Alright, to start. I made a previous thread about getting a code about 10 minutes into driving saying "Service Needed" and "ASC OFF". I thought at the time it was due some recent changes on the car. I changed the lines from the wastegate solenoid to the AEM intake i had on. I recently returned the the intake to stock. The only mod i have is a Invidia long DP, and Invidia N1 CBE. This code thing has been going on for about two weeks. Today was the first day i have had off from work that i could handle it. I have been driving like a grandpa

Alright codes in orders from which the Snap on tool read them:

U0401 - Engine (Can Message) - Engine Data Error
u0431 - ETACS (Can Message)
U0100 - Engine (Can timeout) (2X)
U0141 - ETACS (Can Timeout) (2X)
C1617 - AWC Can (Main) Data no reception
C1290 - Fail Safe Mode (Loss of Can Data)

Ive searched a little bit and the codes seem to have no definition. Any help would be awesome. I was thinking about going to grab an Accessport and doing an OTS tune to see if it helped. But need to get the opinion from the experts. I will also remove the Downpipe and go to the ****ty local dealer who nevers helps
