Cel With No Code

[Bmx537]

Hey guys, picked up my m35 on Friday night. So far I've just chucked a pod filter on it and block the BOV. After an hour or so of driving it threw up the CEL. I pulled over straight away and had a look around. Couldn't find anything. Also seems to be driving as normal. I read somewhere that they go away after a while if you had the AFM unplugged. It's been 2 days now.

All the research I've done shows it usually flashes an error code too, mine does not.

Anyone experienced this or no what it could be?

Thanks!

It wont just flash a code, unless put into diagnostic mode. Which I don't know how to do with an m35.

Pod filter why?

Guy I bought it off gave it to with the car. So why not.

Makes a nicer intake noise at least.

If you unplugged the AFM with the ignition on; it will throw a CEL.

It doesn't flash, you have to put it in diagnostic mode to see what the code is.

Do a search and look for CEL reset NM35; this will show you how to clear the code.

The stock airbox is good for more than 350kw; all you are doing is making noise and going slower. I don't get why anyone would do that.

Blocking the BOV isn't a great idea either, but that seems to be the direction of your "mods" so far.

Welcome to the forum, enjoy your NM35.

Thanks mate! I'll check it out.

That's good to know about the airbox too, think I'll be chucking it back in!

You may also find the code has thrown due to blocking off the bov. The afm actually expects to have that air coming back at it. So without that recirculated air it could be freaking out

Yeah that's what I was thinking.

Cleared the engine light, took it for a decent drive and hasn't come back on.

Might be from when I had the AFM disconnected.

Thanks guys.
