So what’s the status of this issue. 

M326: what about the vcharger lamp, above the SAX1 connector on the stand? is the light very low?

if yes: charger problem.

you can try to reset the charger by:

switch off the system, disconnect the mains plug, disconnect the battery "-"pole, sometimes after 10s the chargerlamp will flash once. Wait 5 minutes, reconnect the battery, switch on the system. In many cases the system will work normal again. if not: exchange the ESU.

good luck!

M326:

    Henk, Thanks. Followed your instruction twice. Same M326 error message repeated. My vcharger lamp is completely off. When connect with SAX1 connector, it only blink once. Replaced the battery in early 2015. This not a battery issue.

check wiring to connection area SAx1. 

 Just because you changed batteries 3 plus uears ago does not mean they are still good. Dont assume.

when you changed the batteries did you change the charger baord also? Reason I ask is that when you have tanked batteries you are working the cra_p out of the charger.

M Chang..are you in bellevue??

are you still struggling with this problem? 326 can be a charger problem.

Do you have a logfile? You need BVScope + IST-key for downloading the logfile from the system.
