I have a 2005 Cayenne that the turn signal warning to check bulbs come on the left turn signal.....have checked all bulbs and they all light! Any ideas out there?

Do some searching and you should find a few threads. It's probably a loose connector or loose headlight bracket. It could be a corroded connector.

Thanks...have tightened all...but looks like it should be a bad connections....but why do blubs light and still get error??? Thought that it might be the circuit board in the light...have not switched to check that out....most on thread have problem with the right light...mine is the left

Very likely a bad headlight connector, search for the wiring mod, Fixed mine.

Remove the headlights and check the headlight bracket. I'll bet it's loose. There are two 10mm bolts on the front of each bracket that loosen up over time.
