Is this an accurate and Major problem?

car had a coolant flush and recall on gearbox seal during the week. when got it back the ev was louder, could hear it whining inside the car. couldn't before.

the lag at around 70km from when the gearbox engages while in ev mode got really bad too. very poor acceleration.

how bad could this be or could it be a symptom of low battery

Need help finding something

Recently I’ve discovered a small puddle of oil in my airbox, I’m assuming it’s due to a blocked PCV valve but for the life of me I cannot find it. It’s on a 2004 Clio 1.2 litre 16 valve. Anyone able to help? Thanks

2016 Renault Fluence: The clutch burnt out after a brake service – limited power on gas

After replacing the brake pads at the service center, a strange problem developed.

The car barely responded when I pressed the gas pedal, severely limiting power (limp mode), but drove normally when I pressed the gas pedal again.

Diagnostics revealed that the brake pedal sensor (the throttle body) had completely burned out.

Apparently, the service center damaged it during work.

I replaced it with a new one (part number 253200005R), adjusted the clearance, and the problem completely disappeared, the throttle response became normal, and the errors disappeared.

If anyone else experiences this problem with limited power after a brake service, check this throttle body first. It's an inexpensive part and can be replaced in 10 minutes.

Has anyone encountered something similar? What errors were returned (P0504, etc.)?

What can be? 1.5 dci CLIO III

Hello, I have a Renault Clio III 1.5 dCi (K9K768) with 306,000 km. I bought it at 300,000 km.

The engine runs very smoothly and seems to have been well maintained by the previous owner. At 303,000 km, I performed a full service (oil, filters, and added Ceratec).

The car does not burn oil and produces no smoke at all.

However, occasionally I notice a metallic-like noise coming from the engine. It doesn’t sound like a constant hard metallic knock, and it only happens sometimes, mainly at idle.

What’s strange is that when I listen directly on top of the engine, I don’t hear it much. But inside the car, the noise is more noticeable.

What could this be? Could it be the injectors, or something else?

1.0 SCe reliability compared to D4F?

Im a big fan of simple NA indirect injection petrol engines, and especially the legendary 1.2 16V D4F. However there isnt a lot of talk about its succesors, the H4D and B4D (the 1.0 SCe). My question is how reliable are they. I doubt they are as bulletproof as the D4F, but do they have any major issues? Also the SCe has a chain, instead of a belt on the 1.2, so how long is the lifespan of the chain (i ask this, because for some reason newer engines with chains, always have a comically low lifespan, almost like a belt).

Megane IV Grandtour outdoor cover

Hi!

As the title states, I'm searching for a good waterproof outdoor cover for my Megane IV Grandtour from 2021. I have seen many generic ones, but I'm sceptic if they will fit correctly, I have had one in the past but that one tore after roughly a year.

Would love to hear your feedback/recommendations!

EDC7 issues

Hey!

I have a problem with my 2019 Scenic 4 1.3 TCe 140 (car bought at around 40,000 km from Renault). It was very minor at first but has been getting worse and worse. The gearbox slips in a completely random way, which makes me think it’s a management issue. Sometimes the car starts perfectly, even uphill, and other times it slips as if the clutch had 200,000 km of city driving on it… even downhill while barely releasing the brakes.

We took it to Renault a few weeks after buying it, and they told us it was the traction control… probably! At the beginning, the problem mostly happened in one place: the entrance to the driveway where the car is parked. To get in, you have to turn the wheel fully and go slowly because it’s tight. Then it started happening elsewhere, but almost always while turning. Now it also happens in a straight line…

The only way to (almost) make sure the gearbox doesn’t slip is to use the accelerator like a clutch pedal. You have to keep very precise pressure to stay between slipping and a starting brutally —like finding a slipping point 😂. The strangest thing is how inconsistent the issue is. Not only is it random, but it also almost completely disappears at times (e.g., perfect throughout February, then comes back in March, but usually for shorter periods, like a week or so).

Another issue at around 80,000 km: engine speed fluctuating by 100–200 rpm in 5th and 7th gears. Perfect in 6th though. We went back to Renault, and they told us the gearbox oil hadn’t been changed after 4 years (or 90,000 km) as recommended—the previous maintenance was done at a multi-brand garage…

Result: double oil change with driving in between, €700, and the issue was fixed. According to them, nothing suspicious (no metal particles).

At the same time as the oil change, Renault reprogrammed the gearbox and the injectors. The problem seemed to improve for a while, but it came back (placebo effect?). Also, the engine became noisier (injector noise, especially when cold), and the gearbox now tends to run at low revs (sometimes down to 1100 rpm while driving), but it also downshifts more easily uphill (sometimes going over 3000 rpm even when unnecessary). Recently, 3rd gear has also become noisier—not a strange noise, the same as other gears, but louder.

Finally, since the beginning, the accelerator pedal has felt quite strange. I don’t know if it’s related to the gearbox, but still. The pedal lacks responsiveness and precision. For example: at the bottom of a hill, I accelerate to avoid slowing down, and nothing (or almost nothing) happens for at least a second, then suddenly the car takes off as if my foot was flat on the floor. Turbo lag could explain the sudden acceleration, but not the initial delay.

Overall, the car is very unpleasant to drive when these issues occur, and I’m quite disappointed with it. The next one will have a good old manual gearbox, and that’ll be just fine!

Renault Austral Boot space

I’m doing a lease on a car on vacation in France. The car is a brand new (2026?) Renault Austral Hybrid Petrol Auto SGHA Hybrid.

I’m trying to get a sense of the boot space. We are travelling with kids so will have two car seats, two large suitcases, two small carry on hard shell suitcases, two yoyo travel prams (they pack down) and a couple of backpacks.

I’m just wondering whether someone who owns this car or an earlier model might be able to shed some light on the boot / back seat space. Specifically whether two large suitcases fit in the boot next to each other.

Thanks very much.
