Hi every body,:D
(Excused my English)
Im new in MB world, I sold my BMW 320d, and I bought an S/H Mercedes Benz (80K Miles - 127K Km from 2007) a C220 CDI 170HP (W204) :p characteristics see Carfolio.
I bought the car with a little engine problem: when the engine is cold, in drive it runs uneven, symptoms like a cylinder has a misfire and the car shakes. When the car is warm (180 F aprox. 80 deg. C) it runs fine, it accelerates smooth and everything is OK.
I thought it is simple to fix it;), to clean the air intake, EGR, inlet manifold, check the swirl flaps and moving mechanism, max. an injector problem, like at my last BMW etc , etc
Yesterday, at a busy traffic light, the CDI engine quit in drive .:confused: and I create traffic problem .:shock: I must restart the engine .:Oops:
For me it seems to be more difficult to solve the problem at my MB:rolleyes:, and costly.
I visit an MB dealer to investigate and after a test computer, they told me to change the commonrail pressure transducer. All the injectors are OK. I think is not a big problem but the pressure transducer is sold together with all the commonrail tube (!) and it cost about £660! (800Euro) :evil:.
Ive cleaned all the electrical connectors I remove the EGR (electrically operated not vaccum like at BMW), I find the EGR in good condition, no soot build-up as I thought, (I think that also the inlet manifold must be is in good condition!).
I cleaned only the EGR perfectly. See pict.
After that, I test the car on the motorway, to clean all the exhaust, the turbine, the cataliser . After the motorway session, the engine run smooth and the MPG improves from 41 to 47 on motorway. I restarted the engine in the morning, when it is cold and it runs OK, but the second day the problems appear again.
I asked some advice: You hear about a problem like that?
