After much confusion and worrying, I finally got my P reg GTV 2.0 TS started and found out what the scary rattling was. Did my 4 months away from home after the immobiliser was tripped and didn't start and simply connected the battery back up and it started first time!!! ( I don't have a master key ). It's running fine now. And as for the rattling coming from my driver's side wheel well, found it to be the rear bush on the bottom arm has snapped which was causing play with the steering. Put it through it's MOT and it needs new rear brake disks and pads, exhaust centre mount, new bottom arm bush, new CV gaiter, side light, two near side tyres and it even failed for having a smelly tree dangling from the mirror!!! It is costing me £388 inc. parts, labour and VAT. Looking forward to getting back home for good in October and getting my baby back on the road and joining the rest of my fellow alfa owners out on the flooded roads of sunny England!
