3b Flywheel modification

[UrS4boy]

there are for a factory diagnostic tool for the ignition angle. if you don't use these tool to check your ignition, you don't need that.

Okay. Live and learn. With no 3Bs of any type (S2, 200 20VT) imported into Canada originally, I don't know all the "3B" tricks. Even SSP No.111 makes no mention of those two pins, just the firing point sensor pin:

If anyone has some official documentation regarding the two diagnostic-related pins, could you please post it up (thanks)

You need one of these.

Not shown in the video below is the TDC pick up adapter that plugs in to the cast in hole on the left hand side of the transmission case. The other end of the cable plugs in to the electrical port next to the timing light cord. The additional flywheel pins are only used to check timing with the VAG 1367.

There are two sensor ports for vehicles with different depth flywheels. They are located above the timing pin sensor & flywheel tooth sensor cutout.


This image shows one of the sensor ports being used for a timing pickup as on the NeuS4 with the V6 engine.
