Can you see the WG actuator actually cycle and move? Maybe the actuator is bad? Maybe a bad or not plugged in pressure sensor?So my buddy just got a 2021 XRS. It has 15 miles on it now. It throw a P0234 overboost code. I looked at the Wastegate solenoid and everything looks to be OK no cracks all lines are good. I try to clear the code but it won't clear. He said it has never had any power. It's like its in limp mode but it not displaying anything on the dash.
Does suck that the new ECU can't be communicated with the existing aftermarket tools. Likely clearing the code after correcting the leak would fix the issue. Does the 2021 have the ability to read and clear it's codes?After looking to find the problem. I found the charge tube was off just above the throttle body. I put it back on and also tested the wastgate actuator with my mityvac, opened at 9psi. Took it for a test drive and now its making boost but soon as the boost comes in something cuts power. Still has the P0234 code that I can't erase.
Dealer said only the BRP scan tool will erase it. I tried my MaptuneX on it but it won't on the 2021
