Hello municipality I have bought a Cadillac SRX 4,6 it! The car has 97 TKM down! Is Bj 12/04! unfortunately he may have problems with the AGR because he has been standing longer! Therefore I have some questions and hope that some people can possibly help! Questions: – AGR where does he sit with the car? – with which software can you read out the car? – Sliding roof maintenance. – Is it possible to upgrade with the car USB ? – Is it possible the TV from the car to set up on DVBT-2 ? – Is there any experience with LPG gas in the car? Valves should be soft! I would be happy if you could help me there! Also like PN!!!! I am myself from Münsterland!
