Volvo V70 intermittent loss of power/speedo not working
Our 2000 v70 auto estate with 185k on the clock has never missed a beat. Today the exhaust started to blow at the beginning of a 40 mile journey. car was normal besides the slightly noisy exhaust when we stopped. When we started the return journey, the car felt like it was in winter mode with slow acceleration and gear shifts, there was a clunk ( like going over a pothole minus the pothole) and the speedo needle dropped to zero. A few times it came back up and then clicked and went off again. After 20 miles I was approaching traffic lights and had a loss of power, car was running but no acceleration at all and I limped it through the lights, speedo came back on and it picked up momentarily and then started running really rough like a cylinder wasn’t firing properly. Stopped the car and debated whether to phone breakdown. Started it up again and it was fine , just the exhaust a blowing , and drove it the last 20 miles with no issues at al, and speedo stayed working. I’m wondering if anyone had any ideas or if the exhaust could have affected a sensor ? I really thought the car was knackered when it was running so rough but the fact that it went back to normal after wards is confusing. It started up no problem every time I stopped and restarted it. Any thoughts appreciated. Don’t want to get the exhaust replaced if the engine/gearbox is going to pack up!
