What could this be?

Hi everyone... 2010 A4 Quattro, 2.0T. 109k miles.

while driving recently, car has been shakey/running rough. Not horrible, but not smooth. Check engine light was on, throwing a code for intake system leak.

Just yesterday while driving, (still not smooth) I got a warning low oil pressure, turn off engine. I parked the car and shut it off.

When I started it today, the check engine light was still on, it was still running rough, but the low oil pressure shut off engine warning was not on. It came on the first time after about a half hour of driving, so it's possible I didn't let it run enough today.

Does anyone have any idea where to look? Thanks in advance!

Could be a few things. Has it had its pistons and chain tensioner replaced? Low oil pressure is generally very bad news.

No, it has not had those replaced...

Do you have access to vcds? Your car needs to be scanned for codes.

I have a cable and vcds lite. Will the lite version be enough?

No clue. Try it.
