Problem when tank less than 1/4 full
I have a problem when my fuel tank is less than a quarter full (usually around the 280 mile mark!)
If I try to boot it off a roundabout / accelerate out of corner I suddenly get a judder and there's nothing there powerwise until I change up or down a gear….
It is usually when I'm in 3rd gear and have been turning right (duh - that's the way you go round roundabouts right

Has anyone else had this? :dontknow:
My dad reckons it could be due to one of the fuel pumps that keeps a resevoir of fuel for just such occasions…
Any thoughts appreciated!
Cheers

As the fuel drops in the tank the amount of lift the pump has to do is greater. A weak pump will then struggle.
Budget ?35 for the pump - make sure the new one comes with a strainer.
Lift pump is accessed under the rear seat by taking out the level sender.

I had a similar problem that was fixed by fitting a new bosch pump (the one outside the tank.) It got knackered after running low on fuel. Could tell it was knackered by the amount of buzzing noise it was making. I assume yours has a GTi engine (k-jetronic fuel system.)? Otherwise this will be meaningless to you!
A damaged lift pump sounds a lot like a noisy main pump. And a new main pump is likely to be able to draw fuel better - my money is still on the lift pump

youll hear the outside fuel pump from outside the car better.
if your main (outside) pump was knackered youd hear it for sure!
and youd have problems tank full or empty.

There is a loud buzzing to be heard outside the car door (rear driver's side - the pump is accessed on this side of the car under the rear bench I think?) so think its def the lift pump….
New one on 'THE LIST' which grows longer faster than I cross things off
