The suspension system is ABC (Active body control / hydraulic) if it is a 600 and it definately has a pressure sensor they are common to leak and we keep the seals for them in stock. with the SDS you would click on whatever code it had in memory and it would lead you throug a guided fault test. ADS refers to the shock absorber adjusting system on this car. What was the car actually doing or not doing? there is a service bueltin for random lowering that is related do defective acceleration sensors. I have seen about 5 of there and they are hard to diagnose unless ou know what to look for. Steve at continental will finde the problem.
