Hi, I have an intermittent EGR insufficient flow fault occurring on my 3.0TDI Avant, bringing on the check engine light. Been happening on and off (and by off, I mean often seemingly clearing itself and the check engine light) since 2022. No loss of power or any other symptoms. Decided to sort it last month by having a TerraClean carried out at my local approved centre. Two cleaning attempts (including cleaning the EGR cooler off the car) AND a new EGR valve and vacuum solenoid valve later, I'm still getting intermittent EGR insufficient flow faults occurring AND the check engine light comes on and goes off without clearing the fault. Anyone experienced this before and have any idea what's causing this? Thanks Chris

Hi, all you fellow 3.0 TDI owners! Has anyone any experience of split intercooler pressure hoses? I have a whistle under hard acceleration which I suspect is due to a split hose somewhere (see below diagram). Before stripping half the car down to get at the many hoses in the system, in your experience, is it more likely to be one particular hose than any other? Ever hopeful! TIA
