I'm checking the resistance on abs sensors tomorrow on my 03 td4 as per "royturbodiesels" post. Is it definately ok to disconnect the battery? I did this once on a peogeot I owned and then had to pay to get the engine immobiliser unlocked. Don't want to make a similar mistake.

I had a similar issue once on a 2nd hand car that I didn't have the radio code for!
Sorry I can't be of any help but I'd risk it if it was me.

Before you disconnect set up a feed from another 12v source, you wont loose any settings by doing this. I think you can buy gadgets with a power source that plug in to the cigar lighter socket if you dont want to rig something up.

Read the handbook. All advice is there.
Just make sure you have the radio code. You may also have to recalibrate your electric windows and tailgate.

Hello,
If you are planning to do things which involves you disconnecting the battery a lot then consider one of these: Battery Quick Master Disconnect Isolator Cut Off Switch | eBay
I've got one permanently on the battery. They are very useful...

No point in disconnecting the battery to work on electrics if you are going to keep the systems live from another source. That trick is only suitable when changing the battery.
