This week-end was a blast! Awesome people, nice cars, and a lot of perfect driving roads.
However, on day 2 of the Alpine drive, the Mégane showed it’s anger via a check engine light and a request to check the injection. It doesn’t throw an error code though. A quick Google search told me bad fuel will do that.
I refueled it with 98 octane as soon as available and drove home. Light still on. Disconnecting the battery didn’t help. I bought an injector cleaner and refueled with 100 octane. Hoping it will forget it.
[Edit]
Apparently, it wasn’t the fuel, after driving around for a while with the injector cleaner, the check engine light was still glowing at my face, so I took my parents Crossgolf again (what a great purchase) and my mom took the car to Renault, since my OBD reader didn’t find anything.
They plugged it to their computer, which told them it was a faulty pressure sensor in the air intake. They ordered it, got it in the afternoon, installed it, test drove it for 20 minutes (according to the bill). No more light and 300€ gone.
While I’m happy the car is alright again, there are some points I didn’t get:
- Why does the car tell me to check the Injection if an intake air pressure sensor has an issue?
- Why doesn’t my OBD reader, and also the WAY more expensive computer my dad has (Gutmann Mega Macs) find an error code?
- Why does Renault’s computer find it?
- Why does it take 20 minutes to change a sensor that is on top of a pipe at the front of the car, which doesn’t even require to remove the engine cover?
- How can Renault get away with asking 135€ for the same brand sensor you can get for around 50€ on the net?
- Why does it require a 20 minute test drive when just starting the car would have told them that the light doesn’t go on again?
- Why did my mom give them the ok to do the repair when I could have just paid for the diagnosis, taken the car back and changed the sensor myself?
Anyway. I’m going to an Alpine / Renault Sport event this weekend. Might put a sign on the car.

Italian petrol is generaly pretty bad, but they don’t notice because they basically all drive diesels.
Let’s hope the Megane forgives you, now that you treated it to 100 octane.

Don’t bring your Mégane to Ireland then. Your only fuel choices are green nozzle (95 octane) or black one!

It was the same there, but I think it was more about the general quality of the stuff than the octane rating.

My old 505 never had any problems with fuel, primal diesel FTW

That yellow of your RS is so glorious, I hope it will forget. Probably not.

I love it, especially in the sun, when it’s cloudy it looks a bit like Renault’s “jaune sport” (like the Megane 3 in the picture below) when it’s actually “jaune Sirius” (on the Megane 2).
I did 100km with the system cleaner, not forgotten yet, wait and see

Sirius, that was the color the Spider got often as well, right? Great color. Better than jaune sport !

On the Spider it was called “Jaune sport irisé nacre” code 535
Seems like they had little imagination to name their colors at Renault

Haha, totally. Best name ever, to me, is Anti Establish Mint Poly from the early ‘70's by Ford. Code 2149.

That’s a common thing nowadays, that manufacturer-specific codes are stored. You basically have to use a brand-specific tool, or if it’s multi-brand, one with brand-specific support.

- Why does Renault’s computer find it?
Mybe its able to compare fuel pressure, other engine peramiters to sense one is acting flukey.
- Why does it require a 20 minute test drive when just starting the car would have told them that the light doesn’t go on again?
maybe needs to be at operating temp. or maybe the tech wanted a ride in a sweet hatch

Possible, the other reason could be brand specific codes that generic computers can’t read, as bhtooefr pointed out. Kind of makes sense if you want customers to be forced to come to your dealership. Modern cars are terrible.
Maybe they wanted to be sure so I don’t come back an hour later to rip them a new one. I hope it does’t come back, or I’ll have to invest in stickers to hide the CE light

No, you seriously dont. Just think of all the fun Twingo tamer had with his bike.

The hot new thing in OBD technology is permanent codes. I accidentally started my car with the MAF disconnected and my OBD reader couldn’t clear it and a battery pull couldn’t clear it. I had to drive it for a while before the computer was happy.
