As your being ignored @Loz and have asked nicely, mine was the aux belt tensioner apparently...but which tensioner?
I thought Loz was asking me directly and I answered. Not sure how I ignored him?
Called the stealers there and my van isn’t affected by the tension belt recall (or it was done before I purchased it as I’m the 2nd owner - he couldn’t confirm if it had been done but confirmed it wasn’t on the system as requiring it). However the van is due the ecu reprogramme which he called a “fuel campaign”. Said I can get it done free even though I’m out of warranty
Im not sure what it is but I suspect its in relation to the Volkswagen emmisions scandal. I used to have an Audi A4 that was affected and I had to take it in for a ECU reprogramme so my guess is that its the same for my T6. Im not going to take mine in though as I am confortable with my MPG and it passed its emmisions on the MOT last week and my thoughts are the re-programme could make it either stay the same or make it worse. Im not willing to risk it.Do you have any more details about the "fuel campaign"? My van is also Dec 2015. Thanks
