104/106 Error

[topazblau]

So Ive been getting a 103/105 error code on INPA ~a month after rebuilding my vanos. Prior to taking it to the shop, the car would rough idle and go into limp mode at a red light or stop about once a day every couple days.

Shop replaced the vanos (via dr vanos) just to rule out all issues and as soon as it was replaced; it now throws 104/106 for the exhaust side. Its been there for nearly 3 weeks now and they seem like they don’t exactly know what’s wrong. However the car drives normally.

Could this be an error with the vanos install or a faulty system? Im basically walking on eggshells waiting around for my car just trying to guess what could be wrong.
