hi guys I'm new this so please bear with me....i have an 08 335i auto sports pack. today i fitted downpipes and an asr fmic.everything went well drove the car for about 30 kms no problems and then out of nowhere i got a whole lot of faults pop up on the dash. they were

1.dsc failure
2.dbc failure (not sure if that's correct but something to that effect)
3.tyre pressure monitor failure

so i pulled off the side of the road switched the car of and then put it on again all faults where gone so i continued driving, after about 15 mins it happened again.i currently besides the dps and fmic have a frc flash tune

please if any one knows what could be the cause of this or have any suggestions it would really be appreciated

thanking you in advanced

sorry forgot to add im running catless dps and a custom made catless exhaust, on the 02 lambda sensors there are o2 mini cats installed

Sounds like they unplugged a sensor on one of your front wheels during the install and forgot to hook it back up.

thanks so much for your speedy reply...is this sensor something that's visible and where could it be located...sorry for all the questions

That's a limp mode fault from the torque limit being exceeded.
