 Booking into garage for someone who is a little more savvy with electrics to pin point the draw. 

A wise decision, which two of us have previously recommended, and all the more worthwhile in view of your latest revelation of a damaged plug.

The Bluetooth thing was a no go, I'm going to disconnect alternator and id its still there I'll book it in. Thanks for all the advice. The plug crack would of been fine it was still secure just missing a bit. Bought a new one for 6 quid and spliced it in. Still drawing 1.4 amps with radio fuse out so its not that. Garage it is!

So booked it into garage and they did some chasing, couldn't pin it down but said it may be a module behind the dash? I then went to see a guy who has owned a few and he said he would have a look for a grand up front! Please see screen shot from diagnosis carried out by the garage. Central locking? I've had all relays fuses out including the ones under the bonnet. Starter relays the lot! Central locking or imobilizer? Bose amp? Something didn't like being unplugged for 2 months!

The report mentions the 1.4 amp drain appears only temporarily then drops to 50 milliamps, which is exactly what one would expect from a sleeping car with remote locking. If that current is enough to drain the battery overnight it points once again to the battery being at fault. You told us it had been renewed, but did you code it to the car as I suggested on 23rd July.

No I have not had the battery coded yet until the car has decided not to drain it. Fuse 38 out drops it down alot? I will do a bit more investigation tonight. 12.8v in battery and when running ticking at 14v with slight drop and climb as expected with a healthy alternator. 

Lack of coding means the battery may not be charging correctly, thus leading to battery damage and the sort of problem you are experiencing. I suggest once again you get it coded and hope the battery has not been ruined.

I will try and get this done next, thank you for the advice. 

Been a while! So to wrap up this thresd it was the rectifier pack on the alternator that was causing the drain. Alternator changed and all codes deleted that arrose from diagnosis now she has been fine for a few months. It did destroy the battery tho which was a pain. Thank you for all the advice! Nice to ger it out the garage every now and again for a run! Next job im thinking is seeing how the carbon build up is. Doesnt seem to effect the running as it ticks over like silk.

Thanks, but didn’t I say so a long time ago!! ?
