Thank you for all your videos.i drive second 156,have 146 back in time. Repair alot of things by myself thx to you.Verry helpful and understanding videos.
Thanks for watching and for your support
Hi buddy! Thank-you so much for all the videos. I’ve gained so much understanding watching your material.
I have a beautiful red Alfa 156 2.4 JTD. I had some starting issues which eventually turned out to be a bad relay connection. Unfortunately in the process of finding the fault I think one of the guys that helped me with diagnostics, accidentally deleted my keys and the mobilizer light is now on. The car start by using the security bypass with accelerator pedal procedure. No one here in South Africa can help me program new keys for my car. Is there a way around this. At the moment the diagnostics says that the keys are deleted and mobiliser light stays on. I have checked all connections.
If I can get a set of keys with blue mobi box, will it work? Or Is there another way around this?
Hello. If the keys are decoded there is no way to recode the same ones. You will need some new never used ones. Or you can delete de immobilizer, that can be done on control unit experts.
ive lost all my keys of my alfa 156 and it cost a lil bit much to get new one.Can i buy a used cheap ignition sett? If so, where i can buy the key/untit set?
Hello. Yes, you can buy a used set. The keys, the barrels and the transponder unit. No need to remove the antenna.
If it is the red keys it will not be very easy. Aldo, I do have a new set for sale.
If it is the black ones it's more common.
hello and thank you very much for your videos, very helpful. i have some questions :
1) the garage is asking me to change the bosch immobilizer but it works somedays and not on other days should i just change the immobilizer or try to reprogramme everything relays etc.
2) can it be possible to switch out my steering and swap in an alfa giulia steering wheel into my 156?
thank you so much !
3) if you have used/new parts please do let me knkow thanks
Hello. On the 156 the main immobilizer issue is the ring sensor and its conector and the relays upfront near the battery. In that order.
Do not have those for sale, sorry..
About the mod I do not have any info yet
@@alfaromeonoproblem so should i get a new ring sensor or just replace all the relays to brand new ones?
obrigado.
Start with the ring. If the most common one. The relays is not themselves but rather the pins on the connectors. Apply a good amount of wd 40 and work them in and out several times
Hello i have a 916 spider and i'm having code issues. We've already changed engine sensor but the problem still sussist. Is there a way to dismiss the code sistem?
Hello. That is an old code system. Maybe a control unit repair center can solve that.
hello Bruno, so the transponder box stores the data of the keys, sends a signal to the ecu if the correct key wants to start the car, if I would change the ecu it should start anyways, correct me if i'm wrong. I'm asking because my ecu has some issues, I can not comunicate with the ecu with my diagnostic tool (I tried it even on the bench) the first simptom was that my cruise control stopped working (the light on the dash turned off ) while driving, then the check engine light turned on couple times while driving and the cruise control light turned off at he same time and couple days ago my car did'nt want to start, it was crancking but nothing happend but after few attempts it started, I looked into the ecu but everything looks ok, no signs of water or anything that coud damage the ecu , no burned traces or cold solder joints (I thought it was something simillar that happens to the abs/esp units) I tried to find online info but only thing that I found was a official bosch repair service site with mentioned simptoms and one of them was no communication with ecu wich brings me to conclusin that it is some onternal component that fails.
Hello. The ECU is coded too. I have more videos for that. The ECU talks to the transponder yes to asks for the keys, but it self also has to be coded it self. The cruise control can go out for several reasons, normally a fault code, anyone, will do that. I have videos for cruise control, for no start or hard start, for diagnosing a no start. Helps to know too witch car you have, the systems differ a bit. But here you go:

@@alfaromeonoproblem thank you for reply, my car is 2002 156 1.9 jtd 115 hp, interior facelift, i wil check the videos
Ok, perfect fit. Pay close attention to the ones that mention the relays nerd the battery
Can you not short circuit the IC in the box somehow to always be sending out an accepted signal?
It's possible, but then I'm telling how to steal cars..
Would you consider sending instructions on private e-mail on how to "cheat" the IC?
my friend u wint belive what us my alfa gt doing with me same problem my car with a locked simbol i paid 500 dollars already the service they refresh like everything in the "brain f the car" new program imobikizer blocker everything and my car still showing mi the problem and my car wint start what you think what could be the problem too?
Hello. The Alfa GT uses a body computer.
That means you can diagnose it very easily. With a proper diagnosis machine, of course.
With it you can see if the body computer recognises the keys. Or if it does and if they are coded.
Start with that
Hello , I changed my key cylinder because it was broken and it can’t start now, even with the same chip
Hello. Did you damaged or disconnected the transponder ring?
Are you Italian?
Hello. I'm Portuguese
