Hi. Not the ideal way for a first post, but I am need of help.
I have two fault codes P001600 Cam-Crank correlation and P034100 Cam Position Sensor Range. The car runs awful at low revs and needs a good cranking to start.
I changed the cam sensor, but still get warning lights and lumpy low rev running. Any ideas please?
You have added to may 00 on those codes.
VAG Error Code: 16400/4096/000022
EOBD II Error Code: P0016
Fault Location:
Camshaft Position (Hall) Sensor (G40)/Engine Speed Sensor (G28), Bank 1 - Incorrect Correlation
Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Timing Issue.
Camshaft Adjuster.
Timing belt jumped.
Timing chain has jumped tooth or chain stretched.
Possible Solutions:
Check Setting of Timing Belt.
Check Timing of Intake/Exhaust Cams.
Check Cam Adjusters as per Repair Manual.Permissible
deviation < -11° CRK or Permissible deviation > 11° CRK.
Special Notes:
North American Region (NAR) specific notes:When found in 2009 Audi A4, A5 or Q5 with 3.2 FSI AVE Engines, please see Technical Service Bulletin (TSB) 15-09-04.

VAG Error Code: 16725/000833/6039/4113
EOBD II Error Code: P0341
Fault Location:
Camshaft Position (Hall) Sensor (G40) - Implausible Signal
Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Wiring/Connector(s).
Camshaft Position (Hall) Sensor (G40) faulty.
Timing misaligned.
Possible Solutions:
Check/Replace all faulty Wiring/Connector(s)..
Read Measuring Value Blocks (MVB).
Check Camshaft Position (Hall) Sensor (G40).
Check Timing.
Tech Notes:
Sometimes and in some models, low battery voltage or a weak starter can trigger a Camshaft Position Sensor code.
When is the code detected?:
The camshaft position sensor signal sent to the Engine Control Module (ECM) during the first few seconds of engine cranking is out of range.
Description:
The Camshaft Position (Hall) Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module (ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The Camshaft Position (Hall) Sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change. When the Crankshaft Position Sensor system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.
