CEL, pinched hose and 27 mi test drive
<center><img src="http://pictureposter.audiworld.com/110172/rs-4_with_horses_crop_.jpg"></center><p>The EPC light came on late last week. A quick review of the manual (it wasn't the gas cap) and some restarts and it went out but the CEL stayed on. The dealer found a pinched hose under the intake manifold...WTF. It is OK now but had a 27 mile 'test drive'; ostensibly to check the EPC on cold restart. Has anyone else had a pinched hose problem...on an RS-4 I mean.

Pretty certain others have had this problem as well otherwise they wouldn't have made this TSB!
They checked and fixed this for my EPC light the first time. Second time they replaced the intake manifold due to stuck flaps.<ul><li><a href="http://www.jlosee.com/images/RS4/PDF/TSB-RS4%20Manifold-2.pdf">http://www.jlosee.com/images/RS4/PDF/TSB-RS4%20Manifold-2.pdf</a</li></ul>

Lots of CEL threads it seems. Mine actually came on and off the...
...last 2 weeks and it sort of ticks me off. I thought it might be the gas cap (since it went off both times about 5 starts after I tightened the cap), but 2 times in a 2 weeks just seems odd. I've got to take the car in for a mid-interval oil change and DRC check (yes, I'm getting clunking in the front drivers and rear passenger side) so I can't wait to see what they find when then run the VAG tool.
