Q50 Limp mode on acceleration ? -
01-13-2022, 03:43 PM
soo its been days of me trying to get this JB4 to work. ive had it down to where it drives fine for 50 miles in the morning and then after work on the way home im stuck in limp mode till i unplug the JB4. P0234/36 i believe is the codes. and while watching the JB4 app i can see the boost just max out to 20+ PSI and im in limp mode and then the car shuts off of course. Any one else have similar issues or exact ?

Sorry for tech support you really need to email us.
I'd guess something is defective here with the JB4 harness. Send it in and we'll test/replace it for you.
