Hi

I am looking for an inexpensive fault code reader to determine what is causing my engine management light to be illuminated. ....

appart from MES, alfisti.net also offer a standalone OBD reader :
Autarkes OBD-2/EOBD Diagnosesystem Handgerät - Alfa Romeo Shop - Tuning, Styling, Fanartikel und Modellautos

MES is a lot more extensive, but requires a PC and interface of course. It can do a lot more though

It should do.
I think it's after a certain number of times you've turned the engine on - I don't know how many.
Took a good few weeks on mine.

Brillaint! Only started it a handful of times since.

Found some more related threads and it seems it does just go. But how annoying [emoji2361]

Thanks for your quick reply

After 3 times when the fault is intermittent, that is how the OBD system works.
Stays on when its fatal.

I would guess at about 30 with mine, but it wasn't a 'fault' - just a cheap code reader clearly not being fully compatible.
It took approximately 3 weeks before it cleared.

Well the airbag thing kicked off when using the OBD I can't think it being a serious fault with wiring or whatever cos nothing had moved.

Fingers crossed it will go in the next month if not I will have to find someone who can read the airbag fault and try clear it for me.

Thanks for all the help on the old thread was so good to find others had same issue as myself

Hi Alfa owners. I am having exactly this same problem. Yesterday after doing oil and filters change to my 159 Ti, the guys connected the -as described before- cheap OBD reader and now I have the airbag fault light on.
After reading this post I now have some hope to have this problem solved on its own in a few weeks. I was going to take it to the Alfa dealer but now I will wait sometime...

Cheers from Argentina!

I was told it was thirty cold starts (after the fault is fixed) before an EML goes out on its own with these cars......but have no real evidence to back this up!!

 

[lussoman]

Sounds about right.

Thats more like 3 times when the fault isnt fatal, not 30.

 

[lussoman]

It was 30 / a good few weeks on mine when the OBD reader was the culprit.
Absolutely nothing wrong with the airbag - my incident was about 5 years ago.

 

[ItsMeMarty]

Coinsidence.

 

[lussoman]

With what?

 

[ItsMeMarty]

Reseting the fault code, because the OBDII system cleares fault codes that are intermitend after 3 times and not 30.
I doesnt clear the code but the MIL (engine light)
That is how the system works, light stays on when its fatal.

 

[lussoman]

But not with the airbag.
There's plenty of others besides me who've waited weeks / many start-ups before the light's gone out after plugging in a cheap code reader.
And you can't reset it yourself with one of these readers.
Just a matter of playing the waiting game or taking it to a garage to reset with a better diagnostics system.

I was looking for clues as to why the cruise control was not working on my -06 1.9 jts 159 when the following happened: Ps. If you have a clue about the culprit behind these cruise control-related codes, please share: P0575 Cruise control system input circuit malfunction P0571 Cruise Control/Brake Switch A Circuit Malfunction P0564 Cruise Control Switch Circuit Malfunction

Bonjour, je déterre ce vieux post . Avez-vous trouvé la solution pour effacer le voyant d’airbag ? En effet, j’ai branché un lecteur de défaut sur la prise ODB . Pour vérifier s’il y avait des défauts, une fois déconnectée l’appareil , je redémarre la 159 et Bing, voyant d’airbag allumés.comme Tigero l’a indiqué. je l’ai démarré 10 fois vérifier le fusible numéro 50 il y a toujours ce témoin, airbag rouge d’allumer. merci pour votre aide.
