    • Fixed my issue. OEM part

Original GM product. Fixed my P1050 code. Make sure to completely fill the def tank before starting. I only put one jug in to test it and it was still saying the tank was empty. Added a second jug and the warning went away. Way cheaper than the $1100 that the dealer wanted for the same part.

    • The product defects are not the sellers fault.
The product which was made by GM failed. Nothing the seller did wrong. The shipping, service, and how the refund was handle were great.
