I really feel your pain. I have had my fair share of problems with a warranty claim working out at once a month for the last 6 months!
Last time it went in for a new clutch and flywheel. The car is only 1year 10months old.
Anyway, I have had it with this car and so has the lease company. It will be gone in the new year.
I will do a thread about this another day.
Good luck with this mate. I will keep my fingers crossed for you.
