Hi Magnet,
Many thanks for your response. Truly appreciatable. The car cost me £300,done 120k, 2 owners and has a good service history.
Engine, gearbox and clutch seem good.
I've taken it on board as a bit of a project and to learn motor mechanics, now I'm retired. Not owned an Audi before and am impressed with the level of quality.
Have replaced the rear discs, pads and carriage spindles. Had a problem with the rear o/s wheel overheating, now sorted. Changed and flushed out the engine coolant. But those two items have to be done on any car at some time. Myself I think the a/c is worth repairing for quite a few reasons. Primarily I like it when everything works.
No doubt I'll be on this forum again.
Yet again, many thanks for your response.
Kind regards, Tony
