The parking pawl is just a tiny tooth that fits into a notch in the transmission. It can wear out, it could break, it could just be useless. I good hill won't let it hold. I also hate driveline parking brakes. Vehicles can still move a bit. A proper parking brake is a much, MUCH better locking system.

I understand. I lust after a new S4, but I'm perfectly happy with my 14 year old A4 that runs like a champ no matter how many miles I put on it. Drove through a tunnel with the windows open yesterday and I could gun it in a lower gear without killing myself.

I drove an older one down a windy, bumpy road recently. I hit the bump stops on the air seat so many times! I had to slow down and laugh at how bad of shape that thing was in.

It's okay. Semis are probably the only way I'll drive a stock 600 hp vehicle.

This is why twin-charging exists.

I would think it'd be fine. Here's why: On a track, you would have constant airflow over the catalyst, even if you're driving like a jackass. In traffic, you're gunning it and stopping suddenly. The air around you isn't flowing. It'll overheat. The constant barrage of fuel will have that cat cooking before you know it!

This might happen for me, especially if I can convince my fiance her '68 Cougar needs a supercharger. I know she wants to sand it and repaint it as of now. I need to rewire that damn thing, too. The previous owner strung speaker wire everywhere.

V8? I'm a bit disappointed in that. I was hoping for the inline 5. I guess I'll just have to lust after the next S4 then...

Oh, and taking a DPF to get cleaned costs between $300 and $500 around here. These guys do GREAT work, from cleanings to installs. Obviously all truck stuff.

That article is actually fascinating. I've been trying to learn as much as I can about these as I can. I actually talked to my DPF expert today. He was telling me that the process of cleaning would really only hurt the DPF on a car. They're not made to last. I guess that makes sense. The early aftermarket DPFs for…

All that the process really is is baking the think and blowing it out in an enclosed chamber so the ash doesn't get into the atmosphere. After searching for what they actually look like, I believe it can be done. I've sent out some WEIRD DPFs in the middle of several feet of pipe to get cleaned. If not, I'm not past…

Do I have to?!

DPFs last until they get fucked up by the idiot that continues to drive with a check engine light on or the car having no power. Do you guys seriously not know you can just clean them?!

Uhh, you get them cleaned? It's a relatively cheap process. Do people really not know about cleaning DPFs?

That's really a misnomer. I've only ever had to replace DPFs when a truck shits a turbo and it gets HEAVILY oil soaked. If you STOP driving it like a douche when it has a check engine light or a problem, you won't create the need to replace the DPF. Same reason you don't keep driving a car with a misfire.

Give it an engine with a turbo and AWD and I'll STRONGLY consider it. For cheap, mind you.

I don't know how you missed the memo, but sarcasm does NOT translate into text.

In California, the most stringent of states, older diesels are actually allowed to smoke like that, according to smog laws. According to heavy duty emissions laws, trucks are allowed to have up to 40% opacity, but they should never have more than maybe 5%, unless they have some SERIOUS issues. In actuality, even…

I would love to see one of these with twin turbos.

It's an International. No big loss.
