2003y Allroad air suspension anomaly
Hei
Something very strange is going on. It all started after change of front airspring. But it can be just coincidence. Couse it had a leak and pump had to work a lot.
With new airspring there were no problems at town, short distances, but some strange staff started with long distances. (i made 1600km trip)
1. 1 and 2 green level lights starting to blink. They blink 30sek - minute, and after that everything is ok. no warninglights, no error with car height
2. 1 and 2 green level lights are blinking, then it lowers to 1 level and no warninglights
3. 1 and 2 green level lights are blinking, then it lowers to 1 level and yellow warninglight starts to burn at spedometerblock.
4. 1 and 2 green level lights are blinking, then it lowers to 1 level and 2 level light keeps blinking and pump light starts to burn. And it gets back up to 2 level and everything is ok again.
5. 1 and 2 green level lights are burning and suddenly yellow warninglight just starts to burn, and after many km it starts to lower itself.
And many different variants more.
But car can stay many days, it keeps its level- so no leak from airsprings.
Now, at one moment it didnt lift it up at all. Like pump doesnt start at all. Pump made usually some noise, but now total silence.
So
They connected PC at service, but it doesnt show NOT a SINGLE FAULT. Everything is ok. We put a new pump- nothing. Pump doesnt start, then they add some air into system, pump doesnt start. If they connected pump directly from battery, then pump started.
But if we turn ignition on, the yellow light starts to blink, that car is to low, 1st level light starts to blink and the compressor light goes on at lifting button. And it is on some time (1min maybe) and then just turns off and yellow light stops blinking and just burns. But this shows that airsystem ECU is working? some fuses? Pump cables are out of power.
Any good ideas?
