Crankcase fault code

I've randomly checked codes with Carly and have the following code pop up -
INFO 20E121 - crankcase ventilation 2 vent hose no connected/ defective.

No CEL and car drives fine.

Any suggestions?

Clear it and continue living life. :-)

If you're curious, you could inspect the PCV hoses that go from the turbo inlet to the valvecovers.

Read codes again after a week or so of driving (depending how often and how far you drive).

I should have said. The code won't clear. Have examined hoses and all seem fine.

Ah, that makes a difference then. Hmm. When you try to clear it, key on, engine off. Does it come right back even before starting the car? If so, it's a hard fault that must be related to a sensor somewhere.

I had this code a few years back. I ended up cleaning my MAF's. It's worth a try
