V60 PHEV D6, Hybrid System Malfunction

Having said that, I also read that for cars that haven't had their AC pump changed under the original warranty, Volvo aren't changing the pump under a 100% goodwill system, so I'm left, having found out that both my ISG and AC haven't been changed according to the Volvo IT systems, worrying about them failing.
So I'd really like to get a feel for how likely those items are to fail - does anyone have any data on this ?

Volvo were doing "goodwill" on cars up to 5 years old, my compressor went just after that but the dealer managed to get a 33% goodwill contribution. Someone on here has found a company that will repair them, there was a thread about it a month or so ago, so that may be a better/cheaper option.

@jeffcooper63 - I haven't made enough posts on here to reply to your PM directly. However I have found the thread I remembered:

https://www.volvoforums.org.uk/showthread.php?t=307542

Only issue is (which I hadn't noted at the time) he seems to be based in Romania, if it is just part of the motor that needs rewinding then there should be firms in the UK that can do it, alternatively importing one from Romania may not be too bad (and almost certainly cheaper than a new one from Volvo).

Find an elm327 adapter and use Car Scanner ELM Obd2 app

select Volvo V60 D6 profile, then compare:
AC compressor requested vs. actual status, requested vs. actual speed, requested vs actual power consumption

Can you give a bit more specific info on how these factors could diagnose the potential AC or ISG problems please.

Don't know much about ISG.

As for AC compressor it's just an educated guess, but I presume that expected/actual values are identical (or almost identical) while you diagnose a car part. Any discrepancies might be early symptoms of failure, even before an error code is stored.

Putting aside for a minute the horror stories of AC compressors failing and being/not being replaced under warranty.

The actual root cause of the pump failing was found by Volvo to be the fluid and gas the system was originally filled with.

The important question you need answered is not 'has the pump been replaced', but 'has the Volvo preventative maintenance which involves completely draining and fully flushing the AC system before refilling with the 'new fluids and gas''

This should have been performed by the supplying dealer at no cost to the owner.

Hope that helps ?

Ok, quick question - I have already had the error message come up (the isolation 1 level version) so would we say that it's already too late to have the aircon flushed and refilled using the new spec to try to stop it getting any worse ?

When we got home, I connected up my icarsoft i906 code reader, and got the stored code C105700, which is a Level 1 Isolation fault apparently - again this DTC was erased without any problems.

Googling this implies it could be something to do with the ISG or the A/C pump, so I rang Volvo, and a dealer, but neither would say wether the "we'll replace it if we need to free" atitude that has been seen in the past is still valid.

So what I'd like to know is wether anyone else has seen this code appear, possibly multiple times, but found that it actually never made any jot of difference to the car itself !!

I just drove my 2017 V60 twin Engine D5 home from work today in the same state. It had stopped charging at 94% full from a 3.3 kW fast charge pole and all drive modes worked, pure electric range was about what you'd expect from 90-95% full. Got nearly as far as on my normal run home at 100% before it switched from Pure to Hybrid. Regenerative brake / downhill stretches and the battery charge indicator show it's recharging while driving.

Once home, my "smart" charge cable triggers blinking red LED on the car's charge socket and a hybrid system, service required error appears on the dash.

How did you reset yours?
