With 75,000 miles on my F350, I started having occasional check engine lights, even though the truck seemed (with one exception) to run fine. The light would go out by itself after putting a diagnostic tester on it. Each time, the code was P132B. When I took it to my Ford dealer, a more thorough test showed a P0402 excessive EGR system flow code as well
The exception occurred on our recent Colorado, when the cold engine stumbled for a very short time when leaving a campground.
So, $3,100 bucks later, I have $1,200 worth of new parts, with the remainder in labor. Two broken bolts on a manifold caused the extra labor. The dealer said that 80% of the time they have at least one bolt that breaks.
Purportedly, the cause is poor quality diesel that leads to a carbon build up, and blocking of the EGR valve binding. Discount fuel sources like Kroger’s/Freddy’s, etc and biodiesel were mentioned as places to avoid. Chevron was the product they said was their personal choice. For the first 30 to 40 thousand miles on my truck, I used Space Age fuel, but switched to Chevron when the SA station started selling Bio only.
I don’t know if other brand diesels are affected by fuel quality, but you might consider researching what truck manufacturers recommend to avoid a similar issue.
