2000 audi a4 quattro code po238 help please!
i just chipped, changed the dv, and put a boost gauge into my audi. the code is for the map sensor, so im wondering if it couldve crapped out or one of these things caused my problem. My car boosts fine to 15 pounds first 3 gears, but when i try going in 4th over 3000 rpm, it overboosts to about 18 pounds and surges bad. could it be a boost leak from the boost gauge? maybe i got a bad dv? or does it sound like a map sensor problem?
