I had a direct TPMS on the first SPA platform car, a 2016 XC90 D5. Worked like a charm.
Then I had two cars (XC90 T8s) with this indirect system and it just did not work. I had all issues - false positives, tons of those, but also failure to detect 10 psi+ drops. It is pure garbage, and a totally puzzling choice for a brand that pretends to care about safety. Because trying to save $100 for sensors on car with $80k list price somehow makes sense to somebody?
Yet, we have beaten this horse to death. Volvo won't bulge, and I won't buy another one... but TPMS is, of course, only a minor contribution to that decision.
