Volvo V70 – Reliability

Hello dear forum, at the moment I own a Volvo V50, built in 2008, 1.6 diesel, mileage at approx. 175,000 and use it for long distances with an annual mileage of approx. 40,000 kilometers. Unfortunately, the Volvo soon got through all popular errors in the ADAC breakdown statistics. Defects air conditioning, AGR valve and alternator, constantly the danger of an unloaded battery. The DSTC is constantly out on longer straight highways, especially in northern Germany. Since then, the vulnerability of this vehicle and the Volvo Assistance employees have been very familiar with almost all of them. Due to my driving performance, I need a reliable car. I don’t really want to separate myself from the brand and think about switching to a V70 soon after the V50. I have searched through the numerous contributions in the forum and still have an important detail to clarify. From which model year Volvo has no PSA-T Which model year or diesel engine has the highest mileage and as few abnormalities as possible? How do the vehicles behave qualitatively since Geely joins Volvo? Is there still the famous quality at Volvo or has this slowed down for years? Thank you for your expert contributions in advance.
