So I had a engine management light come on and have obtained the following codes p3137 & p0642. The engine is a BWA 2006 2.0 TFSI. I think by looking online it may be either dodgy connection somewhere or the flap motor needs replacing. I cleared the codes yesterday and have been driving round town and the light has not come on yet. About a month ago I replaced the PCV with a OEM from the VW garage. Engine wise everything seems to be running fine. Thoughts?
