Cheers all. I'll put the old sender back in and take it back to the garage.

Hi, a bit of advice please. Just after new year while cleaning my Arosa (2004 1.4s) I noticed the coolant level had dropped below minimum. I've had the car from new and never seen it drop. After a bit of a Google, I suspected there might be a leak so decided to take it into the garage. They investigated, couldn't find a leak, but changed the thermostat and coolant. All was well, but a week later I noticed the temp gauge was not moving on my commute to work (~8 miles mostly on dual carriageway). Some further Googling led me to change the temp sender unit, but I lost some coolant in the process and topped it up. Now the gauge moves up to 70 degrees, but never hits the 90 mark that it has done for the past 10 years. As suggested elsewhere on this forum I've run the engine with the expansion unit top/ filler cap off and the in-car temp whacked up full for 4/5 minutes and the gauge didn't move and the fan on the radiator doesn't seem to come on. Any ideas what the problem might be? Cheers.
