Hi All,
I addition to intermittent gear selector problem whereby the gear is not going from Neutral to Reverse unless brake pedal is released (W211 E320CDI 2007 facelift intermittently gets stuck in Drive gear), which now happens very rarely, my car developed another intermittent problem.
About 25% of the time when I start my car from cold the car is underpowered due to a loss of turbo (or so I think). If such loss of power occurs, using manual gear selection enables me to get the car up to any reasonable speed (70mph no problem) - obviously, not as quickly as with turbo, though. When this problem occurs just switching the ignition off and on, even very briefly such as at red traffic lights, more often than not cures the problem. Sometimes the problem occurs even when the car is started warm. Dashboard check engine light appears and disappears (when driven several times without the problem it disappears, then when problems occur several times in succession it reappears).
There is never any juddering. I noticed even when I have this turbo problem it generally appears after about 10 seconds of driving and I have been trying to capture that moment of turbo loss by trying to accelerate heavily for the first ten seconds from start - but was never able to capture the moment.
I had started using Shell Premium Diesel with the view of clearing the systems of various deposits just before this problem started. Switching to Costco Premium Diesel seemed to coincide with reduction in frequency of this problem. Perhaps this is a coincidence, perhaps not.
In the past I had an actuator fault on another E320CDI facelift but there was a lot of juddering shortly after starting a car and turbo-power would be lost only after severe juddering.- and there is no any juddering at all with the present car.
Any thoughts on what could be the problem are welcome! Thanks a lot in advance or any repplies!
