Dear all,

My Jag X Type diesel 2.2 year 2008 get problem that vehicle start running ok as the engine is cool. After engine get warm the vehicle run sluggish, steering wheel get heavier, then the sound "ket ket ket" like metal crash can be heard when accelerator was pushed. I bring vehicle to mechanist but he could not detect problem. Do you have any experiences please share

Thank for your reading  

Does the engine light come on? If it does you need to 'interrogate' the OBD system. You can do it yourself with the right equipment or go to most garages who will be able do it for you. This will detect virtually all common problems and most less common ones.

If you already have a smart Android phone you can get a Bluetooth OBDII scanner for the same price, or less, than a professional will charge for one scan. Then you can do as many as you want for the single outlay.

How much better their equipment may be I couldn't say.
