Hi. I have an 03 A4 Quattro, have a problem with an ESP light coming on 5 or 10 mins into a journey. Any idea what the prob might be?

its in your owners manual and on cover of fuse/relay covers https://www.manualslib.com/manual/396576/Audi-A4.html

take to a audi garage befor you do some expensive damage

Could be a bad ignition circuit (from the ignition cycinder)

Hi there:
The "ESP" system helps correct oversteer and understeer by breaking the inner or outer wheel as needed to get the car back on a straight path. When the light flashes the "ESP" system has detected this condition and has momentarily engaged.


The fault can range anywhere basically from simply a failed brake lamp switch to anything like a failed wheel speed sensor,or brake pressure sensor etc. Check first to make sure you didnt accidently push the ESP on/off button on your dash which would cause this light to come on also. If thats not the case then you will have to have the code or codes read in your ESP control module (computer) to see what code or codes are set to be able to diagnose from here.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.


Thank you for using FixYa, have a nice day.

esp light comes on after driving for few minits and goes out when i slow down can any one help audi a4 2.5 v6 tdi 2002

The speedo not working causes these 3 lights to come on due to the speed of the car needed for the ABS ESP to work . Engine management light is on due to the first 2 lights . Happenned to me last night. Dont know what is up with your speedo . You have to reset the lights after speedo fixing as I am uncertain whether they will reset themselves.

Sometimes the issue is with the mechanical vacuum pump off to the side of the ABS/ESP module. It looks like a round silver canister. This issue is all over Google with many possibilities but the one I copied is most common.

abs control module or tcm

you have spiked the computer, you did not correctly jump the battery in the correct manner, you jump the batterry by hooking up the leads from the donor car to the problem car remembering not to conect the negative to the batterry but only to the body of the car, and still you do not crank the car whiel jumping, you wiat 5 mins unhook the jumpers then start, if this does not work you have a faulty batterry. nwo to fix your problem you must by a newcomputer or see a specialised auto techinician who might be able to save you some money.
