My car (2014 V6S) went into Jaguar dealership to have the injector for cylinder 4 replaced.

They identified cylinder 4 as the misfire through engine amber warning light and fault code and identified the likely cause of the misfire as an injector failure through diagnostics.

Unfortunately they didn’t know which cylinder was which so replaced the wrong injector.

They have now had some outside help and are going to rectify the situation.

Does anyone have a diagram that shows the correct numbering of the cylinders so I can properly check the work they have done.

Thanks, JC

👍

In case you ever need it, here’s a very good F-Type write-up (with pics) on injector removal and renewal.....
