search for the thread on the euro smg flash update. it requires the software that usually comes with the inpa one called winkfpt. make sure you have the latest version of winkfpt, read the instructions on how to setup that software. the flashing of the software itself doesn't require a battery charger but the adaptation does so might as well while you're at it.

the software you bought should have came with inpa. what you critically need are the DME remaps. just trust me on this. go do some research first man.last thing you want it to fly in blindly. i waited nearly 6 months of studying before i tried it on my car

I recommend researching and studying. Then experimenting slowly and seeing what things do. If you screw something up, look for help since I'm sure someone out there has experienced it

Bleeding clutch and smg didnt solve issue.
Still look for a way to diagnose gps.
Gps is my last alternative before drop the box
And rebuild it

did you use inpa to run the clutch, actuator and adaptation reset?

Can you explain the problem in detail?
Like when is the problem and what is happening? Flashing 4 in display when changing from 3-4 at High rpm?

When changing from 3-4 at high rpm it
Doesnt engage and flash the number 4
On dashboard. Then I shift to 5 and back
To 4 w/o issue.
Have replaced spring/readaptation/bleed
Clutch and gearbox actuador.
The codes i have are 177/178 and 68 but
No cog on dashboard.
It is hard to believe a 45k tranny is bad

It most likely is not your tranny.. Do you experience same problems from 1-2 & 5-6?

As far as I've read about GPS sensor, it is common that you will either have problem with gear 2-4-6 or 1-3-5...
My problem was with 2-4-6.
Someone told me that very often it is enough to just run a adaptation to calibrate things into factory settings/values again.
If anything is stuck or slow or not in position regarding gearshifts, the tranny will go in emergency mode. Which is what it does when the gearvalue starts flashing.
It will also go in emergency mode if the GPS is unable to see that gear is not in correct position. (even if it is in position.)
This problems is also more common to cars with low mileage due to less use that make things more stuck.. you understand? I don't believe it is GPS, but I cannot guarnatee it.
My opinion is that it mot probably is some "connection" that job is to change gears is stuck/slow, which cause a problem to get things in correct position. Or at least, this was my problem.. Mine has low mileage as well. Older people have had the car more or less in a garage for the last 5-6 years

Why do you believe the tranny is not bad?

Because, I have googled and read about this problem hours after hours.. And it seems that the SMG tranny almost never fails. (Don't think I have read any example of destroyed tranny with these symptoms)
I even read stories about workshops who switched trannys and problem still there.

Actually, the Tranny is more likely to get destroyed in a manual Stick than SMG. With a manual, it is the driver who controls shifting and the chance of destroying something is much bigger.
The SMG does shift faster and many will say harder, but it also is a system which always change gears 100% correct and it is programmed to go in emergency mode when things are not 100% correct.
And that is most likely your problem. The system is "protecting" the tranny because something is out of range when it is shifting gears.
That is whay we get more "problems" with SMG, but in reality these problems with gearshifting are there to protect the tranny from bad shifting which would cause damage to tranny over time. Or even at once.
If you make a mistake on a manual gearbox, there is no program to protect the tranny. So that is why SMG is actually a safer box than the manual.

I understand and agree that smg is better
For tranny.
The system is so complex that diagnosi on
Intermitent failures are not easy.
I have replaced on spring that is located on
Top of gearbox and hold in place by blind plug.
Is there any other spring that could impact
3-4 gear. I know there are others but not
Sure they impact 3-4.
I noticed today that 4-5 is not enganging as
Crisp as used to be. Still fast engagement
But in the past was faster.

Any update VeeM3r? I am having very similar issues in 2, 3, and 4 and was wondering if he was able to fix the problem and what it was? It seems like a compression spring issue. I just had my GPS replaced a few months ago, so I don't think it's that again, as the problem is different (plus no cog light).
