my x type 2.2 diesel will not go above 2500 revs whats the problem thank you

 

To be very honest , you may also wish to join the UK Jaguar Forums site . Over 80% of the X type forums are Diesel owners & know all the tricks. This is basically a USA based site & Diesel jags were not exported to USA,,,JaguarForum.co.uk - The World's # 1 Jaguar Car Forum

 

I also have a Jaguar X-Type 2.2 Petrol but it jacks whenever it gets to 3000revs though sometimes its goes above it. what could be the problem?
