Air suspension inactive

[SIIX TT]

Had my TD6 about 6 weeks, already done 1500 miles. I put the car suspension on the highest setting over the weekend as I was working on the car. When I drove it on Sunday the dreaded air suspension inactive warning appeared. Is it something Ive done?

I tried to reset it by disconnecting the battery and putting lock to lock on but I fear its a trip to my local Indie.

quiet lot in this section...

Went to the Indie who reset everything and added a software upgrade. He thinks it might be signs of the ABS/ECU.

Where is the best place to source parts?
