code P1525

getting code 1525, “Camshaft Position Actuator 'A' Control Open Circuit Bank 1”
the code only comes on after the car gets hot, and doesn’t seem to run any different. once it’s hot, it keeps popping up after it’s cleared.
think it’s it’s a short, or needs replacing?

Sounds like the cam position sensor is soft failing. Suggest you don't scrimp on the expense. Fit a BMW or OE sensor. The cheaper sensors tend to cause problems.

Buy the camshafts position sensor at FCPEuro. It’ll have a lifetime warranty.

I'd definitely check the wiring harness from the intake camshaft position sensor to the DME connectors, and check for fluid infiltration while you're there. Oil can wick inside the wiring all the way to the DME and short out signals.
As mentioned, replace the sensor with genuine BMW or OE quality, fcpeuro.com will have it.

Definitely check that wire. I once pinched a camshaft sensor wire beneath a thermostat housing.
