Hello,
Sometimes, the internal combustion engine (ICE) of my 2022 DS-7 E-Tense starts shaking immediately after full acceleration.
At times, the shaking gradually subsides after a few seconds, but other times it doesn’t.
This phenomenon is sometimes accompanied by the engine self-diagnostic light flashing for a few seconds.
I turn off the combustion engine and drive in electric mode for a few minutes; upon restarting, the combustion engine no longer shakes.
The first culprit that came to mind was the spark plugs, but they should still be good for at least another 10,000 km (the last service was done a month ago).
The manual states that this engine self-diagnostic light flashing requires contacting a dealer or a qualified workshop.
I would like to know what kind of fault to expect before taking the car to the dealership.
Please excuse any phrasing errors; English is not my first language.
It does sound like a misfire of some type.
Spar plugs, leads, coil pack, fuel injector fault, fuel starvation.
I would have the car checked for error codes.
@Jactac,
Thanks for the reply.
Manual vehicle test (accessed via the “Check/Diagnostic” button in the Driving/Vehicle touch screen menu) does not indicate errors.
Probably, this self Manual test is not enough.
I dont trust the onboard diagnostic tool.
Recently my car had the engine management light on for a full 3 days , yet the diagnostic tool says no faults found.
Clearly , if the car has sensed an issue and puts up the engine management warning icon, then surely the diagnostic tool must record this fault.
I’m scheduling an appointment for testing (and, if necessary, repairs) and I’ll get back to you.
A funny thing: since I started this thread, even though I’ve pushed hard the car a few times, the issue hasn’t recurred; like it got scared…
The engine management light came on and stayed on for 3 days on my car, then as soon as I contacted the dealership to get it checked out the light went off and has stayed off.
Maybe the dealership can do things remotely just to wind the driver up ![]()
