Engine died twice...

If you have Hall sensor error, it will go into limp mode.
This is normal.

If you want to reset the ECU you can disconnect the battery terminal, pull the ECU fuse or disconnect the ECU connector. The fault memory will be cleared instantly.

Or you can wait for your cable to arrive...
If you replaced the Hall Sensor and there was no improvement, and there is still the same fault, I would start checking the wiring...

EDIT:
I just read that your dash went off except for the battery light, this sounds like a bad ground, bad fuse, voltage regulation or charging problem.

Thanks mate, have disconnected battery and checking through.
I should correct that all of the recent episodes all dash lights went off including battery.

[Al Wyn]

Havent read the whole thread Lloyd but recall years ago had a simular thing on one of my S2/RS2s and it turned out to be one of the cables on the alternator that had almost completely corroded through.

Sorry Lloyd i meant starter motor

Yea, definitely a power supply or ground problem then!
Check all of the important grounds in the engine bay. Make sure nothing is loose, make sure nothing is corroded.
Check the ground on the battery, make sure it is well attached etc...

If all the lights go off your car is just losing power.

[Lloyd]

Dash illumination lights stay on as do headlights, radio etc. Also tacho and speedo still work.
Its the central dash computer and 3x3 /'ok lighs that all go off when the engine cuts out.

Having cleaned up a couple of earths and reconnected the battery boost is back in town.
Lets hope it stays around !

[A80Avant]

that is a weird one.... hope it gets solved!

Well if your trip computer turns off and the cluster it is still an electric problem I think.
And the reason for the hall sensor error might be because the ECU has very good voltage regulation, so it stays alive just a moment and registers no hall sender pulse coming in before shutting down.

S2 Issues

Sounds similar to my issue. Does rev counter instantly drop to zero at same time. Just spent 4 hours checking all supplies to my ECU and removed and cleaned contacts on fuel pump relay too that looked a bit pitted. IF sensor and cable checks ok back to ECU pins then start checking all supplies and earths...

Are you still having this issue? I seem to be having the same issue and there are no codes saved

Thanks to Al for pointing me here as I'm suffering a similar problem at the moment too. So may potential causes though by the sound of it.

I'm gonna check my battery connections first as I had those off recently and have an amp connected too. Let's hope it is as simple as that but somehow I doubt it.

I recently had the ignition reader coil replaced on mine so the ignition switch issue starting to ring alarm bells too...I'll report back after the weekend.

Exactly the same symptoms though which is interesting

Well a problem shared and all that Tom Hope you both get to the bottom of it soon.

Yep and had the codes read. It showed about 6 faults all at the same time . spent more time checking cables last night but starting to wonder if its an issue with the fusebox and underside connectors...

Fusebox

Sorry for hijacking this thread

Fusebox...now that rings another bell.....

When we were in France the onboard computer, stereo and a few other bits failed and discovered it was a blown fuse so I replaced that and everything seemed fine afterwards.

However, I do remember seeing that I had a fuse missing in one of the ports that related to high speed radiator fan(?) (perhaps it was fuse 5 maybe?). Assuming this port was there for a reason I plugged the correct voltage fuse into there from the new fuse pack.

Could this have had a bearing on the problem?

As you can probably guess by now, I'm not mechanically or electrically trained

Having just rebuilt my car ready for tuning, I thought I should take it for a drive.
Unfortunately, my weird cut out problem endures. It died three times on a 20 mile journey. One time caused a nice jam and wouldn't start for 2 minutes.

Anyway, it occurred to me that whilst I've changed the ignition switch, perhaps there is an issue with the barrel itself? Hanging a chain and clifford alarm/imob fob on the end tends to induce the key to turn back a notch and turn off the engine, especially with bumps etc on the road. Thing is, there seems to be very little friction in the barrel to stop it being turned back.

Anyway, I've disconnected the chain and fob and managed to drive home without issue.

Could this be the problem after all? Maybe I need the barrel rebuilding???

lets hope so!!!!
