It would be nice if people list their LE number and production date..

I have a full scanner and run it once I get my Alfa 4C.

If you have the maxisys it will also reset the oil service indicator if you have the latest update installed.

There are two places you need to reset it, one in the instrument cluster (IPC), and the other is in the engine management computer (PCM) if I remember correctly. The IPC actually resets the maintenance minder, and I think (not really sure) the PCM resets some adaptations.

You may have to poke around a bit to find the places to perform the resets, but they are there

Oh, and the maxisys will also allow you to change the stored tire pressures for the TPMS system should you desire to do so

I have two other tools (TPMS scanner and programmer, USB TPMS program and Maxxis Elite )

This is a way overdue update on the progress made addressingmy tranny issues.
First, after nearly 1500 miles of driving since repaired, thecar has run flawlessly.
Just a quick review. The issue I had was that the car woulddefault into neutral anytime I went into the manual shift, in both the N and Dmodes. Of course, it also defaulted in R mode as well. The car ran fine in bothN and D modes, as long as I stayed with auto shift. When it first started, itwould happen every thousand or so miles, and at first I was able to tap theupshift lever and it would immediately go back into the N mode, automatic, in thegear appropriate for the speed I was traveling at that moment, so I could justcontinue to drive on. By about 14,000 miles, it was at the point that it woulddefault into neutral about 200 yards after putting it into manual shift. Also,by this time, when it did default into neutral, I was no longer able to tap theupshift lever and continue to drive. Instead, I had to stop the car andre-cycle the key three times to get it to go into N mode, auto shift.
Over a period of two months, the dealership worked withDetroit, and had replaced basically everything related to the tranny, exceptthe tranny itself, and I still had the problem. At this point, the dealerpushed hard at Alfa US, and they sent a tech with a set of test equipment thatdealerships don’t have. Sort of a flight recorder that collects a lot of info.They drove it with the recorder on board for a couple of hundred miles and manydefault episodes. Then the info was sent to Italy for analysis.
A few weeks later, a new tranny was shipped, along with thewhole kit of related parts – the same parts that had recently been replaced.The tech noted that the new tranny has a different part number from the originaltranny. Everything was installed, and I have had no issues since then.
The tentative diagnosis is that the tranny housing was bentat the point where the valve bolts up to the tranny housing, causinginconsistent or inadequate pressure readings. This diagnosis is not officialyet, so please don’t assume that is your issue. In fact, defaulting intoneutral is the way the car protects itself from a variety of conditions, manyof which have nothing to do with the tranny and part of the approach to isolatethe issue on my car was to eliminate these other possibilities.
Just a shout out for the excellent dealer support, from thetechnical side right up to top management. It was their direct interest and involvementthat got the machine in Detroit fully engaged, and which also led to Italy’sinvolvement as well. Throughout the entire episode, the tech personally calledme almost daily to give me updates on what was happening, who he was talkingwith, and where we were, etc.
I strongly suspect that the tech is more knowledgeable aboutthis issue than anyone out there, and has agreed to talk to other techs dealingwith this problem. So, if you would like your tech to talk to him, email me andI will I will send you his contact data.
I’ll keep you posted if anything comes up, but right now I’mgoing to take advantage of this great year-round Texas weather and drive it!Merry Christmas to all!

Good information, and wise caution to anyone else not to jump to this conclusion

I strongly suspect you are right, and thank you for this, from us all!

(Merry Christmas back, too - and happy new year of faultless driving, as well!)

sptcoupe, That sounds exactly like the symptoms I had. I went through a similar experience with the fix process too. The field rep drove my car with his slew of gauges as well. My fix was a software patch though. Perhaps they've learned more since my time? Perhaps we had different problems with similar symptoms?

I'm glad you're 4C seems to be fixed now. Thanks for the follow-up.

 

[sptcoupe]

I forgot an important piece of info. The code that they chased down was P1CCO-OO - "Hydraulic Pump Stuck Off". That was the extent of the information Alfa provides in their manuals.


RacerZ - my tech actually talked to yours way back when we began the hunt, and it turned out my car already had that flash update. I can't remember - did they replace your tranny, too?


Sorry for all the typos in my previous post. Did it on the fly at an airport.

No tranny replacement. Replaced the transmission high pressure pump and later the pump voltage regulator. Checked tons of stuff and eventually patched the TCM software. Seems to be working fine. Have many thousands of miles on it since.

edit: I need to add that I had a different PC error code.

 

[4C-ophe]

Does anybody have a picture of the TCU shield?
Or even better, a part number?

I think @Docron posted a few a few years back.

 

[4C-ophe]

Well, it was the actuator. Again, as they allready changed it after a few thousand miles.
If I should guess, there is something hidden wrong with the transmission.
Or once again my Alfa dealer screwed it up. Had even a broken screw in the transmission.

But all is fine. Trackday tomorrow ))

Hi guys
I’m new around here. How can one locate their “LE” number (not sure what that is) and production date?
I have a 2015 coupe that I just bought. Also, how can one identify if they have the shield or not?
Sorry for the noob questions. Still learning the basics.

I thought if you have an LE there is a serialized plate in the interior.

I don't have an LE but a std April 2015 build and mine does not have the TCU shield..... The shield will look like the attached pic

Ahh ok. When I’m back next week I’ll have a look.

If your car is a Launch Edition car it will have a LE number plate showing its place in the number of cars that are LEs. Mine for example is #498 of the 500 sold in North America. It is noted on a special number plate on top of your center console. If you don't have a LE you won't have one. Another way to find out if you car is a LE is to look for the side ducts on the front bumper near the headlights. The cars that aren't LE won't have that. If you go to my garage here on the Forum you can see a picture of my car and compare to yours for that detail. The very last run of cars for 2018 may have that duct added only in carbon fiber....it was listed as an option (pricey).

Right. And the only other feature that sets the LE aside from the 'regular' cars is that the interior piping is color matched to the body color. This is a hard one to spot really.

As to the TCM shield, my LE does not have one, is four years old and has lived out-of-doors for most of her life. I drive in the rain and wash her with water. I don't seem to have any issues because I don't have the shield.

Mine isn’t an LE. But my picture looks like the picture you posted, so I’m guessing that’s a shield in there. Would the car have come that way in 2015 or would that have been added later?

Hey can you look at the door jam build sticker and see what month it was made?

May 2015. What are the highlights of a may ‘15 build?

I just remember something posted on here of a cut off date of when they rolled out the shield update. Mine is a April build. More curious than anything
