Thanks MS
Happy with all that, I ordered the 2 O-rings at £30 from VW!!
, I saved on the oil and bought the BorgWarner oil through work so at least that compensates. Once this is done it won't be done for another few years so don't want old seals letting me down at some point (my car is now 5 years old so think this is the year to crack on with going over things, like this and gearbox oil change)
1 question: if the relearn process needs to be at 20c+ to prime the pump and top up, and you are doing this in a workshop. How do you get the temp up without driving it with a low level, just run the engine for radiated heat and check on Vag-com before starting the relearn?
i.e. when filling it back up after the pump check and clean, you pour in fresh cold-ish oil into a cooled down unit, then the relearn process will be started when cold and not at 20c? and I guess you don't want to drive it as its low on oil?
