Today i was discussing with my mechanic about testing the engine timing,he said the reading can be done with the modic3 and compare it with the BMW specs.
That said,he added that all the vanos equiped engines gone through UPGRADING or UPDATING not too sure what he meant,but the bottom line is that he said there is a kit for the vanos BMW made modifications to, and if the original factory vanos is in the car,it should be replaced by this kit....
Has anyone heared of this KIT,or done this type of installation?

TIA
