Vacuum Leak?

Vacuum Leak?
My 2000 A6 2.7T keeps indicating a problem with the engine (dashboard indicator light showing the engine with an electricity symbol over it). My mechanic plugs in his diagnosis tool and it tells him that the car is suffering from a vacuum leak on both banks of the engine. Having investigated the apparent problem at great length, both visually and with a smoke device, he can find no such leaks. He has re-set the computer several times and all is well for a few miles, after which the light comes on again.
I don't want to go through the process of buying numerous different parts until I find out what is wrong and I'm hoping someone may have had the same problem and can lead me to the most likely cause/solution.
Thanks

RE: Vacuum Leak?
I don't recall the codes....but if it was lean codes on bank 1 and bank 2....... a MAF took care of the problem for me!! but of course make sure that you check ALL of the vacuum lines and intake boots first!!!
