Hello,
I can't find anyone talking about the p0103 code and the n54, I'm assuming it's because the n54 doesn't have a maf
But I have an n54 and a p0103 code.
What should I try? Cleaning the map?
Story:
On the way home, on the highway, I started getting what felt like a miss under load, clutch in and it reved fine. No codes or triangles. Near home, looking for parking, I had the the "engine malfunction reduce power" come up. Parked, turned it off and back on. The engine malfunction came back on after a few seconds and a check engine light(p0103)

Thank you for reading,
Morgan

 

I do think that the n54 has a MAF and the p0103 indicates that the input from it is high. Check the MAF, it possibly going bad.

 

Check vacuum hoses before trying to replace the MAF. Could very well be a leak from a small hole

 

Wonder where they hid a MAF on the N54. I've been all through mine and never found one.

 

I said MAF earlier meant to say the MAP. The N54 does not have a MAF.

 

Thank you for all the replies. I'll check the vacuum lines going to the map

 

You have the N54B30A engine. The part you have is the Intake Manifold Absolute Pressure Sensor (MAP Sensor) 13-62-7-585-492

 

Cool is it cleanable or just replace it? (Still gonna check vacuum lines)

 

I had forgotten that N54 doesn't use a MAF meter to measure air mass flow, but simply air pressure which inputs to a PID controller (Proportional,Integral,Derivative algorithm) to calculate air mass flow and control the fuel injection. Therefore the air pressure sensor (MAPsensor) is what I should have referred to. It is possibly defective. I think that you know where to find the MAPsensor.

 

Yes you can clean any sensor. But make sure it's the issue before you replace it.
