the engine block where the thermostat is located. Its a fiddly job, but straight forward for a competent mechanic. Another common fault also related with the cooling system is a faulty coolant temperature sender. Again a straight forward part to replace if needed.
Hope this helps you.

Audi ABS breaking system error

if the ABS fault light comes on as you turn on the ignition and control unit can't be accessed with a fault reader then the control unit itself is faulty and must be repaired or replaced. if can be accessed, should store a fault in the memory, most probably in a wire to wheel speed sender. if light comes on only after vehicle is in motion than fault will be a dirty or incorrectly adjusted speed sender.

Audi A3 2002 model auto - temperature gauge not working

The guage and fan speeds work on independant sensors. If you can remove the plastic engine cover and locate the "sending unit" for the gauge disconnect it and restart the engine. The gauge should remain cold and not move. If this is the case replace the sending unit. This should be a single wire sender located in the waterjacket of the intake manifold look in the area where the upper rad hose enters the intake.

May be the clutch master or slave cylinder. Has the fluid level gone down at all? Have a look around the clutch pedal area for signs of fluid leakage. Good luck, Bob.
