Hello forum friends
I have a question about the idling behavior of my car, a GOLF GTD Mk7, DSG6, MQB from 2016, 45,000 km, Europe.
For some time now I have observed that when I start the car from cold (it always sleeps in the garage), the revolutions remain at 800 - 850 rpm, as always.
When I start driving and stop at a traffic light, the revolutions rise to 1000 rpm, they never go above 1000 rpm, a few seconds later they drop again to 800 - 850 rpm, this behavior is cyclical, that is, when I stop with the foot brake pressed Suddenly the revolutions go up to 1000 rpm, sometimes they go down while I'm stopped and other times they don't.
When I enter the garage to park the revolutions drop again to 800 - 850 rpm, stable.
Normally my daily trip is about 50 km, on the highway, that is, 95% of the trip I take is on the highway, y cuando para en un semaforo, el motor esta caliente despues de circular esos 50 - 60km., ocurre los mismo, las revoluciones suben de 800 - 850 rpm, a 1000 rpm.
I don't have any warnings in the FIS, nor after performing a scan with OBDeleven, there are no errors or failures.
The electrical consumers are the usual ones, Discover Pro Mib2 on, DRL on, and the interior heating of the car at 23 degrees (heats the cabin perfectly), Air conditioning off, the Air conditioning is only usually connected in the summer to cool the car; I don't use Autohold either.
Asked:
Could it be because I have the interior heating turned on at 23 degrees? If I don't turn on the heating, the revolutions remain at 800 - 850 rpm, without variations.
Perhaps the solenoid valve of the primary heating circuit pump influences this behavior, as it is acting to heat up the interior heating circuit...??
I apologize for being long in my comment, but I wanted to explain it in the best way possible.
Thank you so much.
