Hi all, first post here.

We have a 2015 Macan S diesel that has had intermittent front indicator issues. They started last year around summer and only occurred on the really hot days - what would happen is that they would stop working someway into a journey: we'd get notifications on the instrument panel such as - check front left indicator bulb, check from right indicator bulb, check from right parking light etc. Sometimes both left and right would pack up, sometimes just one of them. And then at some point they'd start to work again!

After the summer and through to this week - no issues whatsoever. But just over the last few days it's come back - but this time the difference is it's not hot (I won't moan about the British weather)!

We took it to a Porsche specialist last summer and they couldn't find a fault anywhere and we were left with their only recommendation to change the PCB/management system (can't quite remember what it was actually called) associated with the front lights/indicators.

One thing we haven't done is to replace both of the front indicator LEDs - which I'm now wondering if that's worth doing as a process of elimination (but I think, might be wrong, the specialist said that wouldn't help in this situation).

So - over to you clever people to see if you have ay ideas or similar experiences.

Many thanks, Gaz.

I had similar problems with a 2019 Macan a couple of years ago - but affecting the rear indicators. . It turned out to be water in the light units - replaced under warranty

Thanks - I'd like to think that the specialist would have noticed that but we did at the time think that it might be water/humidity related. Our car is well out of warranty.... Was it water in the indicator units or water generally in the main headlight unit? Thanks.

Harveyg mentioned rear indicators, so headlights probably not involved?

No - the entire light bar (that is part of the bootlid) was replaced. Cost £900 plus labour ! As I said though - replaced under warranty (one month before it ran out !!).

Front indicators are sealed units. Whole unit has to be replaced, No separate LED unit.
