2011 Peugeot 508 Cold start interesting sound - 508

Hello

A sound and jerky operation started to appear in my vehicle, as in the video I uploaded in cold start for the last 1 month. After 15-20 minutes, I guess it stops when the lubrication starts or the engine starts to warm up. In addition, if the vehicle is in D position and the air conditioner is on while waiting at the traffic lights, the vehicle started to vibrate too much. Any solution or idea?

Hello my advice

1-replace spark plugs first.

2-What is the engine oil level and what brand of oil do you use for the vehicle

Hello sir

Today the spark plugs were changed, the oil was checked, but the noise continues when the engine is cold.

I said that the spark plugs started to burn from the porcelain parts, this is the problem, but there was no change. Castrol magnatec is always used as oil.

Your oil may be fake. Unfortunately, castrol is the most counterfeited oil on the market.

The reason for the vibration may be the engine mounts. When the air conditioner is on and in the d position, it will be more jerky because the vehicle is loaded. Engine and transmission ears absorb this.

Sounds like an accessory belt tensioner problem to me. It is sold as a set of 2 pieces, one on the top and one on the bottom. Don't worry that the link says hdi, it is used in all models.

Hello, I haven't written for a long time, the engine top cover has changed, it was said that the upper left belt of the engine was broken and it was changed with the wedge just below it. The alternator was overhauled, the tensioner bearing and belt were changed. All fluid and filter changes and maintenance and all of the above repairs were done at the Peugeot service center of my Aegean Aegean Sea. Now the problems are as follows;

While the vehicle is in D position in the Lights, the vehicle continues to vibrate when the air conditioner, heater, etc. is turned on. Even if I press the window open button momentarily, it vibrates. Service comment is no problem.
While the vehicle accelerates on steep slopes, it gradually rises. It's like it's momentarily cut off. We tested the service comment and there is no problem.
It is true that the steering wheel of the vehicle gets harder as the speed increases, but it was very soft before when parking or slowing down, now it started to force a lot during hard par. I'm in trouble with the service comment.

Hello again, my steering problem has finally been resolved. A professional service specializing in steering repair checked it, and they all agreed that this stiffness was normal. However, I felt there was a stiffness, so I continued to investigate. The electric steering pump, tie rod ends, ball joints, and steering box were checked, but they were all confirmed to be fine. However, no one thought to check the tire pressure. The company I bought the tires from said the tire pressure should be 32 bar, so I've always kept it at 32 bar since the day I bought it. However, as the plate inside the car says, when I increased the pressure to 2.5 psi, which is 36 bar, the steering wheel became smooth. I can't understand how we overlooked this. Anyway, the stiffness has finally disappeared. Regarding the other blowing sound when first starting, we are considering the possibility that the balance was incorrect after the turbo overhaul. The turbo will probably be overhauled again and checked. I will continue to update. The vibration continues despite everything I've changed due to the air conditioning shaking while waiting at traffic lights in D. I've become close friends with the mechanics after going to authorized service centers, but they still tell me that this vibration is normal because the car is still under load in D mode, where it's running on gasoline, and that I shouldn't worry about it. Regarding the blowing noise during cold starts, we're considering the possibility that it might be due to improper balancing after the turbo overhaul. I'll have it disassembled again and send it in for inspection and overhaul.
