Hey all!

Bit of a strange issue. On my b6 A4 1.8t (running a 518ak file), I ran an auto scan the other day just because it's been a while and I came up with some injector codes? The cars been running completely fine so I'm not too concerned but I figured I'd see if it related to my tune.

The injectors arent stock, but they're OEM for the AWW mk4 Jetta. Got them for free and they're 319cc vs my 282cc stock injectors. And have over 100k less miles so I swapped them out.

 In my tune I simply checked my buddies stock tune (he happens to also have an AWW mk4 with the same injectors), and copied the values from TVUB and KRKTE. Could that be why I'm getting this code? I've been driving for probably 6+ months since doing this with zero problems.

Thanks for any insight into this! Picture attached.

P.s. sorry I was in a rush so I simply took a picture of my laptop instead of screenshot.
In case the "screenshot" is crap:

17645 - Fuel Injector for Cylinder 1 (N30) Open Circuit
P1237 - 004 - No Signal/Communication - Intermittent

P.s.s. I had a compustart remote starter installed a few weeks ago. Could the start up process for it be causing the problem? I'd find that strange.

Definitely not related to tune. Hardware/electrical problem.

Have you ever done an oil change and pulled the injectors to let it build pressure first?
