I performed the instructions on my GT 2.0 JTS and indeed I can feel better engine running ! Thank you very much for all your Videos :)
Great to hear, thank you very much for support, it means a lot...
Excellent video! Really good explained! Thank you very much!!!
You are welcome, glad you enjoyed it...
Hola, gracias por el aporte que haces a los propietarios de Alfa Romeo... en mi caso tengo un Alfa Romeo 156 Twin Spark 2.0 Selespeed año 2004, anteriormente hicieron un mal trabajo con él, limpié cuerpo de aceleración, cambié Termostato y Bujías de encendido de acuerdo al Manual, el auto quedó irregular en Ralentí, viendo su video realicé el Reseteo de la ECU, como usted lo indica, al salir a pasear y probar por unos 15 Km, el auto anduvo muy bien, suave andar, perfecta pasada de cambios, todo bien. Luego de detenerme unos minutos a comprar a los 15 Km aproximadamente, al retomar el auto, este ya volvió a ser irregular en ralentí, aunque mejoró su andar. Si pueden ayudar, sugiriendo algo, les agradecería. Saludos desde Las Condes - Santiago - Chile.
Super perfect ---thanks for this information...
Glad it was helpful!
Works for me thanks !
Glad to hear
Can it solve the p0606 fault code with a simple reset? I noticed my alfa 147 2.0 ts cut off power at 5-5.5k rpm under hard acceleration
Hey mate, when I did this, the car didn't want to start afterwards, it turns on and cuts off; what could be the problem?
Bonjour où se trouve le relais d immobilzer.? J'ai fait le diagnostic et l'appareil indique que le relai de fonctionnement optionnelle. Tension inférieure au seuil maximal
I need some help with Alfa 156 parts and I’m in Italy could you help me out with a cheap and good scrap or used parts guy for my 156 please ?
Thanks so much again
Thanks for all the 147, 156 & GT
videos...all great viewing. I have recently fitted 4 new Bosch glow plugs in my 2006 147 JTDm but I'm still having the glow plug error. Will a reset cure this problem, or is it possibly another issue? Any ideas?
Yes, there are several things that need to be checked, hook up the car to diagnostics first
Yeah, that worked exactly as expected ... nothing changed.
I haven't tried yet but it sounds like bs
Hey ARC garage - love your videos, very helpful as I'm doing up an Alfa GT myself. I disconnected my battery and the + terminal plate to remove the air filter - when I put it all back together I'm not getting a 'motor control system failure' message. I wonder if this reset could help
It should, but it would be better to hook it up to diagnostic tool to see what is going on...
@@arcgarage thanks, this turned out to be an earth issue. That aside it now starts but dies right away after 2-3 seconds. No error coded whatsoever. on the advice of a mechanic, we've sent the ECU to get checked. not sure what else it could be
Many thanks for your Video, I just want to know can this also reset Airbag Control Module?
I am not sure. However, if you, for example, replace an airbag, or fix the connector, the module will turn off the airbag light on its own, you don't have to reset it...
@@arcgarage thanks I did what you recommended in this video and all problems solved 👍
Hi if I’m having problems with my gearbox does this reset work
You can try, I never did the reset on selespeed...
How do you exit limp mode? I think due to the bad maf it went to limp mode (loss of power, won't go over 3000 rpm etc..). I repaced maf and tried the ecu reset procedure mentioned in the video but it didn't fix it. Can you do it without OBD?
Jesi probao sa geometrijom turbine cisćenje,provjera vakum ventila i solenoida
Can we use shorter way to reset ecu, for example negative and positive cable removed, lights turn on , wait 10 minutes and that's it?
I don't think there is...
Hi, I've just fitted a new window switch in my GT. Unfortunately, everything is working apart from the driver's window which won't go up. Weird as it was working with the old switch. Fun fact : same problem when reconnecting the old switch.
Do you think an ECU reset could help me with that ? (no proxy alignment has been done yet)
Give it a try, but there might be another issue...
What issue is it, do you know?
Hi mate, I have installed and a LPG kit. After the reset, during the idle should the car run on LPG or gas?
Hi, gasoline
Hi. My 2004 147 switches off and then will not switch on again until 15 minutes later and I suspected a possible issue with the fuel pump but don't really know much. I tried all steps to the point where I let the car Idle for 15 minutes and as I was about to switch it off it cut out on it's own, exactly 15 minutes later and won't start again until later. Any idea what the issue might be? P.S. Rear windows not working and tailgate will not open with dash button or FOB.
Hello, i have a problem that my instrument lights, city lights and number plate lights only sometimes work. It switches on and off on random. Its a alfa Romeo 147. Can i fix it with the reset?
You can try, but I think it is another electrical issue...
if i was going to put in MARS position and i slipped my hand to off ( not taking the key ) i havebto do it all again and wait another 45 min? your videos help me a lot
Thanks, I would repeat it
Hi, thx on vidios am have 147 1.6 16v alfa and have like every 1-2 days check engine poping up idk why was on mechanic they dontnow what is the issue and they just removing that issue with dijagnoses is this same method to remove all alerts or? Thank you one more time
Also forget to mension any way to reset manuel proxy aligation becauss my odometter is flashing old the time and not showing how muc km am have on alfa
You can reset the light this way, and possibly the flashing odometer. However, take your car to a good mechanic with a good diagnostic tool that can access all of the modules, and he'll be able to read out the codes for check engine light, and for the flashing odometer as well.
@@arcgarage thank you for you time and help will do it tomorrow morning this ecu rs. And see will it fix some off issues. Thx one more time
No problem...
Will this work on a diesel 147 JTDm 1.9 8V?
Yes
Is it hard to clean the trothle body?
I have 2.0 ts in my car, i asumed that maf and trothle body are victims for slower reaction of trothle.
It is not at all, but you have to be careful since the ECU is mounted on the top of it. You can also take a shortcut and clean it while it's mounted...
Please make video 😁😁
Will do...
Excelente video!! , sabes el motivo por el que aparece fallo control motor?
It need to be read by diagnostic tool...
Why is your Negative next to a + sign?
Might be a stupid question but if the car has been remapped, would the ECU reset wipe out the remap and return it to factory standard ?
Thanks for the great videos
When cars are remapped factory maps are removed and new ones are uploaded. So I don't think that ECU reset would have that effect.
Hello, I will use this procedure, to see if I get to remove the "open trunk" signal that appears to me and I am not able to remove, (and the trunk, is closed). Or it's damaged the lock...
I think that you have a damaged lock...
@@arcgarage I think it so: procedure, not worked😥. I find it difficult to remove the trunk panel and expensive the new spare. My problem, above, is that I don't have time to do myself 😕.
If you can't find time, take it to a garage, it shouldn't be too expensive... It is a simple fix...
Check the wiring between the body and the boot door. Mine was damaged due to several open-close cycles and overheating under the sun in the summer, and some wires isolation was damaged. Could fix it with some strip.
Hi! I have a burnt "body computer" on my 147, and I read that if I install a second-hand BCM, the engine won't start because of the immobilizer (key + BCM + ECU won't match). Can this procedure help to get the car working? If not, have you any idea how I can install a second-hand BCM and make it work?
It won't help, you either need to reprogram the bcm, or you need to buy complete package from another car
@@arcgarage : in order to reprogram the BCM, do I need to be able to read the data from the old BCM, or does Alfa Romeo can recreate a suitable configuration (they should have all the needed information)? I looked at the old BCM and I cannot find any EEPROM on it, any idea what component it is?
guys I changed my driver window switches and all and I can roll down passenger window but cant get it back up on driver side switch only with passenger side switch could this be solution?
It could be due to faulty window controls, but try this ruclips.net/video/Ph73_9_2KvU/видео.html
Hi Ricardo my 147 facelift 2.0 is only revving up to 4500rpms does the reset help with that too?
It sounds like an issue with MAF sensor
It could be because during start up the car idle above 1000 revs and then as it heats up then it goes to 1000rpm I’ll change the whole MAF and see what happens
Hola saludos en mi 156 2.0 16v las RPM tardan en bajar este reseteo normaliza este problema? Saludos desde Argentina
Hi, try it out, not sure if it will resolve your issue...
Hi!This method works also in a diferent engine?My is 156 jtd 140
Yes it will
Ok.Thank you
@@filipesilva1395 No problem
Q: Is this orocedure available for Alfa Romeo ¹⁶⁶ 1st series 936
I am not sure...
Hi. Is the same procedure for my Spider 916s 2.0 TS 150HP Face 2 ?
As far as I know it is...
@@arcgarage Thanks a lot.
For marea and bravo
Is it imposible?
I think that it won't work...
hi need some help i just installed a new EGR velve on my jtdm 147 and now i'm getting a 'motor control system failure' message. the car starts ??
What is the code?
@@arcgarage no code just ( motor control system failure message ) car starts fine but I just noticed that there is a whistling sound coming from the turbo I think when you rev the engine
Do this worck on alfa gulietta 2013
Hi there. Can this be done on 159? Thanks
Not sure if it works on 159, didn't try it
How do you reset the ECU if you can’t start the car due to immobiliser error?
You can't
Hi, I was wondering - if you do this, do you have to put in the Alfa Romeo code? I have a used 156 2.0 Twin Spark, my immobilizer locked the steering wheel, so I can not turn. But the engine starts no problem, everything works except the steering wheel. Will removing the battery for some time reset the immobiliser, or the steering wheel lock somehow? I am desperate, nothing works and the steering wheel is locked. The car is otherwise perfectly fine but I cant seem to unlock the wheel
Many thanks and keep up the great work with your videos!
You don't have to enter the code, on 156 immobilizer can't lock the steering wheel it is due to the sw lock
@@arcgarage Thank you! So you think unplugging and plugging battery back might help with the steering wheel lock? or is that a mechanical issue? I dont know what else to try, everything else is working just fine and the car runs, engine starts and so on, I just cant steer due to the lock of the steering wheel.
Many thanks!
@@adam2664 It is a mechanical issue with a steering wheel lock
@@arcgarage okay then, thank you. I will try to dismantle it and have a look. Many thanks!
@@adam2664 No problem, glad I could help
hi, my miles keep flashing on my alfa 147 ...what can i do ?....thx
Here's the video ruclips.net/video/ReZXYlgILAw/видео.html
my Alfa has been modified by famous "chip" software..someone messed her up fuel/air now,it consumes more fuel than usual and have huge black smoke after 2.800rpms all to 4.000rpms any way to cancel that software modification?
Take the car to reputable tuning shop, and they can remap the ecu for you using the correct software, or they can even revert it to original
@@arcgarage now i noticed also that she swallowed 4l of selenia 10w40 in 1.000km 🤦
Sadly this didn't work on my 1.9 8v alfa-romeo 147, after changing a split upper turbo pipe
You might have a different issue...
Not working for me in Alfa Romeo GT 2006
realy is it work?
Yes
has anyone tried to fit a 1750tbi engine in a GT?
Not sure, I was thinking about it, but it was impossible to source a good 1750 tbi engine, so I gave up on that idea...
@@arcgarage I asked a mechanic and said that my only options are the 2.0 jts that was problematic engine, the 3.2 and the 2.0 twin spark. Would be amazing though if we could fit the 1.8 tbi with the 240hp like the Giulietta QF.
After a while its horrible again...:(
You might have a different issue...
@@arcgarage its a problem,but i dont know what
