Mine seems to do everything as well, had it a good while now. I didn't realise there are varying levels of functionality with them?

Must confess I didn’t either until I started to read the small print , knew there was a difference between the red and white AP200’s

if I remember correctly it should have a min of 19 x service functions for the AP200

really like the other Autel Bluetooth mx808 scanner I have as that goes into alot more functions

Hi All, Replace the Ap 200 scanner for a new one, repaired a leak between the compressor and rear valve block, got the Disco out of Factory mode, previously locked by local garage, air suspension inflates fine, raises to off road height, back to normal, down to access height.
Now when driving fault light comes on HDC Fault, amber I light, error message saying suspension lowering, amber suspension light comes on, go home in limp mode.
AP200 showed U0416-94 Invalid data received from Dynamics control Module
U0421-94 Invalid data received from ride level control module

C1A36-01 Exhaust valve fault
Any ideas on where to look now, wondering if this is middle valve block which has not been replaced
