Audi cam position
This TSB applies to all 2005-2006 Audi A4 and A6 models. One or more of the following DTCs may be stored:
P0014…B camshaft position (Bank 1) – Timing over-advanced or system performance.
P0024…B camshaft position (Bank 2) – Timing over-advanced or system performance.
P0366…Camshaft position sensor circuit (Bank 1) range/performance.
P0346…Camshaft position sensor circuit (Bank 2) range/performance.
The condition may be caused by one or more jammed camshaft adjustment solenoid valves (N205 / N208 / N318 / N319). This may be due to contamination of the hydraulic mechanism of the solenoid valve(s).
Remove the affected camshaft adjustment solenoid valve(s).
Thoroughly inspect the hydraulic mechanism of the solenoid valve(s) and its mounting location in the cylinder head for signs of debris.
If there is any debris inside the hydraulic mechanism, replace the affected solenoid valve(s) and thoroughly clean out its mounting location in the cylinder head.
Do not replace the camshaft adjusters.
If there is no debris present inside the hydraulic mechanism(s), check the correct function of the camshaft position sensor(s) G40 / G163 / G300 / G301 of the affected camshaft(s) with Guided Fault Finding.
