I think you'll find the modules are one time only coded. I don't think a second hand unit will work. I replaced my unit with a new one and it fixed it.

So am I right in saying that if I buy this VAG COM thing then I'll be able to turn off bits within that module? Or will it just tell me information about it?

I've put a Snap-On diagnostic tool on it but found nothing. :(

] I've checked all the obvious stuff such as lights and stuff and I've checked the radio. Pulled fuses and done ammeter checks, nothing draws 0.3 amps from the fuse box but removing a fuse takes the drain away by turning off that convience unit.

Thanks for your reply, yes I did mean the convenience unit. The answer is yes to all those questions, however I did notice that having the bonnet open made no difference to the light on the dash (stays off), it certainly looks as though it has a switch on the bonnet lock, I've tried tricking it but it made no difference. One thing I did note was that the drain went down to 0.2 Amps with the doors locked however I'm pretty sure my model doesn't have an alarm, I can't find an alarm horn anywhere. I tried to set the alarm off (just incase it does have one but I can't find it) by locking the car and opening the boot, the light came on in the dash and the flashing red light remained on top of the driver's door card, however there was no alarm sound. I'm very confused.

Hey people, I've got a 51 Skoda Octavia 1.9 TDI Ambiente, I've got a drain on the battery of 0.3 Amps which obviously flattens the battery quite quickly. All I know is; if I take the comfort control module (behind the dash) out before the ignition is turned on the drain goes down to 0.01 Amp which is acceptable, if I take the box out after the ignition has been turned on then the drain stays until you disconnect the battery and reconnect it. I've tried the pulling fuses technique, the drain goes with one of the fuses so I traced the wire and found it leads to the plug connecting to the comfort control module and I'm effectively turning the box off by pulling the fuse (it keeps the drain if you pull the fuse whilst ignition is on - same as removing the box). None of the other fuses make any difference. I've also tried pulling all the relays, made no difference. I tested current across the fuse which controls the module, it wasn't much, something like 0.01 Amps (not the 0.3 Amps I was expecting) I've pulled out all the lights inside the car (which all work) , removed the electric windows isolator (which all worked) , all the door and boot locks work fine but can't disconnect them easily. I've probed just about everything I can think of and now I'm out of ideas, PLEASE HELP! The only thing I can think of is the comfort control module is turning something on and not turning it off properly but I don't want to replace it without knowing for sure. Any help of any sort would be greatly appreciated, thank you in advance.
