[QUOTE="KevinO, post: 5950, member: 3059"] P0299 is turbo underboost and P05A1 has to do with the active grill air shudder position sensor. This grill is in front of the intercooler. Underboost could contribute to a problem with the BOV but reinstalling the OEM unit should rule that out. From what I've seen, installing the new IC required removing and reinstalling the active grill. I'd look to see if there is anything interfering with the movement of the grill's shudders. P05A1 could indicate they are not at the commanded position. It sounds like you are able to replicate the errors. Set your dash up to show boost and make note of the boost when P0299 hits again. Or use a logging function like in Dash Command or other similar apps to log data as you drive. It'd be interesting to see if boost is truly dropping. [/QUOTE]
