I'm replacing all the driving bulbs I can with CREE's and have found that the fogs are going to take some cutting to fit and the high beams wont click in but I have made clips for that but I'm coming up blank on my cornering bulbs , no matter which way I plug them in they wont work and I get a general communication fault on them when I read the faults , any thoughts gentlemen ? 2008 MY Supercharged

Not wanting to state the obvious... but have you checked the bulb off the car, just to rule out a dud? And I wonder if they are wired up the same way that the rear fogs are... cos they follow no logic and require a box of tricks to make them work on the rear when an LED conversion is done  Yesterday I couldn't spell Engineer...

They do work because I have tried them in the fog lights , that's how I know they don't fit
The rear light conversion does not work due to different wiring but my problem must be more straight forward , the bulbs clip into the holder and simply don't work when I go round corners . Now could I have my Light Control Module somehow or even something on the light itself? 2008 MY Supercharged

So if the "going around the bend" lights work with normal incandescent bulbs, I would suggest that you add some ballast resistors to increase the load on the circuit... there might not be enough load to activate the lights.. bit like LED's on a trailer, some work perfectly.. others cause all sorts of havoc, and the difference is the amount of load that they impose on the circuit  Yesterday I couldn't spell Engineer...

Thanks for your thoughts , I didn't think of can bus problems I don't know how little resistance these CREE bulbs create



I have now ordered some error free to see how that goes

Edit; that picture is crap sorry  2008 MY Supercharged

That's a picture...... I thought it was a fancy full stop

You of all people should know how fussy the LCM can be and all the hissy fits it has when it's give LED's to monitor... seeing as a normal bulb works and an LED doesn't it can only be a lack of load that's up the system... Just think of a ffrr as a three year old.. no matter how much you try to help them, if they don't want to do it... it's a temper tantrum, dummies spat everywhere and all the toys thrown out the toy box
