Hi Everyone,
I'm have to notice that my W211 E280 2006 Facelift engine will vibrate or twitch during the first 30 seconds or so after cold start. However, after about 1 minutes the vibration is totally gone. Anyone have this experience and may the root cause be?

Best Regards

 

What were the last 60k.Mi maintenance items ??

What are the reported chassis fault codes ?

Refrain from replacing any lucky-parts unless confirmed bad. Don't use questionable suppliers...

 

Mileage: 277000KM
I got no fault code and I also check fault on each Cylinders: None
Last maintenance item was ECU replacement due to the original one died. Data was cloned to the donor used ECU
Have changed all spark plug and one of the ignition coil as well

 

That's a likely good ignition.

Use your scanner to read :
-- the long term fuel trims?
-- the fuel rail pressure?
