Theres not much to report on the Vsx front at the moment.
The poor cars been sat outside minus its headliner for the last few weeks. I found when replacing the sunroof motor that the mechanism was truly jammed and needed replacing itself.
In removing the headliner I noticed a few other things that have really put me off doing any further work to the car. Firstly the braces that give the roof it's stiffness have held condensation over the years and there is rust between the roof and the braces. Secondly the seatbelt mountings and hangers are looking past their best, they are fatigued and old. Finally theres been a fair bit of electrical overheating going on which is sure to cause problems in the future if not tended to.
I'm yet to make a decision about what to do but I no longer feel like the extortionate cost of tax and insurance for this car are worthwhile. My gut feeling is store it and fix the problems one at a time as I'm able, the price of running a Xantia has been silly for me so I may move it on rather than let it sit unused and call it a day with Xantias. I actually called it a day with Xants many years ago because I thought they were getting hard to keep on the road, these most recent 2 were a welcome surprise but the expense and difficulty in keeping them on the road has been a real pita and I honestly haven't enjoyed them like when they were 10 years younger.
As for the Scenic I'm still really enjoying it. Our time together is due to end shortly but it's been a nice experience to drive a fairly modern car for comparison. It's not 100% healthy at the moment unfortunately. When I showed Dad what was wrong he basically said well its over 80k maybe it's time to get rid. In which case I'll definitely be the new owner even if the engine isn't quite the one I'd choose.
Faults with the Scenic include: cutting out when started from cold, an oil leak from the rocker gasket, air in brakes, missing engine cover, lost power and it's wobbly turning left like theres a worn suspension bush. Nothing too bad really, the cutting out could be the dephaser pulley but that was replaced not long ago and is under warranty. I'm hoping I get approved to spend an afternoon sorting it out, I don't see the point taking it back to a garage who did poor work to get them to improve it, they've set their standards and pinched the engine cover.
Just checked who serviced it, Renault main dealer.

Shame because I found Dad a really good independent after the last Renault main dealer fiasco. What actually happened that time was it went in for a fan belt and they quoted £850 for a new alternator and refused to give the car back until the alternator was fitted because it was dangerous. Wouldn't let me near the car to check it either so Dad sent an Rac inspector who said they were telling porkies. Different Renault garage but same old service levels.
