My 16v doesnt like starting from cold as well mate it takes ages ive swapped the coldstart valve and the thermotime switch but its still the same. Its fine when its warm

I've been told it could be down to the spark plugs not sparking correctly due to not getting enough power from the battery.

mine does this aswell

i think its caused by leaky injectors which drip overnight, so that when you try to start the car in the morning, its bascially flooded!

haynes details how to test your injectors

[golfvr6]

Leaky injectors will usually cause a problem with hot starting. If the cold start valve is ok then look at the warm up regulator.

[Gambit]

nah its when its cold and left for a long period of time, i.e. overnight that the injector leak is noticeable

warm starts is fine as there is not long enough period of time to cause the mini flooding.

try disconnecting the cold start valve and starting it - these leak also

You won't get a problem with flooding if you leave the car overnight.
Are you sure your problem is caused by the injectors? i doubt it is.

i know mines the injectors simply because first time you try and start it, it takes ages due to the excess fuel in cylinders once this is burned off it eventually starts.

if as soon as it catches i turn the ignition off, then start it again, it will start on the first turn.

just pull the injector out and stick it in a jamjar, start the car on 3 cylinders then turn it off, after 7 secs (i think) there should be no more fuel dripping out the injector.

If the injectors were leaking then wouldn't you flood it doing this?. Have you actually removed them and tested them?
Are you saying that your injectors drip all night?
If the injectors leaked for a while after you turned the car off then the fuel vapour would be long gone by time you started the car in the morning.
