started up the 3 this morning and it felt really rough. Stared driving and the light came on. It feels really rough and doesn’t gain rpm linearly. Feels like it’s not running on all cylinders, feels sort of like my explorer when it was running on 5 cylinders. It’s at the dealer now, hopefully they can look at it soon. Oh well, guess the M3 is about to get pressed into DD duties.

#BMW Problems

Biggest reason why I was hesitant to get a B58 340i and I why I ultimately went elsewhere.

Fingers crossed that it’s easier than another throttle position sensor.

Glad it wasn’t the M3.

Bimmer guide:

scan with INPA -> look at where misfires are -> plugs -> coils -> injectors -> light it on fire.

5 cylinders? So it’s a Volvo!

Did you scan codes before dropping it off? That can be a double-edged sword, it’s nice to at least know the code(s), but then it leads to worrying about potential 4-figure repair bills.

Coils?

Basically.

Didn’t scan it. I’m sure with my luck it’ll be 4 figures.

All cars have problems, BMWs just tend to be more expensive.

Luckily I don’t have that problem because it’s not turboed.

No idea. Possibly.

Me too, that would guarantee a 4 figure repair bill.

And less expensive.

Hmmm I had a similar problem with my 328i once when I crossed 90k. I forgot the code I pulled, but new coils and plugs took care of it.

Sounds like coils to me. Had the same thing happen the last couple times I had to replace a coil in mine. They are very easy to replace yourself if you have a little extra time.

My E46 did that once, and it was a coil. $125 installed from my inde guy.

Time to trade that time bomb in, no doubt! Can we interest you in a Brand New X7 3.0s2xdrivemsportpackage?

The m3 getting dd duties isn’t necessarily a bad thing.

Nothing like the old M-Tax.

True. Hopefully it isn’t too bad.

Let us know what you find out! I’ve had a phantom misfire on mine, but no codes. I replaced plugs, cleaned out VANOS solenoids, cleaned out eccentric shaft sensor connector.. no change. I believe I’m on original coils at 120k miles, but forums suggest coils either work or they don’t (not occasional idle misses). I’ve been hoping for a code so I can isolate the problem, but might replace all six coils as PM.

5 cylinders is best cylinders. What you complaining about?

Right? Nothing like your car going into limp mode and needing a couple of grand to get it out of limp mode.

The dealer just called, it’s a coil. They recommended replacing all, I was like I’m good I can do that myself.

A friend of mine had an E46 with Volvo/Audi syndrome. It was just a coil, hopefully the same for you.

It’s a coil, they recommended replacing all 6. I was like no, I can do that myself.

At least that is all it was. Simple fix.
