Replaced the temperature sender, reading are very low!

Hi all,

Had the car a week and have changed the Temp Sender from a Black to a Green one as I was getting the G62 faults on VAG-COM.

Got the replacement Greeny (059-919-501A) from Fleabay and fitted. Two long test drives an dthe temps are showing funny.

Yesterday would go above 75c, today took 10 minutes to rise from 60c, after the same drive and parked outside did it finally got around to getting to 90c.

Is this common for a new sensor to take time to bed in like this or could it be dodgy?

Best,

Whitey

Should read instantly, canyou see what it is doing in vag com? Ifnot just use the climate controls http://lee69.co.uk/Car stuff/Leon/codes.txt

A stuck open thermostat will make the engine take a long time to warm up.

or maybe you have an air lock after changing the sensor.

This afternoon drove to Brighton (15 miles), gauge hardly moved from 60c.
Stopped at a motor factors and the temp started going up again to 75c.
Car only seems to show temp when turned on when warm already (as opposed to letting it cool).

With the old black one, it warmed up fine (or showed that it was).

I had probably a tea-spoons worth of fluid lose on changing the sensor (enough for air lock??), so should I put the old on back in see what that shows and get a replacement greeny....

Could well be a dodgy sender.
