What does the Distributor Hall Sensor do?
It's simply a replacement for the contact breakers of a regular distributor, telling the ecu when to charge the coil and when to fire it.It works using a digital on/off mechanisim, using three connections-pos, neg and 0. A slotted wheel spins around and blocks the pickup once per spindle revolution. (The 8v distributor has one slot in the wheel, 16v has four.)
Fault code 00515 Hall Sender G40 signal outside tolerances
TO Bring the Hall sender unit G40 back inside the tolerance, you must use VAG.com because the timing is controlled by ECU.
To do that go to 01 engine, then measuring block go 07 then
loosen the mounting bolt of the distributor then turn it anti or clockwise until it gets inside the range.
