Hello everyone,
I thought I would introduce myself and share my experience so far with my DS 4, as well as ask a few questions.
About two months ago, I purchased a 2021 DS 4 La Première with 78,000 km and the 1.6 PureTech 180 hp engine. The car is very well equipped and, as far as I can tell, it has almost every option except the panoramic sunroof, Night Vision and the Focal Electra sound system. I specifically wanted a petrol car that would be relatively simple, comfortable and efficient for daily use.
Since buying it, I have installed a 70mai T800 dashcam with the 4G module. Later, I also added a 70mai battery pack because the camera was disconnecting far too quickly when the engine was off. Everything is connected through a hardwire kit plugged into the OBD port using an OBD splitter. For the rear camera, I also had to purchase a USB-C extension cable because the original cable was not long enough for the DS 4.
My biggest mistake so far involved the screens. I got tired of constantly cleaning fingerprints from the central display and the Smart Touch screen, so I decided to install matte screen protectors. Unfortunately, I had left the installation kit inside the car in the sun. I successfully installed the protector on the main display, but while installing the one on the Smart Touch screen, I noticed a small piece of dust. I used the dust-removal sticker included in the kit and it left adhesive residue on the screen.
To this day, I have not been able to remove it. I have already tried three different adhesive-removal products purchased on Amazon, without success. At this point I am honestly wondering whether replacing the screen would be easier. I found used Smart Touch units online for around €200–250 from dismantlers, while my DS dealer quoted approximately €700 for a new part including replacement. Has anyone here replaced the Smart Touch screen themselves? Is it a straightforward job, or does the replacement require coding/programming afterward?
Another issue is the driver’s seat heating, which is currently not working. Fortunately, this should be covered under the warranty. However, I also have a question about the ventilated seats. On my car, when I activate seat ventilation, I mostly hear a fairly loud fan noise and only feel a light airflow. Is that normal on the DS 4, or should the cooling effect be stronger?
Finally, the connected services and ChatGPT. I paid for Navigation Connected Plus and ChatGPT, both subscriptions are active and correctly displayed in the MyDS app, but they never became available in the vehicle. The dealership checked the car and says there is no fault with the vehicle and that I simply need to wait. The problem is that I have already been waiting for two months while continuing to pay for services that I still cannot use.
Has anyone experienced similar issues with Connected Services or ChatGPT activation? How long did it take for the services to appear in the car? Did you have to contact DS support directly, or was there another solution?
Thank you in advance for any advice and feedback.
