Hi,

Have a problem with a 2016 XC90 and have been told the following from a workshop. They say they don't know exactly what the problem could be and may cost thousands in trial and error.

 

Did the shop clear (I'm guessing there were) the codes?

What codes have come back?

 

That is the codes that came back.

BTW is there like a china type diag cable for volvos?

 

Those are descriptions of codes, what are the actual codes?

Cat efficiency code is usually something like a po420 - and could mean the cat converter has a problem - or could be related to the -----------

Turbo/supercharger under boost - I've read there is a "gasket" on the supercharger that leaks - and creates a code.

Cam position - sorry got no ideas on that one.

(but 2 codes might be solved by fixing an air leak on a known failure with a gasket near the Supercharger)

And why was the AC low on freon? Was a leak discovered?

What do you mean by a "China cable"?

 

ok thanks for the info. I will try to get the actual codes.

I mean like VIDA / DICE it seems to go to 2015 only

 

That is true. If you want to use VIDA on a 2016+ , A Vida subscription is required and the interface is a relatively inexpensive Ethernet cable.

I'm sure there are plenty of aftermarket scan tools of various prices/capabilities that can talk to 16+ Volvos.

 

How do you go about getting that? I would like to be able to do diagnostics myself.
