Hello, i have adblue issue on my car, i get both adblue and engine check errors at the same time. they both come and go. i did check under the hood and saw crystalized urea built up around adblue injector. im wondering should i pay for replacement injector or is it factory error?

Could be simple, but would need you to post the trouble codes for us.

Hello!

This could be something simple as DEF/AdBlue needing to top up.  
Did you check the AdBlue level?  
Also, failed in-tank heater is a common cause, as well.

Hope it helps.
