Mine dropped fully, despite there being 2 months to go till it was year six, I suspect due tax Being knocked out while with a dealer, then a 6 month stint.
The front bumper needs to come off to remove the headlight, this is a bit of a job.
The DRL goes off when the indicator comes on depending on headlights being on or off.
I sometimes get this, not on a cold start, but a minute or so after. Sometimes on a hot start, rarely mid run, I’ll have a look and try the brake clean test.
Seems like a misfire, but none detected and no codes, so an air leak makes sense.
Mine is a late 2017, new screen, but not new gearstick, and the higher output, manual still states 5w40, I do oil every 6000 myself, in between a specialist doing it every 12,000.
You can in the Ghibli, pull the whole assembly down, not just the middle shiny bit and there are 3 lamp holders on the back of the PCB. Not sure what lamp though.
try turning the dash dimmer next to the lightswitch down, fully up causes this and also some of the interior lights to stay on. Mine is quite slow to respond to light conditions though.
Parks (main dealer) have a blue one listed at £153k on 11,000 miles, surely in reach at under £150k as well, which was the first to draw my attention to the tumbling values.
PS4S compared to the PZero (20”)
Don’t skip as bad in the cold on lock
Quieter
Lasting longer
95% of the dry grip
Far better in the damp/cold little difference in summer heavy rain.
PS4S drawbacks? The only tyre my local fitter has not recommended repairing, sidewalls are apparently super thin...
