Hi everyone, Have same issue already within 2 month "Fault code P25A9-00. Piston Oil jets cooling solenoid" Jaguar XE 2.0 Diesel 2016 Before engine was shacking with idle speed - problem was found and fixed with engine cushion and exhaust gas soot filter (DPF) along with the damper. To fix the P25A9-00 have to find the above solenoid which is not available on stock. Have no idea why. May be someone give me advice where I have to find it? Thanks, appreciate any offer. Nikolajs, Latvia,Riga.
