Someone please tell me it's an easy to get, easy to change part. At this point i don't care how much it cost, I need my car back. Did i mention there aren't any audi mechanics here...freaking awesome.

are very easy to change. Pump you have to get under the back of the car, module is above rear driver's side wheel accessed from inside the car by removing trim panels. if you can hear the pump running I'd start with the module, sounds like that's your problem. when my pump went it never ran again.
good luck

Did you ever try to perform the "system filling" function?

newsouth78

never heard of it, is it a function throught vag com?

want

System filling (allroad)
Vehicle must not be standing on its wheels during filling of the system (if a repair at the spring system was performed before), otherwise the air spring will be damaged!

It is possible to perform filling of the air spring system without having to loosen mechanical connections.

System filling via On Board Diagnostic (OBD) must only be performed with the vehicle standing!

Note:

The air spring system (pressure reservoir, air springs, pressurized air lines) can be filled using the VAG tester. For this, the valid limit values are: Air spring 9 bar / pressure reservoir 13 bar.

System filling is performed in stages. (air springs, front / air springs, rear / pressure reservoir)

Filling is only possible after manually switching off the regulation. Switching off and on of the regulation is performed with the VAG tester (Fct. >10, channel 10) or via manually pressing button for up and down (press button twice > 5 seconds).

Time frame for filling is limited to 65 seconds. However, it is possible to perform the function several times in sequence to accumulate a longer filling time.

It is possible to perform a filling procedure in stages using the up and down arrow buttons of the VAG tester. ( buttons 1 / 3 of VAG1551 tester have the additional assignment - button / - button )

Procedure
1. "login" with "08367"
2. "basic setting" from group 026 to 031.

Note:

However, the filling procedure can only be aborted prematurely by exiting the display group number.

- Disconnect diagnostic cable from Data Link Connector (DLC)

Other filling procedures can follow in the above mentioned scheme. the order (filling air springs - front axle, air springs -rear axle, pressure reservoir ) can be specified as desired.

Note that upon exiting the filling mode, the regulation still remains manually switched off, as long as it is not switched on or a speed of v > 15 km/h is recognized.
