Moin, after viiieeeleen, almost unbelievable many OT contributions from me now again something on the topic of Volvo It is about the connection of additional instruments. Since a V70 unfortunately no turbo pressure indicator anymore has just as little as an oil temperature indicator (both is with the 850er T5 I believe with on board) I thought once, build you one. Then in the 3er-pack with oil pressure also. I thought, can not be harmed, if it is useful has put it there has cost the same as n 2er Pack! Now my question(s): Incidentally a slurry for the lade pressure (pane tree beside the engine block, search for a free port or use the T-piece) <---- charging pressure would be solved with it! The real problem is now that for the oil temperature n adapter for the oil release screw was included then with the question of the oil temperature.
