Hi everyone, I just noticed today that my A4 2.8 Quattro 1998 model, seems to take ages to get to the correct tempatature 90. I was driving mostly in town conditions and a bit of duel carigway aprox 50mph. But it took about 6 miles (20 mins)to get up to temparature. Them i parked up for 25mins then when i drove it again it took about the same again 6 miles (20 mins). Is this normal????? I have had cars before and when the thermostat is gone on the motorway the temp normaly drops, but mine is not doing this. So i presume my thermostat is ok. Also just a point could be linked. I changed the plugs a few days ago, they had been in for aprox 11000 miles. The old plugs were quite black on the ends with a little bit of carbon build up (dont know if this is normal) But i thought it could have been running rich mixture (maybe on choke). I have had the car tested on emisions machine and they told me it was exelent emisions and everything was ok. WHAT DO YOU GUYS THINK! PLEASE GIVE ME SOME ADVICE. (AFTER READING SOMETHING ON THE FORUM I CHECKED THE CAR AGAIN AND IT SEAMS THE RADIATOR COOLING FAN IS ON CONTINUASLY WHEN THE ENGINE IS RUNNING????) WHAT CAN CAUSE THIS HELP NEEDED URGENT.
