OK - so if you remove the EGR valve completely, rather than blanking it off and leaving the EGR gear in place, is there any 'real' benefit to removing the gear and using a single silicon pipe rather than leaving it in place with the standard pipe with the t-piece?
i.e. blanking and leaving the valve on costs next to nothing . . . . Blanking, removal and silicon pipes costs about £70.
Does the cost really justify the end result?
All a bit subjective as far as I'm concerned. Agreed the TDi runs smoother at low end without EGR but I aint fully convinced that £70 will make it any better . . . . other than 'looking good' when you pop the bonnet.
