Re: (Caribmon71)
I’m for sure not as skilled and competent on Touareg technicalities as Spockcat, but I’m air-less to and investigated the matter.
In my opinion it can bee done. You need the 4 air suspension dampers, the sensors fitted to the dampers and suspension parts, the sensor under the trunk, the air compressor and air hoses, the air suspension controller module, the wiring, and off course the VAG-COM.
In Denmark the air suspension is rather expensive due to 180% taxes on cars. I’ve gathered some information and diagrams if anyone is interested in learning more. I think the system can be added within a working week.
1. Air supply unit with solenoid valve block
2. Air spring damper, right rear, with Right Rear Dampening Adjustment Valve N339
3. Right Rear Level Control System Sensor G77
4. Level control system control module J197
5. Rear Body Acceleration Sensor G343
6. Left Rear Level Control System Sensor G76
7. Rear accumulator
8. Air spring damper, left rear, with Left Rear Dampening Adjustment Valve N338
9. Front accumulator
10. Left Front Level Control System Sensor G78
11. Left Front Wheel Acceleration Sensor G337
12. Air spring damper, left front, with Left Front Dampening Adjustment Valve N336
13. Left Front Body Acceleration Sensor G341
14. Right Front Body Acceleration Sensor G342
15. Right Front Wheel Acceleration Sensor G338
16. Air spring damper, right front, with Left Front Wheel Acceleration Sensor N337
17. Right Front Level Control Sensor G289

Lets us know more on the project please… I’m trying to pile up some money for the project, and maybe start it by installing the air compressor unit under the car….
