Had my Q3 for a month now & I have a problem with the Rad fans running & staying on after shutting the engine down. Did a forced Regen about a week ago, & got the soot level down to 0.52 grams it was 19 grams before regen. Checked again yesterday & calculated was 12.6 grams but measured was 20.2 grams. Don't know if this is normal or not? Sometimes the Fans are on within minutes of cold start ( AC off). Other times they seem to work normally. Temp gauge reads 90C, 85ishC in VCDS & no signs of overheating.
No fault codes in VCDS. I'm guessing it could be a Sensor fault?
Any help greatly appreciated.
