🦐 Bmw X3 Egr Valve Problems

3 posts · Joined 2013. #12 · Feb 22, 2013 (Edited) I took my 35d in for the alternator recall. There was also a campaign on the EGR valve. BMW changed out the EGR valve, EGR cooler, SCR catalyst and mixer under goodwill warranty. The computers also had to be reprogrammed for the new components. Symptoms. There may be no symptoms of a P0404 DTC other than the MIL (malfunction indicator lamp) or check engine light. However, Exhaust Gas Recirculation systems are inherently problematic due to carbon buildup in the intake manifold, etc. This normal buildup can lodge in an EGR valve, holding it open when it should be closed. 2006 E83 X3 2.0d - Disable EGR Valve. As we all know, the engine in the X3 2.0d is very sensitive of getting block with nasty exhaust gasses/smudge from the EGR valve. I've seen many X3 where we had to remove de cylinder head to get it cleaned, just because it was so full of nastiness! The only way to keep you X3 clean is to disable the EGR valve. Recall no. 16V333000. BMW of North America, LLC (BMW) is recalling certain model year 2011-2017, X3 sDrive28i, X3 xDrive28i and X3 xDrive35i, vehicles manufactured July 2, 2010 to April 14, 2016 Hi my car is a 2011 bmw x5 40d. Just wondering if anyone has ever had egr issues with the following fault codes. 40D4, 4B82, 4C9E, 4C9F. The garage have fitted a brand new egr valve but it just keeps throwing up the same 4 fault codes every time. The garage is now saying they think it's because the car needs a software update. Thanks Intermittent loss of power, turbo lag untill 2000rpm. Hi guys, I have a problem with my 2016 X3 2.0xd, 8 speed Automatic Transmission, it goes like this: From a standstill, like a red light that turns green, if I floor it, barely anything happens for about 2 sec or so, until the RPM hits about 2000rpm, then it pulls like crazy. Put simply, the exhaust gas recirculation system (EGR) reduces NOx emissions in internal combustion engines. The system is made up of an EGR valve, a temperature sensor, and a control unit and it is connected to both the ECU and the intake/exhaust manifolds in the engine. The main purpose is to reduce these NOx (nitrous oxide) emissions and it The auxiliary exhaust gas recirculator flap or spring is broken. This part is mounted right on the exhaust manifold and then connects to a pipe that connects to the EGR cooler. It’s an easy replacement t job, remove the intake tubing on top of the engine and the plastic turbo pipe and then it is 4 bolts, 1 nut, 1 vacuum hose, 1 temp probe They have the same issues (check the E90POST\M47 M57 diesel forum); however the root cause is considerably different - on diesels the cause is EGR. The solution is also different due to the different head and intake design It's hard to say how many diesel owners are having problems, as BMW doesn't say and these forums are not representative at all. If the EGR valve fails to close, this may be caused by heavy deposits on the tappet or valve. The EGR may be damaged through overheating caused by incorrect control, high exhaust back pressure or non-opening blow-off valve. BTN Turbo supplies brand new replacement turbochargers, made by the original manufacturers to the highest quality standards. Gidday from Canada, In October 2020 I had my EGR and intake manifold replaced under Canadian BMW recall 2018-587. In June 2022 I had my EGR replaced again under recall 2021-711. I experienced consistent coolant loss after the 2nd repair, topping up with 250ml of coolant a couple of times and travelling 2200km before I got the limp engine code 1. Engine ping or knock. One of the first symptoms commonly associated with a bad or failing EGR temperature sensor is engine ping or knock. If the EGR temperature sensor malfunctions it will cause issue with the EGR system flow. This can cause cylinder temperatures to rise, which can cause engine ping or knock. A clogged or malfunctioning EGR valve can disrupt the vehicle’s air-fuel ratio, which can cause engine performance issues such as a reduction in power and fuel efficiency. The vehicle may also stall or hesitate while accelerating. 2. Rough Idle. One of the most common symptoms of a problem with the vehicle’s EGR valve is a rough idle. The EGR valve is normally closed. There is no EGR flow when the engine is cold, at idle, or during hard acceleration. The EGR flow is at its peak during steady cruising under moderate load. In some cars, the EGR valve is operated by a vacuum actuator, as in the first diagram below. Modern cars have an electric EGR valve with a step motor. In the case of the P042F, the valve appears (to the PCM) to be stuck in the closed position. The designation A applies to a particular position or stage of the step-down EGR valve control system, which is explained below. The EGR system is responsible for allowing the engine to consume a portion of the unburned fuel from the exhaust system. .
