Hi guys!
I'm really sorry for my bad english, english is not my native language
Car:
Renault
clio 2
2001
1.2 16v D4FB
BMT N2
long story short
The turn indicator stopped working, we found out that the bmt was faulty. we tried to repair it worked for a little time then died again(but the car atleast started)
we bought a used bmt, put it in, ofc it didn't work because the immo. we called a reno tech, he said the immo should be cloned from the old one. we sent the bmt to him then got it back little later, put it in didn't worked
we called an another guy who work on immos, didn't worked that time either. we bought a renolink watched a few a videos how it worked.
scanned uch
Type: uch Addres: 36 or 38 (i don't remember) Name: ? File: ?
found that a little odd
found out later that at key teaching the sagem bmt the only one that connects
trying to read pin and writes out nothing neither isk neither pin
the transponder teaching works, I can close and open the car
start learning -> put the key in -> put on ignition (nothing shows of on renolink)
but interestingly i can start the car if i do start learning -> validate(without doing anything else) (the red dot on cluster is always glowing)
the car works fine until the battery cable is removed then it forgets something and doesn't start anymore
what i found interesting was that if i try to read the uch "read ecu" then it is connects but it says "nothing to be read"
At the end i think it's only bypassing the need for a key and doesn't even learn it
I tried with the old one too but does the same (the old one had the same problem when we got them back)
