I have a yearly appointment (pretty much every November/December) at my friendly Renault Dealer to swap the Oxygen (Lambda) Sensor on my 2016 Talisman 1.6l dCi 130, doesnt matter if i drove 10k or 30k km.
Currently on my 5th sensor in 115000km and i usually drive 30-40km per trip, very rarely short trips.
According to them, the engine and mixture is fine, but this particular model (1.6l) likes to kill probes, especially when its getting cold, and there is nothing i could really do.
They recommended trying higher quality diesel (usually refueling at JET and OMV), because JET has bad quality and trying diesel cleaner additive every year in addition to the regular filter swap every 60k km.
So my would cost me per year:
• ~350€ new sensor
• ~150€ better brand fuel + additive
• ~500€ performance diesel
2 and 3 will not necessarily extrend the probes life by much.
Has anyone experience with such an issue and are there really no other options other than to get rid of the car?
I like this answer. Diesels definitely take longer to warm up and make more soot when they’re cold.
Another thing to try is to turn the key to “on” but do not start the engine for 10-15 seconds or so. Maybe cycle the key a few times. Heated o2 sensors are, well, heated, so if you can preheat the o2 sensors before starting the engine that might help too
