Sudden grinding noise and van rolled to alt.
Oil leaking everywhere…
I have heard a couple of clunks the last few days while reversing. Box super smooth, undetectable gear changes. 57k miles, oil replaced at 37k and 56500 after second remap.

Broke down at 3 this afternoon, RAC just phoned saying they ll come tomorrow .
 
Oh jeez. Any ideas where the oil is leaking from?

You think it's anything to do with the map?
 
In the cold light of the day, using my brain and not my guts I think it is not the gearbox. Last night I sent the photos to the remap company asking to scratch their brain about this is issue ( easy to blame them immediately). In the end we both agree it’s not related to the remap. We will see once the garage will have a look but I think it’s not the box at all.
Yesterday was very wet and it looked like a oil leak but today I can’t see anything there! It is all perfectly dry.

After this chat today I was confident about the issue and switched the engine on again and there was no flashing light on the dashboard. Nor messages about the box.
Suspect number one at this point is the driveshaft.
I had a Pendle remap engine and box. Pendle remap superb for engine. However I wasn’t 100% happy about the box, a little bit over reactive at the push of the pedal. Instead of using torque it was downshifting even at light touch of the box. I had a chat with another company ( well known here) and I had it mapped at my taste. Superb job. Gearbox changes even faster than Pendle and reacting to the pedal exactly how I wanted. More use of the torque when lightly touching the pedal instead of downshifting and downshifting 3 gears from 7th when immediate power is needed.

Hard to say, IMHO, if it was the map causing the issue. Additional torque added a lot of strain to the poor driveshaft and sure it didn’t help. I always had my cars remapped, the first was in 2002, by reputable companies and really never had any related mechanical issues.

Let see what is the exact outcome when the garage will be able to have a look. ( they said they can’t look at it before 31st of July).
 
@Crazymind are you thinking that it's a stripped drive shaft?

Yes. Now I have got a terrible feeling. I remember the T5 was an easy job to do. I think the T6 has got a different design to the shaft. To replace the planet gear with spline of the Dsg it’s a box out job and dsg rebuild .
Anybody more competent could shine a light and save me from Heart attack?
 
A bit of oil in water goes a long way. It would be a mess under there if it was catastrophic.
Also, who mapped your box? I’m considering it. The DSG is capable of massive torque, so it is very unlikely it’s map related but more and more negative comments are surfacing about Pendle.
 
Pretty much every fluid used in a vehicle has a distinct smell, with that quantity spilt it should be fairly easy to determine which.
There is also a distinct difference in viscosity between water based and oil based fluids.
It takes a very short time to check fluid levels other than the gear oil, as others have pointed out oil doesn’t disappear. That leaves engine coolant or adblue as the source.
 
Before it was towed away I have checked all the levels. All was good. No leaks anywhere. Now the van is at the garage and I have no chance to inspect further.

It looks great even on a tow track :)
I would have dumped any other car for doing this to me. Not the transporter :) so far being the least reliable vehicle ever owned. Still can’t see anything else that could possibly replace it.
 
The grinding noise and coming to a halt is obviously a problem but could the "liquid" under the van have just been the aircon drain or water from the scuttle area depending on the weather/use at the time and angle on the road when stopped? As has been said "oily" leaks do not dry up overnight and disappear!
 
Hi folks! Enjoy the horror, Vw dealer finally managed to look at the car…
Well known issue, a bit scary that it’s happened to a 2016, 57K mile van already. Has the van been in sea water (floods)?
Will they replace it dry or lubed???? If I were you tell them to grease and maybe pull the opposite side to check.
