All fixed now: Took an eternity, though. Spring had arrived yesterday so the car was up on the hoist at 08.15 for a one hour job.
I phoned at 12.30 and they said it would be another hour and a half: They had been sent the wrong spring and another had to be acquired from the Distribution Hub in Leeds (50 miles away).
Got to garage at 14.00 and of course (as I anticipated) they'd destroyed the drop-link in removing it, so I had to wait another half hour for that to arrive and be fitted.
But, they only charged the quoted labour at £35, so all in all it was £120 notes. I did mention that the parts were just so much cheaper on eBay, but could not fully comprehend the swearing noises from behing the counter!
And they can do me a Cam Belt Kit, fitted, for £120 too, which is somewhat cheaper than Main Dealer prices.
So I'll get that done soon.
