Scirocco Register

Hi guys. Me again. With ANOTHER problem now
She runs fine and drives fine if you drive her gently. But if I put my foot down and get to around 50-60 the car pulls back and the revs stop dead where they are and the car slows down not giving any power. As soon as my foot goes on the clutch the revs drop and it cuts out. Wait 30 seconds. Starts again and drives fine until I put my foot down. Does it every time.
Help please.

Tried driving with the fuel cap off as I thought there may be a vacuum. It did cut out still but with it off it really did cough and splutter before it eventually died. It seemed like it was really trying but still to no avail

Rusty fuel filler, blocked filter, etc etc

This ^^^^

Carb or injection?

It's a 1.8 8v with weber carb mate

Try blocking the fuel return too

^^^^^^^ what Nate said.

yep have had this.
will defo be crud in the jets and float chamber.
strip the carb and clean it out and get a few filters on the incomming fuel lines asap

I run a hose straight from the fuel pump to the carb, bypassing the fuel return filter and she seems to be running fine now (touch wood) I will keep it like that. Is there any issues i should be aware of now I don't have a return? Cheers guys for the continuing help!

some people say it's bad for the pump, as it will be trying to supply more fuel than the engine is using at most times, but i ran mine with the return not used for ages with no problem. worst case scenario would be premature failure of the fuel pump

Moving on to my NEXT problem. So I bypassed the fuel return and my car has been running fine ever since. BUT NOW when I have driven over 50/60 it runs lovely and smooth but when I come to slow down I put my foot on the clutch and instant death! Starts again straight away with a few flaps of the accelerator pedal but is still very temperamental then after. Either revs dropping really low or a complete cut out. Any ideas guys?

Note: usually I wouldn't be so bothered as work is a walkable distance but with only 3 weeks to go until I drive to 'men in vw' show in holland (!!!) I'm getting worried if she is up to it or not. Please restore my faith in beautiful car!

Hey dude have you managed to solve this cutting out issue? I seem to be in exactly the same boat.
