DANGER???Fuel filter light on & zero temp gauge

<< < (2/2)

Hi guys,
Thanks for all this. I found out from the manual that the fuel filter is OK as in, when at startup it lights, it is just for a test. You are right with the water comment.
I was more alarmed with the temperature gauge though, as the manual says that once it goes too hot I should Urgently stop. The dfference is, when I drive and all is well,  the temp is normal and then, suddenly, it drops off to no indication and the temp gauge light goes red.

When I switch the engine off and then back on, the temp is fine. It does not gradually increase and does not increase to top temperature either.

Any idea ?

>>>ECU may be in a limp mode.....

What does this mean :?  Is this dangerous and do you know if this is fixed on the spot by any garage or if I have to go to a LR service station???

spy:
My ppor understanding is that it is what it says on the tin, a way to get you home.   Often faulty auto boxes go ito limp home and its like driving in 3rd gear, no changes and poor response.  

I would imagine that it probably wants either a decent auto electrician or a garage with some diagnostic equipment.  

Maybe I am wrong, in which case I am sure someone will correct me soon!  

Cheers,

Mike

3 beeps/bongs/chimes at startup is the ABS self-test, nothing to worry about (normally !), it seems to be a random test, as both my Td5's have sometimes done the beeps, sometimes not.

Fuel filter warning light - as has already been mentioned, it's probably water in the diesel, or the sensor could be knackered. The light should come on at startup, and then go off - if it comes on whilst driving, then the filter need draining, an easy 5 min job.

Poor response - if it's an auto, then hey, that's life, they all do that !!!, but the temperature gauge hitting the floor.....bizzarre, must be an electrical problem (or a knacked thermostat ?) - best get it checked, I wouldn't fancy doing 500 miles in a Td5 with a suspect cooling system  :shock:

And if the coolant sensor is an input to the engine ECU (or is often the case an output from it) then it may indicate a problem.

Best way to sort is a local independant with access to Rovacom or the like.  You can have your own copy for about £700 including the software codes for a couple of modules, just add laptop.
