2006 Discovery 3 TDV6 GS Auto Stornoway Grey

Pretty sure my WFH isn't working - should I get a warning?

So, I've started the car under 5 degrees with plenty of fuel but no tell tale smoke as far as I could see and the car took an age to heat whilst driving around town so sure it's not working.

Would there normally be an engine mgmt light? I have a D3 MY07 and it gives me lights and bongs for everything else so surprised I didn't get a warning/dash light?

Thanks
Mike

2007 Discovery 3 TDV6 SE Manual Zermatt Silver

AS I understand it, very early D3's had a dash light to show the FBH was on, but that was deleted about 2006?
No warnings on a 2007 AFAIK Richard

That'll explain it then thanks

I suppose I'd better get it fixed at some point then. I've heard it's often just easier to get a garage to replace for another one....I don't intend on doing any spannering myself....any thoughts?

Hi Mike.

If you do fancy having a look at it yourself, you can have this.....

Click image to enlarge

You just need download the Webasto diagnostic software & connect directly to the fbh.
Plenty of information around (if you have the time & patience).
