[redcupraboy]

Get it hooked up to VAG.COM mate or you could be wasting your time just swapping things over and process of elimination. Is the top of your coolant sensor green as the newer superceded ones are.And get some pics up of your new car

 

[tommy2008cupra]

Low coolant level first of all.

Then bad header tank sensor, or coolant temp sensor.

Low coolant level first of all.

Then bad header tank sensor, or coolant temp sensor.

i would say low coolant level. is first port of call. mine did it the other day. it was a cold morning and when a little heat warmed the system it went off. topped it up that night and next morning it was fine

Does the temp needle go into the high temperatures?
If so, check your coolant level, if its boiling over its most probably the waterpump.

When mine went it was the temp sensor. Cheep quick easy job to sort it.

my light came on on Sunday, 3 beeps and light flashing (light in temp dial)

scared the **** outta me as I'm new to Mk3 ownership and I thought it was an oil light.

checked oil & fluids, everything ok so assume its the sensor. Once warmed up, light stopped flashing, and has been fine since (touch wood)

thing is the temprature here plummeted to -3ish on Saturday night so think it was just the sensor.

just something to keep an eye on (like everything else on a mk3)

Get some pics up mate and start a readers ride! Mine did this and it was low coolant. When you going to get the hybrid done? This christmas has bled me dry so you will probably have your hybrid on before me, even though mines sat in my room!

 

[daves ibiza]

yeah i will mate. im guna try and scratch all the crap off and see if it works or if not ill buy new ect.

 

[andycupra]

its the coolant level sensor.
when cold the coolant level is lower and the sensor appears to be less efficient.
Top it up so that the coolant when cold is near the top end of the ok range, (will be above max when hot, this is ok as its just expansion).

If this fails, try discconnecting the electrical lead in the expansion tank and clean contacts.
