Hi, got a Mini One, having emissions issue (failing MOT), been through a lot, (new valve stems, oxygen sensors & solenoid actuators but still got codes, (latest one is 288D but have had P0015, P0014, P0366 and pending including 283D). ODB plug and iPhone app.
I think it's pointing at Vanos / timing chain.
Is this something you could look at and could I get (rough) price and time it would take?
Thanks, Austin
