Buzzing Relay

[Dutch GT]

Hello, our 'rocco has what seems like a buzzing relay that does so after driving for a few minutes from cold. I guess it is an auto choke relay, but this is an un-educated guess. Anyone have any ideas?

I keep meaning to listen out for it with my ear close up to see if it is a relay, but as it is the mrs' car, I forget and it's already happened! It is a kind of electrical shortening crackling for maybe 2 or 3 seconds, just once.

Thanks, Paul.

I know what you mean! I had the same thing for ages, everythign worked fine though form what i coudl tell and then i scrapped the car. May just be a failing one, if you have spared keep swapping each one until it stops. Process of elimination dear watson!

What is the part number for the relay mate as I have a few spare ones?

I'm still not sure which relay is buzzing, but I will let you know if I find out.

I now have a haynes, and see there is no relay for autochoke!! My guess was way off. It does only happen once each day though. My mrs said the car cut out the other day and wouldn't restart - but she is a new driver, and gave up too soon, her friend came soon after and it started! So there might not be a problem, but it happened at a point where the buzzing would have happened. Maybe it is the one for the fuel pump, hmmm, is there any way to test each relay?

Mate, see if it is the relay with part number 171 906 383, I am sure that this is the carb intake manifold heating relay, if so I have a spare.

I think that's the same one as the fuel pump, but at work so can't check it. What would you want for the spare ?

Cheers mate.

EDIT - just read a thread where someone had similar but turned out to be a faulty carb sensor. Will look into this when I get home with a cup of tea and the haynes.
