Well....
Yesterday, we finally got the van in the garage.
Very quickly, this was spotted as the fault
Thats the gearbox oil cooler!
Our guess is that this was done during the flywheel replacement that was carried out recently.
The dealer I bought the van from, has, in fairness, been very good throughout. Answering emails promptly and politely. Isent them the Pic above and they asked for an estimate. I sent one (£456) and was very swiftly told to go ahead and get it done.
Tyremarks (the garage) managed to squeeze it in today, replaced the oil cooler and threw a new map on it while they wet there.
So now I have a van that doesn't leak coolant, does have 180hp (up from 147) and an extra 100 torques. It definitely does still have an egr valve too.
Little bro came through today and repaid some £ I'd lent him for his venture, so I'll be ordering a heater and the swivel seat bases immenently.
While in the tyre workshop, I also put the brand new Michelin from the spare (2019 tyre) to join the part worn on the rear axle. At least now, one of the 3 cheap nasty tyres is the spare, though I still have shit front tyres

.
I might change them, but they are brand new shit tyres, and it's not like it's a vehicle that's supposed to handle.....?!??
