I noticed that my car (508 2.0 163hp 2011 323000km) has developed some issue.
Issue is that when i first start my car in the morning, it turns on well, but engine noise is loud and i can feel and hear interior plastic moving (cant find proper term for this). Also RPMs are high on startup, and they stay around 900 RPMs for couple minutes and engine is sounding rough, also while driving and when car changes gears(6-speed automatic) it feels like juddering but only for couple of minutes, after that car is running perfect.
I have 3 codes: P0473 which i will be resolving soon, just need to replace Exhaust pressure sensor
P1621:control unit Characterisation: Software redudancy fault at the injection(level 2)status: intermittent, this showed after i did small service to the car(replacing filters), but the problem is present and before doing that.
P1498:Air metering valve Characterisation: intermittent, this fault is fixed(replaced air doser),just need to erase it with diagbox,which my diagbox cant do.
Any suggestion what is causing this would be appreciated, and thanks in advance.
