Hi guys, reading your posts I wanted to chime in about my 1.8 TSI 160HP BZB engine from 2008, having problems with "mixture too lean" and all sorts of related errors like: P0101 - MAF Circuit Range/Performance P0299 - Turbocharger/Supercharger A Underboost Condition P1946 - Control Module 1 for Coolant P1951 - Radiator Fan 2 Movement Restricted / Jammed P1948 - Control Module 2 for Coolant Fan P1950 - Radiator Fan Movement Restricted / Jammed P1945 - Control Module 1 for Coolant P0171 - System Too Lean P0300 - Random/Multiple Cylinder Misfire Detected P0304 - Cylinder 4 Four Misfire Detected P119A - Fuel Pressure Sensor (G247) : Malfunction P3138 - Intake Manifold Runner Control: Regulation Deviation I got those related to FAN due to a little accident, in which my car swallowed a hawk on the German Authobahn. A/C still working though. In VDCS I see adaptation for fuel at idle only at around 21% (channel 33). Couple of days later, check engine light gets on, because ECU cant compensate more. Then I see P0171 (too lean) sometimes together with P119A (g247 malfuction). I replaced the sensor to the OEM one, no change. Weeks later I see a number of additional ones: P0101, P0299, P3138. I did clean the MAF and the aribox recently and swapped the air filter to the K+N one. When it gets cold, this issue is getting dramatic - I get misfires and engine just shuts off right after ignition or in the traffic. I guess that's knock control that says his to do so. Because the issue is mostly prevalent at idle, I suspect an air/vacuum leak somewhere. But I've checked all (I hope) the hoses for hissing sound, touched them, squizzed them and found nothing except one kinda leaking but I'm not sure what's that, could you guys help? The engine is running rough at idle - especially when it's cold. Sitting in the car is like being pushed forwards and backwards because the engine "wiggles". It also rattles kinda like a diesel to me although couple of mechanics in Germany and in Poland including Dealer said it's normal to them. 1.8 tsi rattling? I thought of changing chain but 093 value 3 says -2.7 degrees so it should be OK. This value changes from time to time to -5.7 I don't know why. 091 value 3 and 4 say both 34 kW - at idle. 141 value 4 - Fuel pressure at idle is around 39-40bars, although spec found on Russian internet says 50 - 150bars. Two mechanics said there is no spec for BZB Knock control: Channel 026 2.0 V 2.4 V 1.4 V 1.7 V Output tests say my CAT is down - it was alright 6 months ago, I guess those misfires and lean mixture killed it recently. What I found too is that the hole engine is covered in oil.. I guess that's an expensive job, right? Any comments are very well seen
