First time to change the oil on our 2013 991. I also swapped back to some original wheels that have been on the car and disconnected the battery do do a seat belt change (but had the wrong belts so reconnected it). So, I started off to do a short test drive to check oil levels and within 300 yards, I get 6 or 7 fault codes. I never even went over 25 mph and now I head home, give a little gas and the engine revs up but I don't speed up. Off and on the gas, it maintaines speed. I get in the driveway and the parking brake won't activate. And the rear wing is up. I let it sit for about 45 minutes and went to pull into the garage and now, all is fine other than the TPMS learning the new wheels (which I expected). So, another short drive and exactly the same thing. I posted on Rennlist and everyone said "loose connections, week battery". I charged the battery and all was fixed except one engine fault code. Put in a newer battery, deleted the engine code and took it for a 5 mile test drive. Everything was perfect, no codes. A few hours later, decided to take it to the store and about 300 yards from home, all original codes are back. What's going on?
Apriciate any suggestions. And Thanks!!
