P0365 on Audi: Causes, Symptoms and Fix Cost

Quick Answer

Safe to drive (short-term)

P0365 on a Audi means the engine computer is not getting a valid signal from camshaft position sensor "B" on bank 1, the bank that holds cylinder 1. The "B" sensor is normally the one on the exhaust camshaft. The sensor tells the computer where each camshaft is, so fuel injection timing and variable valve timing lose accuracy when it fails. The code can be set on an inline engine too, because every engine has a bank 1.

What does P0365 mean on a Audi?

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Audi models that log P0365.

Audi A6 3.2 FSI V6

2005-2011

On VW Group cars the bank 1 "B" camshaft sensor is G300 in Ross-Tech's wiki. Its P0366 entry for that sensor lists wiring, the sensor itself and mechanical timing faults (a stretched chain or belt, worn guides, a cam adjuster fault or low oil pressure) as causes. For a suspected cam adjuster on the 3.2 FSI it suggests swapping the left and right side parts, where compatible, to see whether the fault moves.

What causes P0365 on a Audi?

Beyond the generic causes listed on the main P0365 page, these are the patterns noted for Audi models:

  • Faulty G300 sensor or wiring

  • Cam adjuster, chain or guide wear on the 3.2 FSI

How to diagnose P0365 on a Audi with OBD2

  1. Read all codes and the freeze frame. Companion codes for the intake cam sensor (P0340), the crankshaft sensor or cam timing show whether the sensor itself or the timing is at fault
  2. Work out which sensor is "B" bank 1 on your engine from the workshop manual. Bank 1 is the cylinder 1 side, and "B" is normally the exhaust cam, but the layout differs by engine
  3. Inspect the connector and wiring for oil, green corrosion, bent pins and rubbed insulation near the valve cover
  4. Check the sensor's supply voltage and ground at the connector with the ignition on, using the voltage the manual specifies for that sensor type
  5. Capture the sensor signal while cranking with a scope. A missing or ragged signal points to the sensor, wiring or tone wheel
  6. Remove the sensor and look at its tip for metal debris, sludge or damage
  7. If the sensor and wiring pass, compare cam and crank timing with manufacturer-level software; a generic OBD2 reader does not show cam angles. Large error points to chain wear or a cam adjuster
