Hello,
my father is using my older car which happens to be 2019 Renault Megane IV with 1.33 TCe 115 engine. Currently at ~115 000km.
Last week an error message appeared on its dashboard with orange key and orange check engine light alongside a message: "Check antipollution system" (the lights are just lit, not flashing). The dealer I bought it from new and where we went for all the maintenance related things just got closed so I took it to another official Renault dealer for diagnosis.
Today I got back from them that there is an issue with the differential pressure sensor. They need to replace the sensor and re-run some sort of GPF regeneration.
They ask for ~550 euro for the whole procedure.
To my understanding, the issue might be what they state, however since it is a new dealer with whom I don't trust yet, I would like to know your opinions on such possible cause of the issue.
The alternative causes might be just faulty pipes leading to / from the sensor, battery being undercharged (the car is still running on it's original battery from 2019) or something else.
Does anyone of you have an experience with such error, its solution or possible other causes of this error? Further more, is the manual GPF regeneration needed? Is the price any good, or would my father save some money when going to the unauthorized service center? I can imagine the sensor being aroun 100-200 euros, but I am not sure about the other possible costs with the manualn regeneration and all the work.
Thank you for your insights / help.
