Started looking for the cause of the drain on the battery. I found that I was getting a 216mA drain. So I started pulling fuses and relays to see where it might be. Then I pulled the relay on the ECU, to my surprise it was hot! The draw dropped down to around 60mA. I swapped it out with a different relay, and the draw was back up to 216mA.
While I'm going through the ROM and CD trying to figure where this might come from, any ideas?
And, 60mA still seems high, is it?

Well, at least I can positively say that there are no frogs anywhere to be found!

Looks I spoke too soon. The relay is not on the ECU, but just under it. I couldn't figure out how to delete this post and start again!

 

Yep still a bit high, have a look at the chart below.

Hope it helps,

 

Looks like what it really is, is the relay to the antenna mast motor.
Yeah, I feel stupid.
Thanks jimbov8, that does help. I've got a few aftermarket things on the car, but I'll keep on investigating.

 

Keep us updated Bill, always willing to help if I can.

 

If I left my car for 2 or 3 weeks in the garage, the battery would not start the car. Several years ago I connected a battery conditioner/trickle charger to the car & I haven't had a problem since.

This thread inspired me to connect my multimeter between the negative battery terminal & the ground cable & guess what: I've confirmed that I have a problem I kind of suspected I had but had been able to ignore. The battery drain was jumping between a low of 90mA & a high of 120mA - between double & treble the levels quoted on the chart.

Now I will have to look for it & I will 1st try the electric aerial relay - I seem to remember these are a known culprit. I wouldn't be surprised if it related to the electric seats though as the car had issues there caused by water ingress prior to my ownership over 8 years ago.

Wish me luck!

Andy.
