P261F . , P240F - seems like P261F was first and now other systems are

Hello, the diagnostic trouble codes found on your Sprinter will give clues for a technician to troubleshoot and determine what's going on. The P261F code typically refers to cooling system concerns. The most common cause I've read of is a water pump concern, as well as possible corrosion from coolant in the vacuum tank. But this is a guess and testing by a professional should be carried out. P240F seems to be related to the Diesel particulate filter (DPF) or EGR cooling system. It's hard to know - again - without performing hands on testing to see what is going on. This is specialized stuff - so you'll want to find an experienced Sprinter technician near you. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Those codes can definitely point to some specific issues. The P261F code usually refers to a problem with the auxiliary water pump, while P240F can relate to issues with the EVAP system. When the auxiliary water pump is not working properly, it can cause your engine to overheat and potentially affect other systems, which might be why you’re seeing multiple codes now. The EVAP system issue could be a separate problem or related due to the strain on the vehicle from the initial issue. To get things sorted, you’ll want to start by addressing the P261F code. Checking the auxiliary water pump for any signs of failure or damage would be a good first step. If it's faulty, replacing it should help clear that code. Once that’s resolved, you can see if the P240F code still persists. If it does, then checking for any leaks or issues in the EVAP system will be necessary. As DaveJM said, it’s a good idea to get a professional to take a look, especially with a vehicle like a Sprinter, where systems are tightly integrated. They can run a thorough diagnostic and make sure everything gets fixed up properly.
