The EGR valve in the Ford Transit Custom is prone to clogging with carbon deposits, which can lead to issues with the engine’s performance. When the valve becomes clogged, it fails to recirculate exhaust gases properly, affecting the overall functioning of the vehicle. Answer: The EGR monitor can not be replaced, in that it is not a smog component. Emission monitors are internal self-tests which the Engine Control Unit performs to ensure a vehicle is not polluting and is running efficiently. The entire process of self-testing various emission control systems is called a Drive Cycle. Stage 1 Remap. EGR Delete. DPF Delete. Adblue Delete. Speed limit removal. First of all, the most important aspect to any tuning is the pre map health check, on the Ford Transit Custom this includes the following. Visual inspection of the engine, fluid level checks. Full global scan of the car to check for any unknown issues or fault codes stored. I have a 2007 Ford Transit, having done only 80,000 miles. The Engine Management Light is permanently on. The main dealer has reset it and tells me the EGR valve wants replacing again. It remained off for approx 2 weeks and then lit up again. This is the 5th time it has needed replacing. This seems a common fault, and really frustating and Step 2: Test the EGR Position Sensor. Using your multimeter, measure the resistance across the EGR position sensor terminals. Compare the readings with the manufacturer’s specifications. If the readings are outside the recommended range, you may need to replace the sensor. Step 3: Inspect the EGR Valve. CASE 1: Engine vacuum was present after the engine was started and was idling. This test result indicates that the vacuum line is good and delivering the goods to the EGR Vacuum Regulator Solenoid. The next step is now to test the Power Circuit (12 Volt) of the EGR Valve Vacuum Regulator Solenoid, go to: TEST 5: Testing The EGR Vacuum Regulator FORD TRANSIT CUSTOM 2012-2015 2.2 TDCI EGR COOLER (Fits: Ford Transit Custom 2013) £22.00.

Common symptoms of this phenomenon include lumpy running when at idle, power loss and difficulty when faced with hills, as well as sometimes giving fluctuating readings of the temperature gauge. These issues can often by misdiagnosed as a blocked air intake, turbo fault or EGR valve malfunction, when in fact it’s a faulty thermostat.
