Ok I was driving going about 15mph when I all of the sudden lost boost and I quickly pulled off the road. My check engine light was on
and I could tell that my exhaust sounded funny. At first I assumed My turbo went out but my turbo only has about 15,000 or so miles on it and it is a sealed bearing turbo wich from what I'm told last longer and have less problems. let me add that I am a beginer at Audis and this is my first It was the MB QUART DEMO CAR and everything was upgraded and I can't see any hoses that came loose or are broken So I need some help please HELP I just put the car in the paper for sale and the next day I loose boost I only have 39,980 miles on it
The car is a 2003 1.8t quattro thanks for any help. that will save me money lol....

 

possibly if you engine light came on and you turned it off right away, but heard weird noise from exhaust that it is a bad coil...... might wanna vag it or get it scanned
