Well as its my old car - I have tried all the fixes, bought new battery, new alternator all to no avail esp. if you dare to use the FBH.
My pragmatic approach was to connect the C-Tek via the White tow bar socket overnight so I could leave the car locked, use the FBH in the morning and just having to remember to disconnect before driving off, I found you could actually disconnect before starting which makes things even simpler.
By all means try the fixes, look for current drain, change the FSR etc etc but the C-Tek on all night never once let me down even on the coldest mornings, lights, heated seats, heated steering wheel, FBH all on every day short run to what passed for work (in Bolton actually) never a problem, never late or rushed  Geoff

I'm going to see about getting an external power socket on for that to make it easier. I also need to get the tow socket replace as it melted when I connected it to my caravan - now I think about it I wonder if that has caused a short???

Does it have the towing sockets fitted? If so they are the easiest solution and can be setup in such a way that you can drive off and he connection just pops off  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Yes, it does have sockets I just need to replace the grey one but I may change to 13 pin at the same time. Car has started fine again this morning

Making up a towing adapter then is a doddle only took me about 5mins in total  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Mmmm, yes, a towing adapter. I think I will make one of those, was thinking of just a sort of laptop type doc plug and socket (Maplins etc) , for a dc supply plugged indoors, a length of external 1mm flex, with a mini fuse inline, and some sort of rubber ball or shroud, , so that when I drive off, the plug will fall and be off the ground, so rain will not adversely affect it. What is the connector I need the tap into please. I have a 13 pin, with a 7 pin adaptor plugged in.
Came out today, and mine was flat, been standing for only a couple of days. I took off my 7 pin towing adaptor and its green with verdigree. Perhaps a resistive bridge for 12v to leak across. I will change it out, if I can't clean it up. Perhaps a hidden problem for many of us with the battery issue..
As questioned, what is the perm live colour to tap into.

Happy new year!

The ones you need to tap into iirc are the always on + and ground connections or sometimes called direct battery feed.

There is a post on the disco forum I think that lists what it is for the 7pin, so not sure what the 13pin would be.

Then I have a ctek connection at the end hanging off it with the spring clip part removed so if I drive away accidentally it just pops off

Not done that yet but thought id do it just incase the other end is stringed onto the garage door so there is s little give in it  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

So far so good, no problems starting over the lase couple of days.

I have noticed that the passenger mirror no longer dips when reverse is selected - is this a setting that can be changed with the iid tool? Could this have reset due to the battery issue? The mirror still adjusts normally with the buttons so I know it works.

Move the slider from the passenger to The drivers mirror on the mirror buttons panel on the drivers door and it will go back to working  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Wow, that was easy. I don't even remember moving.

Thanks

Well, the car has been fine so far.......


.....until this morning! It's was freezing overnight with a light covering of hail / snow so I put the FBH on for a few minutes and lo and behold - it won't start.

Charges back on and I'll get to the garage later for a proper test.

Same here Fish but my flat battery was in the XM I wanted to use this morning. When it was slow cranking i just went back inside and pushed the ON button for the ff and had a drink and sorted some bits out before going out to a warmed and defrosted car 10mins later 😄😄 FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Battery has been tested and showing good and the alternator is putting a charge in. Im going to check it each morning before I start to see what voltage is in it and if it is dropping then go from there.

I checked the battery this morning before I started up and it was reading 11.9v. I did the short trip to work, 3 miles, and check it again and it was 12.2v. I'm going to keep an eye on it but also get one of those battery monitor gadgets that plug in to the 12v socket to see of anything is happening. This morning I read through the very long thread of ibartsimpson who had a very bad battery issue and there was a lot of useful tips and advice in that.

As you have had trouble with the towbar electrics I'd be inclined to un-plug the the towbar electrics and see what happens over a few days. I would be concerned the socket melting may well have caused a partial / intermittent short to earth sufficient to cause a current drain.
