its also possible its the relay as well then will keep you posted, would the indicators not work though when the hazard button is pushed? :Confused:

Different components powering the same circuits.

Thanks andrew does the relay have number on it? or part number? :Confused:

Unfortunately I don't know where the relay(s) are, probably in the passenger footwell panel though.
I don't even know if the flashers and indicators use separate relays or there's a combined unit. :o

I think the way most such systems work is by closing the circuit on the "earth" side; the bulbs will have a common +12V supply (fused) but are then earthed by the relevant relay(s) to light them up.

Some relevant information here but for US models, there's probably better stuff that others will know: https://forums.quattroworld.com/a8/threads/3006.phtml

I just had a look in my Bentley manual and can only see one flasher relay, it's on a panel in the cabin, presumably somewhere under the front passengers feet.

Problem is the Bentley manual only shows the rather different USA (LHD) layout.....

As I recall the relay was 'above' the passenger's feet and behind the glovebox, so 'reasonably' accessible.

Not specific, but may help narrow things down: https://www.quora.com/Why-do-my-haza...y-turn-signals
With the symptoms you describe (and assuming there's a single common flasher relay) I'd probably investigate in the sequence fuse, hazards switch, wiring....

Don’t thank me +++

This was the first clue as to an underlying cause.

And this is a possible effect: Though the fact that the emergency flashers still work suggest that may not be the whole story. Is the indicator stalk function separately fused?

So the carpets need to come up and the cover off the panel and everything dried out.

i will keep this thread updated +++

Car is going in for its mot tomorrow, garage has lined up a few jobs so will get them to investigate further, hopefully the hazard switch will turn up so that can also be tested if its not a relay! i had a good look in the passenger side fuse box sunday under the wood all looks dry in there be it a bit damp on the floor so dried it out as best i could, bit hard to see when it keeps raining all the time, took me ages to get the wood back on and lined up again :ROFL:
