This module has stopped talking on the car's data network, so nothing else can hear it.
Can you drive it? The engine light will stay on and the car may run in a reduced-power mode. Read the freeze-frame data to see the conditions the fault was logged under.
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 every module in a VW, Audi, Skoda or SEAT — not just the engine — shows the live measuring blocks behind this fault, gives you the freeze-frame conditions it was logged under, and clears it once you have fixed it. It also does what a generic OBD reader cannot on a VAG: service resets, coding, adaptations, and Stage 1–3 flashing with your original file saved first.
