Emission warning

[hornmeister]

So Friday driving home from work the Emission warning light came on on ignition of my 2013 GTI. Checked in for a look at VW on Wednesday. Light has since gone off a couple of journeys later but still going to get it looked at.

I had a turbo pressure sensor go a few months ago which intermittently put me in limp mode but other than that I've not experienced any issues like heavy oil consumption. The acceleration has been a little lumpy especially at slow speed intermittently for a while which may be a factor.

I'd appreciate any thoughts people have?
