put Lexia on briefly 2-3 weeks ago, noticed that rear LED brake lamp showing short on the live side, sure enough lamp wasn't working.
so as you do on a Bank Holiday i thought i'd take a look....finally got all trim and clips undone without breaking anything..1st for me!
not looking too promising..

managed to get lens off without breaking, however the reflector was slightly more stubborn so won't be going back on

connecting pins and wire look a little worse for wear, tester on and definitely no continuity, short wire checked and that is OK so Citroen here i come, lube at the ready
