Im very sure the vanos solenoids are cooked. Also theres a DISA thats also faulty.

The vanos is whats causing the biggest problems.
The disa fault will just have a code and affect performance slightly.

Someone rebuilding a 525I mentioned the DISA also. This sounds like a rabbit hole. I see they are not that expensive to replace but can it be cleaned?

Now that you mentioned that, the though will always be there "performance is slightly affected" Skit

It's not a rabbit hole. These are solid motors.

Start with the vanos solenoids. Maybe try swapping solenoids with a friend that has a 323/25/30 (same solenoids), if the cost risk is too much to bear.

DISA flaps from dealers are very expensive. Close to 6k. They cannot be cleaned. Tackle that after the Vanos.

The solonoids are getting replaced today. Dont think i ever experience my car performing like it should so i wont notice if the DISA valve is giving issues, what is the error related to the DISA valve that i can look out for?

Sometimes the disa flap guide wears out, so it just flaps around as you accelerate. Its audible and can be felt on acceleration.
Code wise its the 2AA8

Thanks for the awesome info!
