Ok, I get the glow plug symbol flashing and code brought up the following P0407 EGR Sensor B Circuit Low. However, it is intermittent. Drive to town, all good. Drive home flashes, pull over, restart engine. Then all good. Any ideas why only on occasion. I am also losing coolent. It EGR cooled by the system, and could coolant be getting into it and thus causing the problem? Wondering before fork out for garage and new EGR. Also this after the recall for VW. Cheers in advance.

In 1.6 TDI.
