My 04 545i is now running real rough. Started with just the odd what sounded like a miss fire when cold a couple a weeks ago and would soon come right and idle smoothly. Now it's constantly running rough, not 100% if it's a misfire, or running on 7 or what. I have tried cleaning the mass airflow sensor as one thing I might be able to do but made no difference.

Any thoughts or suggestions greatly appreciated. I'm in Dunedin, if anyone here would be willing to help, yarn or suggest someone who may be able to help that would be great. I have just bought a K+DCAN cable to have a crack at trying to work out what might be wrong, but need to work out how to use that first too.

Cheers Sam

So Installed some software and plugged laptop into car with trepidation and got the following codes, screen shots etc. Any help deciphering this would be great.

Maybe O2 sensors and a miss fire on 6 and 8. New coils maybe??

Open them up and check the condition. I would do all of them and know they are all good than fix a couple to have a few more fails a month later.

it's the gehberhrenschitver valvugolpen. it's gefingerpokened kaputzezechtenarbened.

Assume the position and open your wallet, buddy.

/serious mode on

Kyu's analysis seems reasonable place to start.  What's a set of coils for the N62 worth? Oh, under USD200 for the new Bosch design, seems reasonable.

Definitely no vacuum leaks?  And your battery is strong and tests well yeah?

cheers

Cheers, SuperCheap auto have coils and plugs for $1250, anywhere do it better than that, seems pretty high or am I just really naïve, ignorant and cheap? probably all three.

I'm no mechanic or fool, but with a few YouTube vids are they easy enough to replace yourself?

Cheers

Not sure on vacuum leaks, had a good look around engine but don't really know what I'm looking for, assume battery OK.

yeah Supercheap and Repco are good for oil, car care, and running your Holden or Falcon.  For your Euro, you'll need a specialist supplier.

First stop should be the forum's supporters/sponsors.  As you're in Dunedin, you should try Milland.  http://www.milland.co.nz - and they're right there in Dunedin!  Euro Itallian are also said to be very good.

I've often used www.fcpeuro.com - started buying parts from them 12 years ago soon after buying my Volvo.

Seriously though, give Milland a call.  You may find they have what you need at good prices.

Hope that helps.

Yea cheers, ashamed to say I forgot about them and they're maybe six blocks away, although only on line. Used them a few years ago with E39. Thanks for reminding me.

fcp euro is cheap and quick (1 week delivery) and you have a range of different OEM or genuine to choose from at varying price points.

Spark plugs i paid about $50nzd for a set of 6 ngk branded ones whereas locally they were about $35 each.

K&G McCloud up Waverly is the place to go with euro stuff. Bmw send a lot of stuff up to them. They'll be able to diagnose the issue without throwing money at guesses to what it could be. Did it come with much of a service history?

Cheers, I just dropped it to my local garage on Hillside Road, will see what they say on Monday. Will keep K&G McCloud in mind definitely. Has service stamps from new, no information just that it's been done, have thought about trying to get history from previous garages up in Christchurch.

Something you will learn quickly with a BMW, is that unless its a basic oil change, taking it to your "local" isnt always a good idea. A good independent BMW specialist is the way to go. It may cost more in the hourly rate, but itll make up for it with a more accurate diagnosis and knowledge.
