Hello ,
I have a 318i , and some time ... at 1-2 months , my check engine lights is turn on , and i got this error :

002A70 - Valvetronic, plausability: sporadic current fluctuations
002CF8- Throttle valve potentiometer
002D07-Throttle valve potentiometer
002A83-Vanos intake

I must mention that they are always the same error. I pulled the wires and nothing happened, I measured the valvetronic engine and it is good . Something to change or start with... ? Please

[edgaryo]

nobody have a ideea ?

I think a lot of people just don't know enough about the differences in the 318 to intelligently comment. Also doesn't help that you posted in DIY versus a section where people frequent like General more often.
It would help too, if you provided any symptoms you are seeing besides the check engine light.

Things to consider based purely on your codes:
- Pull connection to MAF/IAT and see if it runs ok. Tho if you're on IAT (probably) then its more map based anyway...so less chance that it helps. Also clean your intake filter and check for leaks.
- Ecentric Shaft Sensor - see if there is oil in there by pulling the hose towards the front of the valve cover and looking into the sensor prongs for collected oil
- Valvetronic actuator or CPS. Can try relearning. CPS could need replacing.
- Vanos valves (two of them) in front of the engine...check for debris; clean off with brake cleaner and dry.

Again, I don't know enough about the 318 to really speak fully intelligently about it, but those might be places to start.

Thank you !
318i is N46 , is like 320i with less power , only 129 cp .
When check engine light is on , only symtom is i dont have good acceleration . Is powerless .
- i have check filters , valvetronic actuator ( and is good , no short circuit), no leaks.
- there is no oil in the socket (at excentric shaft sensor )
- i will clean the vanos valve .

What is CPS ?

Ok so it was an E46 - forget what I said as some of that doesn't apply with an E46; . Your title had me believing it was some sort of odd Romanian E90 variant.

I'd suggest you go over to Bimmerfest or E46fanatics as they would be able to assist you better with that platform.

Is not E46 , the engine is N46B20. I have E90 , my car is from 2006.
