Today I decided to tidy up my 147's wiring around the fuses under the steering wheel.
I disconnected the battery's negative , disconnected two plugs under the dash ( on the body computer I think ) then reconnected them...

Put the key in the ignition , turned to "mar".
My car then suprised me...

Every light had a failure come up
Flashing mileage
Fuel guage not working & flashing fuel light( full tank )
Can't lock car with alarm & remote (as if it thinks something is open)
I have to lock each door individualy with the key

I think the proxy alignment is out, I heard that an ecu reset is required .
Will the ecu reset on this site work?

I've put down what I'd check if I had the symptoms you describe plus I can't see that an ECU reset can make anything worse!
Is it possible to reconnect the wires you disconnected the wrong way round - generally it isn't but worth a try
Did the connectors go fully home? On another car, I once had a spade connector in a plastic connector come loose so there was no connection.
Did anything else get disturbed?
Check the fuses

I'd replug everything after giving it a lash of contact cleaner.

Don't go to a Dealer. You'll be much better off going to see Chris @ Alfa & Omega on this one. If, you can't come right that is.

I've just disconnected and reconnected them, problem is still there.
I also went for a drive , I then discovered that the rear indicators and rear fog light aren't working either . cant confirm if the break lights are working as I had no one to help me check.
Can't lock the car from the inside so I have to drive with the doors unlocked .

Not sure if its safe enough to drive anywhere without indicators and possibly break lights not working.


TheMystic.. do you have any contact details for Chris?

Think you may need to reset the ECU. You could take it to a dealer. Prob cost £100 or get alfadiag and and talk to rarebear. He will send you a cable. Cost a bit less. Then you could clear all the faults at least

Thanx for the replies everyone! :)

I managed to fix the problems myself just before seeing Smaky's and CJO's replies so couldn't use those methods.

What I did was ...
Disconnected the battery
Disconnected the connectors
Reconnected the battery
Disconnected the battery
Reconnected connectors
Reconnected the battery

Problem solved:thumbs:

I remember when I fitted the towbar to my 147, I did much the same. I disconnected the two big cables in the fuse board under the steering wheel in order to fit a iginition fed supply for my electrics. Upon reconnecting and starting the iginition to MAR, the car said immobliser error and the engine just would not fire up. I didnt have any error light though and it was cured after leaving it 30 minutes (I was pacing around like mad for 30 mins wondering what I had done and then came back and all worked!).
I think it has something to do with the Thatcham system to prevent hotwiring or something!
