Engine and engine cooling, Other or unspecified, Dec 30, 2024
Driving down the highway and the DEF check engine light came on. It indicated to pull over and shut down immediately. I was on a highway that had long 7% grade hills with minimal places to pull over in arizona mou tain range. I was able to make it home after engine debated. Took to a freightliner dealer and paid 4400.00 to have DEF pump replaced. It turns out that was not the problem. I tried to go on another trip a month later and I hot a low DEF signal. I was told it was a DEF head. Freightliner XCS chassis our having lots of issues with DEF. The def is for emissions and should not shut the engine down or debate the performance for an emussion issue.
