Car: BMW Z4 35is
Default Z4 35is - Vanos Code 2A82 - 10-05-2020, 02:03 AM


I have a Z4 35is. I'm getting an intermittent Intake Vanos code 2A82 with half engine light and the car is much slower.

If I drive in normal mode from cold then I get the error when the oil temp gets to about 140F. if I drive in Sport mode and the oil temp is about 230F then I can drive all day with no error.

I have replaced the Vanos Solenoids, Vanos filters and oil filter cap. Bmw say that it may be worn Cam tray ledges and they have to strip to inspect and huge cost. The car only has 44k miles and has been maintained and serviced regularly.

is it possible that cam trays could be worn after such low mileage? The car was modded before(FBO, JB4, MHD, Hybrid turbos, meth kit) but is now completely stock with latest software upgrade at BMW.

Please help? What else can cause this Vanos error? How can test to confirm that the Intake Vanos Unit is OK? Ive removed the valve cover and the engine is clean with no loose bolts on the Vanos units.
