I'm Very curious about diesel tunes (at least low level tunes that leave Emissions equipment in place), but I know my wife will not want to drive a Diesel if it emits smoke from the exhaust, or smells..
So I'm hesitant to even entertain the deletion options..
Wondering if this is a Carbon Buildup related item. Seems like a lot of Carbon buildup related issues on these cars..
EDIT: Found this link ( https://www.bmwusa.com/explore/bmw-v...nty-books.html), which seems to imply that it would be covered under the California Emissions warranty, as this seems to extend to Vehicles in Maryland a a few other states. See what the Service advisor has to say I guess.. |
Glad to hear Maryland is good with that -
but like you said, its the wifes car - you will get some soot, and some diesel stink, when you do the deletes, its inherent nature of the beast once the DPF/SCR is gone -
The milder Stage 1 tunes are able to unlock some power while keeping intact, but you would want to be sure all those components are newer and good to handle the power, because they will fail at some point.
CBU is very rarely seen in the prevalence on the X5D's like it is on the 335D's, something I learned after research, as I was concerned as well - its because the X5's have an additional low pressure EGR, for some reason it doesnt get built up like the sedans with a HP EGR only. I talked to a couple guys recently and one had very minimal buildup in his intake manifold, head looked good, he was at 140k miles. However, some guys with the sedans if leaving the emissions equipment in place report needing full cleaning and walnut blasting of CBU as much as every 40-50k.
Again, if your wife does not want any soot, smoke, or smell, then leave it in place, and hopefully if any components fail they are covered by some sort of emissions warranty...
The CARB warranty is only for cars registered in CARB states, which I am not sure if Maryland is, again, another question for the SA. Also, some guys on the diesel FB group lately of BMW saying certain emissions components are not covered under warranty, yet BMW "goodwilled" the repair on the house. If you have an item that fails and they tell you its not covered under Federal Emissions warranty, get it in writing -
If you have your owners manual set, it should all be in there on the 2013 warranties applicable to your vehicle. Looks like the CARB warranty is much more helpful, since your state is listed.

For someone like me, my wife doesn't mind some soot, smoke, or a little diesel smell (there are downpipes with a diesel oxidation catalyst 'DOC' which help cut the smell down a lot with the deletes, not remove completely, but at least 50-70% of it) - and we don't live in a CARB state where the warranty would apply long term, nor do we have diesel emissions testing, so yes, the logical thing to do is if a high dollar component fails, and BMW does not want to warranty the replacement, then at that time we will go full deletes and not deal with it. There are just so many components of the system added on for NA regulations, that can fail. The M57's in Europe for example do not deal with DEF or the SCR system, they just have a DPF and DOC since they were more concerned about CO2 than us here who were more concerned about NOX.
