XC60 Overheating Error Memory Message
Summary of the thread
A 2016 Volvo XC60 diesel was experiencing an 'Error stored in the error memory' message and engine overheating. The initial suspicion was a bypass valve issue, but it was suggested that a faulty sensor could be causing the problem by sending incorrect data to the engine management system. After taking the car to a workshop, it was confirmed that a faulty sensor was indeed the cause, leading to the bypass valve malfunction and overheating. Fixing the sensor resolved the issues without needing to replace the bypass valve.

Hmm, power loss... maybe a little, but I thought I was imagining it. And now that you mention it, fuel efficiency seems to have taken a hit. But a faulty sensor causing the bypass valve issue? Is that even possible?

It’s not always a direct cause and effect, but on the Peugeot, the faulty sensor was sending incorrect data to the engine management system. This, in turn, caused the bypass valve to malfunction, as it was reacting to incorrect parameters. Given the overheating and error message, I'd recommend getting it checked at a workshop. Could be a consequential error as it was in my case.

Thanks for the advice. Took it to a shop, and you were spot on! It was indeed a faulty sensor throwing everything else off. They fixed the sensor, and that cleared the bypass valve issue and overheating, it didn't need replacing. Repair cost 0€!

Interesting. I had a similar issue with my old Peugeot 308. Same error message, and the engine was definitely running hotter than usual. In my case, it turned out to be a cascading failure from a faulty sensor messing with the air intake. Was the Volvo showing any other signs, like engine stalling or power loss?
