Hi all, ‘I’m new here. Ive got a 2015 1.4tfsi A3. Only done 22000 miles, has run sweet till now. I’m an ex mechanic so I decided to service the car myself and it was a piece of cake; just changed the oil and air filter. Anyway, the car ran fine for a day or so then the other day the yellow EPC light came up on the dash and there is lack of power but runs well, no misfires. I read the codes and it came up with P2279 system air leak. I’d assumed id dislodged an air pipe somewhere but nothing, all looks great. I can’t for the life of me see any obvious issues. When I started the engine after the oil change I did run the engine for a bit without the oil filler cap on, I was wondering if that effected anything maybe? Any ideas anyone? Much appreciated
