What to do if the Citroen C5 has a loud engine in the car

First of all, check the cause of the loud sound and rule out the fault of the device itself; Then check the sound insulation between the cockpit and the engine compartment for damage; Finally, consider redoing the engine compartment soundproofing. However, this phenomenon of C5 is quite common, but I don't know how loud your voice is.

Check the cause of the loud sound first. But; Then check whether the sound insulation between the cockpit and the engine compartment is damaged, but I don't know how loud your sound is, and rule out the fault of the equipment itself; Finally, consider redoing the engine compartment sound insulation, C5 This phenomenon is quite common.

There is no question of the size of the voice, only the question of whether it is good or not. What does it mean to be "loud"? Compare it with whom? By ear? It feels like it's never been a reliable thing.

Low-end car, definitely loud.

When the engine is just started, the abnormal noise is obvious, and it is obviously much better after a while, and there is no abnormal sound when it starts again in a short time after the ignition is turned off, what is the problem? When the engine is just started, the abnormal noise is obvious, and it is obviously much better after a while, and there is no abnormal sound when it starts again in a short time after the ignition is turned off, what is the problem? Abnormal engine noise, which can be roughly divided into cold start.

The engine is abnormal when accelerating, and the engine is abnormal when idling. 1. Abnormal noise caused by aging or loosening of the machine foot pad. The foot pad, also known as the chicken paw pad and the tripod, is generally installed in the middle of the engine and the body, connecting the body and the engine, and playing the role of fixing the engine.

And its most important role is to play the effect of cushioning and shock absorption. Once the foot pad is aged or loose, the engine shakes badly, from the cold start is noisy, this is normal Is it time to maintain, check the oil The cold car may be the sound of the valve, this is Citroen.

The genetics, if the valve does not sound, the car will be boring I think it is the situation a Thank you for the answer! Then observe first. The clatter sound similar to a tractor is a clattering sound, accompanied by a slight tremor of the body To add, the second start, there is no noise of either kind, and the effect can be seen for more than one night.

I have the same problem as you, and the car is more than 30,000 kilometers in two years. Recently, there are two kinds of abnormal noises: A will make a clicking sound after starting, feeling that the sound comes from the engine compartment B squeaking after starting, driving more than 20 miles without shouting, and screaming again below 20 miles, running a 2-3 km sound self-healing.

The sound was high-pitched, a bit like tinnitus.

Can't feel the sound coming from**? It's all like this, I also posted a question, there were a few days in winter, and there was a similar fan when accelerating after starting.

The sound of the fan blade scraping the outer cover healed itself. Two days ago, I started and finally heard the legendary tractor-like panting, which has not been noticeable for the past two days. Anyway, I use the car every day, and it's basically okay, but there will be an abnormal sound when I put it in the basement for a few days and then start it.

The sound is not too obvious, it should be fine, I understand that the posture judgment may be put for a long time oil lubrication or heating three-way catalysis as some riders say.

Or what is the question of the exhaust valve. So don't bother with it if it's not particularly obvious, after all, it's good if the car is hot. You look at something else, my colleague bought a Buick last year.

Valeant, that start the return rate is absolutely leveraged, after the start of the automatic throttle, the sound is super loud, he all kinds of check forums to cover up, said axela Angkesai Rabi it is also out of warranty?? There is an abnormal sound when the cold car starts, is it a clattering sound, or what is the sound, in this case, the car is finally thrown into the 4S store, thrown overnight, and let them listen to it the next day. The noise of the cold car starting the engine must be relatively louder, and there is generally no macro rush problem.

If it is obvious, the owner of the building describes what kind of abnormal noise. @2019

In addition, the material of the piston and cylinder block will also have an impact on the sound, if the two are of the same material, such as aluminum alloy or cast iron, the sound is relatively small or basically none; If the piston is made of aluminum alloy and the cylinder block is cast iron, this sound is more common.

10 years Citroen C5, cool car hitting, like the sound of a diesel engine.

Citroen C5 engine like a diesel engine sounds like a three-way catalytic converter is broken, clogged and needs to be replaced, because the exhaust pipe is broken, there is that kind of Shimingqing beep noise.

Is the three-way catalytic converter dismantled?

Is it a three-way catalytic converter, removed from it, just like the sound of a diesel engine.

Kiss to your expansion such as be accompanied: Citroen C5 luxury in the appearance of the modeling, the overall is still relatively atmospheric, and, it is still a more decent design, but also caters to the beauty of the consumer group, and from the side, the body size of this car is 4825 1860 1480mm, the wheelbase is 2815mm, the brand of tires is Michelin, the standard size of front and rear tires are 225 55R17, which is a compact model, But the wheelbase is very long is a standard family car with a radical space, the rear row of this car is equipped with air outlets and other configurations, the rear space is spacious, the rear seat cushion is wide and soft, the layout design of the door handle is very homely, this car is equipped with a turbocharged engine with imitation lead, Zui high power 167 horsepower, Zui high torque 245 Nm, fuel added 92 gasoline, while the gearbox uses a 6AT gearbox, is a very good car.

In fact, if you go to the exhaust pipe in the back and listen to it, you can feel the sound from the exhaust pipe. If the engine is broken, it will be a high-pitched sound.

And if you have a problem with the engine, you won't be able to run, and you will clearly feel that the car is driving wrong.

That's for sure, without a three-way catalytic car, the sound is dull.
