Hi everybody. New to the site and wondering if anyone has any input. I have a 1988 100CD Avant wagon (second owner and had it since 2012, first owner was a Volkswagen dealer principal). It is in amazingly original and excellent condition (every panel still wears the original factory-applied paint). Recently, it became difficult to start (it will start after six to eight attempts, and then runs perfectly). I suspect it's an issue with the cold start valve which the workshop manual suggests "is not a user repairable item" and, of course, new replacements are not available. It's in with my repairer (a Euro specialist) but I haven't heard from him for a week, so it doesn't bode well. The car is way too good to despatch, especially for such a comparatively minor problem, so I'm hoping someone can give me suggestions. I've attached a couple of photos of the car, FYI.
