2025 Nissan primstar / renault traffic / vauxhall vivaro diagnostics
So fellas/ladies have launch diag already plus access to other diagnostic machines. Had van in during the week can read all the on board computers except ecu. Van came in with suspected injector problems. My diagnostic says ecu not equipped. Went old school epbd nothing there other than milage and and vintage number. Used a Autel reader and it was able to pull fault codes (glow plugs) but coudnt tell us anything more. Used another reader cant remember the name it wudnt recognise anything. Then old school machine again eobd was able to get fault codes (also glow plugs) and also some live data. Egr out of range, fuel pressure out of range, maf out of range. After google search looks like you have to get tokens from renault because of a gateway block? Van is nissan primestar. Renault running gear ect. Tried diagnostic tools in renault menus, nissan menus & opel/ vauxhall menus with not much joy. Experience says injector failing but never had this before with diagnostic tools. Any one similar scenario or came across this before on another manufacturer?

If you are using cheapo amazon/ebay readers you are wasting your time, they are not much use.
Take it to a garage and find the exact fault codes, my dude charges £15, you dont have to go to a main dealer.
If youve found the codes and its saying glow plugs and or injectors then its going to be an expensive run around but I can tell you that before you start replacing these, get the diesel pump looked at. Not the diesel pump in the tank, there's a high pressure injector pump, you can get a new or reconditioned one,- someone i know replaced all his injectors, twice, and spent a load on other crap until someone told him about the high pressure pump, but considering the van is only 12m old I can't see it being injectors, glow plugs or pumps
 
How many miles has it done?
If its quite high, you might be better taking the fuel tank off and having a look inside, if there's a layer of what looks like gold glitter at the bottom, its your high pressure pump, the 'glitter' is fragments of brass from the pump.
It causes the exact symptoms of a failed injector
