Hello everyone - 1st post.
I belive Ive a mk4 Astra (its a 52 plate)
The digital display of the outside temp has gone haywire. When everyone else was scraping ice off the car the other morning, my display said 69 degrees c !!!
Now its just --.
Any ideas what i can look for. Change the sensor (where is it) or cabling corrosion etc etc.
