So, the first issue popped up on the holiday - A strange knocking sound on the front right corner over bumps. I stopped several times and wobbled things and climbed under the car, couldn't find anything - I drove on for some time, stoping and checking stuff until I found a place where I could jack the car up and properly check. Suddenly!

Sadly my tool kit did not have the correct sized socket ... And it was 1900 in a small town in the south of France, I tightened it as best as I could by hand and carried on. I managed to nurse the car the remaining 50km to our accommodation by riding the brakes over bumpy roads, I stopped every 10km and checked to see if it had come out completely or any more - But it was stable enough, so we made it.
This morning we drove to the nearest supermarket and bought a reasonably cheap tool-kit that would do the job. Obviously I could have found someone to tighten it or borrowed some tools but I figured I should have the right tools in case it happens again:
Anyway, here is a compilation of pictures:
And after that, the noise was gone and I have a toolkit!
We are nearly at 2,000km on the trip so far and this has been the only problem. I look forward to the next 2 to 3 thousand kms!
