I have 6k miles on my N55. My engine mods are Stage II for two months and a BMS downpipe which I've had for two weeks. All has been great! Tons of fun.

Today when I turned the car on the engine light came on and said "engine malfunction. Car is drivable at reduced power".

I parked the car and came back and the engine "logo" wasn't illuminated but it said "get engine serviced soon".

Any ideas. I'm going to take the car to Matt at camber toe tomorrow but I'd appreciate your guys' expertise also.

Thanks

Any time you get check engine light (yellow half engine or reduced power indicator) or service engine soon light (orange SES) the first step is to read the codes. With a Stage2 installed there are two methods. The easiest method for beginners is to connect the laptop interface and use the "read codes" button under settings. This will give a full listing along with descriptions. Alternatively for more advanced users or if a laptop isn't available you may use the in dash reading on menu 1 option 1. Directions for that method are here:

If a Stage2 is not installed you can also use a BT or CT tool to do the scan. Once you have the exact code details email those in to BMS for advice.

Ok... So I just went out to my car to check for codes. I had switched to map 0 so I switched back to map one. No check engine lights or service lights anymore. I then went to see if there were any stored, there weren't.

I am happy yet nervous

What would our next step be?

Wait for the code to come back up and when it does switch to map 0 to prevent the autoclear from deleting it. Then read the code.

I disabled autoclear. For now at least.

That is fine too. With autoclear off you'll get all the tuner codes (2774, 2C90, 2C58) and then also the 3106 catless code. So you ignore all those and try to locate the abnormal code. Best thing to do is to engage BMS for help. They've tuned around 10,000 cars and have seen it all and are well equipped to help you. Normally posting for help on the forums just results in bad or confusing advice in my opinion.

I didn't want to bother you guys if this was a routine run of the mill thing.

Thanks mike
