Greetings from Greece.
I am the owner of a used Ds4 Esprit de Voyage 2023, and since purchasing the vehicle, I noticed that the windshield wipers required replacement. I replaced them shortly after with Bosch Aerotwin blades, selecting the correct dimensions according to the vehicle specifications.
Since the replacement, I have observed the following behavior:
When operating in automatic (rain-sensing) mode during rainy conditions, the wipers slightly lower their position each time they return to the parked position. I understand that a small adjustment in the resting position can be normal, as it may be designed to improve visibility.
However, the issue is that on many occasions the parked position shifts progressively lower than the designated alignment marks on the windshield. During a particularly heavy rain, the wipers moved so low that they made contact with the plastic trim above the hood.
Interestingly, after locking the vehicle, in approximately 8 out of 10 cases, the wipers return to their correct, original marked position.
I do not believe the issue is related to the new wiper blades. Additionally, the wiper arms are secure and do not appear to be loose.
Has anyone experienced a similar situation, or could provide insight into what may be causing this behavior?
My wipers slightly drop when when returning to their home position, but dont touch the plastic tray underneath.

Until now only happened once to me, that the wipers were touching the tray. But again, to drop even slightly from their park position is a bit strange. From the dealer shop they have suggested to buy the original blades (90€) as the after market like Bosch, might not have the exact maker specifications, and that’s why it is affecting the position of the wipers. For me this is the first time
I hear something like that. Bosch is a well known maker in the industry for a good quality wipers, which many car manufactures uses.
Same thing happens on my sons Vauxhall Astra which is the same car dressed differently to the DS.
I see… Did he found the solution on that or at least what is causing this weird behavior.?
No solution sought as we both thought this is normal.
On both our cars the blades sweep as normal when in constant mode, but if they are set for intermittent, they sweep as normal but when stopping in between each sweep they come to a stop and then drop slightly into the home position.
They don’t touch the plastic tray underneath though.
My previous Volvo did the same thing.
Try putting yours on constant sweep, see if they perform as normal (not dropping), and then try them in intermittent mode see if they drop into the home position in between sweeps.
I would say this is normal behaviour ?
As long as they dont make contact with the tray below !
I would of thought theres some type of sensor telling the blades where to stop in the home position, maybe this sensor is faulty on your car causing the arms to drop past the correct home position ?
Do you still have the old blades, could try swapping back to see if the issue is still there, or buy a really cheap set just to try.
Bosch blades though are just as good as the DS manufactured blades if not better.
As you mentioned, during constant operation the wipers work fine. The “issue” only appears when using intermittent mode (either manually or in auto mode). When the wipers return to their normal park position, they often drop slightly below the sweep area.
What is strange is that if I lock the car within a few seconds, the wipers move back and park correctly between the sweeps.
Unfortunately, I no longer have the old blades, so I cannot confirm whether this behavior existed before or if it started after the replacement.
The only time the wipers touched the tray was the very first time they operated after the new blades were installed. Since then, the only issue is that they sometimes return below the sweep area. That’s why I was thinking it might be related to the blades themselves.
My plan is to wait for some time and then evaluate how consistently this happens. Perhaps the blades had been sitting in the box for a long time and became a bit dry or stiff—I’m not sure.
Unfortunately, there is no wiper arm calibration available to reset their normal position. Since the arms are fully secured and not loose, I prefer not to adjust or tamper with them further.
As i mentioned before not even the engineers in the dealershop has a clue or a solution on that.
My previous and present PSA cars had a similar issue, and I don’t consider it a defect. The windshield wiper blades sometimes touch the A-pillar and sometimes make a slight movement when they’re on, but they’re in the rest position.
Normally they shouldn’t touch the A-pillar, neither the plastic tray underneath the windshield. I have seen on the internet that you can adjust that,by setting the wipers to service position (ignition off and hold down the right lever) if they are positioned vertical to the windshield you can slightly adjust them by hand to the exact vertical position and then to restart the car.
By that somehow it is re-learning again the limits. In my case they are vertical on the windshield and not touching the A-pillar, but it didn’t work for the plastic tray underneath the windshield.
