Hey guys, recently purchased a 06 xc90 with 113k miles at a local auction, when i drove it from the auction to the emissions office (25miles mostly HWY) it presented no issues or any lights came up, after it passed emissions leaving the emissions office i light came on that said Brake is not disengaged , i checked and the brake was full disengaged, i turned off/on the engine and the light went away but then in lower speeds i started to get pulls like the tranny is beginning to fail, took it directly to a friend mechanic who owns a shop he put his fancy obd reader and more than 20 codes popped up, including where chk engine light and mileage tampering, anyone had a similar experience where after a passed emissions your vehicle started to have issues?

At this point I think its cheaper and more effective to re run it at the auction.

 

Unfortunately now you know why the car was at the auction.

Some of those transmissions are known to only exhibit problems after being driven for 1/2 hour or so. Clear the codes and sell it at the auction if you can.
