When the key is turned to start to warm glow plugs on cold morning startup, the glow plug light on panel shows for 2 or 3 seconds and drops off. On startup, the engines starts on compression only after 15 to 20 seconds of turnover. I could just replace the glow plug relay on the firewall but that cost $138.00 and VW will NOT accept returned electrical components if that was NOT the problem. What should I check for and what test can I do? I am very good with a VOA meter.

I have the same Problem on my TDI I just changed the glow plugs and the heat sensor but it still doesn't affect the warming time. I was told that there is a modification that can be done to the engine to increase power upon start up. Does anyone know about this??
