I found this if it's any help: DIFFLOCK - TDi Timing Tool Kit There's instructions too, which may give you a clue...

The pdf workshop manual I have seems to anticipate a certain reluctance: "Remove pulley, if necessary using extractor LRT-12-409 with thrust pad from LRT-12-031". I haven't had to do it myself yet, so can't offer an alternative I'm afraid... Good luck. Hub.

Can anyone tell me what these two plugs in the engine bay are for please? The first one is under the windscreen in front of the driver and the other is close by, just above the front wheel arch. Thanks fellas.

Before I take my new Disco to bits, has a blanking plate already been fitted with the egr left in place?

It's a '98 - see my signature. Like Clean said on Page 1 - the ratio selector is just like an old 4-speed gear box with a neutral position: from neutral, left/forward is low lock, left/backwards is high lock, right forward is low no-lock and right/backwards is high no-lock. And as James said...

:D Well the bloke that sold me it certainly didn't know much about it, but I think I've been lucky with the car despite that. I've asked him to send me a manual, but he's been stalling, so I guess I'll just get one from somewhere else. Still, I have now figured it out, so thanks fellas. And...

Hey Biglad, I bought my Disco without a manual too and was told that difflock was engaged when low ratio was engaged i.e that the ratio selection lever only moved forwards and backwards (it's bloody stiff too!). Is my 300 different to Snow's 200, or should I also have a left movement to engage...

I'm using Mozilla and IE and neither of them work. I've even exempted the website in my internet security program and still no good - I get the same message as above. Hub.

Did you get sorted out in the end robint? Same thing happened to me and I eventually found that by pressing and holding the BND (Band) button, the words 'CODE IN' popped-up and I could enter the code. Now works fine :)
