Sod's law really, but I am feeling a little better this evening thankfully. Not a moment too soon as it turns out though, since the 206 has developed a brake fluid leak recently which I'm guessing is a failed wheel cylinder and just a couple of hours ago Black's drive belt tensioner decided to seize solid creating a nice smoke-show from under the bonnet!
Fortunately this happened after we arrived home & I was just shifting cars around (Once again the good ol' Xantia hangs in there to get us home before failing, just like the other FTP when the inertia switch popped on the way home from MoT! Loyal car

) and I have a spare tensioner and belt in the garage too.
Gave me a fair fright though, first I knew was it cranked over a bit slow like the battery was down even though I knew it wasn't, then I smelled something warm and then started to see thick smoke billowing from under the bonnet... Thoughts of melted/shorting battery leads and a battery ready to explode were at the front of my mind as I popped the bonnet, there was even smoke in between the bonnet and it's sound deadening material... I can honestly say I was about as pleased to see a wasted drive belt as I could ever be, even if it is a shame it's a lot easier/quicker job to replace it & the manual tensioner than it would be to replace any chunks of wiring loom...
As I said, sod's law that it all happens at once but we shall overcome

Fingers crossed it's not tipping it down in the morning as I'll have to fix Black then, the bearing collapsed and freed off a bit when it cooled so I ought to be able to get the suspension on high at least.
