    7 Speed DSG - Code "RET"

    Hi guys,

    Would appreciate some assistance.

    Am having conflicting views. I have been told by my local VW dealer that the gearbox is sealed for life and doesn't need a service (i.e oil changing), whereby a local VW specialist says it needs changing at 20,000 and 40,000 miles?

    Can anyone confirm definitely whether this gearbox needs servicing?

    Is the sealed for life trustworthy? Have there been any failures on these gearboxes which would have been avoided if they had been serviced?

    Thanks guys!

    The 6 speed DSG needs the oil and filter changed every 40,000 miles. The 7 speed DSG has no service interval.

    Manufacturer: VW, Date(s) Used: 05/2015-09/2016, Model: Golf Sportsvan (SV), Transmission Code: RET, Transmission Type: 7A, Remarks: In 2014 an all-new successor to the Golf Plus was revealed, the Golf Sportsvan (SV) 0CW Gearbox

    The problem with the 7 speed DSG is the oil contaminates the electronics. New to Golf 1.6Tdi Dsg 2010 on 17k miles. DSG QUESTIONS

    Thanks KeithUK! Much appreciated. So from the link you kindly supplied I should insist the dealer changes the oil in the final drive? Or do you believe this would be done under a normal servicing regime?

    As you've said there is no service interval and I've said.

    There is final drive oil to change but the oil in the Mechatronic cannot be changed and indeed the manual says MUST not be drained as it cannot be replenished. The VW "expert" you have talked to needs to re-educate himself with ElsaWin on the difference between the DQ200 and DQ250.

    Thanks Crasher.

    Is that oil changed as part of the VW regular servicing regime? If not, when would it be changed?

    If the VW dealer says it doesn't need changing how come it was changed as part of the VW regular servicing regime!!!

    Sorry I might be causing some confusion.

    Crasher said "There is final drive oil to change" and I was asking if the VW dealer would change that...I understand the oil in the gearbox is sealed for life and cannot be changed. I was asking about the oil Crasher referred to in the final drive.

    Thanks,

    Technically it is filled for life but unless changed at around 50k, that life tends to be curtailed....

    Ok think I got confused before.

    So the DSG boxes were.originally filled with synthetic oil but it was found that oil was causing problems with the electronics so VW changed to mineral under a campaign (presumably done at service).

    So I need to know whether my car has had the synthetic already changed to the mineral or if it was filled at manufacture with mineral oil?

    Is there anyway of telling other than asking dealer?

    My car was first registered in September 2015.

    Thanks.
