your key may need re-synching.....lock the car with the key then leave it for 10 minutes, then press unlock on the remote and immdediately open the car with the key, this should resynch it...

anyone got the schematics for an audi A4 b6? i would like to sort out my boost problem but as ive not really ever had the need to me hands on before i havent ever looked into it. also while im at it i have an air con prob as well, the econ light stays on constantly. i dont have a vag com so dont know wat fault code it could be? any ideas guys?


B6 Veteran
The air-con could be a number of things but the econ light constantly on is normally either a high presssure sensor or low on gas, mine is doing the same but vag-com threw up the code for high pressure sensor, i'm just waiting on parts

cool, ill get sum1 to have a look as the pressure of the gas, if its low ill regas if not then ill have to find sum1 with a vag-com to see what the fault is
