Hello again, recently got a registered copy of MES so I can now see all the bits and bats going on in the Stilo! A few things have poped up that i'm not 100% sure on. (edited out the bit about solar sensor as it works just needs a lot of light to register, guess the black top is on to make sure it only kicks in in super sunny conditions!)

Firstly the evaporator temp is reading 6548.6 degrees. I'm not a scientist but fairly sure the thing would have melted! I assume that is the reading from a frost sensor and as the 1.9 doesn't have one its just the reading it gets from no voltage into those particular pins? Or is there a sensor on the evaporator that clearly needs replacement.

Onto the proxi align bit. I did a proxy align to get the cruise control light to work on my retro fitted cruise control and that all went fine but the first time I did it it said that the climate control had failed to write. I ran it a second time and it was a success but the system is telling me that a few nodes need EOL Programming (End of Line? not sure what it means). Heres the log from MES

WARNING: This vehicle is properly configured. PROXI Alignment is not needed!
Is there a way to find out what is required for EOL programming? And can it be carried out DIY style?
{My theory with regard to solar sensor (admittedly very unlikely), if it needs some sort of final programming could the sensor be working just not read if that makes sence.}


Finally keys (I know lots of threads-I've been reading them). I just want to confirm I have the correct understanding of how the system works and the ins and outs of getting a spare key (my car came with just 1, blue remote no red and no code card - read up on all of this after getting the car but got it cheap so can't complain too much). Please correct me if I get any of this wrong :worship:

So your car has three codes associated with it; Mechanical for the physical cut of the key, PIN for the immobiliser and the Radio code. Each key has its own fixed 'identity' (certainly for remote keys what about standard) so that the body computer can distinguish between multiple keys. Each time a key is used it has a specific code on it to match with the code the body computer has for that key and everytime the key is used the code on that key is changed (I'm getting my self lost here I hope you're still with me!:confused:).

Is that all correct? I get a bit lost when it comes to how keys are added to the system and how new keys are made for the system. Also this seemingly ignores the immobiliser code which is a clear flaw in my understanding of the system. Or does a specific part of the code given to the key stay constant and is the PIN code?
Apparently you can read all these codes from MES but I can't see where.

If i've missed a thread that has a full break down of how this system works can someone point me to it.

Thanks in advance! (y)
