My wife’s 2017 Tesla Model S 100D had a TAS_a217 "Air suspension compressor disabled - Vehicle unable to raise" alert when we bought it last year, and eventually, the rear passenger corner of the car began to sag overnight.

We took the car into a local Tesla service center, and as usual, they charged us nearly $300 just to assess the vehicle. After looking at it for what was probably just a few minutes, they could not find the leak.

As a next step, they suggesting dropping the entire High Voltage Battery Assembly to chase the air lines and look for leaks, in addition to replacing the entire the air suspension valve block. The estimated cost was over $1,500 to do this.

I suspected a simple problem, such as a leaking rear strut, so I decided to do the work at my own shop.

I brought the car to S 3 X Y Auto Service (my independent Tesla service center in Mission Viejo, CA) and we tried Tesla’s method; dropping the high voltage battery to visually inspect the air lines. Of course we found nothing - the lines looked great and had no leaks. The air suspension valve block appeared to be functioning perfectly as well.

It turns out, we would have completely wasted $1,500 if we had taken Tesla’s offer to continue their search for the leak, and ultimately, we only needed a simple $250 part and a couple of hours to fix the problem.
