3b s2 coupe resurrection

[newsh]

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.

[newsh]

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,

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.

What software are you running?

[newsh]

Intake manifold earths separated, still just spins.

Mine are all on one bolt.


Has the ECU come unplugged? Can you pull codes?

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?

Ok, I have a 2 and 3 pin plug, but it is 2-2 and 3-3, has not been touched.

I do not appear to have spark (Spark plug resting on cam cover)

When I span the engine for a while it fired once as I let the key go.

[martinws]

Unsure?

I have not touched the coil wiring or plugs since it was running.

It should be fine then. On the stock ABY loom you have two 3 pin white plugs that fire the coils, one does cylinder 1,2+3 and the other 4+5.

I got them the wrong way round first try and engine coughed and farted and backfired like mad but wouldn't run, quick message to Mr Tonks and it was running in 5 mins!

[andy10v]

possible to have the coil plugs the wrong way round like you can on an ABY so it fires wrong?

I really don't know mate, if it worked like that before then I doubt that's the problem, have you checked for spark and fuel?

I notice some genuine injector O-rings, their nice and cheap aren't they

That was my thoughts, cant hurt to separate them as per OEM though.

There is fuel at the rail, I dont have anybody to crank, might try and leave a plug on the cam cover and look through the windscreen?

Yeah, £23ish for 5

The separate earth rings from the intake manifold are now all on one intake manifold bolt, should I separate them again?
