Hello, don't recall having this issue on my S1 Aero 8. Where are you in the south of France? I live halfway between Montauban and Auch and if you're not too far away I'm quite happy to have a look for you and if necessary we can put it on the four poster. I don't have anywhere near the knowledge or expertise of Simon, but did all my own maintenance and repairs for 8 years and 40,000km so learnt my way around the car a bit.
Cheers
