Thanks for the reply Mac. I thought the same, immediately suspected a head gasket or something similar. Coolant has held perfectly for thousands of miles so am thinking its not coolant related! It seems to be something to do with allowing the exhaust gas back into the intake is causing the smoke? For the life of me cant think what.

Thanks for the reply Pete, Wow thats interesting, had no idea. Guess i could jam something down the vac hose and connect it further up. Does having the egr disconnected not mean it could fail emissions? I guess its operation doesnt impact what comes out the exaust though? Its just slightly concerning knowing the issue is present. Its like a light switch, if its connected smoke, disconnected no smoke. Jim

2006 1.9 tdi BLT PD130 completely stock Egr vac line disconnected car runs perfectly, nothing to report. Engine light is on. Been running like this for 8k miles. Egr vac line connected (egr has been replaced... twice) Masses of white smoke through the exaust. I believe the EGR opens the valve when idling or at low rpms? If sat at a traffic light at idle for a few seconds its as though something is building in the engine and all comes out as white smoke when I pull away. I left the car on the driveway idling for 5 mins. Went to pull away and filled my street with white smoke. In my eyes when the egr valve is allowed to open (at idle) something is getting into the intake and causing the smoke - help please. Apart from this the car has no issues, just need to get the CEL off to pass the Mot!
