Hi peter, hadn't realised how close u are to me in Freckleton just outside Preston, u might have to let me know about your mechanic and if he is mobile or works from home as I might be needing him myself as no garage around hear will touch my car as they are not geared up for them, my mates car is still at the garage and this is week 4 and still not done, went in for glow plugs changing and 1 sheared, it's a joke. Don't know what the bill is going to be as the head had to come off, but he is putting a new timing belt on so he knows he has another 105,000 miles. My abs fault is still coming coming up from time to time but it's running fine and the garage plugged in and it's got no faults, so I'm going bald from scratching my head. I can't help u with the obd problem as I ain't got a clue what it is, I only have a full stop after my name.have a nice day, I'm off under the wife's Astra now as it's playing up, can't win.
