Hi Stephen, I got my s type with a 3 months warranty from Stratstone, and kept a list of any small vagary from what I considered the norm, and after 9 weeks I took it back with the list, and to be fair, they sorted everything out. The only problems I have had were two rear bulb replacements and the EGR valve sticking, and to save a mucky job I have used a can of Wynnes EGR cleaner. The 2.7 Diesel is a very good engine. Regards, Peter.
