in a world of hurt... help diagnose codes

[Chewyjr15]

picked up my car from the body shop today drove it off the lot, hit the freeway and gunned it i hit 80 mph and it felt like i hit a wall. instant light on my dash engine malfunction reduced power. I limped it home and ran a scan heres what i came up with


30ef glow ignition cylinder 3
30f1 glow ignition cylinder 5
30f2 glow ignition cylinder 6
30ee glow ignition cylinder 2
30ff exuast fume turbocharger low pressure side
30f0 glow ignition cylinder 4
30ed glow ignition cylinder 1


manipulation code 2d18
2aaf fuel pump 3 evens in the last 20 miles

2f9a outside temperature sensor communication
3 events in the last 20 miles

What was getting done to it in the body shop?

Looks to me like something was left unplugged, or a hose wasn't connected properly maybe.

i read ended someone maybe they didnt tighten an intercooler clamp or something? what should i do???

[jeremyc74]

Do you have a tune on the car? If they get in there and start poking around, they're very likely going to give you shit for the O2 sims, even though it's got nothing to do with the issue.

I'd go out and start it up and get under the hood and see if anything sounds funny. It's very likely an issue caused by the damage that was repaired. That outside temp sensor is probably up in the nose somewhere, so maybe it's shorted out and causing strange things to happen.

i went out and tightened everything down and it still did it, i switched it to map 5 and it stopped. Maybe cause i have catted dp's. It was hesitation on map 6. I rest everything and will drive it tonight on map 5 than rescan ill let you know how it goes.

What if you switch it to map 0 to turn ther JB3 off? Should not be getting codes at all if everything is good.

[Chewyjr15]

thats what ima try next

[MrRoboto]

remove tune, clear codes. If they come back go to dealer.

i was very low on fuel when it happened it said 10 miles to empty. IIRC there was a thread a while back about this happening when below a quarter tank of fuel. So ill see i reset everything and will keep my eye on it, knock on wood it hasnt happened since i tightened everything and switched to map5.

Go to www.n54tech.com

in the 135i section they have a sticky which explains some of the codes. it is still very much a work in progress thing with only a handful of code definations but you may get lucky.

i lowered the boost levels and it went away, according to what i read i should not run map 6. To much boost not enough octane. It was engine knock. And possible a boost leak.

thanks

Yikes, don't race your car like that with 10 miles left. Maybe ran it out of gas a bit at WOT? Would explain all the codes. Assuming the mileage on all of them correspond to that one event.

I think you should only run map 5-6 when you have at least 93-94 octane gas and other mods like intake and downpipes..

[The Cthulhu]

Yes, from everything I've read on timing/knock, those are some serious knock codes. Scary!
