Question about 2001 Audi A4

Audi A4 avant 1.8 2001 in limp mode

I have previously posted this problem; The car's camshaft timing had to be set back to where it should be, and then started backfiring into the valves. Setting it back to where it was caused the car to have no power at all. We looked at the exhaust and catalytic processor box, and both were unblocked, the catalytic processor working well. Downloading from the computer is all normal, with no problems indicated. When starting up the car, it is fine, but then goes into limp mode, with no power whatsoever. The power light also comes on then. Please help, any idea what could cause this as there is no blockage in the exhaust and the catalytic processor working?

    I just remembered now that the brakes also had a problem. The pads had been replaced approximately 3 months ago, and when the aircon runs, sometimes the vacuum action of the brakes are not working, it feels as though the car is switched off when pressing on the brakes. This is a random thing, doesn't happen all the time.

SOURCE: A4 2001 1.8 has little power throughout all gears

Mrs Tercia,have you checked whether you might have either blocked exhaust system or Broken and blocked Catalytic converter? What I mentioned are the main cause of loosing power,backfiring and make the car not drive able and possible blow either the engine or catch fire.

I have an audi A4 Quatro avant 1998, the radio is locked SAFE mode, I have the code but I do not know what to do.


How to exit the 1998 Audi A4 radio out of SAFE mode: IMPORTANT NOTE: You must have the security anti-theft code for your Audi radio from the car manufacturer, or from an Audi dealer!
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!

2003 Audi A4 1.8T Check Engine light on


The CEL means there is a Diagnostic Fault Code stored in the Engine Control Unit. There are 1000's of DTC's, so you will need to have it read by a Code Reader. Auto Parts stores like Auto Zone, Pep Boys, perhaps even Advanced Auto often will read the code for you; but by law they cannot clear the codes. Many codes do not cause drivability problems, severe ones will trigger the ECU to run in a Limp Mode, which would require repair work before any trip longer than a few miles. Hope this is helpful.
