Normally I take my Clio to Renault for a pre contrôle technique service, have them mot it, ready for me to pick up.
This time I was unable to do so and took my car to be mot’d myself. It had a major failure - L’opacite depasse la valeur de reception ou les mesures sont instables’. I went to Renault for advice and I was told to pour a 300mls can of ‘Renault Diesel Injection Cleaner’ into the tank and go for a good run - heat up the engine for 30 minutes or so - to clean out my clogged up diesel engine.
I asked if that was sufficient to satisfy the CT requirement under pollution regulations, and Renault said YES!
However there is no mode d’emploi on this can of additive. Do I pour it into a full tank, a half tank and go for a fast drive…or what?
Grateful for any advice!
