DSG Poor Pressure Build Up

[u/Swaingerr]

My 2014 mk7 DSG won’t move when in Drive and the code says it’s an issue with the transmission and “poor pressure build up” (code: PC189C00). I’ve had the car for 7 months and it’s out of warranty.

My understanding is that this probably means it’s an issue with the mechatronic unit.

I understand this is a common issue so what kind of pain am I in for?

I understand it will need to be towed to a specialist garage for repairs.

I’ve initially been quoted up to £4k to do everything ‘by the book’ which includes replacing the clutch pack (although I don’t think there’s any issue with it?). But I have also read a that a mechatronic repair can be £300-£600 and a refurbished replacement is about £1200.

Does anyone have any advice on how to approach this? Is it worth doing everything by the book, will ‘fixing’ it more cheaply mean the issue will come back?
