Or Directional Indicators if I have Jaguar's phraseology correct.

Couldn't find a helpful post & mechanic who apparently didn't know what he was doing took apart my under dash.

My left side indicators all failed at once (front, side & rear). Checked all the fuses relating to turn signals and checked and/or test swapped out bulbs. NOTHING!

Mechanic was told (and sold) a FLASHER MODULE to fix it but all posts here indicate controlled by BPM.

After driving other night, instrument lights wouldn't dim off. Had very frustrating time pulling fuses to shut off. (Sure it has something to do with mechanic's disassembly of dash/steering column.) however in my search for THAT solution found a fuse blown for LH DI repeater; lo & behold I have turn signals again.

Funny that this isn't clearly pointed out in the Owner's (Or even Jaguar's) Service Manual !

Even other posts dealing with X300 DI problems don't mention this. So pay attention all, sometimes the simplest solutions are within our grasp!
Sure beats interpreting wiring diagrams & frequent multi meter testing, testing & retesting.

 

Yep.

In all my years with these beasts I have found on many occasions the unknown/unwriten item is the culprit. Best of all, you know that next time, but in my case next time is still not here.

Hidden fuses, inline fuses, whatever, that never appear on any diagram, or handbook, are common from the mighty MK7 up to my current 2 S Types.
