Just replaced plugs and coils and now have a reoccurring code

SnapCoupe · 03-19-2018, 11:46 AM

Friday night I replaced my plugs and coils on my 2011 335i with 83k miles. All of my mods are in my signature. Car has been driving fine since, but keeps throwing a SES light due to an active DME code along with a shadow code.

The active code is 28A0 - Intake pipe absolute pressure, plausibility: pressure too high.

The shadow code is 2820 - Absolute pressure sensor, intake pipe: multiple fault.

I did have to remove my intake and unplug my MAF to do the job. Would these codes come up from anything that I had to remove and reinstall? Are there any vacuum lines that are hanging around the topside of the motor that I could have potentially unplugged? Trying to get some insight before digging back in there.

Thanks!

IMHO

As long as the car is driving fine, I'd clear it and see if it reoccurs.

But yes, this *could* relate to intake or charge pipe.

Sounds like something is unplugged or leaking. Presume you checked all connections and connectors on intake and chargepipe?

It has popped back up 3 times after clearing it. Also sprung a SES light once.

During a smoke test I performed a month or so ago to fix a boost leak near the intercooler, I noticed a bit of smoke was coming out of the engine side of the CP. I replaced the gasket in the CP, but it did not fix the leak entirely. It hasn't caused me any issues or popped any codes so i'm assuming that isn't it.

Any updates?

I also have 28A0: Throttle-valve angle - intake-manifold pressure, correlation: Limit value exceeded and it is throwing causing my SES light to come on. I replaced cylinder 1 coil after a misfire.

Code went away after a week of driving. Motor spun a rod bearing yesterday though, and now I need a motor. I highly doubt there is any correlation though.

Did you end up getting new motor, SnapCoupe ?

I'm getting these codes.....

I'm worried

Yeah I did, but it had nothing to do with the codes. I had a loose generic aftermarket chargepipe that didn't fit correctly, which I am 99% sure was causing the codes.

Gotcha. thanks for replying! Mine went away after an oil change and cleaning the MAPs and MAF (kind of) lol

Make sure ur intake pipe is all sealed. Clean MAF.
