The definition
00515: Hall Sender / Camshaft Position Sensor (G40) - No Signal.
What to check first
Cheapest and fastest checks first:
- Check the oil level and when it was last changed. These adjusters run on oil pressure and are the first thing to suffer from old or low oil.
- Check the cam adjuster solenoid and its screen for sludge.
- Only then suspect the timing chain or belt and its tensioner.
Reading the code is the easy part
A code names the circuit that complained. What tells you why is watching the sensor behind it while the engine runs — and that is where a code reader stops and a diagnostic tool starts.
VAGPULSE reads your engine ECU's fault codes and the live measuring blocks behind them, and clears the codes once you have fixed the fault. On the engine it also does what a generic OBD reader cannot on a VAG: coding, adaptations, and Stage 1–3 flashing on Bosch ME7 petrol ECUs, with a backup saved every time it reads your ECU.
