As the title suggests, the problem is at the start of the day, its my father in law's g reg 2.2 coupe quattro, and it chews on for ages before it will start.

It is starting to flatten the battery before it will start. when it is warm it is better.

he thinks the cold start valve is at fault, and has taken it out and cleaned it up, but it is just as bad.

What else would you suggest he could try, as its getting tiresome! I remember something similar happening with my old 90 years ago, but i got rid of it before it was bad enough to need sorting out.

Any advice appreciated. Cheers.
