Defender 300 TDI Quirks.

Thought I'd start this thread about the quirks of the Defender, namely the 300 TDI one.

1. Stored Defender for several months, battery disconnected. Reconnect battery, I find the immobilizer isn't doing its job ie I can start the thing with the keys and no need to dongle the immobilizer to get it to start.
After it's connected up for a while the immobilizer decides it is time to work and does its job.

2. Similar story with the heater. Fails to work after a few months stored. Decides to work after being drived about for a few hundred miles.

Post your Quirks and possible solutions below...

Heater, bad / corroded conection. Vibration of driving makes enough of contact to work.

In the huff for deserting it for a few months and just giving you a warning of its abilities to cause trouble if you do it again.

Corrosion/oxidisation on electrical joints/switches. Very common. A good dose of WD40 before leaving it next time might help.

The 300tdi has an immobiliser?

Mine does.
It came with the vehicle when I bought it.
