I have recently picked up a T5.1 from a salvage auction, unable to test drive it, but went in with my eyes wide open expecting to find 'something'. Looks like the reason it has mades its way there is DSG related (obvs it hasn't been written off because of the gearbox, but whoever owned it probably had an "accident" to get shut of it).
Anyway, like I say, eyes wide open...
So the issue I was having initially is a sharp clunk occasionally when coming off the throttle, approaching a roundabout for example, or when re-applying the throttle coming out of the round about, it could also be triggered when parking, moving front D to R.
The first port of call was replacing the drive shafts, turns out the offside one was absolutely shot, which may mean that the spider gears in the box are shot as well, but one step at a time. This has certainly improved the clunking, I can still feel something, but it's more of a dull thud and it doesn't do it all the time.
Next as it has done a few miles and I don't have any service history, I've carried out a fluid and filter service on the box, whilst it changes smoothly, it just feels a bit "mushy". This is where things look a little strange. I measured the amount of fluid that came out, it was 7L, afaik it should be around 5.5L, it was also a cherry red colour, which I believe is more likely standard ATF fluid. So could this have been done on purpose or by accident by someone who has no idea, it was so close to 7l that it feels deliberate.
So I have refilled with the correct fluid, it took 6L'ish, this didn't really feel like it made any difference, apart from possibly revealing a slight whine at around 50mph in 7th gear. I read that after a fluid change I should also reset the basic settings, I have odbeleven, so I have done that.
This is the actual reason for this post, after doing a basic settings reset, the van is completely un-drivable. I have come across the term 'snagging' as this feels appropriate for what is happening now. Essentially, when I put it into drive, it kind of feels like it is slowly creeping (much slower than it did before, which felt quite aggressive), but as you apply the throttle you now get a violent shunt as it engages, almost like dropping the clutch. It also does this in reverse. I am hoping this is just a case of having to reset something else in the box.
Any ideas?
