Hey guys

Looks like I either A) really need a trickle charger or B) need a new battery. Had to get the RAC chap out to jump start the car.

He used one of those portable jump start things. Once I got her fired up I had a "EFI - Fault" on the LCD display. It stayed there until I got home. Parked in the garage turned off and then clicked the ignition and the fault had gone.

Any ideas what it means or did have its nickers in a twist?

Mine occasionally does this, i think in my case the throttles need setting up or one o2 is giving up as i have one exhaust with more coot on than the other. some people seem to get it after washing there car or if it gets very wet too. It should clear if you press the pod control button.

Sadly the fault codes are not much help with this one as no letter is diplayed.

A flat battery will register as an EFI fault.
Mine had a very flat battery recently and has been showing an EFI fault ever since.
She's in for a Service now and will be reset.

Thanks chap that must be the cause as it would have started with a near dead batt. I take it they just plug the laptop in and reset the error codes. Must say it was annoying driving to the local club meet yesterday with that constant beep lol

I thought if you go into the Pod menu by pressing the main pod and fog button together and then scroll through the screens you will come across a "reset screen" if you press and hold the fog button for 5 seconds it will clear any stored error codes (providing there not still live), only thing is you have to reset your gear change light settings and time again.
Hope this helps

Tried resetting and it still shows up. Looking at the battery voltage on the display it says 11.8 and then drops to 8 when I turn ignition could the ecu be confused and thinking the battery is flat? It says theres no faults when it it does its start up routine, only shows when engine is switched on.

Put a multimeter on the battery terminals and check voltage drop when cranking, Not sure but I think there should be no more than half a volt (0.5v)drop when cranking. Maybe battery is naff because when the engine is running and the alternator is charging there is no fault and correct voltage is seen on the pod.

Bit O/T but I assume that if I press the button to silence an error code and it goes away not to return I don't need to worry about it?

I'm only to worry if a code is there all the time?

Quick update, fitted a new battery today and the fault is still there. Tried the "restore to default" setting but keeps comming up when the engine is fired up.

Is there a chance that the AA's booster pack has buggered my ecu?

Datson,
I've used a jumper pack about 8 times on Tuscan and had no problems. If I was you I would buy the Data cable from Clever Trevor and download a copy of the ECU software so that you can check for faults for yourself.

It really is worth the 40quid to put you mind a rest smile . 9 out of 10 times theres nothing wrong! wink

Right just an update, got her down to dulfords last night and had the ECU reset, aparently it was showing every error under the sun (so they knew something wasnt right). Aparently booster packs can sometimes cause this, seems right as rain now, best thing was they didnt even charge me for the hour of their time smile Now just to sort the passanger window and boot
