Help! Recently, my battery went dead in a couple of days when left off of the charger. Li-ion battery knackered. I've had the scuttle off and found the source of the parasitic drain ( Indicators ) and have cured this. Fully charged, new battery installed, but now the Toad Immobiliser refuses to dis-arm. The red LED just blinks away, but the system doesn't seem to want to recognise the fob. Normally, the ignition light comes on, and the fuel pump primes. Because it's been off of the battery for a few days, could it have lost the codes? Would it have an internal battery keeping the memory alive? Clive
