Dave recently had a leather cowl fitted at Allon Whites when they had finished the car would not start so they had to dissemble the cowl and alter it since then it has refused to start twice but taking the key out and putting it back or changing to a second key starts the car. I now always take two keys with me! As you say it is disconcerting when this happens! Had the same problem with my 4/4 a few years ago Allon white also described the 20 sec rule! They also said jiggling behind the cowl with your finger sometimes works ! ! These pics above are very helpful thank you!
