Vauxhall customer services have told me there is no recall for the 2.2 Astra. I rang the dealer where the car was first serviced as i have no documents from this service, he checked the histoy of my car and its had no work done to the chain, he also said there was a never a recall for Astras only the Corsas! So mine hasnt been done and it has the cut out on that bolt thingy.
