Hello together, first of all, I have little idea of cars, so please for tolerance. I drive a Volvo V60 Diesel, 163hp, BJ 2015, 130Tsd KM. So far I had no problems. I use the car only to commute to work (one-way 45km). A short time ago a message appeared on the display on the way to work: “Maintenance engine system required (or similar)”. At the same time the power of the engine was severely throttled. Until then, the problem had disappeared on its own and also the message. The error memory resulted in: “Regeneration time particle filter exceeded (or similar)”. The car mechanic could not do much with it, advised me to turn directly to Volvo when reappearing. At Volvo I had also called afterwards and they could not do anything with the problem description. Today the problem has occurred again. It was remarkable that in the days before the first appearance of the problem I drove more short distance than usual. Do you have any advice? Thank you.
