Okay job done,, the guy was cool and seemed to know what he was doing.
Took him 35mins,, he took care of all of the above points,, it gave me a chance to look around the engine bay as well.
Cost wise, I was quoted between £185 and £250 but as this is my company car the leasing company picked up the bill.
Well I have just looked at the invoice and the final bill was £398,, hang on,, who is ripping off who,, thank goodness I pay my £8 per month for the maintanance contract.. wow £400 big ones for a replacement..
