Hi everyone,
I’m trying to understand if what happened to my car is normal or if the dealership likely changed something electronically/software-wise during a repair.
I own a Renault Megane RS Trophy with EDC gearbox and OPF. The car recently went to Renault for replacement of the high-pressure fuel pump and an electrical relay/control unit.
Before the repair, the car behaved exactly like a normal Megane RS Trophy should in RS/Race mode: very noticeable “farts”/cracks during aggressive EDC upshifts. Anyone familiar with these cars knows this is part of the original character of the car.
Immediately after getting the car back from Renault, the behavior changed dramatically:
- the EDC upshift farts are now extremely muted
- the gearbox sounds much more quiet and filtered
- the car simply does not behave the same way anymore
The dealership claims:
- they only replaced the faulty parts
- they did not intentionally change anything else
- “the car is not supposed to make those noises anyway”
Which honestly makes no sense to me, because:
- the car has always done it
- many stock Megane 4 RS Trophy models do it
- the change happened immediately after the repair
So my question is:
- can Renault automatically push ECU/TCU updates during this type of repair?
- could an ECU calibration/update related to emissions or gearbox behavior reduce the pops/farts?
- has anyone here lost the RS/Race EDC crack/fart behavior after dealer updates?
The car is still completely stock software-wise as far as I know.
Would really appreciate feedback from anyone experienced with Renault Sport cars, CLIP/DDT4All, ECU updates, etc.
