    Hey everyone I have a A4 b7 Quattro 2.0t 6mt, I installed APR stage 2 and the car ran great for about a week and a half then I got check engine light. When I checked the codes it gave me 4 of them, p0444 (evaporative system purge control valve circuit open), p0243 (turbocharger/supercharger wastegate solenoid A), p2400 (evaporative emission system leak detection pump control circuit/open), p2294 (fuel pressure regulator 2 control circuit).

    The cars rpm's do not fluctuate and it still runs, it does not go into limp mode at all. The check engine light went away but the codes still exist if I run a diagnostic. During start up it does rattle a bit but don't know where it's coming from, could be the cam followers in the hpfp. I did install the eurojet pcv kit and it does have a cai as well. I've checked the fuses under the ecu and they where all fine. I've also checked all electrical connections and still can't figure it out. It's odd that all 4 codes came on at the same time. I'm hoping someone else had this same issue and can point me in the right direction. My head is spinning out of control with this issue. Please help! Thanks in advance everyone!!

    Man I figured there would be some 2.0t tech gurus here. No one has come across or seen these codes as a lump issue. Well at least we tried to figure it out.

    Check fuse called S345 in ECM box at the plenum, it is 15 A fuse, it should be blown. All those components are getting power from fuse S345. Hope there is no short circuit.
