I have a 2009, 207 with 47k miles. I bought the car with misfire, I have changed, cam sensors,timing chain, dephasers and electro valves. Currently car is starting and running, but when checking parameters on diagbox, in variable valve lift menu the engine mode shows as ..downgraded with motorised butterfly.
There are no fault codes showing and engine idles at about 800rpm.
Prior to messing about today the car would idle erratically but engine mode would be normal, however electrovalves never hit the reference degrees no mater how long I left engine run.
I'm tearing my hair out, any suggestions on how I get this engine running how it should be.
