Mexican Diesel Fuel/Sulfur Effects Update

Although pickup trucks are not the same usage as an OTR ( 18 wheeler)many vehicles including PU's that utilize DEF have lots of problems even when using ULSD. The mfrs. were forced into installing these complicated systems without enough time to engineer a system that works properly. Large trucking companies that replace their fleets every 4 or 5 years have had to buy maybe 30% extra tractors to make up for those that are in the shop due to emission problems. Even when they fix a problem with a sensor or the software that problem may return in a few weeks. The dealers are stuck as they cannot modify the systems. They contact the engine mfr. who often will send out a prototype sensor or some different software. It is a nightmare. This summer I was driving longhaul. The truck was a 2015 Cascadia with a 600 HP Detroit D16. A real beast. It had about 35,000 miles when I began to have driveability problems. Dealer had it for 5 days. They finally got some new software and it seemed better. The next week I was in Kansas and a check engine light came on. In a few minutes I noticed it would not run over 60 mph. It was too windy to open the hood. I called Detroit and they remotely analyzed the problem. They can access the ECM. I limped to the nearest dealer where they forced 2 regens but the problem persisted. They called Detroit and the engineer said we needed a new " one box" This is the complete SCR system contained in one metal box. Includes a doser, the DPF and a bunch of other garbage. It is very heavy and quite large. Took 2 days to arrive. Has a retail price of just over $10,000 plus labour. Would you want to pay for this baby out of your own pocket? These things are far too complicated to let some hacker delete functions. Most of the shops that used to do EGR and DPF deletes have gone underground after one of them was fined mega bucks. I would certainly not alter any of my vehicles.( Maybe if ED offered a free warranty!)
