Things to look out for
.Chassis ( especially at the rear)
.Leaking Sunroof
.Ace pipes ( these can leak and can be costly)
.Fuel pressure regulator
I'm sure there is lots I've missed but if you do a search there is loads on what to look out for.
I've been pricing some mtf94 gearbox oil up, I've got two Td5's to do and a 300 tdi the cheapest I've found is Smith and Alan which is about 45 pound for 10 litres, has anyone used this or is their another brand I should be looking at.
This reminds me of when I was parked in town with the engine running to keep warm when all of a sudden this bloke told to me to switch the Disco off the cheeky fecker
You can get them on eBay, if you put your location their might be someone near you who has one, You could go to a dealer but I'm not sure what that would set you back.
