I know this is almost a year old now but when your chain jumped a few teeth did you ever have starting issues? I fear mine has gone out of timing as I have an intermittent starting problem, low power under 2500revs and can be quite jumpy under load.

I've got a gasket ready for opening it up but whilst it's open I want to really hit it on the head and sort it!

No codes either!

Sorry to resurrect an old thread but if disconnecting the maf made the rattle stop what would this mean?

Like a limp mode that disables the valvetronic? Could that mean that the valvetronic is at fault?
