My audi allroad goes into low range by itself and derates my speed while driving

Posted by on

  • kiruben_sath Nov 10, 2012

    The car doesnt really derate but im forced to slow down due to the low range light that comes on with the buzzer. This is a 6speed manual. I have since removed the control unit for the low range which has seemed to stop the low range lihgt from coming on but have abs faults and air suspension faults. Could it be the control unit or a wiring fault?

jack the car up saftely then take the wheels off .. then you will see the brake calipier turn the wheel towards you so the calipier is facing you . at the bottom of the calp you will see a small bolt at bottom undo this and lift prize the calp up then remove 1 pad the inside on where the piston is then put calp back down and put the bolt back in just to hold it in place then when you have done this put a large stronge screw driver in via hole in front to push the piston all the way back but make sure you do the evenly and piston goes in straight or it will get stuck same with all types of brakes. once you have done this reopen calp and take the other pad out clean all area with a wire brush and replace the new pads in place,, and retighten bolt etc , before you start the other side please make sure you pump brake peddle until it goes hard again. then do same to over side ,

SOURCE: 2001 audi allroad air suspension wont lower

I had the same problem, I went to my mechanic and they said that the system has shut itself off due to a problem the computer has seen, in my case it was a selinoid in the pump which released air had failed and had to be replaced, unfortonatly you can not buy the selinoid seperately and would have to replace the entire pump, I was lucky though because he has a spare pump that he pulled off another car which was blown but the selinoid was still good. It took them about 4 hours to find the problem but that was my experiance. DO NOT TAKE IT TO THE DEALER they will charge you for 4 new air bags and a new pump they quoted me almost 5000 Dollers and i got mine fixed for $500

SOURCE: p0431 code on audi allroad 02

Typcally caused by one of the front oxygen sensors or a bad ground associated with these sensors.Replace both front sensors with direct fit type NOT universal, because there may be a cracked wire and the universal sensor does not contain the complete wire harness. Direct fits, are about $20 more than universal fit type.

The O2 sensors have integrated heating elements that bring them up to the proper operating temperature. Code P0431 indicates that the O2 sensor on your driver side catalytic converter is not reaching the proper operating range. The O2 sensors are usually in the $150 range online.

Hold upper and lower arrows at same time for about 10 seconds to activate and deactivate jack mode. OR start driving car and it will automatically deactivate I believe when speeds are sensed above 5 mph.

SOURCE: 2.7t audi allroad gearbox lost all drive except

I had this problem or at least a similar symptom. Check the wiring harness located behind left front tire for wear or brakes. I had a broken wire from the tire rubbing this harhess of wires. when I repaired it, I had all forward gears and reverse. To find the spot, Just look for a spot that the front outer edge of the tire could hit. Hope this helps.

Hi i have a 2003 audi allroad , the suspension in front side is going to low when i stopped for long time , and sometime when i put it into level 3 ,it goes back to level 2 if whem the car is in moviment....


This is a common problem.
Firstly the sinking of a side when the car is left for a while is indicative of a leak in the air bladder on the suspension, it has to be replaced as a unit, not particularly difficult but AUDI prices are high, try Arnotts industries in US, they have a remanufactured unit which is superb. Secondly the suspension system is designed to lowere the suspension from the high ( 3) setting when car is driven for anylenght of time above an average speed ( I think 50 ish MPH on lev3) when the vehicle has been driven for a period under the average to trigger the drop to lev 2 then the suspension should rise again to lev 3. hope this helps

Feels like rear diff is permanently locked on 2002 a6 allroad . particularly obvios on tight turns at low speed


This may not help but it may.Put the car in 4wd and reverse slowly.At the same time switch the car to 2wd.Give the throttle a small rev and apply the brake as you put it in 2wd.Sometimes the transfer case 'winds up' and can,t release 4wd.This may or may not help.Hope it does.
