Hi, I’m Pawel, I’m an overall a pretty happy owner of DS4 e-tense. I love the car, feel that it suits me very much, love it.
But there’s two things that bother me that since yesterday bug me a little more.
First one is minor - phone disconnects from the Bluetooth quite often. Not everyday, but often enough to bother me (it stays on then all of a sudden disconnects and does not connect back until I stop and stay idle for a bit).
Second since yesterday bothers me a lot, enough to ask on the forum if it’s the same experience for everyone. So I had my first warranty check-up and got a replacement Citroën C5 Cross. I noticed the lane assist in that thing works rather excellent - helps me stay perfectly in the middle of my lane - while my DS4 works like a drunk driver, only when I start crossing lines it decides to intervene. So rather than making micro-corrections all the time, it does it rarely but less micro. It works very differently to any car with that function that I drove previously - including that Citroën which I assumed would share the system with (as they share many parts).
Is that your experience too? Or should I take it to the service to have it checked?
Hi.
I have no issues with my bluetooth using Samsung Galaxy S21 Fe 5G and DS4 from 2022.
About lane Assist it works that way except if You have Drive Assist then if You activate it - it is one of the cruise control modes - it will stay in lane center and turn in gentle corners.
Its useful in motorways / autobahn.
I actually think that the DS4 has a quite subtle lane assist compared to both Volvo and VW, Skoda, Cupra.
It most often softly corrects the line, in some cases when it gets confused by missing lane markings it can be a little bit intrusive.
Comparing it to the Kamikaze lane assist of the other cars the DS4 really shines
AvatarPL is correct, you can see the different modes in your display also, when in “full” drive assist mode both the lane markings and the steering wheel turns green in the display, after roughly 10 seconds if not touching (giving feedback) to the steering wheel you’ll get a warning.
I can remember in Stellantis documents from 2021 that it was pointed that Drive Assist 2.0 should be available later via OTA to any DS4 already equipped with Drive Assist + rear detection pack.
Any infos how we can get Drive Assist 2.0? My June 2022 is equipped with all the necessary hardware to execute this. I have noticed in the DS saloon that 2023 model has separate option with info graphics to turn on Drive Assist 2.0 while Drive Assist 1.0 doesn’t have this kind of animation/graphics.
I have both, a DS4 and a C5 Aircross. The DS4 only has in standard lane assist, while the C5 Aircross has lane assist and as an option highway assist. The latter only keeps the car centered in the lane, but you have to activate it along with the cruise control. It then looks like semi-autonomous driving. The car even negotiates gentle curves on its own and you don’t have to hold the steering wheel (to the first alarm - usually after 1 min.)
Of course, the DS4 also has DriverAssist and DriverAssist 2.0, but I haven’t used them yet, so I can’t describe my impressions.
On my drive from collecting my DS4 (2022) I had a reasonably long drive and got used to the normal lane asssit - which felt ok most of the time, but agree that sometimes it did seem to be yanking on the steering wheel a bit more than I would like (e.g. if cutting a corner at speed - of course with good visibility to do so).
On the motorway, I accidentally engaged the Driver Assist - and was amazed at it steering through the bends and staying in lane, very smooth. I quickly turned it off - after I got the warning to KEEP YOUR HANDS ON THE STEERING WHEEL!!
You need two (DriveAssist) or four (DriveAssist 2.0) Bosch Gen 5 corners radars. Definitely are two of them under the back bumper if you have SAM (blind spot alarm in side mirrors) and LCA (reversing alarm - approaching people and cars)
But that’s just the hardware.
Besides, you have to change the VSM1 and IVI_head unit settings, and that’s a real hassle. A DS technician won’t do that. They can only program the VSM or IVI as it was done at the factory, meaning with or without DriveAssist. They lied to you because changing from DA to DA2.0 is also a hardware change.
I’m working on such a change, so maybe I’ll be able to write more on this topic soon.
thank you Andrew for all this info. Yes my DS has SAM and LCA that’s why I was wondering. So now it is only necessary to do this complicated software thing?
I don’t think that’s possible if you only have corner radars at the rear. Two are sufficient for SAMs and LCAs.
Those were just promises from DS. The reality is different, as two more corner radars at the front are needed for DA 2.0.
But how to know if they are also in front? I do have 360 camera, road sign recognition, beside normal front sensors, I also have sensors for lower obstacles, my steering wheel has grip sensor and also car can turn on curves without my hands on, and there is collision risk warning which I can set to close, medim, far.
I found this in my car’s build sheet:
OBSTACLE DETECTION SYSTEM FRONT/REAR RADAR OBSTACLE DETECTOR + TRAJECTORY
Let me put it another way: You fell for it, and that’s it. I don’t know of any instance where something like this was possible, because they tested DriveAssist 2.0 still in 2022. You can see that in the attachment. Front corner radars weren’t available in your model year because this system had not been developed yet.
To get it working for you, you’ll need to replace the front bumper harness and add two corner radars. Then you’ll need to reprogram the VSM and IVI_head_unit, which isn’t always possible. The IVI may need to be replaced after this procedure. Overall, I don’t recommend it.
This bumper is from a factory test car that was never sold. The release date on the radar is 2022. The visible red wires are for the reading sensors in testing Drive Assist 2.0. They are not found in a standard car.
thank you for the explanation
