320d 130kw e91
Please help with my 320d 130kw e91 on the following problem:
2 months ago I was on a road trip to Poland. After approx 300-400 km my car's throttle suddenly disappeared. I was pushing gas pedal, but car was moving very slowly. RPMs in 4-6 gears would not go past 2500. It felt as either the turbine was dead and/or the car electronically went into some limp mode. When going in low gears, the car could go to 3000-4000 rpms, but slowly and I think without turbo. I went to get a diagnosis and got following error codes: 3FF0 and 483D. They correspond to mass airflow sensor and throttle actuator errors. Now my polish friend with a mix of russian and gesture language told me that maf needs to be replaced and the throttle actuator error is caused by maf. The following day we woke up and I started driving, but the car was magically OK! So because Maf sensors were unavailable in the area, we kept driving witthout any fix, because throttle was ok again. We finished the whole trip no problem. After a few weeks, back in Lithuania, the problem repeated. And same fix- after a few hours the car runs ok again. I took it for a diagnosis again, it showed same errors. But the lithuanian mechanics started saying that there might be more to it- that actually turbine might be bad, or the throttle actuator and they need some time to inspect the car. Now the question is, do I let them inspect the car and spend my money on that, or just be the maf sensor ?
