Just curious , managed to track down my issues , its corrosion where the live cables, splice around the rear fuse box, check the 2 relays, one will probably not have a live feed to it.

Solved , its corrosion , where the live cable from battery is spliced , Nothing at all to do with the battery , mr staff member know it all. Could have cost me £200 quid for a new battery.

Hi op, whats the issues you are having, because my car is dead ? had lots of faults issues , then it died, see my post on A5 FORUM. Was guided along the lines of BMC2 MODULE could be faulty , sent it off to Pelican diagnostics, who has returned it ,saying cant see any issues with it.

Spare battery no charger attached is a 95ah 800a multi meter reads 13.82v Battery on car no charger is a 95ah 750a multi meter reads 13.21v How can you convince me battery clapped out. I said numerous times , not a battery issue

well it seems a staff member has no idea but has plenty of sarcasm

Both batteries are reading over 14 volts

And i did put another battery into it , nothing changed

At a loss now, sent off the bmc2 for repair, said nothing wrong with it,

The battery, regardless of how big or small it is at the moment , is not going to wake up failed modules. I am now charging up battery that is suitable , just to prove this point. Like i have mentioned the smaller battery never gave me any issues, up until this point. Have spoken to a Audi independent specialist, who said Audi modules are very sensitive to power supplied. By spikes and low currents,anything as low as 9v can ruin a module , he did say the best course of action is to disconnect the battery, when car is going to be laid up for some time.

https://webautocats.com/en-gb/etka/audi/a5co/620/907000/ Both are connected. How to determine ,if both are broken oe a single one ?

Yes ,it holds a charge

Hi ,unfortunately ,unable to connect to car for fault codes,,which is why i've come here Also the battery does charge back up

Hi , its slightly smaller than it should be, about a year old, never had any issues with the battery , until it got taken off the road, with the cold weather and it not being used, this is the fifth time its been charged.

Hi all, wondering if anyone can answer a few questions. Audi is dead. What led to this, car been off road for a few months, fan belt snapped on motorway, fixed, was then having lots of fault codes, that pointed to a fuse in the engine bay, replaced the fuse, the throttle body connector caught fire.Had a water pipe burst that i fixed, so unsure throttle body got wet. replaced throttle body, Dpf blocked at same time, went into limp mode. So off road for 2/3 months.Managed to clear out DPF, car back on the road, yippee. Then handbrake faults, cleared codes with OBD11. codes returned , good old google and other forums etc, suggested changing handbrake module, For battery issues , going flat , not providing module with the power needed. Handbrake module is plug and play ?? swapped handbrake module, ok for a day , same faults but when handbrake used ,stalled engine . clear faults , then noticed smoke from area where module is located.Put original module back on , then got a hell of a lot of issues , component protection activated U fault codes, no dash lights , no start, would take car ages to wake up, to start, then would not turn off when key pushed in. lots of clicking sounds in the rear, that i think were coming from the comfort control module. Now the car is dead, had battery on charge , thinking battery related, nothing works, apart from windows , hazards, seat motors. So questions , seems to be the comfort control module is dead, is there another module that controls the comfort one, Obd11 faults before car died, mentioned control module A or is module A the one in the rear? How did i get all these faults, by swapping handbrake module, same part number , but different letter at the end.( Firmware upgrade ) Would cloning or have the comfort module repaired fix this car ?? or is there another module, that needs repairing alongside??
