jonaska, na dzien dobry wymien filtr paliwa, jest przed tylnym prawym kolem. Wyjmij pompe paliwa z baku i sprawdz jej filtr siatkowy na dnie i bak pod wzgledem zanieczyszczen. Jak nie pomoze to moze byc uszkodzona pompa paliwa w baku, regulator cisnienia paliwa, uszkodzone wtryski, nieszczelnosci w ukladzie ssacym lub wydechowym. Ogolnie mieszanka paliwowa jest uboga.
16555/P0171/000369 - Fuel Trim; Bank 1: System Too Lean
Possible Causes:
Mass Air Flow Sensor (G70) defective
Intake System Leak(s)
Possible Solutions
Check Mass Air Flow Sensor (G70)
Check Fuel Pressure Regulation
Check Fuel Pump
Check Injectors
Check Intake System for Leaks
Check Exhaust System for Leaks
Check Secondary Air System for Leaks
Check Vacuum Pipes for Leaks
Jedyne co jest pewne to przeplywka odpada, gdyz 1.6 16V jej nie posiada.

jonaska,
"You can check your current state of trim by using VAG-COM or equivalent to look in Group 032 (in many modern ECU's, consult your Factory Repair Manual for the specific group for your particular vehicle) in your engine measuring blocks. The first two fields will have percentages. The first field tells the fuel trim at idle (Additive). The second field tells the fuel trim at elevated engine speeds (Multiplicative). Negative values indicate that the engine is running too rich and oxygen sensor control is therefore making it more lean by reducing the amount of time that the injectors are open. Positive values indicate that the engine is running too lean and oxygen sensor control is therefore making it richer by increasing the amount of time that the injectors are open.
It is totally normal for both the first and second fields to be something other than zero. In fact, zeros IN BOTH FIELDS indicates that either you just cleared codes (which will reset fuel trim values) or something isn't working properly. If values get too far away from zero, it will cause a DTC (fault code) and can set off the MIL (commonly referred to as the Check Engine Light, or CEL). Specifications for normal operation are usually somewhere near +/- 10%. "
