Hi there Michael, and welcome to the Owner's Forum. I am sure you will find it a useful source of ideas, help and advice when you need it. In the nicest possible way I hope you are enjoying running your new-to-you GSI (..In my humble opinion, a very underestimated Zafira that is great fun to drive...) and that you don't get landed with problems which would mean that we see many, if any, urgent 'help-type' posts from you in the near future..!! Happy Motoring..!!
Incidentally, if you have any queries about anything Zafira related, you can always type a question into the 'search' box at the top of the page and see what other members have had to say on the subject in the past - that can sometimes be very useful to solve well-known niggles. Welcome aboard. Cheers... Robin
