08 SL65 IAT and Coolant temps
Replaced Bosch pump when installed new coil packs and plugs soon after purchasing car with 41k due to misfires. IATs running 140-180, so took back and flushed coolant system. IATs started running in 80-130 then went back up to 180s. Took to Mercedes dealer, they replaced coolant and bled system. Got back, runs good for 15 minutes then IATs go to 190s and coolant goes above 200. Dealer says this is normal and nothing more they can do. Using dashcommand on iPhone, dealer says not accurate and dosnt believe. Is their anything I am missing or is there something I can say to convince them this is not normal?

Maybe air not totally bled from system?

Took back to dealer, checked intercoolers and they have air in them along with out hoses. Schrader valves only released air. Apparently they did not bleed systems the correct way. Paid for it so it hope they do right second time around. Thought a dealer would know better.
