This bulletin applies to 2013 Jaguar XF, XJ and XK vehicles. The engine may run rough with symptom 608000.
A new VCT solenoid has been fitted to a 3.0L AJ126 or 5.0L AJ133 engine which requires a link harness in order to be installed on vehicles built with the prior part. The VCT solenoid design changed and the electrical connector on the VFT solenoid is a different size.
A link harness is available, P/N C2D40548, to join the existing harness to the new VCT solenoid connector. If the VCT solenoid to be replaced looks like part “A” in the accompanying photo, then a link harness is not needed. If the part to be replaced looks lie part “B” in the photo, you will need the link harness.
