Renault Trafic 2015 issues after key programming

**comizelu** · 29th September, 2021, 04:43 PM

Hi members,
I have this problem.. I been called out for a spare key on this van,done plenty even AKL so no problems.
Connected Autel,had pin,programmed spare but it wouldn't program the original back in.
I'm uch error "dongle" and car doesn't crank.
Contacted Autel, they've said you had wrong pin.
Gave me the right pin and programmed the original key back in but still car wouldn't crank.
Pretty sure the uch flash is corrupted.
Can someone give me a virgin flash for this car or any advice?

Thanks

Not a great advert for Autel

Hope you can repair as far as know can't be eeprom'ed, and not aware of any software for other than key programming.
Good luck

The problem is that even the dealership don't have uch, is back order so can take more then a month to get it.
Tomorrow is going to dealership,maybe they can do update on uch(still has communication) and resync everything.
If it works will be great otherwise will try to get uch,reset and program.
If still doesn't work then ECU kit but still abs problems..

Long shot try unpluging ABS.

5 min job for dealership to resync everything, nothing big to worry about. The towing should be more expensive

I know it's 5mins job for them.
The problem is that the uch flash might be corrupted.
Will see tomorrow.

I'll see what dealer can do first.

I know it can reset the pin but don't know about vin

If you use add key function , write back original file ( first step : 20 minutes reading flash !!! )
If you use AKL , BCM is definitely corrupted , like ZedFul bug !!!! For win 20 minutes crappy tool made lose one week !!!
sorry you need to go on dealer or buy an "ecu kit"

100£/ month
but you need to be formed by Renault ( 5-10 k£) for full access function & ECU programming

when abrites first released there software when new , first job and it killed a 2015 traffic , dongle error , remote works but van deceased . the customer recovered it to renault and as he had an original key they reflashed uch and all back to life without issues and only charged £65 plus vat and did it in 20 minutes.

abrites then worked on and fixed the software bug .

abrites is now my 3rd choice tool on these ,and autel 4th choice , 1st choice is smart pro which is the safest of the lot on these , 2nd choice is TDB1000 as they have patch files to recover the uch but tdb only does spares at present.

dealer should sort it with reflash if you have an original key still

Sorry , but if you read flash with an working key , if any problem come , you just write back this flash !!!!
Any tool can write back ! free AVDI ( not use RR019 to add key ) , LONSDOR , OBDSTAR , TDB 1000 .
But if you use 5 minutes method , & if "dongle fault" , only Renault.net can repair BCM , all tool in the world are unable to repair this "dongle fault"

I use only free AVDI + 13.5V , i already kill lot of BCM in BOOT MODE ( never DONGLE FAULT ) during write flash or lose WIFI , i write back "backup flash" and all happy ending , with RR019 for AKL SITUATION , i never had problem on Trafic 3 & Twingo 3 : 5 minutes job without 13.5V .

This car is an risky job , use 13.5 V , do this job in proximity of Renault main dealer ....

I am with Terminator on this one. your UCH might be just in Bootloader mode just rewrite original dump and read pin and program keys again with original key first and you should all be set to go and always use battery maintainer for maintaining proper voltage for flashing on this vehicle. Had a couple gone wrong while reading pin, but just write back the backup and all is good. Worked everytime. Never had this dongle issue before.

Dealer says they can't help..
What's in the ECU kit?
Clocks,ECU,uch,airbag, abs pump?
Any idea?
Thanks
