I've been Cobb tune for about 12000 miles and recently developed a P0035 hard fault. Running stock bov, checked connections no issues. Checked iat connections no issues. Wastegate is functioning, no power loss, looking for any folks who had similar issue?

P0035 indicates an issue with your Turbocharger Bypass Valve Control circuit. Possibilities are a damaged bypass valve, open circuit, or circuit shorted to voltage.

Well I figured it out hope this will help someone else in the future. When you install the cobb intercooler you reroute the wires to the wastegate and bypass valve. I thought I did a good job and had strain relief, zip tied securely etc but one wire broke to the by pass valve read at the connector. Fortunately I have a weather pack crimp kit lol.

Hi guys im new to this forum can someone please help me i got a p0035 code the other day while towing an empty car trailer, i replaced the oem bov with an em bov still getting the same code i removed the svt tune thinking there was corrupted software, of course svt was closed for me to ask for assistance, i checked the voltage at the em bov after this and am getting 15v i also have an add bumper installed, it was installed prior to purchase, i noticed some people on here saying they were getting that code after install, im totally at a loss and don’t want to drop thousands just replacing parts. This is my first vehicle with a turbo so im new to this. Its a 2018 has 60k on it svt tune , cai , and exhaust done. I did notice one thing while driving cross country during thanksgiving, svt corrected the tire size to match the speedo but when driving home noticed that the speed on the dash was not the same as the speed on the gps the speedo read faster than i was actually driving as per gps. I don’t know if the code could be related to the tune but just found it weird that now i am having problems any help would be really appreciated im not sure what to do now and can’t bring it to the dealership since it was tuned and they will see the different parameters that were set before i removed the tune. I really need help getting rid of the p0035 code
Thanks in advance guys oh also had to hardwire the em bov due to the clip breaking when i was connecting to factory clip
