hello, I have a 2011 model Peugeot 508 1.6 thp eat 6 vehicle. For about 2 years, my steering wheel has been getting stiff from time to time and has been torturing me at the entrances and exits of the parking lot. When I start the tool on the computer, the problem is solved, but after 1-2 days it reappears. Battery and alternator are fine. Especially at night, when the headlights are on, when I turn the steering wheel to the right and left, the headlights dim. Another problem I have is if the vehicle is in D position and the air conditioner is on while waiting at the traffic lights, the vehicle shakes a lot. What could be the reason for this?.

If it's electric steering.
Bad Earth, Alternator or Battery.

If it's hydraulic steering,
be leaning towards bad tensioner on the accessory belt.

What makes you believe the Alternator is ok ?

Another problem I have is if the vehicle is in D position and the air conditioner is on while waiting at the traffic lights

Possibly a bad tensioner on the accessory belt.

Have you run diagnostics ?

The vehicle has a power steering assisted by an electric motor. alternator and battery durability were measured by a specialist electrician with a voltmeter.

Hello again,
The alternator was changed, the tension pulley and bearing were also changed. I bought a new battery but the problem still persists. They are maintained at the official service, especially when I say that there is steering stiffness, but when they check it, they say there is no problem. The steering gets harder as the speed increases, but when I try to approach the parking lot, I really suffer.
Does anyone have any solution suggestions?

This is the only concern now ?

yes, it still vibrates when the car is in D position. In addition, steering stiffness continues to occur as I mentioned.

Have you had proper diagnostics done with Lexia3 or equal device ?

checks are provided at the official peugeot service but I don't know what device they are using. It was done for a test drive and it was said that there was no problem, but I feel that it is hard because I have been using this vehicle for 3 years.

Ok so it's Lexia.

Can you provide a video of the problem and link it here.

When I run the tool for the first time, an interesting sound comes out. Another problem I have is that I actually add the video link below. The service also looked at this, but it was said that there was no problem because this sound did not come while the vehicle was in the service. I will try to add a video about the steering stiffness and the shaking that occurs in the D position when I am available.

I forgot to add the video link.

Lube the colum UJ. Its probably not that, but they can fail and you'd be daft not to eliminate them for the sake of 5 seconds and a can of WD.

Well, that helps

You have air leak, after the MAF, but where....

Try the PCV valve and associated pipework would be first location to look. It can be anywhere on the air intake, but that noise is a leak.

So if not repaired will it cause a big problem? I mean, is it something that I need to look at urgently or it stops after 10-15 seconds anyway. shouldn't I care?

Use more fuel, car miss behaviour, the ECU will adjust (it has trouble because air ratios in the system are wrong, and it shows in fuel trimming it is doing), but likely to be the shudder issue as well. Not drama driving it and not end of the world issue. No drag driving or beating other car(s) of the mark like this from lights, etc...

Won't throw error codes, which is why it might be missed.

When going up a hill, more precisely, when I stop and get up on a long slope, the vehicle gradually increases its speed. do you think this might be the reason? Or is it clutch or transmission related? There is no problem on the straight road. I only feel it when I stop and get up on a hill.

Air leaks are felt mostly on slight inclines, as a pause compared to where you have placed your foot on the accelerator pedal when compared to level ground. While I would not describe this the way you have, I would start with fixing this and seeing if the issue(s) still exist. What you're saying is not inconsistent with a leak, the ECU is having trouble with air quantity in the actual system (due to a leak) vs what it has measured at the MAF, and is adding more fuel to fix the problem.

Being a manual, you may just adjust for it at takeoff and not feel it, like I would with semi-auto and my driving style is told to me as 'aggressive'. I do notice when the go pedal, doesn't.

I will check for related air leaks and share my experiences here. thank you.

Hi, I have checked, but frankly I do not think I have done a very effective visual and manual check. After the turbo revision last year, the hose that goes from the turbo to the air filter was found to be torn and replaced. That's when the noise started.

I am attaching a photo of the changed part. but there is another hose coming out of this part and I noticed a black band on this hose. I think this is probably where the leak is. well, does this piece with the black band do the air leaking thing you call? Is this also an air bearing part?

I also found an idle hose behind the hose with the end closed with a plastic cap. do you know what this is for? I have attached a photo of it. waiting for your comments.
Thank you.

I found out what the idle pipe is for. but I didn't see a comment on whether it needs to be connected to something or whether it needs to be covered with a plastic cap.pipe details are as follows.
