SL electrics gone haywire!

[Sandy - SL]

Hi, having major issues with SL 350 2004.
Began with the convenience functions unavailable, clock losing time. central locking doesn’t work. Heating/air con no longer working. Petrol cap wouldn’t open or boot lid! Can’t open roof! Now dash has constant red battery warning to visit workshop!
Both batteries have been replaced.
indi has suggested removal and repair of SAM - car will be off road for around a week.
Does this sound correct or something else? Thanks

In the boot under the carpet is where I’d start

Ok, thanks, I’ll take a look.

Ok, thanks, I’ll take a look.

Just make sure you can open the boot with the metal key.

Check the airbox under the bonnet on passenger side doesn't have water pooling in it. Check under the passenger side carpet because if the airbox has leaked it will go into the passenger footwear.

No sign of water in the boot!

Check the drains under the front scuttle. They tend to block with accumulated dirt and water finds its way into the front driver and passenger foot wells and ruins the front SAM.

Such a shame the SL model leaks like a sieve in so many places. It really is their achilles heel.

Have you lifted out the carpet and felt under the PSE pump?

What is you battery voltage like? Should be 12.6+ volts for tip top condition.
How old is the battery?

Battery has been changed but it is draining somehow!

Sounds like water under passenger carpet. There is thick foam underlay which holds the water beautifully. Copper connectors go green and stop connecting.

Very difficult to get under carpets, you need to remove door sill trim and slide your hand in. It will be wet, I suspect.
