Two other sensors, the Charge Pressure Sensor and Air Intake Pressure sensor, will also cause the vehicle to go into limp mode if they are faulty. If this is broken your vehicle will probably go into limp mode. Turbo Actuator Electric Vacuum Control Valve or Air Sensors: The Turbo Actuator Electric Vacuum Control Valve is a small solenoid valve that regulates boost pressure. Can replace with a durable aluminum unit to fix the faulty factory part. Turbo Resonator : Common failure part on these vehicles. Pre 2007 turbochargers can have their actuators adjusted. Turbo Actuator : We don’t offer this item separately, but often times the turbo isn’t working correctly because the electronic actuator is broken. See our article about this problem here.Ĭauses of Limp Mode on Pre 2007 Sprinters: Check your fuse box for a blown 15A fuse. If you are getting a bunch of air sensor codes that are impossible to clear, you might have blown the fuse that sends power to these sensors. Trying to repair the hose is unlikely as oil vapors will break down any adhesive used to make a repair.

These hoses expand when pressurized, so a crack or split may not be noticeable if the hose isn’t under pressure. Check all sides of all curved hoses by squeezing the hose vigorously. The most common leak on the V6 engine is the green o-ring in the metal pipe that is attached to the turbocharger.Īny curved hose is also a candidate for developing a split. Replace the intercooler o-ring seals or refresh the hoses themselves to fix any leak you find. Any buildup of black “gunk” near a fitting is an indication it is leaking. The most often leak occurs at the fittings where hoses attach to hard pipes or the intercooler. A leaking hose will cause limp mode as the vehicle will be unable to maintain specified boost pressure. Sprinter Intercooler hoses are prone to leaks. Air filters are cheap and, on Sprinters, very easy to replace. A clogged air filter can chose the engine of air and result in inadequate turbocharger boost pressure.

The easiest solutions are often the best solutions, so, always check your air filter first before digging into other problems. Limp home mode is more often caused by things other than the turbocharger, things that are vastly less expensive than replacing the turbocharger itself. We most often hear of “limp home mode” being diagnosed as a faulty turbocharger, and, accordingly dealerships and service centers replace the turbo for thousands of dollars.Unfortunately, this could end up being a monumental waste of money.

Limp home mode has little to no turbocharger pressure and vastly reduced fueling, and the engine is only making a fraction of rated power. Your Sprinter’s ECU senses something malfunctioning in the turbocharger system–either reading too much boost, too little boost, etc.–and decides puts the van into low power or “limp home mode”.

Bringing the end user an exceptional level of driving experience.“Limp Mode” or “Limp Home Mode” is a condition that can affect turbocharged diesel vehicles. Our development procedures focused heavily on drivability with reliability. With over 16 years of experience tuning small diesel engines in the USA we have been able to achieve exceptional performance for the VS30 3.0L Sprinter. We first started tuning 3.0L Engines in 2009. KERMA brings years of experience of tuning the 3.0L diesel engines.
