I know dervs usually worse in the colder weather but noticed a significant drop in MPG on my 1.6TDi (CAYC) mk2 recently.
Still starts fine though I get a bit of a smell on cold start now (similar to the smell when on regen)... no running issues, gets up to temp fine, pulls hard (it's on a stage 1 remap also), regens are all ok (oil ash residue is 52% currently don't think there's any DPF issues/blockage) and all the fluids seem ok, possibly it's lost a drop of oil since last service a couple of months ago (just about to tip over to 90k)
Wondering if anyone has had simiar at all? I was wondering if it could be possibly start of some EGR valve/cooler issues? Or maybe something else.
Either way it's booked to go over to Darkside Developments next week for them to take a look but just wondering if anyone had any thoughts.
