I'll guess to say the O2 sensors (switched or in the wrong positions.....) Volkswagen will tell you that it's a system 2 error...which then you'll have to bring it in for a full diagnostic .....hummm $$$$$$$$$ (no thanks) I've got the same problem right now and can't seem to get a straight answer without spending a bunch of $$ to have it diagnosed. This problem with the p1128 code occurs when you have a bad mass airflow sensor because this problem happened to my VW Jetta 1.8t and i first changed the o2 sensor and the code poped back up so I finally figured the problem was my mass airflow sensor.. guaranteed a %100.. good luck and thank me later. ok i know this sounds basic and a bit patronising but the p1128 code means Long Term Fuel B1 System Too Lean i currently work in the motor trade as a fuel specialist including over 12 yrs with crypton, sun, bosch tuners, rolling road, turbos, chipping and frequent weber and bosch for tech update training,
