OM642 - Options for DPF & EGR Delete?

[bigchingan]

I've had an 07 OM642 (non SCR/DEF/UREA) powered E320 Bluetec for the last 7 years and love the hell out of the thing. I'm at 117K and have been running it chipped for the majority of that time.

I recently moved away from a large metro area where the majority of my travel involved highway commuting. At that point, my per tank (hand calculated) MPGs were around 27-29, but I drive with a lead foot. DPF regenerations occurred at a normal frequency and were rarely interrupted.

My new driving patterns are all local in nature, and mostly stop and go traffic and trips that rarely go further than 4-5 miles, maybe 4 times a day. As a result, my DPF regens seem to be occurring once every two days, and are interrupted constantly due to the trip ending. For those that don't know, a DPF regen will only begin once the car has hit full operating temperature and if interrupted, will restart again the next time the car reaches operating temperature.

Of course, given how short most of my commutes are, this means that the car is only coming up to full temp by the time I'm almost at my destination.

The result of this is that I'm constantly running rich (part of the DPF regen), and the DPF is constantly operating. This has dropped my per-tank MPG to around 20 and I've even seen as low as 18.

I know there's nothing wrong with the car, because I can take a road trip and get the mileage I used to get, so this is simply the result of my new driving patterns.


Phew... sorry for the book, but I needed to provide some context for what I'm looking to do, which is bypass/remove the DPF and/or EGR. I have full access to a modern shop with all tooling necessary, including STAR, xentry and autologic. However, I've been unable to find a kit or guidance on what needs to be done to spoof the sensors to make this possible without going into limp mode.


Has anyone been able to successfully achieve what I'm requesting? If so, can you share details? I'm willing to spend money if it means prolonging the life of my car.
