Hello,
Kind of stuck with this one and just looking for some help or pointers if anyone has had a problem relative to this, the car is a DS7 2018 1.6 performance line+ petrol 225.
3 weeks ago the car broke down and we had to get RAC to recover who got it working but with a P306D engine fault still there, he swapped coil packs 1 & 4 and car ran fine, I brought it to a garage anyway who advised it was the spark plugs causing the issue, so they gave the car a service and new spark plugs.
I took the car back and later that weekend I parked the car up where I take my daughter dancing, I noticed the fans were running when I switched it off (unusual) when I came back to start the car, it was dead, would just flash every possible fault code it could think of on the dash and then just flash infotainment screen, pretty simple it had to be the battery, so I bought a new one and replaced myself, like for like after testing the alternator was charging the battery.
The car fired up not a problem, until after idling for 30 seconds the car started to shake, as if car was misfiring, so I took back to the garage, they changed some coil packs around and had it for a full week and they said it was not missing a beat, until I picked it up and not even 400 yards down the road at a red light (I’m sure I’m just cursed) the car started misfiring again, fast forward 4 days and the garage have replaced all the coil packs and the problem still persists, they don’t know what to do to fix it now as there is 6 fault codes (the exact same ones as when they started) all relative to the same things (so I’m told).
So all in all the car has had a service, new spark plugs and new coil packs.
Just looking for someone who has had this problem and who it may be best to give it to (other than the dealer just yet)
Thank you.
