3b s2 coupe resurrection

[andy10v]

The two white plugs on the ABY harness are all +12v so all they do is supply the power to the coils. They are all live with ignition on. On Andy's harness the coil supplies are all run off the single big +12v supply for the original 3B coil.
Have you checked the hall sensor Andy, has the IM disturbed the dizzy? Also check the fuse for the coil, perhaps the TFSI coils draw more than the 3B unit. Drop me a PM we can work through all the wiring to check all that has been changed

How would I check the hall sensor is working?

Any idea where the coil fuse is?

I have checked all the fuses in the fusebox in the engine bay, are there more under the dash?

Popped the dizzy cap off, rotor is still going round.

Does the ABY have a tighter window than the 3B for hall sensor?

I am reluctant to mess about with it as it was starting,

Intake manifold earths separated, still just spins.

Mine are all on one bolt.


Has the ECU come unplugged? Can you pull codes?

What software are you running?

Easy to check dizzy position, set flywheel to TDC (Zero mark aligned in bell housing window) Check that mark on hall sensor window disc aligns with mark on dizzy body.

I have TFSI coils, 06E 905 115E


Should mine be trimmed?

These are fine in an ABY cam cover, mine are fitted without trimming in the avant.

Cool, thanks.

Unplugged the ECU and plugged it back in, no change.

No, VAGCOM has not worked since I did the ecu swap, even when the engine was running.

Ok, I will check it again, it has not been touched since it was running 3B, and then ABY.

Perfect!

Does this need the resistor 201 changing? most of the RS2 clone chips do.

Or did you buy a known working ECU and injectors?

ECU has resistor mod done, has been tested in a RS2d AAN and working fine.

RS2 injectors are the ones I was using before.

Ok

How about a problem with the wiring extensions for the tps and IAT sensor on reverse IM?

Also maybe pull the plugs to see if they're soaked in fuel

Just reading through again seems you have a MAF problem, Are you certain you got all the pin swaps done right?

[newsh]

Cool, thanks.

Check the OBD fuse. Marked on the fuse box lid.
