The engine has had oil changes before they're due. I never thrash from cold. I bought new so i had the history. Never abused.
Crankshaft seal no 2 has gone.

I suppose it's been cool and nothing abnormal has happened until now. When my T5 had a new camshaft i listened soooo hard afterwards. Took months for me to relax.
I'll see what the mechanic says tomorrow and if it's grim I'll record it. He is a specialist vw van centre.
Selecting the correct lip seal for the application is critical, hopefully VW got it correct.
I’ve seen plenty of the correct type lip seals installed incorrectly, often the damage is invisible from the exterior. Removing the seal invariably damages it so it’s hard to prove poor practice unless you actually see it done.

I can't find anything on crankshaft issues with this engine. Only the seal. Hopefully that's not the problem. Isn't there a sensor on the crankshaft ?
2016 euro 5 140 6 speed 4 motion.
What does the sensor measure ?
Some machinery has vibration detection, I have no idea with VW auto engines.
It’s worth finding the spec for the VW specified seal, there’s far more to seals than fitting in the hole. Material and Shore hardness come into play. example NBR 70 being Nitrile Butadiene Rubber or Buna N with a hardness grade of 70.
Also there are static seals, reciprocating seals and the one you need - rotary seal.
Then there are rotary seals with different speed ranges measured in M/sec.
It’s a minefield, I’d like to think that VW have got it right but let’s face it there are many other situations where they haven’t. Keeping water out of a van should be easy?
If the old seal has worn a groove in the crankshaft the new seal won‘t seal, unlikely on low milage unless there has been contamination.
If the mechanic has scored the crankshaft while removing or installing seals it will rip up the sealing lip surface straight away.
If there is run out on the crankshaft at the seal face there is only so much compensation available from the seal lip flexibility.
Run out could be checked with a DTI (dial test indicator) although hard to do with a running engine as too much vibration.
A scored crankshaft might be repaired with some careful dressing of the damage, it’s not possible to put back missing material, only remove the standing ridge.
Some engines are repaired with a pressed steel sleeve and over sized seal system, no idea if VW do this.
If the second seal has leaked straight away I would be pushing for a warranty repair and most importantly the cause, repeating what didn’t work the first time around isn’t a solution.
Good luck.
So I've spent £500 and I still have a leaking crankshaft seal. They replaced it and it still leaked through the middle. He told me to go back to the main dealer and get them to look at it as he believes there's something more seriously wrong with the crankshaft. There is a noise and they say it's moving around. So I pay vw to look and they can't find anything ?
So what then ?? How much for a new engine? Will vw help with costs ?

I would first insist that the first garage refunds you willingly or with small claims court as they have not carried out the work they have been paid for you need to find someone that knows what they are talking about, just cause you have taken to vw does not mean they are any good, you need to get the end float dti checked for movement in all directions
Will vw do that check when i explain the situation?
The guy i have used is an authorised vw man but not a main dealer.
I'm taking it to vw at Eastbourne on Thursday to look into it. That'll cost more. What a palaver.
The question is, is there really a noise on the engine? The seal issue could be that it was ill-fitted twice and its now ` palm it off` to another dealer? If you`re taking it to a VW dealer to get the seal repaired, mention the problems and ask them to check the Druk ring ( oil seal runs on it on crank) for a groove. They will tell you if the oil seal was fitted incorrectly. I wouldn`t panic too much until you know facts.
