This bulletin applies to 2009 Audi Q5 models. The MIL may be on, with DTCs P0016 (P0087), P0018 or P0019 stored in the ECM. This condition does not cause engine stalling but may involve a slight power reduction.
P0016 (crankshaft position sensor – camshaft position sensor correlation Bank 1 Sensor A)
P0017 (crankshaft position sensor – camshaft position sensor correlation Bank 1 Sensor B)
P0018 (crankshaft position sensor – camshaft position sensor correlation Bank 2 Sensor A)
P0019 (crankshaft position sensor – camshaft position sensor correlation Bank 2 Sensor B)
If DTC P0016 is stored, P0087 (fuel rail/system pressure too low) may also be stored.
The cam adjuster solenoid may be contaminated. If P0016, P0017, P0018 or P0019 is stored, disassemble the corresponding camshaft adjustment valve (N205, N318, N208 or N319). Swap the solenoid with a solenoid from the other bank. If the DTC is now set on the bank where the solenoid is installed, the solenoid is inoperative. Replace the solenoid. Make sure that the cylinder head opening for the solenoid is clean.
If P0087 is stored in conjunction with P0016, P0087 may have been set by an incorrect cam position, which can be caused by an inoperative cam solenoid.
First repair P0016 and only follow GFF for P0087 if it persists.
