How much should a dpf cost on 2015 vw cc? Thx

Currently, around £750 plus fitting so £1k. Has to be a new clutch to go with it, they work better matched. That will put the bill up to scary amounts (+ £1500) but do it once, it should last you another 100k IMO.

Mine's a 2013 Passat CC and I've just found out what rear shocks cost. OMG. I need two.

Apologies, for some odd reason I read your post as a DMF. New one around £150 and not too hard to fit yourself.

To be honest I've no idea, but there are a lot of variables. Are you doing the work yourself, where about in the Country are you, what quality parts etc.

I would suggest searching a couple of online suppliers, see what work is involved and get a couple of quotes from local garages.
