Not an Audi (obviously) but seems to be a lot of good knowledge on here so thought it's worth a shot.

We've got a MK3 diesel golf and in the last month or so been having trouble starting it. Really have to give it some beans to get it going, otherwise it stutters and cuts out. Once it gets going its really smooth and reasonably quiet. It's only really used for short journeys on a day to day basis with longer journeys at 50-60mph over the weekends, about an hour long 5 or 6 times.

We treated a tank of fuel to some fuel cleaner, but no change on the following tanks, still doesn't like starting from cold. It was a cheap cleaner so plan to try a better product, redex or slick50 maybe. We've had the glow plugs checked and they were fine. They said to turn the key and when the coil goes out turn it off and on again a couple of times, just to let them really heat up before trying to start, but no change.

With how well it does run, fingers crossed it's nothing serious. Here's hoping. I'm going to take it for a good blast up the motorway at the weekend to see how it goes.

So, is there anything else I should be looking at?

Cheers

Is it possible the battery is the issue? Just not quite getting enough charge to start it unless you give it some throttle.
 
Is the battery ok on the car??

I would say thats your first port of call, considering it doesnt get driven much and not having adequate time to charge, its probably just draining away and even more so with the strain of starting the car up.

If you have a multimeter, get that on there, i believe it should show about 12v when the car is off and about 14.5v when its on, check that first then go from there.
 
Its driven everyday, just not very far.

The battery seems fine, but will check it over.
 
I would still check that for a start and then move on from there.
 
Seems to have good charge. Glow plugs next. Why does hitting the throttle start it? Surely that's just giving it more fuel.
