So today i set out to do a service.
Took the ramps off the rear wheels, put them at the front and drove it up.
To do this i had to swap the battery as it was flat after 2-3weeks no use, so swapped for a 62ah one i have kicking around and then once it had a few seconds to settle at tickover i put the other battery back on

The aux belt squeak has now gone and im guessing being sat up for so long hadn't helped that and my regular start ups are easing it off.
While the car warmed up i removed the accelerator kick back damper, and then swapped out the air filter.
Once the fans had kicked in and kicked out i switch the engine off and removed the plug and left the oil to drain.
I had the old boot base material so while the oil seeped out i set to do the fuel and oil filter.
Fuel filter done by cracking open the drain feed and draining a little out but still some leaked over the side.
Swapped it out and fitted the new one and tightened all back up, then set to the oil filter which was super tight.
So some fighting and it was off. Cleaned off the interface and then applied oil to the new ones rubber seal and fitted it.
Took the oil filler cap and dipstick out and gave them a clean with my clean oil rag.-
Even using a cut off bottle there was still some splurts from the bubbles coming back up so once the filler cover was back on and dipstick in i gave the area a good squirt with fairy liquid/warm water mix and gave it a minute to soak before then cranking the engine over and letting it idle before then using the gentle spray on the car wash hose to wash it all off and leave a much cleaner area than it was before i started.
Will double check oil level tomorrow but will pop over to oldham and pickup some total LHM about 3-4litres which works out at £1/litre which is cracking value!
Then gave the car a quick wash and did the same with the XM and maybe get time to service the XM tomorrow.
The bits i now need for the Xantia are
Drivers side wiper arm with splines intact!
Drivers side window switch pod with mirror controls.
For the XM i now need
LED refurb kit
Drivers side window switch panel(single touch down is intermittant)
MK2 radio with working lights, code and display and tape player cover (for when i sell it on as i want to stay original upon sale and the current one has a broken cover for the tape player, and the lights dont work on it

Work on air direction issue as it doesnt vary when i turn the temp and fan power as well as recirc work fine annoyingly!
On other good news, after washing the car i could see the difference in the section of the bonnet i used the meguirs restoration kit on and the rest that i didnt so another job to finish off as it doesnt half bring that part of the bodywork up and will help with a sale when people see the car in real life as it literally just shines and feels so smooth!
Order will be, Wash, Claybar, Light wash, meguirs compound, light wash and claybar again, then final polish applied and buffed off

Well thats it so far!
The XM has hit 196k and just carries on going. I keep putting veg in with 4 litres of normal dino diesel per tank. The xantia is running on pure veg now with a tiny small amount of engine oil in it as i've found about 100ml per tank gets rid of the smell of the veg quite well. The XM is also getting this treatment with old engine oil but does dilute it more than the xantia due to the size of the tank.
Getting about 750+miles from each XM tank at the moment which is annoying but with work being so varied at the moment i dont spend a whole lot of time sat at motorway speeds. Not having AC sucks in the winter but it doesnt take long for the windows to clear.
