:confused:

A few weeks ago my 146 wouldn't start with the code light on and the injector light on and blinking once. A few ignition off/key out/key in seemed to fix it.
I made the mistake of going away for 3 days over the festive and now the code light is permanently on and disconnecting the battery (and leaving it overnight) does nothing.

Any thoughts on likely get around - I do not have the master key (only 2 Silca copies) or the code card.

I have a feeling of impending expense coming over me.

Try a new battery, the code only likes fully charged batteries for some reason and with you saying you wnet away for a few days your battery may have discharged if it's weak.

Nope.. tried a jump start from a running car and that didn't 'put my lights out'.

Anyone else? - can I phone an Alfa dealer and get the emergency code from them?

Over the cold spell I had my code light come on a couple of times. Didn't actually stop me starting or driving the car though. I only mention it as my battery was very, very weak. I've now replaced it and hadn't had it happen again, touch wood.

Same happened to me after changing a duff battery. Simply disconnecting the battery isn't enough to completely discharge the system to reset. To do this you have to connect both battery leads together for 30 minutes.

I did this and my code light hasn't been on since and it's been a long while now :)

I think Wrinx was talking about the battery in the key and not the car. ;)

After charging the battery, clean the relays in the front of the engine bay and also check and reseat all fuses.
This is often caused by a faulty electrical connection. I had major issues relating to the fuel pump and lambda sensor relays in both my boxer and TS.

There's no battery in my key and the car starts fine with no warning lights !!

I use an aftermarket alarm for alarming and opening doors, which is why I have removed the one from the Alfa key.

Temporarily disable the aftermarket alarm. These can cause issues and are known to drain down batteries.

BTW, where are you in Ireland?
EDIT: Hang on.... MO4 you're not the guy with the issue...

....but there's nothing wrong with it :p
just pointing out that it appears that a battery is not needed in the key to start the car (or is my immobiliser disabled?)

I'm in Meath btw, where you at McG?

Yeah... sorry wires crossed. The battery is for the alarm radio transmitter in the key, and the black 'Philips' branded chip near the stem of the key is the transponder for the CODE system. This doesn't need power as it's powered through induction from the coil surrounding the barrel in the steering column, like RFID.

I'm in Sandyford BTW.

Well today I had the pleasure of speaking to my Alfa dealer who told me that a code card for my car is not available from Alfa UK and I will have to buy lockset/ecu/code box etc.

AS the connector from the code aerial - which sits round the ignition barrel - to the code box - which is on top of the fuse box (yellow box) runs around the column, it could be worth checking that it hasn't got snagged/frayed on anything, or got a bad connection into the code box.

Otherwise you could need a full set :( . The only good nes is that you don't necessarily have to actually change the locks - I've known people tape the replacement key inside the column shroud - so long as its near the aerial picks up the signal and tells the code box to talk to the ECU...

If you do get stuck, call me on 07976 384980 or PM me and I'll sort out what you need....

Apparently the code box can be disabled, anyone got any idea how/who?

Time to bump this up again, guys. After discussion with Dingo, we established that his was a late (plastic-topped) engine - so basically same set-up as a 156 - ECU on top of throttle body. On this basis, I've supplied him with a set from a (running) 156 consisting of Ignition key/switch, aerial and lead, code box, and ECU to try. After first class post took 5 days to deliver :mad: he's tried the set-up today, and its no different... :(

He's P155ed off, as am I. Anybody any other thoughts? Is there something odd about the late 145/146 that I don't know about?
Any help appreciated.

Richard

I read about the code box being disabled on www.fccuk.org as the Fiat coupe uses the same system. I think it costs about £170 IIRC.

Right, almost a month on and I am still no further forward :(

I have replaced a matching code box, ECU and key which came off a 156.

The CODE fuse in the fuse box is whole.

Does anyone have any thoughts??

Finally, I have given up after running up my phone bill by calling the world and his dog

The car is going to an Alfa specialist next week, it looks like the fault may be a sensor rather than the whole ECU/Code box thing.

The AA man arrived and connected the battery with the ignition on and the code light went out, injector light stayed on and the car STILL wouldn't start but at least it's something different!

Anyway.. watch this space! :rant:

Richard, thanks for your patience, you should have something in your hands by next weekend.
