Good day to you all,
I'm currently driving a S 100D from late 2017, now with 146 000 km on the odometer, a great car overall.
I started to have supercharge issues last year. A charge would quickly ramp up to 135-142KW, but after a few minutes would start throttle at 100-110KW.
After a service request (and 2 months just for getting the part !), local service center changed the 3 way-valve in January and I thought all was resolved, had no more issues, however I was not supercharging much, perhaps 4-5 times only since, and always in cold weather.
Yesterday during a long trip I started to have these issues again.
1st supercharge starting at 15%, car went up to 140 then start throttling at around 110KW (I was still in the 20%30% range). I could hear the fans starting for a few minutes then stopping then starting again full speed, stopping and so soon. 2nd supercharge starting from 5%, same behaviour or even worse, I was below 100KW before reaching 35%. Normal conditions (temperature outside 13-15°C, on german motorway... but crowded).
I've opened the service mode during this second attempt and I can see several times the same alerts popping up:
- THC_w0145_rfrgSuctPressRange
- THC_w0142_rfrgSuctPress
I guess all of this is linked again to thermal management issues but which ones? I searched a bit on the internet but could not find these error codes anywhere.
I've opened a new service request but will need to travel soon, so if anybody knows what's happening and what I should do to avoid any problem that would be welcome.
