2002 Audi Allroad

2002 Audi Allroad with 138k miles. Custom wheels and tires riding on bilstein coilovers instead of air ride. Custom cat back thrush exhaust, fender flairs are faded from gulf coast heat. Timing belt changed at 110k. New plugs at 123, liquid moly 5-40 every 6k. New aux water pump and headlights replaced,
Everything works, temp control will default to metric on shutdown and CEL on due to CAT low efficiency, bank 1 and 2, due to high flow exhaust. NO OTHER CODES however. One rear backup sensor alarm in bumper bad so gives false alarms. Tried reaching it but couldn’t so disconnected system. Really nice ride, runs great.
