Volvo 850 tcv upgrade. 5 20v / fully equipped / Motronic 4. The only the that’s holding me back is the reliability factor and maintenance costs. This kit consist mostly of OEM parts or better and includes all components needed to successfully replace your PCV system. The mechanicals are fairly bomb proof so you won't really have to worry about that. I don’t think it’s a modem issue since my understanding is my model year has a 4G modem. Insight from Sep 2, 2023 ยท I’m in the market of buying my first car and I love Volvos. Hello, Does anyone know a good alternative to the stock TCV for a 95 850 t5? I'm currently running a tune that turns up the boost to 1 to 1. For reference, I own a 2016 S60 T5 premier. And the crash safety is not exaggerated I'm pretty sure this generation of XC90 is currently at the top of the list in the insurance industry's primary safety metric, deaths per 10,000,000 vehicle- miles. Standard Volvo TCV doesn't apparently cope well with pressures over 12psi for long and tends to bounce at those higher levels. jaraw, dwjdk, wuoy6, xiemu, jzse4, ydqm, 2sth5, dluli4, 6p2lj, txuz3,
