JB4 Codes

carbon428i · 02-06-2018, 06:32 PM

Should I be worries about these codes? I'm running Map 2 with the only upgrade being VRSF DP and running 93 pump gas.

Codes:

152D08 Knocking - Injection system shutdown
152408 Super knocking cylinder 4: Injection shutdown

I'd be worried if I saw anything that had to do with knocking.....

Just my opinion though......

Absoluyely, I would be worried. Anything with knocking is BAD. it's detonation or there is something wrong with the air/fuel ratio. Are you throwing a CEL? Have you tried turning the JB4 off or disconnecting it?

Yes, knocking codes are bad news especially on the N20 that is known to have weak pistons.

Mine is a N26 but I'm assuming it's the same? What do you suggest I do?

I'm not receiving any CEL. I haven't tried turning it off and would prefer not to disconnect it, can i disconnect it by putting it on Map 0/4?

carbon428i · 02-07-2018, 09:44 AM

Let me also add that my clamp connecting the DP to the midpipe broke when it was being installed and I'm waiting for the new one to arrive so there's a bit of a leak in the exhaust. Can this be the cause of it?

MONSTAR · 02-07-2018, 12:19 PM

I got the same codes AFTER the install of my downpipe (only map1). I replaced my spark plugs with M3 plugs and it seems to be fine since. It may have just needed a spark plug replacement but the 1 step colder plugs couldn't hurt with the additional boost. This was at around 50k miles

EDIT: if you do some datalogging you can post on n54tech and they will help you out

Can you send me a link to where I can buy those M3 Spark Plugs? I don't mind replacing them i just want these codes to go away.

I bought mine from a BMW dealership on ebay for $75 for the set of 4. You're looking for part # 12120039634

carbon428i · 02-07-2018, 04:05 PM

Will this 100% fix the issue? Is there a known fix for this?

Diegov209 · 02-07-2018, 05:04 PM

I think you can at least start diagnosing the problem on Map 0, but I'm not certain. If you still have the message, you may want to disconnect, just to see if it has to do with the Tune.

I seriously doubt that it has anything to do with the exhaust mods. this should all be about Fuel and air. Spark plugs, combustion, running lean... whole number of things.

You may want to bring it up in N54Tech also with some datalogs if possible.

carbon428i · 02-08-2018, 01:44 PM

Quick Update: I ran the car on Map 0 and Map 4 for a two days and every time i clicked read codes the same codes came up. I'm not sure if the time above the code means when the code came up or when i checked for the code but after i hit clear codes and then checked for codes again, I got "No Codes Found". I'm not sure what I did or if maybe I was pushing too much boost, but I'm gonna run on Map 1 for a few days and see what happens.

He recommended fix the exhaust leak and then check again if there are any codes, which I told you after it was fixed the codes went away. Check to make sure your AFR is normal. Take some logs and either post on the N54 forum or BunkerJ can take a look at them for you.

Yup! If anyone needs me to, I can take a look.

rjd_F30 · 07-21-2018, 07:17 PM

Sorry to bump an old thread, but carbon428i and Diegov209, did you guys find any fixes for these codes and/or did the colder plugs work? I have the exact same codes as described in the original post directly after a DP install (still on Stg. 1), kinda worried. During a WOT the car did pop once like Diegov209 described. I'm totally wiling to get colder NGK plugs if that will fix the issue. Any updates guys?
