2.5TDi AEL pump timing problems

[AndyP]

Reference mark on pump pulley to cam cover. Loosen the pulley keeping the cam timing set. Advance the timing and re tighten the pulley. See how she starts and check with vcds. They are frustrating but once you get used to the tiny movements required to advance and retard you'll get there. The reference tippex mark is the best way I have learned to get a basic setting before fine tweaking on vcds.

Great advice, thanks! Scribed a line with a Sharpie and after a couple of tweaks I could tell by the sound that it was better, plugged in VCDS and it only wanted a small adjustment on the pump to be dead on. Checked this morning on a 1°C cold start and it fired right away

Excellent news. I've always found having an easy to see reference mark on the cam/pump pulley helps no end.
