Car Forum / Volkswagen / Water Cooled Volkswagen Cars / August 2006MK1 Cabrio cutting out
Anyone had problems with there 1.8 Cabrio cutting out? suspect fuel problem, runs fine then for no reason cuts out- sit for a minute then re-starts. It will run for indefinate periods then the same happens again. Filter has been changed, carb stripped & serviced, could it be rust or particles from the tank. Any ideas or thoughts appreciated. > Anyone had problems with there 1.8 Cabrio cutting out? suspect fuel > problem, runs fine then for no reason cuts out- sit for a minute then > re-starts.

The classic Mk1/Scirocco problem is rust in the tank. What state is the filler neck in the wheelarch in? > > Anyone had problems with there 1.8 Cabrio cutting out? suspect fuel > > problem, runs fine then for no reason cuts out- sit for a minute then [quoted text clipped - 4 lines] > The classic Mk1/Scirocco problem is rust in the tank. What state is the > filler neck in the wheelarch in? At present I'm not sure, I had the car into my local VW garage who fitted a new petrol pump, stripped & cleaned the carb, but this did not solve the problem. It was the garage that informed me it may be rust in the tank? next step, they are going to fit a new float & main jet? I'm just thinking of the £££££'s. It may be partly my own doing? I only use the car 6 months of the year & of course with car sitting in my garage the tank sits nearly empty. 500miles in the past year so it's very little used. I'm just hoping for a quick fix. Thanks for your reply >> The classic Mk1/Scirocco problem is rust in the tank. What state is the >> filler neck in the wheelarch in?

Thay may be blocked, but they should clear out with compressed air/carb cleaner- and they should try to clear them first. The thing to do is fit a new inline fuel filter to catch any crud before it blocks the carb again. It's possible the fuel lines or the pick-up in the tank are blocked too- as the fuel is used, the crud blocks the holes in the pick-up, then drops clear again. This seems likely, since cleaning the carb once didn't cure it. When the car stalls, is there still fuel visible in the inline filter under the bonnet? Does it only cut out idling, or will it lose power if you're acclerating too? > It may be partly my own doing?

Running the tank low won't help, but rust in the tank seems unavoidable on Mk1/Scirocco after a certain age. > >> The classic Mk1/Scirocco problem is rust in the tank.

There appears to be fuel in the filter, sit for a minute & it will start again & run for a few miles before it happens again. It did appear better a few weeks ago after changing the in-line fuel filter, but has gradually became worse, hence I put it into my VW garage. At present no resolve. > > >> The classic Mk1/Scirocco problem is rust in the tank. What state is the > > >> filler neck in the wheelarch in?

Perhaps it's clogging intermittently? The fuel flow causing crud to jam the filter, whereas it can flow through when the engine's stopped and the pump's not pumping? Perhaps try running it with a petrol feed directly to the carb from a petrol can? > Perhaps it's clogging intermittently?

The filters & tank pick up can clog intermittently, causing the symptoms described. > > Perhaps it's clogging intermittently?

I will update with the outcome as and when? The carb has a return hose to the tank, so don't expect it to go far if you don't return to the can! VW sent journalists out (in Polos I think, back in the mid '70s) with a gallon of petrol in a can to see how far they could get. They all started phoning in after about 5 to 10 miles as the fuel was returning to the tank! Doh!  SignatureDave.

Don't know about this golf, but many of them had a resevoir bolted to the cam cover- the fuel feed and return pipes went there, and the carb picked up from it. If you took the pipe to the carb there, you'd be OK. If you gravity fed it, the excess would still return to the tank. If you connected it before the pump, it might feed both ways! Talking about the reservoir, if it has one, that can be a source of problems, I've heard. SignatureDave.

I wondered if you could take the pipe off between the resevoir & carb, and feed into the carb that way. To be honest, I can't remember 100% how the pipes run. Yes, that should work - sorry - not thinking clearly enough! You'd need to stop the reservoir outlet or it would gush nicely into the engine area! SignatureDave.
