You make it sound like it's our fault you can't find it :>D

The start of production of the Audi A4 B5 is 1994. With minor changes, it was produced until 2001. At first, only the sedan version was available, the station wagon (Avant) appeared a year later. This material provides information on relay circuits and fuses Audi A4 b5 1994, 1995, 1996, 1997, 1998, 1999, 2000, with an assignment of their elements and locations.

Can't get much clearer than this. Relay 4 is one plus 'Additional Relays 23 and 24. Plus fuse 23 and 24.

the timing chains are located at the rear of the motor requiring a transmission removal to replace
If the chains need replacing and the guides and tensioners will be close to needing replacement that is an added cost to be considered
ask service agents and accredited service centers who work on Audi how much that procedure costs

hi i need help with my audi a4 quattro 09 .. how do you change the belt tensioner pulley ? i been tryna look for the diagram but cant find anything..please help

The brown wire from the downstream sensors is broken or otherwise not connected to the computer. Check for damage to the wire.

The serpentine belt routing diagram for 1998 Audi A4 Quattro 2.8 liters V6 engine:



CS = Crankshaft
F = Fan pulley
Gen = Alternator
T = Tensioner pulley
AC = Air Conditioning
PAS = Power Assisted Steering

463A definitely not VAG codes they are from one of the cheap code readers.
Audi A4 Quattro - fault code 463a: engine control unit disabled.
This could be a dirty sensor or bad connection somewhere.
The immobilizer light flashes when you insert the key?
Imobiliser pick up loop in the steering column sounds dodgy, take the cowling off & check its connected ok. Just clipped it back in.

no. suspend engine with engine brace and lower suspension.

a rubber one,should be changed at 50-60,000 miles. Audis recomendation is like 90,000 I think but have heard of them going much sooner than that. A preventitive Cam -timing belt job way cheaper than doing it after it breaks and ruins valves and cylinders!

Here is a manual, but you have to purchase it:

AUDI A4- 2005. There is a technical service bulletin for this exact problem. take it to the dealer when this issue has happened while driving. During a daytime drive when cold see if you cant get the light to fail while circling your dealer. As soon as you pull into the service drive do not turn the car off do not flip the switch. I am an Audi Technician for a dealer in Birmingham alabama. Personally this is not my favorite repair to perform; What audi states is that if the bulb flickers the bulb should be replaced; if one side fails the bulb should be swapped left to right if the fault continues with the bulb the bulb is at fault; if the bulb is swapped and the bulb fails again on the same side it is the module. NOW: I currently am working on a 05 A4 that both bulbs both modules have been replaced and Audi has no clue what to advise on a repair. THIS IS AN ISSUE if it has happened to you ask if there is a TSB for this issue or try to find it for yourself.
