Putting back Ignitions Coils anf the VVT

greenberet123 · 10-20-2018, 01:43 PM

Finally finished my VCG change and am putting everything back. A few questions cropped up right at the end.

1. How deep should the ignition coils go. I just pushed it in with my hand as much as I could, but I'm not sure if it has to be forced down like I had to do with the sleeves. There is still a little gap between the rubber seal around it, and the valve cover surface, but it just doesn't go down any more.

2. According to the Pelican parts article, after installing the VVT we have to 1) Turn ignition on for 30 seconds and then turn off, and then repeat. 2) Use a BMW scan tool to relearn VVT positions. My question is ... why do we have to do both? What does the 30 second ignition step do? Does it not learn the stops as well? Also, can a Foxwell nt510 be used to relearn stops?

Thanks!

1. Use the easily accessible coils to get a baseline for how far to expect to push. Eg cyl 1 or 2. I usually feed the electrical connector in whilst engaging the latch to ensure that is correctly locked in also (just as important). Then line up the point end with the slot and push firmly downwards.

2. Ignition on sets the initial end stops but a fault may still be logged, expecting you to run the service function to teach it in properly
