Hey guys,

My n54 is throwing the 2A99 code.
I already changed the exhaust vanos solenoid(aftermarket) and switched the sensors (intake and exhaust but the code Keeps coming.

Has anyone an Idea?

Car is an '09 e90 with 63k miles on it.

Dont know what else to do :/

My old 325i had a similar issue i think. Ended up being the non return valves in the side of the block. Took em out and they were totally blocked with crap. Cleaned them up and never had a problem again.

Hope this helps, I'm new here haha
