These are the 3 errors that popped up: 255C00: Exhaust gas recirculation actuator, position control: valve too far open / negative deviation. 2B5700: Coolant temperature sensor before EGR cooler, signal: open or short circuit to positive. 244C00: Boost pressure control, control error: boost presure too low / positive deviation.

BMW, Nissan and Ford are among several manufacturers to have issued safety recalls in recent weeks. BMW is recalling 30,812 MINI Clubman, Convertible, 3-door and 5-door Hatch models as well as 4923 BMW 2 Series Active Tourer models fitted with diesel engines due to the possibility of a EGR coolant leak.

What to look for when buying a BMW X3 2010 - 2018, covering common problems to check for and overall vehicle reliability. There have been three recalls for leaking EGR coolers and apply to

Failure Date: 03/06/2019. Tl the contact owns a 2012 BMW X5. While driving approximately 45 mph, the check engine and egr system indicators illuminated. The vehicle was taken to BMW of kansas city (816-895-6228, located at 1200 w 104th st, kansas city, mo 64114) where it was stated that there was no recall. Monitoring detects the fault as follows: 1. The fault is detected if the exhaust gas pressure exceeds a limit value. The limit value is calculated from a characteristic map dependent on the engine speed and fuel injection rate. 2. The fault is detected if the exhaust gas pressure exceeds a limit value. The engine will run in default mode and if the prob goes then it could be the maf. If the egr valve failed you would get an orange light on the dash. If you don't then the egr valve is working fine. There is a boost sensor on the side of the manifold, this can go faulty. That "duck noise" is typical for a failed EGR vacuum solenoid like you already figured out. If you don't have diagnostics check the engine coolant temp on cluster hidden menu. It should be near 90 C. Low running temps can make consumption worse and eventually causes problems with DPF. Hey guys, Does anyone one know why my car ( 07 BMW X5 E70 3
Step 2: Remove the engine cover. In order to gain access to the EGR tube, you'll have to remove the engine cover. There are usually three or four bolts that secure the engine cover to the top of the engine. Using a ratchet extension and the correct sized socket, remove the bolts and then remove the engine cover.

When a cold engine is started, the secondary air pump will run for a calculated amount of time. The check valve is the most common part to fail. On early X3 models, a flow meter is used on the inlet of the pump to confirm pump operation. In this tech article I will show you how to test the secondary air system valve on 6-cylinder M54 engine.
My dad's X3 28d had originally passed the first recall, as it was low mileage, and then developed the leak later. We were refilling the coolant every 1-2 months. I had a bit of a fight with the BMW dealer, but they eventually re-did the check, and found it leaking. The dealer replaced the EGR cooler and intake manifold on the recall. How to contact the manufacturer: Owners may contact BMW customer service at 800-525-7417. NHTSA campaign number: 21V907000. Check to see whether your vehicle has an open recall: NHTSA’s website EGR Valve Stuck Open. An open EGR valve allows exhaust gases getting into the engine but at the wrong time. Common warning signs to look for are: Rough idling. The engine does not kick off. Stalling and hesitation of the engine. The check engine light coming on. Increased emission is a warning sign. Luckily, still no problems in driving (or not that I can notice). But I had a similar code on my E46 (M47 engine) along with few others and replacing the EGR pressure converter (#11747796634) resolved the problem. I was thinking of doing the same here on my tractor (also as a precaution, since these old valves do die) but I got lost in the process. VyK6.
