Hello mate amazing video. I need to strip one tomorrow and you gave me an idea what needs to be done... on mine the fault is vvt function at stop. Only 4.7 vaults to the motor and not responding when sending the command with the tester. The sensor is covered in oil so I suspect is that but will replace both since I am there. What was the fault on yours ? Thank you

Hi, it was a mix of: 2851 DME Valvetronic servomotor, actuation 28B4 DME: Valvetronic servomotor, sluggish movement 2863 DME: Valvetronic, power limitation and had been happening over a few months. Clearing the codes helped for a while, and after changing the motor and sensor It is now running really well. Good luck with your car, let me know how you go.

Howz it?! Great video thanks man. Recently got a couple of faults show us as well namely 2A59 Valvetronic Eccentric shaft sensor 2A5B Valvetronic Eccentric Shaft sensor 2A6B Valvetronic Power limitation, servomotor. Will I need to change both motor and sensor as in your video? Or just change the eccentric sensor only Thanks mate

If I was you, I would definitely change both while your in there; the parts are not so expensive, compared to the labour or effort of changing them

Ive a question, what are all the tork specs you talking about? Like the motor itself, the sensor and what is hand fast with the screws from the lid?

[@jackpwc01]

Hi - I didn't have the torque values, so I just tighten them based on experience. if it is metal to metal you are pretty safe with it feeling tight, and around half the torque for metal to plastic.

[@freman007]

I have that too.

[@rogervillamarin6850]

Where you recommend to buy the parts? Are you in United States? I have same problem but my BMW is automatic and 4 cylinders. Can not find parts for it.

[@jackpwc01]

Mine is an Auto too. I'm in Australia and I get most parts on eBay.

[@jamiebrown2345]

Hi mate is there any programming needed when changing this or is it just plug and play

[@jamiebrown2345]

The code I’m getting is.. Valvetronic,plausibility: Sporadic Current Fluctuations

[@jackpwc01]

Plug and Play for me

[@jamiebrown2345]

@@jackpwc01 cheers mate I heard the need ‘re-learning’ as they need to learn the end stops so was unsure

[@WayToManyAssassins]

Is it normal for this fault to cause rough running/vibration especially when accelerating?

[@brandin8r550]

Depending on how busted the Valvetronic Actuator is. If it's just the motor your idle will fluctuate and your car will go in limp mode. If it's the rail that's grinded down you will get a grinding sound just as you accelerate.

[@jackpwc01]

Yes, this one was throwing the warning light up and refusing to accelerate. A restart would fix it temporarily
