F30 328d xDrive Coal Switch Question
I'm familiar with pickup trucks that add coal switches and wondered about cars doing it. I have seen a lot of high performance diesel cars that do it but I've also seen some stock VW diesels doing it. Granted it does not produce much smoke for such a small car but it does increase your launch speed and adds some Power. Has anyone attempted this modification on a BMW and would this void any manufacturer warranties or cause and error codes?

It will probably ruin the whole car, given at how sensitive the emissions system is, along with many other things. You are aware of what "rolling coal" actually is aren't you? You're not gaining any power from it, and you are wasting more fuel, along with the very good possibility of ruining the heads on it.
If you are looking to add more power, there are 2 different options for the US 328d to my knowledge. There is a bench tune out of Canada that requires you to send your ECM to them, or there's a piggyback from Dinan. Both will yield you almost the same results as far as max power outputs go, but the Dinan is reversible and removable if any issue comes up. I will honestly say, if you bought the diesel for the sole purpose of rolling coal, I believe you may have bought the wrong car. |

I do also realize there is a dramatic difference between the diesels in trucks vs cars and also the transmissions moving them. Just wondering if there was anyone else that experimented with this.

All the trucks that are rolling coal have had DPF deletes. Rolling coal on a 328d will just plug up the DPF: if a regeneration won't clear the excess, then you're faced with a $2500 replacement part.

For bench tunes FixMyVW in GA does the JR Canadian tune in the US. There's also Mission Performance in SoCal. |

"rolling coal" doesn't actually produce more power, it literally dumps power out the tailpipe unburnt. That thick black smoke is unburnt fuel and particulates from running too rich.
you can delete the DPF on these cars completely, and if tuned correctly you still get almost no smoke at all. |

I didn't say you "can't" do it, I said you can tune the car correctly to keep it from smoking excessively and still provide more power. "rolling coal" is nothing more than blowing money out your exhaust, and is quite honestly an idiotic thing to do...

Why not tune it correctly to burn the fuel more efficiently thereby increasing power? Quote:

So, basically, your 'how to look cool' is to throw out loads of black smoke, which contains carcinogenic particulates.
Nice. There's a word I'm thinking of to describe you. Starts with a W, ends in -anker, and rhymes with 'banker'. Can you guess what it is yet ? |

Second, It produces less power than a properly tuned car, wastes fuel, and pours cancer-causing chemicals into the air. Strange why people wouldn't like it, right? Quote:

Also, the whole "rolling coal" thing is the reason why we have to have all of the emissions stuff on the car in the first place, and is part of the reason why diesel generally gets a bad rap (before VW went and finished it off) if you were to go to Europe and see just how many vehicles over there are diesel, you'd really be amazed. BMW alone has offered in the past a tri-turbo inline six diesel, which has now been given another turbo. Will we ever get it? No. Why? Rolling coal fans for starters. Followed by all the green people who have all but killed the diesel car market in the US because of the rolling coal fans. Hopefully GM will be able to somewhat bring it back with their entry level diesel cars. |

I think it was a V6 actually. The R10 and R18 were the race cars, but I forget what engine was in them. In any case, it was more of a loophole in the rules that they exploited. When the rules first came out the diesels in the same class were allowed to be much larger displacement and run higher boost. Because of that the rules also allowed a larger fuel tank. Guess what? That was a recipe for running a high powered diesel. The only regulation added was that they could blow any black smoke (very appropriate for this discussion)! Audi doesn't run in Le Mans anymore, but they dominated the class with their diesels for awhile, but the rules were different between gas and diesel engines. If everything were the same, they probably would have run gas engines.

I mean, if you're such an expert, then why on earth were you on here in the first place asking advice ? Go for it. I can't wait to hear about your EGR failure (and you can't code those out or blank them off on the Fx cars, unlike older diesels), and high levels of soot and unburnt fuel WILL lead to rapid EGR failure. Can't wait to hear of the injector failures, or the car attempting to do active regens due to the soot levels it's detecting, and that leading to raised sump oil levels and an engine runaway, which (2 minutes later) leads to the engine bouncing off the rev limiter until it self-destructs. After all, you're an expert, right ? You've watched a couple of youtube videos. Fucking muppet. |
