Anyone send me a link to the right one please?

Thanks

There is only one, relay No. 21
VW fitted it to evrything, a used one is about 10p

Hmmm, mine looks nothing like that. Maybe it's a random motor factors version.
I'll check the pinout tomorrow to be certain.

Thanks for the help.

Fairly sure its a tall 4-pin relay Kev although I'd need to check. I have a similar issue as I want to change it for one that can cope with LEDs.

[chewbacca]

Just had a thought, I've a towbar warning light on the dash. I wonder if that's why my relay is different.
Guess I need to investigate & report back.

I doubt a tow bar would make any difference...mine doesn't

Standard indicator relays use three pins marked 49, 49a and 31
Vehicles with a towbar use a 4 pin relay. 49, 49a, 31 and C2. C2 goes to the trailer warning light on the dash.

What's the purpose of the warning light?
Never really understood that.

[nicq]

If wired correctly it only flashes with the indicators when a trailer is connected. It is to show that the trailer is connected.

[bigherb]

The warning light tells you the trailer indicators are working, as it is a legal requirement to have some form of bulb failure indication for front and rear indicators.

[chewbacca]

Gotcha.
Thanks guys. I'll investigate further when next on wiring.

Watching this thread with interest, my relay same as chewie's has failed, they are available from Gunzl but they are 25 Euros plus postage https://sage-shop.com/epages/GuenzlClas ... ID=1175778
would love to find a used one

But a standard one (21) works as a substitute - just wont light up the light on the dash when hooked up to trailer

I've not had chance to look yet to be honest.
Been busy with other jobs.
It's on the list though.
