Alfa Romeo 164 Register.com

I still need to disassemble the tops, but the rest is taken apart and the crankshaft is not looking so good, but that was expected. Next step will be to find 3.2 parts for this engine.

Great work and you now have a lovely, unique and reliable daily driver

That is a good way to narrow down where the problem is

Those sensors are not easy to find, but I believe they have been used in other Fiat and Lancia models.

Thanks for sharing and great that you got it fixed

So I have slowly started on the Q4 again - or rather I bought another Q4 engine, that I am taking apart, as it has some crankshaft issue (I don't no more about it), but it is complete. Whether this engine will be rebuild (maybe 3.2 or more) and put in the car, I have to decide on. Here are some phot...

Great idea and thanks for doing stuff like this

I am in

Have you looked in the specific Q4 workshop manual regarding this? It should be available in the 'Manuals' section.

I can see that the links to equipment are not working, so I suggest to go here and read about HW required: http://www.multiecuscan.net/ The principle is the same, Alfa164diagnostics on this site is just a program focused on the 164, giving some other options - and it is free, but a donation to this ...

That is a good find! Thanks for updating this thread

It seems that there is a short somewhere, so looking carefully at the electrical diagrams I think would be the next step.

Is it a brand new control unit? If so, the problem must be somewhere else in the system, as I assume that the airbag light was flashing with the old control unit? The airbag system should be possible to connect to, using the alfa164diagnostics tool http://www.alfaromeo164register.com/viewtopic.php?f...

You will be lucky to find a set of original rear Q4 springs...

If you do, please update us

I have no idea, but believe that it is the same conctruction on all 164's, so hopefully someone have experienced this and found a solution.

If I understand it correctly (please supply English text when writing here, so google translate does not have to be done by others separately), you have changed the unit, but having the exact same problems, both with lights, fans etc? As this is a pre-FL 164, I don't have experience with this unit, ...

Welcome to the site. That sounds like an interesting project, hope to see that on the tracks in Sweden :) If you look at this thread, it is clear that the ECU is the same for manual and automatics, as it is also used in the 'Q', which is manual only: http://alfaromeo164register.com/viewtopic.php?t=2...

Welcome to the site - your 164 looks to be in good condition

There are many good topics and discussions on this site, looking forward to more of that in 2022

Seems to be easy to find, but maybe not cheap.

Great that you got it on the road

I guess it has given some problems, but I hope you have solved them by now...

That would be an interesting experiment. Please update with what you decide to do

I hope you found the explanation to this. I have no idea what would be the solution when removing the ABS pump...

Air flow sensor? Did you have any diagnostics connected to the car?

I will have to look in my archives, as it might be a Brink that was installed on my Q4 many years ago. I cannot guarantee that I have any information, though.

I don't recall if you did anything around the fuel pump, but my guess would be fuel starvation, most likely in the fuel tank. Does it also happen with a full tank?

Lose connections? Earth connections?

They make a very nice pair

You got a good result for the valve covers

Yes, that bolt size is not easy to find, I used ebay to track some down.

In my Q4 (driver airbag only) it is placed in the center console behind the radio, either above or below the engine ECU, so I suggest you look there for the actual number of the unit.

Welcome, Marc :) My main knowledge is on the Q4, so I am biased 8) I prefer the 24V and that is also what you have experience on, so maybe you should stick to that. The main difference between the 24V Super and QV in handling, I think is mainly down to the electrically adjustable shock absorbers - a...
