Bruno, I watch many of your videos...and this one saved my day today. The Turbo is now working again on my 159 and it was a "zero $" repair...thank you 👍

[@alfaromeonoproblem]

Thanks for watching and thank you for the support. Please share the video with your friends

Great video. Thorough diagnosis and test procedure. Subscribed :)

[@alfaromeonoproblem]

Thank you very much

(Edit: the P0237 came back after weeks and will remain a miracle to me) Excellent video, grazie mille signore! I had to figure out all this information by my own being abroad with an expedition car, a new Isuzu D-Max with a lot of electronics which I was kind of shocked about. Eventually it was nothing of the causes I suspected and you described. The P0237 error only came when the diesel tank was at 15% level or less and it is probably the electronic controlled tank ventilation. Still abroad I don't have access to tools and parts so today I have to live with it and keeping the tank level higher.

[@alfaromeonoproblem]

Hello. That is very odd.. normally fuel pressure and air pressure do not interfere between each other. You may have a bad ECU or map. It is diesel, right?

[@liamhotspur9182]

@@alfaromeonoproblem Apparently they do. I found it in a Pierburg troubleshoot document affecting the intake manifold pressure. I can sent it to you if you want.

[@alfaromeonoproblem]

Send me please

Today I drove an Alfa GT 1.9 JTD 150hp, hard acceleration as they say, full throttle. At about 180-190kmh, it throws a check engine error and the dashboard says motor control system failure. The car goes into safe mode. I turn off the car, turn it on and everything is normal, I drove it for 210 km after that, but the error remained. Diagnostics showed P0237, Turbo/super charger boost sensor 'A' circuit low. I deleted the error and everything was normal, until I drove it full throttle again. This only happens at high speeds with hard acceleration. Did you have the same experience and how did you solve it?

[@alfaromeonoproblem]

Hello. Yes, that is common. The solution is on this video. Thanks for watching

[@den.dovbakh]

That was great, much respect! Thank you, really helpfull video. It would be great if you made a video about computer diagnostics, for example, 159 model.

Hi bruno what kind of pipes I need to buy to replace the damaged one? I cannot find the right diameter on eper/elearn

[@alfaromeonoproblem]

Hello. New they just sold the entire set. To repair a good thick 4mm usually does it

@@alfaromeonoproblem I was thinking to use silicon vacuum pipes not original spare parts that were I live are unavailable.

Hi, do you know the inner diameter of the vacuum pipes? I want to replace the old ones with silicone ones (before this I'll test the 0.9 and 0.6 bars with manometer)

[@alfaromeonoproblem]

Hello. It depends on the car. But usually 3.5 or 4mm

[@CrowEditss]

@alfaromeonoproblem thank you, i forgot to mention, its a 147 im buying with loss of power only in the low rpm range

I removed my reservoir box due to the physical damage and connected to the regulator of the turbo , so do i face any performance issues related turbo actuating and boost ?

[@alfaromeonoproblem]

Hey. If you do not any leaks and the solenoid is good, yes you need the reservoir

[@lakshminarayana173]

@@alfaromeonoproblem Oh..thank you Sir😊 So I'm adding the reservoir in between the vaccume pump and the regulator of the turbocharger. Do i ?

[@alfaromeonoproblem]

@lakshminarayana173 yes, that's it

[@itsalwaysfake]

Good Video!! Do You use a race chip? I saw somting in the left near to the incoming air pipe wich looks like a race box. Does this work?

[@alfaromeonoproblem]

Hello. Yes it is. I have it for about ten years. Works very well. No smoke and more grunt. Also have it on my sedan JTD. Same story. Will do a video for that too

[@itsalwaysfake]

@@alfaromeonoproblem I think about this very long time. Can you say what you use exactly? I want to buy it now also!

[@alfaromeonoproblem]

Mine is no longer manufactured.. it really was a long time ago. It does not have a name on the box. It was a German site I guess

[@balkancarbalkanfun7540]

Hello my Alfa Brother,should i clean the EGR before blocking it,or there will be no be problem do it without cleaning? Sorry foR my bad English,and greetings from Macedonian jtd Alfista 😂🍻🍻🍻 Btw,respect for your job and dedication! My problem now is the loosing of power on uphill and when i hit in the hole,so my gas pedal not responding on the first half,sometimes there is no reaction even if i press it to the end,then it starts the acceleration right at the moment. Sorry for my long comment and bad English,but maybe you can give me some advice,what should i do.

[@alfaromeonoproblem]

Hello. Do not worry, I can understand you perfectly. I need to know which can do you have and what engine is in it. Thanks for watching

[@balkancarbalkanfun7540]

Thank you for helping me! my engine is 1.9 jtd 8v,the model is 156 and 2000 the year of production :/ Btw,my father now is telling me that it can be the protocomer,that sensor next to the filter) or many other things 🤦‍♂️...

My people say the medical is Five ,,money" ,but you have to find it 😂 The electrician will check it tomorrow,and i will tell in the comment the problem...if he find it of course🤦‍♂️.Big thanks again,and i really like and respect your videos 🍻

[@alexsprint4533]

Great explications thanks! Question please: When i shut down the engine of my 156 2.4 jtd 175, the actuator stay on pressure 20-30sec. I ear a little noise about the regulator (i have buy a new and it make the same noise after stop engine) And after 20-30sec the noise stop and i ear a sort of 'pschiiit' who comes of the actuator and the shift on the actuator returns to its place. Is it normal ?

[@alfaromeonoproblem]

Hello. Yes, it's normal to do that. On previous cars it was less time and often not enough time. So later they extended the time. I have other videos on this subject

[@alexsprint4533]

Is it possible to not have any fault codes and have a leak somewhere?

[@alfaromeonoproblem]

Hello. Absolutely! Low boost normally does not create a fault code on these cars.

[@koziolmichal1]

Can a vac leak cause the car to have uneven idle?

[@alfaromeonoproblem]

Not on these cars. Gasoline cars yes

[@IstrskaPustinja]

When I turn off the car it shuts off very agressively, the sound is like it stumbles on itself. What could this be?
