Renault are helpful as always, in their operations manual they say that if the Adblue 0km and service light indicate due to not topping up (and engine won't start), contact main dealer..... does sound as though would need to plug in a Renault Clip to reset.

A long shot but can't see it will do any harm..... reset service light procedure...generally for reminders such as Oil Change Due.... but if it resets the service light, may allow the system to reset as though topped up from 0.
Reset service light indicator Renault Trafic. From year: 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012.


How to reset service light indicator Renault Trafic.

1. Switch ON the Ignition, but don’t start the vehicle.
2. Within 100 seconds of turning the key, push & hold down the accelerator pedal.
3. While still holding down the gas pedal, push and release the brake pedal twice, then press it a 3rd time and hold it down.
4. Release brake and accelerator pedals.
5. Within about ten seconds, the Oil Service maintenance light should turn off.
6. Now turn ignition OFF, then within 3 seconds switch it back to ON position.
7. Switch ignition back OFF to complete.

If it does start off the key, leave it running for at least 10 seconds before moving the vehicle...gives system chance to catch up.

 

Open drivers door, see that sticker

Will See if any tech notes are available for this.

Hi...just an update....I tried the service light reset as suggested but no luck. I then spoke to Renault specialist who has all the latest diagnostic equipment who says he doesn't think he will be able to do it and go main dealer.

I then spoke to the main dealer, who said it needs to come in. In the 1st instance they will attempt to reactivate the adblue system in the ecu. If it fails to do it then the pump may be seized so they will then replace pump. Then if that fails they will replace the adblue ecu which I'm guessing is going to be at great cost.

However, the customer informed me today that the vehicle is still under warranty. Now I know the non-filling up of the adblue is a driver error, however as I previously mentioned the reason it wasn't filled is because the instrument cluster has failed and they couldn't see the messages. I will be pushing for dealer to cover all costs under warranty and fix the instrument cluster and adblue fault. What do people think? Seems reasonable to me lol

 

worth a try, they can only say no, then he can throw at them the dash failed so how would he know

 

Worth asking.... but.....
Had he reported the dash fail to Renault??

If yes and they had the opportunity to fix then to me the logic and warrantee claim stand.
If no, then there is this nasty legal term called contributory negligence which added to another called consequential losses would likely get a loud raspberry and equally large bill.

Please let us know outcome.... I have come across the dealer reset before anecdotally but never seen any details.... pump and adblue CU possibly dead is frightening..... but I do wonder of this is similar to the dealer habit with the older style Electronic Parking Brake systems where they would swap the lot for want of a cable?
