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.

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

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.

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 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!

While the car is trying to sleep it sits at about 4 amps then after a few minutes drops and settles at 1.4 amps. I'm going to remove radio fuse and see if it goes away and if it does, rip out the Bluetooth and get an aftermarket headunit

Just talked to a guy who said it could be the Bluetooth until trying to find my phone? Could be the 1.4amp draw?

The only time I have had it to 0.05 amps is when both alternator and starter leads disconnected. I'm just wondering if the starter was drawing the power. So last night I left it with all connected and it was drawing 1.4 amps. Then jacked the car up and disconnected then 3 starter leads and left it. Still drawing 1.4 amps. Tonight I'm going to just remove the alternator plugs and see if it still draws 1.4 amps at rest. If it does i can't be those items. It must be something else. If it drops to 0.05 when alternator plugs removed I'm assuming its the alternator which was fine before any did any poly belts and starter work. I'm just thinking its something ice touched hence my reluctance to think it was the battery or alternator. The only other thing I can think is maybe the engine mount? Could it be inducing a fault seen as that plug has been off? Could remove that fuse to see if the drawing goes?

Last post on this as its boring now. New battery fitted. Starter disconnected, drawing 1.4 amps locked out sleeping. Disconnect starter. Still draws the same. Connect it all back up with a new plug as its casing was smashed and glued together. Wire still connects fine just cosmetic. Still drawing 1.4 amps. Booking into garage for someone who is a little more savvy with electrics to pin point the draw. Thanks for all the advice but I'm not taking it to bits for a 3rd time. Need some direction before stripping again

Just tested all relays and are fine. Car is sat now locked with new battery let's see if the draw drops off once its fully asleep?

Which one is the starter relay? All videos or links ive used all have different ones! Thanks in advance

Just bought a new one and going to install it tonight. Leave it and see if it drains again! If it does its going in to a garage that specialise in finding Eletrical faults. Then I'll follow their advice. Wish I still had my VAG reader.

so i thought it had been sorted. after i took the advice i locked the boot manually and lock it up , leave 20 mins and no draw 0.05 at most, starter back on , everything back on wire wise. left for 48 hours and flat again. Before i play it safe and put on a new starter and battery i need to know whats draining it! when battery is charged if i lock car and leave as normal but remove the starter relay then i know its the starter? I cant change the battery / starter and alternator just on an hunch, when they were all working fine before the strip. all that came off the alternator was the earth and small plug, the same for starter earth, main plug and small plug. car starts fine it just doesn't fully sleep when locked up. tomorrow charged battery back on with starter relay removed, if it holds charge, change starter relay. if still draining im stuck.

starter motor out all leads disconnected from alternator, still drawing 1 amp when doors closed and just boot open to get to battery. radio fuse removed, I'm thinking it must be the immobiliser? at least i can reinstall starter and reattach alternator leads. something is stealing my amps when at rest

I will disconnect the alternator and see if the draw drops off, If it does then it might be the alternator leads. Yes if it does in fact begin being a pain i will get it booked in somewhere and bite the bullet. Also i have nothing after market on the car that has been installed since it was working fine.
