Here's the story, ... i tried to clean the MAF sensor yesterday for my 01 c240, while taking off MAf, i managed to break the yelowish elbow beside the MAF, that connects the black plastic hose that goes to a distributor and then the line goes thru the fire wall, i think it's the brake vacuum hose that goes to the booster, now there is no power brakes. The black plastic hose has the PN on it 203 429 27 29 [I think, but, the numbers 29 in the middle are faded, so, I'm not sure] has a U shape and is oriented upside down. The elbow seems to be very brittle... , ready to go to the dealer, and not sure how to take off the elbow. It has a sort of black plastic groomet right when it goes into the engine block. The groomet has 2 small wings that can be pushed inwards. At a certain point I was able to take the groomet off but this didn't do anything, so I put it back on. I just cannot take that half of the elbow out [did I mention that space to work on that is pretty much zero, not to mention tools]. The other half of the elbow is stuck into the U shaped black plastic hose... The portion of the elbow going into the engine block is just moving fore-and-aft about 1mm... it's very tight, dont want to break more stuffs haha... need help, thanks in advance, guys
