02 1.4Mpi 8 valve, 44 k owned from new, maintained religiously..

 

Couple of years ago we had the coolant light flashing, which went out when the engine warmed up a little and after a restart. Changed the header tank which was quite dirty, all OK for last two years.

 

Now a similar but slightly different problem.

 

As before no coolant loss, level OK, coolant nice and clean, engine running fine, temp gauge steady at mid point when running.

 

As engine warms up and gets close to temperature, say gauge registering ~ 1/4~1/3 the coolant light starts flashing and the fuel gauge within a second or so drops to zero.

 

Have googled and searched on this site, seen a few others have had a similar situation but not seen any pointers as to the solution.

 

From memory, aren't there two sensors which have to read the same and if discrepancy that's when you get a warning light, or am I thinking of another vehicle altogether?

And why the connection with the fuel gauge?

 

Any pointers highly appreciated as it's been a cracker of a runabout and second car. Apart from consumables very little needed to be done. Front console bushes about the biggest non consumable job, done just this year.

 

Cheers.

 

 

Looks like it's the instrument cluster. Arse!
