Hi all.
I need your help. I was driving my Alfa Romeo Giulietta when it gave me a check engine warning sign then it shut down. The initial investigations did show that there was low compression on cylinder 3 & 4. The gasket was blown between the two cylinders. The Multi Air Unit was faulty as well thus had to be replaced with a new one but now it is failing to start. It does crank but cannot start. The following was done on the car as well:
• New cylinder head gasket set was put
• New oil filter
• New spark plug set
• Full cambelt service

There are no faults or warning signs by the dashboard. An electrician did check for electrical faults but couldn’t find any. The mechanic says there is no power to the Multi Air Unit. What other options can we look at so that we try to rectify the problem?

Thanks in anticipation.

The car is with the mechanic so i am not sure what he used. I will have to ask him. Is there an effect if you dont use the Multi ECU scan?
I think this is your problem. Your mechanic is not an Alfa Romeo specialist, and may not be using the correct software.

Question. You started the post with extensive work having been done. Who did this and when? If it's your same mech that cannot read error codes.....

Get to specialist as the guys are saying. They will cost you way less in the long run.

MultiAir is a specialised system even though it may be easy to install. Other cars don't have it. It may require priming procedures and calibration that can only be done when using proprietary software. If the engine warning light came on, and the ecu shut your car down, then it WILL tell you why. If your maccie can't read this then you need another maccie.

I am with Ian, your car ran with the old multiair system, and after the change it doesn't. Your mac screwed up. It has nothing to do with the gasket problem.

Is there oil pressure in the system, does the electronics work?? Does it need a reset?
