The car is an RS6 Avant Quattro for 4.2 Biturbo with exhaust, turbos hybridized, filters and ECU MTM 570 - 580cv.
Well the fact is that a month ago I had problems with it and finally got it repaired, beginning to put him on Vagcom I got these errors:
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 001 - Upper Limit Exceeded
16688 - Cylinder 3: Misfire Detected
P0303 - 001 - Upper Limit Exceeded
16692 - Cylinder 6: Misfire Detected
P0306 - 001 - Upper Limit Exceeded - Intermittent
16487 - Mass Air Flow Sensor (G70): Signal too High
P0103 - 001 - Upper Limit Exceeded - Intermittent
17482 - Mass Air Flow Sensor 2 (G246): Signal too High
P1074 - 001 - Upper Limit Exceeded - Intermittent
17963 - Charge Pressure: Maximum Limit Exceeded
P1555 - 001 - Upper Limit Exceeded - Intermittent
Readiness: 0110 1001
I did this .... chooses to look coils, MAFS, and the sleeves of the Turbo IC, what was my surprise that when removing the coil No. 3 spark plug was loose, so review them all, and all loose.
Change the 8 spark plugs, as they had not NGK put brand BERU, look at the MAFS and No. 2 had a broken wire, fix it, look at the sleeves and one of them badly fucked with the flange to point out, you change the flange and got to the site. With all this the car was like a rocket, no problem yet when I gave the volatility marked the two MAFS, but going well.
A few days ago began to backfire again (fake explosions at full throttle) and only gave me both error and missfire MAFS, this time in cylinders 4 and 8, so choose to change the 2 MAFS with the hope of ending with the problem ... but has not been so the car is better but still fails when accelerating hard ... Sometimes it is like without blowing two turbos and I'm still checking these errors:
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 001 - Upper Limit Exceeded
16688 - Cylinder 4: Misfire Detected
P0304 - 001 - Upper Limit Exceeded
16692 - Cylinder 8: Misfire Detected
P0308 - 001 - Upper Limit Exceeded - Intermittent

P1074 - 001 - Upper Limit Exceeded - Intermittent
17963 - Charge Pressure: Maximum Limit Exceeded
P1555 - 001 - Upper Limit Exceeded - Intermittent
I have deleted everything, I checked the hoses were not loose the 2 MAFS were ok, and I gave a lap, after lap I check this:
5 Faults Found:

I'm going to go crazy, I'll look coils and spark plugs, BERU spark plugs do not give me confidence, I will put the NGK.
I also thought that the explosions are false for the fuel filter, could be relevant for the gas pump?
The MAFS could give me some tube failure on the N75, or the N75 that is broken or because the ECU TUNED not well, I thought about going and put a REVO stage2
once again sorry for my English...
