Vanos solonoids can cause flat spots amongs other things

We had this on our mini, didn't throw any codes. It introduced a flat spot off idle which made gear changing lurchy & felt like a lean mixture.z4all wrote:would that throw up an error? do you know how i can check this? its very subtle though.Smartbear wrote:Vanos solonoids can cause flat spots amongs other things

A new solonoid didn't cure it, we had them purged and it's been fine ever since.

What does "we had them purged" mean mate?

There's an option on the diagnostics kit to purge solonoid valves, it's like bleeding brakes I think it opens the valves for a set amount of time with the engine running to purge the vanos system.z4all wrote:What does "we had them purged" mean mate?

Interesting stuff. What software / diagnostic gear would you need for kind of thing. Currently I only have Carly pro.

My 2.5si sport had a miss at 3000revs which was down to valvetronic sensor.Take the multi-plug connector on front top of rockerbox off and if you can see oil inside then the sensor seal has gone.
Search valvetronic and you will find photos of mine.
