Hello, I bought this car about half a year ago and I’ve been having my engine light come on and off for the last month aswell as the slip light sometimes , when I scanned with ob2 pa0068 code comes up, and it seems to have a rough idle.  I am going to have a look at the throttle body at the weekend to check for dirt and grime. 
 

My query is about the photo , I bought it and did query the pipe that is  stuffed in the photo bu Didn’t really get an answer and had no issues for 2/3 months. 
the problem seems to go away when I press the pipe in more so it could suggest a loose clip or need changing. The issue is I don’t even know what the pipe is or why the material has been put in there , and my other query is would this be affecting it to trigger my engine light.

Lots of things can trigger waring lights and error codes for lots of reasons with the engine but given all that tape and that things get better when you pushh the pipe see the link below.

 

You might already know and be practicing the following, when using a scan tool it does need to have a program for your model and year and that program does want to be fully up to date before you use it on the car and you want the car's battery and scan tool battery if appropriate to be at a reasonable level of charge for all the testing period (and beyond for car). 

 

As for slip light (?wheel traction?) that could be an entirely separate fault or the VW computer programs getting their panties twisted.
