When first looking at a car that has a problem one of the easiest things to notice is any wiring modifications and if any are found they are suspect. For the most part they were done as a work-around to the original problem and now are a problem themselves. At least you found it and now the car is running as it should. That ground wire should be completely removed so no one will find it and think it should be connected again!
IMHO A PO likely took the car to a European Foreign Car shop (VOLVO,AUDI,JAG etc) where the tech was familiar with how the K-jet works and knew how to work around the problem with a Quick fix. Likely because they didn't know where to get replacement parts for the car and it was a cheap fix at the time. There aren't many DIY owners out there that would know enough about the K-Jet system to do a mod like that. This is now the second time I've seen that exact same modification. Coincidence, I think not.
