Moinsen, my 850 T5 is starting to make me feel at ease when it’s cold and I start it, then it starts clean and goes straight back out. After that it gets really weird, because it spins like it has NULL compression until after a while the first “Poff Poff Poff” come out of the exhaust. Then it starts on 2, 3 or on good days 4 cylinders and shakes like stupid. If I wait a moment the 5th cylinder comes in. Gas is the first 5 minutes It’s not in it, it goes out dull. The curious thing is, as soon as it’s warm it runs perfectly. The idle is nailed like, it takes gas and drives in order. There are no clouds coming out of the exhaust, neither blue, black nor white. I am now something at the end of my Latin, since I have already tried a lot: – control times are set to 100% with gauges – petrol pump is replaced – petrol filter is new (MAN) – petrol pump relay is replaced – intake manifold seal is new (OE Volvo) – ignition finger and cap new (Bosch) – ignition coil and cable from mid-2014 (Bosch and OE Volvo) – Lambda probe from mid-2014 (Bosch) – LMM from mid-2014 (Bosch) – EVAP check valve from mid-2014 (OE Volvo) – oil trap including all hoses new (OE Volvo) – candles are new (OE Volvo Turbo) – LiMa from mid-2014 (OE Volvo) – petrol pressure regulator new (Bosch) All vacuum hoses replaced by Samco, only in case that is required The compression is on all cylinders in the was I have already removed the coolant temperature sensor in the hope that the wrong values will be delivered and the MSG will then get an average value, but no change has been made except for the expected continuous running of the fan. MSG has not filed any errors. So if one of you has a well-founded idea, a reasonable suspicion or the possibility to read live data in the Hamburg area and direct I’m very grateful to interpret ig for further suggestions or assistance!!! But boys and girls, don’t be wildly rumbled Many greetings Johnny
