Yellow engine warning light and car has rough idle

The yellow engine warning light on my 2002 Audi A4 saloon stays on, the engine idles rough but doesn't cut out. It has high emissions. If I disconnect the -ve terminal and reconnect it the warning light goes out but reappears within a day. Audi garage couldn't fix it. Can you help?

    Hi, I'll need to check with the garage (unless you can tell me how to find that) - will reply Monday

    Hi, sorry it took so long - took a while to get the code from the garage - they think the trouble code is 11581 - that make sense? They gave me another number 63351 but didn't think that was it.

To get trouble codes you must hook up a test tool called a scanner, this interfaces with the computer in the car and pulls the codes from the computers memory.

I was reversing my audi a4 and i saw yellow light stayed on ,and when i put it in drive it went off.and also giving me a little trembeling


The yellow light is likely not related to the transmission. It's most likely due to something malfunctioning in the emissions control or brake system. You'll need to scan with a VAG COM to find out what the fault codes are that throw that warning.

Audi 1999 a4 runs rough idles up and down


I think the fuel has gone bad. it's cloging the injector ports. Try this first remove all fuel from the tank, replace the fuel filter. add 5 gallons of fuel and one bottle of fuel treatment. Run the engine for an hour
this will allow all of varnish from the bad fuel to disolve and clean the injectors. Don't be suprised
if this doesn't totally elimnate the problem chances are the plugs are fouled and need to be replaced also. Good luck
Hope this helps

2002 audi a4 quattro... a yellow warning light came on the in-dash computer and the clown who sold the car to me didn't include owners manual... any clue what the warning light is and how can i see the...


You have to find someone who can hook up a diagnostic computer to your system. The code should tell them what system is giving you the problem, then you have to narrow it down from there. I have a mechanic friend who does this for me so I have a clue of the problem before I go to my Audi dealer. The engine warning light could be any number of things.

Weird warning light behavior and rough idling.


First of all your car needs too have the battery disconnected but only the negative terminal, usualy black in color if you have caps over the terminals. second wait 10 minutes before you reconnect it. third have a auto parts store hook it up too a code reader, it will tell you everything that you want too know about what is causeing the problems.....most places do it for free as a service.
