I have problem with valvetronic. Code permanent

Mr.kunky · 03-06-2021, 11:02 PM

I have a problem with my car, I bought it at auction a few months ago and I still haven't been able to get it out due to a problem with the valvetronic, and I have changed the shaft three times but I put the shaft used but it was like new and I still have the same code And they told me that he gave me and I also put it on new and even the same, the car sometimes loses strength and is limited in 40 other times it accelerates well I put it in sport and it changes once to comfort and I no longer know what to do I have already spent enough money, any help or opinion, pls[IMG][/IMG]

you have to do a valvetronic relearn through ISTA after the replacement. Did you do this?

It could also be a faulty valvetronic sensor.

Call a tow truck and bring it to a shop.

We do not even know what kind of car this is.

OP, just to confirm- did you replace BMW valvetronic eccentric shaft?

Please note: special BMW tooling is required to release tension from the shaft springs and levers. So this is not a simple procedure.

If I already did everything because I work in a workshop, I do not know if it is an electrical problem, I say I do not know why I am still in the same thing or it will be to change the whole head and get out of the way

You said you changed the shaft 3 times. Did you ever replace the servomotor?
