As RocketRossUK advised, the work on mine has started. Good news until Ben rang to say we found some other issues, not only did the chain, tensioner and various guides need replacement, but one of the bearings had collapsed for one of the camshafts !!!!
. But no problem VW would pick up the bill
. Pic below (hope it works !!!!!) of the wear by the failed bearing. Had it seized then the damage would have been a lot worse. Glad I got it sorted now.
