Quote from: Jan S on 24 October 2021, 01:19 PMYesterday I replaced all 8 injectors inclusive the rubber seatings.They had to go - old and rubber seatings were stone hard.I tested them with a borrowed tester - both new and old. Spray patterns were fairly ok, but half of them leaked and had a tendency to squirt instead of a "fine shower". New injectors were fine.Unfortunately the tester had a diesel gauge 0-3000 psi - impossible to check release pressure in the range 3.5-4.5 bar. Good enough for now.Car started immediately. But rough idle cold is still there. Cleaning cooling system and replacing thermostat this week. Then the newly inspected, tested and cleaned AVV will work as it's supposed to.
Quote from: UTn_boy on 09 January 2022, 12:42 PMDid you install an aftermarket thermostat or a genuine Mercedes thermostat? Aftermarket thermostats are often bad out of the box. Also, have you confirmed the engine temperature with an infrared thermometer to make sure your gauge and/or temperature sending unit isn't reading incorrectly?
Quote from: daantjie on 09 January 2022, 12:43 PMMaybe you have some air bubbles stuck in the coolant path however in my experience this usually leads to rapidly rising temp on gauge. Let it cool down then "burp" the coolant tank by opening the cap. Also you can run the heater when you start it again to make sure the coolant is circulating through the heater core. Might have to burp it a few times to get all the air out.
