Title: b5s4 DTC 16490/16622 Post by: crash on March 30, 2013, 09:50:58 PM I'm new to this posting thing so cut me some slack
I know what the codes are. and this is what I have done so far VAG. group 115 840 rpm/ specified boost 1010mb/ actual boost 1380 that's over + or - "tolerance" I checked charge air line's no leak's , vac. line's are fine, n75 fine, dv's are fine waste gates crack @ 12 psi. like they should. checked the MAP plug w/voltmeter it starts at 5v and cuts to 3v as pressure creeps up to1380mb MAF readings are fine. WOT. run it doe's not over boost it spikes @24 and tappers to 22-23 like always but it cuts @ peak boost request 2800-3000 rpm I don't want to throw parts at the problem is it the MAP ? I don't think the MAP regulates psi it just monitors psi ??? Thanks Some info on the car EPL tune and fuel kit franken's 3"downpipes no cats awe twin II |
