p1ce7, p1ce6, p1ce8 are just some of the codes some other aftermarket air intakes will throw. This is often due to the vacuum pressure being lower than anticipated at WOT. While these codes are generally harmless and just indicate some values are outside of what the ECU thinks they should be our customers wanted to not have any codes so we redesigned our air intakes accordingly and are providing free plus shipping updates to everyone who has bought an air intake from TunedMercedes.com in the past.
