V60 PHEV D6, Hybrid System Malfunction

[JeffCooper63]

Yetsreday, just before setting out for my wifes first vaccine shot (!) I got the infamous Hybrid System Malfunction error message. Car worked fine in all modes, and message was erased with the reset button. 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 had this last weekend. The car had a battery showing 21 miles left in it yet wouldn’t run in pure and in hybrid setting used the engine all the time. And, bizarrely, the mileage fell to 18miles over a 15 mile journey even though not being used. Not yet had chance to speak to dealer but i can say i wish i had never bought this car.

Ah, thats a bit different - it's a known quirk of the car - in theory, you just stop, turn everything off and wait for a couple of minutes, after which it should behave normally. That's just a weird thing once in a while, and not to be concerned about luckily for you.

Thanks, i had the aircon compressor replaced at purchase (after the dealer told me it had been and yet clearly had not) and a replacement 12v battery to address other glitches. On more than one occasion it wouldnt do anything, no power in any settings. I love the concept, just not the execution of it.

It's strange - I don't know what year yours is (?) but apart from a couple of occasions with the same stuck in engine mode glitches, and with this error message maybe appearing a couple of times, I've found the car to be brilliant - so much so that I've spent money upgrading it - front wide angle and rear cameras, front parking sensors, RTTI, swapping out the windows for factory tints etc - planning to do long distance european road trips in theory - of course the world decided to stop us doing that !!!

2016 however it is R Design spec with additional options specced by the previous owner so apart from a front camera wants for very little. It is a fabulous mile muncher, drove to Prague last summer and it sits rock steady at 100mph on the de restricted autobahns and still giving over 40mpg. Putting aside reliability and unimpressive dealers the car is comfortable, great seats, good sound system, tows our caravan very well (better than previous Passat Alltrack) but numb steering inhibits driving on the twisty bits and the brakes, while powerful, lack any feel.

AC compressor in D6 is prone to fail.

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

Ok, thanks for the above - I tried it and ran into a slight problem, which hopefully you may be able to throw some more light onto.

Basically, I have a viecar connector, as shown on the carscanner adapters page, and it will talk using the EOBD/OBD connection profile, but won't connect to the car ECU using the V60 PHEV profile - I'm assuming it's a protocl problem, but am hoping that might trigger a memory of something !!

cheers

Well after a lot of searching/reading on that dutch forum, I discovered one sentence someone had posted that coincided exactly with my issue - namely that the level 1 isolation fault can be issued whilst pre-conditioning with the car plugged in after a full charge. I think this is the second time I've seen the message, and I'm pretty certain that the first time was straight after a pre-condition as well. SO I'm sort of less worried.
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 ?

The AC compressor failure is common. Mine had it on purchase last year and eventually got the lying Volvo dealer (claimed it had been repaired when a blind man on a galloping horse could see and feel it hadn’t) to change it at their cost.
