MY2021 XC90 - Critical charging fault

[gaz132]

I've had my new B5 (mild hybrid) XC90 for 2 weeks and 167miles when it threw up this error message and went into limp mode (~5mph max). After about 30mins it cleared itself & I could drive home. VOC had turned up & I was waiting to be recovered when I tried it again. Anyone else had this issue? Dealer says it's a 'known fault and Volvo are looking into, but don't have a fix'.

Happened again on Sunday. This time I left the car locked for 10/15mins, went back & the fault had cleared. Going into Volvo on Thursday, but I'm not holding my breath.

The car went to the MD, where they just did a diagnostic download of the errors created when the fault happened. These went to Volvo Sweden where the techie bods removed their rimless glasses and pinched the bridge of their nose. While they did this the car came back to me. Yesterday it went back to the MD where after further discussion with Volvo Sweden it has been decided to replace a battery sensor. Unfortunately this sensor isn't in stock in the UK so the car will go back to the MD the end of next week to be fitted. Hopefully this will resolve the issue. The fault hasn't happened again since Easter Sunday though.
To be fair the MD have been pretty good, so far. They gave me option of their curtesy car for the week so lets hope this resolves the issue.

Theres now a fix for this issue, fitment of a bus bar and nut onto the secondary battery

Yes thanks Daz, this along with a software update was completed by the MD on Thursday so fingers-crossed it's now fixed.

Yes fixed at the dealer and no reoccurrence of the issue.
