After finding the charging problem last week, my battery is still draining slowly, it's been used for 3 shorts runs over the last 6 days since i fixed it. Yesterday i went to start it and it felt lazy, today it almost never started. I have disconnected the earth lead from the battery and checked for earth leakage between the negative lead and terminal and it's drawing .3 mili amps so thats ok, I've checked it 4 times over 2 days. The battery is around 18 months old from memory. could there be something else or is it purely the cold killing the battery and minimal use? I'm going to disconnect it and give it a full charge with an optimate 4, what baffles me is that 6 weeks ago i took it out for a 70 miles round trip and the next day it got sluggish to start.

So an update, luckily it ended up being a loose plug on the alternator preventing the alternator kicking in until the engine reached 1500rpm. I don't know how this has came loose or if someone in a garage might have done it in the past.

I will update here once I get some spare time soon. Hopefully the next week

Thanks very much, I will get a look at this next week hopefully. I have checked again at the battery and when started with everything off it only puts out 11.8V, then once it's revved over 1500rpm once the alternator kicks in properly at 14.5V and remains at this.

Hi, It's a 2010, Whereabouts do i find the engine code, If i'm looking at the correct part the code is CFG, is that correct?

Skoda superb elegance 2.0 TDi DSG My battery went flat around 12 months ago, it was old so I got a new one, before i did i checked what the alternator was producing and it was very low, but once revved over 1500rpm it kicked into full charge. If i remember correctly, it only had to go above 1500 once and the alternator kicked in and continued to even when idling at 900. I told a garage about this in an MOT and they still left lights on and flattened my new battery. I managed to get a new one under warranty but it's gone flat with the cold and not using it often enough. I was in it 7 days ago for a long run out but it's dead now and on charge with an optimate. I once seen on here about a gearbox overrun cable that can cause this but no more info?
