Hello Tony. Let's try to work out what's going on.
First of all, for a diesel engine temperature gauge to rise above 'normal' is a very serious matter. It indicates that the engine is seriosuly overheating. By the way, I think you mean that the
automatic gearbox went into "limp mode" or, more accurately, "EP" mode which is Emergency Program.

... could 2nd fan speed not be kicking in (it runs when a/c is switched on), is it possible to check it?
|
Tony; when you activate the air conditioning the
slow speed should run continuously. If the fan switches on and off rhythmically, that's the second (fast) speed. So what do you get: continuous running or switching on and off?

Actually, it's at 100°C. Come on T-Cut, you're an old hand on the forum, you should know this by now!

As an emergency measure the failed resistor could be cut out and replaced using heavy gauge wire and good cable connectors.

This is not advisable since the slow speed relay is not rated for the full motor current.

Forget speed 2 Tony. We need to be sure that the slow speed is working. Turn on the ignition with a cold engine and press the windscreen demist button. Is the radiator fan running? Also confirm that your air con. is in working order please.

I have no knowledge of an
engine limp mode.
