Battery discharge

[Nomag]

Just wondering if anyone has a had a similar prob to me?
I went away last weekend, car parked on drive from Thursday pm, went to open car Tuesday morning, wouldn't open, soon realised the battery was completely flat. I opened the door with the key, nothing obviously left on.
Called Seat Assist (i.e. the AA) that evening, the AA guy put a booster on the battery and started the car no probs, looked and said he couldn't see anything that had been left on and drained the battery. I never leave the lights on, but even so the have the 'coming home' feature so definitely WAS NOT this.
The guy checked out that the alternator was charging the battery, no probs.
He told me to drive the car for an hour to charge the battery! Humm.
I put my trickle charger on over night, no probs since.
Now, I've checked with my neightbours, the alarm was not going off while we were away. I've booked it in with the dealer to have a look, but I don't have any confidence they will find anything. I'm just puzzled as to what could possibly have drained the battery, as I say fine ever since.
The only accessory I have fitted is a Parrot bluetooth kit, and that is ignition live only.
Anyone else experienced anything similar? 56 plate FR TDi.

I had a similar issue on an Audi that was left at the airport for a couple of days and was totally dead when I returned. It turned out to be the boot light operating due to a faulty switch. Prolly not the same issue (and I'm not too sure off-hand where the switch is located on my Leon), but might be worth checking?

Haven't had any problems yet on my 06 plate FR TDi but some of the Altea boys have had there radio coming on by it's self and draining the battery. Could be that...

Thought someone might be interested, took the car to the dealer this week and they found the gateway ECU was causing the battery drain.
Booked in next week for them to fit the new part.
Fingers crossed that will solve it!
