Which reminds me...
I had a trip recently where the immobiliser in my 300 Tdi 'fender umm.... immobilised me.
Permanently. It got confused or something.
As luck would have it I was in a metro area. 8 hours earlier, and I'd probably still be there, dying of thirst (it's Australia after all) with my better half and 2 year old son.
A quick call to an auto-sparkie fixed the problem permanently within the hour. He completely bypassed the immobiliser and now there is absolutely no chance of being stranded in the middle of the desert due to the immobiliser having a fit.
A byproduct is that I can start the beasty without having to have the little dongle-thingy on my keyring.
The chances of my landy being stolen are almost zero. I've only ever met one other blue 97 'fender, so it's just too easy to spot for most thieves (I hope). That and the 'secret switch' installed by the sparky should see me right.
Besides, I'd rather run the risk of it being stolen in a metro area, than it failing to start thousands of kms from home with dwindling water supplies and 40+ deg C temps and no shade...
Seriously folks, if you plan on doing really remote stuff (like the Simpson Desert or something), for the love of god.... please disable your immobiliser. They're dangerous, IMHO. Something to think about...
