Hi I have a 2008 Mini Cooper 1.6 The engine runs perfect until its warm and in traffic the idle then its very uneven as if its on three cylinders no codes present if i disconnect the exhaust vanos solenoid while the engine is running the idle returns to normal and the car can driven all day without issue but a little sluggish . Both vanos solenoids have been replaced with the new timing chain with pulleys coils and plugs all in the last six month due to various faults and maintenance the vanos have been adapted and I've checked the cam caps next to the pulleys for wear I've also rechecked the Chain timing with locking tools any help greatly appreciated
