Thank you Marius!! I spoke with my garage guys - they said they are quite afraid of the amount of labour for taking out the injectors... but it looks like this is the way to go... (I live in a tiny village.........) I'll study a bit - maybe I could try to do it myself... Thanks again! Cheers Vitaly

Hello everybody! I am new to this forum and what brought me here is, as it often happens, a big problem that I can't figure out myself... My lovely A2 1.6 FSI, which I own for less than a year started misfiring about 6 months ago. It started as barely noticeable and gradually it's getting worse and worse... The engine works perfectly for 3-5 minutes after cold start. Then after a little warming up (say, 3-5 km travelled): Works ok at ide. Works ok (ish) at revs >4000 RPM. Noticeably misfires at RPMs around 2000-2500, especially around 50% throttle. Check engine blinks then light up. Here are the errors I am getting all the time: Control Module Part Number: 036 906 013 F Component and/or Version: MED7.5.11 4628 Software Coding: 00051 Work Shop Code: WSC 02138 Additional Info: WAUZZZ8Z53N005638 AUZ7Z0B2098087 VCID: 122DCA0A5E18EB8E3D9-5000 6 Faults Found: 17443 - Sensor for NOx (G295) P1035 - 35-10 - Signal Implausible - Intermittent 16523 - Oxygen (Lambda) Sensor B1 S2 P0139 - 35-00 - Response too Slow 17584 - Bank1: O2 (Lambda) Correction Behind Catalyst P1176 - 35-00 - Control Limit Reached 16684 - Random/Multiple Cylinder Misfire Detected P0300 - 35-10 - - Intermittent 16685 - Cylinder 1 P0301 - 35-10 - Misfire Detected - Intermittent 16687 - Cylinder 3 P0303 - 35-10 - Misfire Detected - Intermittent Misfiring cylinders are randomly different every time. What I did so far: Fuel system: - Replaced fuel filler cap – no effect - Replaced fuel filter – no effect - Replaced fuel pressure regulator – no effect - Replaced Activated charcoal canister – no effect - Replaced N80 solenoid valve – no effect - Used injector cleaning fuel additives several times – sometimes they seemed to have helped a little, maybe… Ignition: - Replaced spark plugs – this probably helped a little - Replaced ignition coils – this helped a lot but didn’t solve the problem Engine mechanics: - Checked compression I did this in a garage – I don’t remember the numbers, but the guys said all cylinders are even and the values are good. - Cleaned up the grounding point behind the left headlight – didn’t do much. Now I’m puzzled where to look next. I attach also here a few logs. Any advice will be highly appreciated!
