2006 Cdi Vs 2007 Bluetec

If mercedes truly felt interruptions were an issue, they would have put some sort of indicator in the cockpit so you were aware it was occurring and would continue driving until complete. This may be the case on the VWs, but not on the bluetecs. You might have said: The DPF is part of the exhaust system for the 2007 and later MBZs but not in the engine compartment, and you would have been correct for not only Mercedes Benzs but probably most vehicles that have DPFs. The DPF is located under the vehicle and is inline. But not for the 2009 and later VWs and Audis, at least the A3. Don't know about their SUVs. With all 2009 and later VW CR TDI Jettas, Golfs and Audi A3s, the DPF is in the engine compartment under the hood, and as you say, when interruptions occur, the burn continues until it is done or finished and the fans will remain on until the temperatures drop to a safe level to help keep everything else under the hood from getting cooked. As you may know, that DPF is really hot when regeneration is occuring! See: http://www.myturbodiesel.com/1000q/D...AQ-VW-Audi.htm You can see which part is the DPF. It's the vertical part that is within the engine compartment, under the hood and it is located right up against the back side of the engine between the motor and the firewall. It's very hard to get to, and I hear it is expensive to replace not only for the part but because of all the labor involved with having to R & R it. One of several reasons I sold my 2010 JSW TDI and bought a CDI with no DPF. IMHO, it is better to buy a good used CDI with the same money than to buy any new VW TDI. A much better vehicle for the same dinero. Derrel

Perhaps I should have clarified that I was referring to mercedes bluetecs, as this is a mercedes forum. I have no idea how VW implements their system, but it's likely cheap, inferior and prone to breaking like everything VW produces.

But you would know IF you read this:

Cheap . . not if you price the spare parts when they are or will be needed
Inferior . . not really as it does work and work well for now
Prone to breaking . . no, as we haven't heard of anyone having one fail . . yet!

Now if you want to talk about their HPFP (High Pressure Fuel Pump) failing and costing $10K when VW does not cover everything,
that's an entirely different story.

Arguably one of the worst constructed sentences I have ever seen on a forum, let alone our peanut gallery known as MBW. Seriously. Tis wasn't meant as a joke. Even for an ESL, this is awful. Please stop posting for fear of offending my delicate sensibilities. Enough forum members here have had my sensibilities all too delicately
