- C220CDI/2007/OM611 170HP
Hi every body,
(Excused my English)
I’m 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) – 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…. and I create traffic problem…. I must restart the engine….:Oops:
For me it seems to be more difficult to solve the problem at my MB, 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:.
I’ve 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?
