Right I have a little issue with my MK4.

The tempreture gauge likes to fluctuate.

It can be fine all day and then a mile from the house you will get a little hicup, the tempreture with drop to minimum and if you have the cruise turned on that will cut out too. Then again some days the tempreture gauge dosen't move from Minimum or will randomly spurt upto 90 half way home or something. It's totally intermitant.



I thought at first it was a sticky thermostat, but today was the first day I actually got the little hicup and the cruise went off. So it is getting worse.



I went into Test mode and got this DTC 01 C40168



After a google all I could find was this... http://www.talkford.com/topic/94564-fault-code/



So I'm totally at a loss what might be up?

It's going in to be diagnosed tommorow under warrenty (In a halfrauds autocentre which I aint too happy about). But I want to go in with as much info as possible and even whats up with the car so I can just tell them.



Anyone got any ideas?
