Hi,
BG can be replaced with N2, HG replaced with N3.
N3 will replace N2.
N1 seems to only like N1
Not complete list but a start.

Thank"s for your input
So if BG can be replace width N?2 why does N?2 have delay after turn key off ?
I mean I switch off the key, and take it out of the ignition, and engine only 4 seconds later shot off ?
Any idea ?
I coded UCH width Clip
Thank"s in advance

Solder all caps etc. under black 40 pin connector. Solves 99% of UCH faults.
Also, for your own reference, from a good UCH measure all components to PCB GND under the connector and write all values down. Will give you an idea if a component or something connected to it is not right. Will save you hassle of removing connector more than once.

Hi,
What I can tell you is I've change about 50 UCHs in my life, most of them with original parts, and a lot with used parts.
You can allaways change Nx for a same grade or higher (N1 instead of BG, N2 instead of N1 etc).
Another speciall thing is if you got a Clio with engine 1,9 DTI, it needs to be the same UCH because of the antitheft. No other UCHs works for antitheft instead of the original: it happens to me twice ( red light stays on without flashing, it means no comunication UCH=>ECU) and I did not find another solution than removing antitheft from ECU 0 281 010 788 .
I've tested virgin, copying, all desperate things you can do.
I think this kind of ECUs have a special protocol.

Hi,
By the way I order an UCH to replace BG P8200065817 G1 V4.1 , the replacement from Renault was 82 00 621 763 written N3 instead of BG.

Hi,
For the same UCH BG P8200065817 G1 V4.1 pulled up from recycle.
Antitheft light blinking permantly, does not reconise or even see any key i tryed (tested reset and another antena etc).
Tested continuity beetwen pin8 Black connector 40 ways and SAGEM E34707A OK (near the same connector upper right side, no contact to earth.
Tryed to replace the chip SAGEM E34707A from another working UCH: Now works fine, can learn the keys again, car starts.

Hi,
Ok tomo, i'll try to follow the electronic circuit to understand.
You don't say which problem this change solves: antitheft light staying on or flashing, etc. Those are for me the biggest problems because many times they are sporadic. The last one i save changing SAGEM E34707A, was permanently inoperative, a kind of breakdown easy to fix.

Problems is
Car does not start,electric window problem, lights dont work etc.
Car going crazy and sometimes when you pull wiring of uch car work ok but this fix this errors.
First is sporadic that car does not start and problem with electric in car but then fail to start after some time.
This fix if car start doing this with no reason.
If someone change batery and reverse polarity mix + and - this is not fix for this.
And if some part inside uch is burn for some reason.

HI there,
Can somebody help me to solve my UCH clio2 problem? I would pay it via paypal, just PM me. (if you can send me a good UCH for the old one)
My wife has a 2001 16v 75LE 1.2 clio2 and the UCH sometimes stoppes the index blinker. Very dangerous(!), my kids are inside the car.
And sometimes the windscreen wipers stops + I hear many relay clicking sounds from the uch box I guess, like an old tram from nineteens.
My UCH is : G1 V4.1 21 658 964 -5b 26/06/01
Reading your prev posts, I see I can change it with an N1, or N3? (the car has no clima and only the first windows are electricals)
Thanks,
tomo776
30th December, 2018, 07:28 PM
Did you try my solution?
If you have soldering skils you can do it.
For change uch you must have virgin dump for uch and ecu and renault clip. Or put new used uch and make new keys and make configiration of uch to match you equipment that you have in car.

Hi, can you send me password to unpack your solution? (i don't know what is it)
What I did today is I resoldered the 40 pin black connector, but got no luck.
When UCH stoppes the wiper, switching on the blinker starts the rear wiper too, all the time despite it is off.
I have OBD immo key overide tool from hickleys.com and I bought some cheep remote controller to control the door lock => I guess my UCH has been in bad condition for years
Can I just replace G1 V4.1 21 658 964 -5b 26/06/01 with a cheap used N2 v4.3 ? My friend is an electrican at Renault saloon in my town, he has tools to reset, copy UCH, and said the new UCH is around 400 british fonts, our car not worth so much.

What can replace N3?
No idea, use stalk function for “Obdmaster” not sure if was posted online or offline
but he was playing with himself and discovered odd things like no headlights or nor windows
if you cant find excact unit you need, get chepest off ebay and/or
”price up new from dealer” ask for latest part numbers
