I've noticed lately after drivin for 30 mins+ that every now & again my temp. guage zero's off, then gradually back up to where it should be (I think). I've talked to dealer about it & paid $AU50 for them to "check it out". They told me every thing was fine but if i wanted to replace temp sensing unit it would cost me $AU140 + labour... with no Guarantee if it will fix the problem.

My civic has 120,000 KM's (74556 Miles) has always been factory serviced & never had any problems with it.

Any ideas / solutions would be extremely helpful.

Thanx
