2007 E320 Bluetec fuel filter and brake flush
I am a first time poster who has done a bunch of searching before asking the forum...
I bought my wife our first MB last May. At the time it had 8,500 miles on it and it now has 20,000 miles and is exactly 2 years old. A couple weeks ago we had the local MB dealer do a C maintenance and they explained that the brakes need to be flushed and the fuel filter replaced every 2 years. The brake flush was to be roughly $110 and the fuel filter was going to be roughly $350. I chose to explore doing the work myself since it seemed expensive for routine maintenance. I had a 1987 Saab 900 Turbo that I worked on for roughly 20 years until I sold it a couple years back. My gutsiest repair was replacing the turbo. That was a knuckle buster, but successful.
I bought a Motive power bleeder and I'm looking forward to doing the brake flush next weekend. I swung by the MB parts counter today and spoke with a helpful parts manager. He asked one of the mechanics about the fuel filter and came back explaining that it takes the pros 3 hours to do the repair even as the book has it down for 2.6 hours. Apparently, there is a lot that needs to be disconnected and then reconnected beyond just the filter. They suggested it might not be a good repair for a shade tree mechanic to attempt.
I've pulled the engine cover and I can see the fuel filter plain as day. Unfortunately, it looks to be partially blocked by the ducting for the turbocharger and I'm guessing therein lies the problem.
Is anybody familiar with this situation? Did MB really locate a fuel filter that needs to be replaced every 2 years or 20,000 miles where it takes 3 hours to do so? Is this a project I could do myself with the help of the service manual DVDs? Or should I avoid doing so since my CPO extended warranty takes me through 2013? Might this be a good opportunity to go with an independent repair shop?
Thanks in advance for your advice.
