• Kontrol edin: Engine Speed Sensör Okuma Değerleri (G28)

VAG Grubu Özel Servis Notu:

The Engine Speed Sensör Okuma Değerleri (G28) is also used as a reference sensor for the crankshaft position and correlates with the Camshaft Position Sensör Okuma Değerleri Bank 1 (G40) and Camshaft Position Sensör Okuma Değerleri Bank 2 (G163). When an engine will not start due to mechanical (spark/fuel/compression/timing) related issues it is not uncommon to set a false G28 fault codes due to extended cranking with a no-start condition. When found in a VW Golf/Jetta (1J/9M) or Audi A3 (8L) with 1.9l TDI-PD (AXR), check TPI 2007067 which explains issues with electro magnetic interference. A modification to the wiring will fix this problem, extensive details can be found in the named TPI. Even though this TPI was originally released for VW Golf/Jetta (1J/9M), a customer of ours came across the same issue on an Audi A3 (8L). When found in a 2004 VW Golf, Jetta, or New Beetle with 1.9l TDI-PD (BEW), check for TSB 2010461 (01-07-45 formerly 97-05-03) or 201463 (01-07-44 formerly 97-05-04) calling for a flash update to the ECU and a secondary ground installation. General note for any engine type: Kontrol edin: the wiring to/from the sensor and engine control module to rule out harness and module damage due to engine oil or coolant from a failed sensor or tensioner. This is an example from a 2012 Tiguan with Coolant in the ECM which resulted in G28 DTCs in addition to intermittent stalling.
