“Service DEF System See Dealer” (Now What?)

At Geno’s Garage and the Turbo Diesel Register (TDR) we’ve seen and written about problems with the truck’s diesel emissions fluid (DEF) system. From these articles the majority of problems were caused by a clogged DEF injector.

The message that shows on your dashboard, “Service DEF System See Dealer”
Ouch, is this going to be inconvenient and expensive?
Maybe not.

Here are your options:

1) Self explanatory “See Dealer.” Bring lots of money with you.
2) Remove, clean and replace the DEF injector as described in the TDR (see below to read).
3) Remove and replace the DEF injector (Mopar #4627241AE – 2013-2024 Ram Cummins Turbo Diesels).
 
In the past, the only cost-effective option for the DIY-owner was Option #2. However, with the Geno’s Garage BE PREPARED SPECIAL, the Mopar DEF injector for 2013-2024 Ram Cummins trucks is offered at an excellent price of $95.95 – versus the MSRP price of $253.95. The DEF injector comes with two Mopar bolts in case they are needed – though not all model years used bolts.

This makes Option #3 your best choice.
 
PLAN OF ACTION
Seriously, be prepared. Read the articles linked below.
Replacement is very simple so you can select Option #3 and have a spare ready for service.

* ONLY WHILE SUPPLIES LAST! At this blog post’s publication time in May of 2024, we have an overstock sale going on with New Old Stock (NOS) Mopar DEF Injectors for 2013-2024 Ram Turbo Diesel Trucks.
