Hi, just registered on here as I'm having a problem with my E270 CDI that seems to be degrading quickly. It's 2003 and has 95k miles.
Last week on a 100mile motorway trip, I noticed that the turbo wasn't working correctly. It had been working earlier, but now acceleration is sluggish, it loses a few mph on the uphill, and max speed is just over 70mph. The Engine light came on, went out two days later, and hasn't been on since. Full power comes and goes, generally it's reset by restarting the car. I contacted MB dealer, but they've not looked at the car yet.
Now, a few days on, the turbo still seems to reset by restarting the car, but there is a very disturbing loud hissing noise coming from the underside under acceleration.
I stopped and took the car out of gear to have a closer look. There is air coming from the underside of the engine compartment when the car revs above c2000rpm.
Any ideas or suggestions appreciated. I have searched forums for the answers, but although the turbo problem seems common, the hissing has me worried.
