When i got a check anti-pollution system warning it was a faulty co2 sensor on the exhaust, replaced by Renault (warranty), but there can be other reasons - hopefully someone will be along soon to tell you how to check the fault code....
Hi all, Same here with a Clio 1.2 Turbo, 2016 that has only 40,000 KM. A couple of days ago both engine light and spanner icon lit up, there is a message saying "check anti pollution system".
1. The car drives as usual.
2. I thought of dirty fuel (as I refueled a day before the message came up) so I've added a 44k additive, no luck.
3. Oil, Oil filter, spark plugs - were replaced about 2000 KM ago
