A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. It can also cause vehicle emissions to increase.
What are the symptoms of a clogged EGR cooler?
- White steam or smoke at the exhaust.
- Lowered coolant level with no leaks.
- External coolant leakage.
- Check engine light.
What does the BMW EGR cooler do?
The Exhaust Gas Recirculation (EGR) system on some BMW models features an integrated cooler for cooling exhaust gases that are recirculated back into the engine to reduce emissions. If the cooler suffers an internal leak, however, the glycol coolant can mix with diesel engine soot.
What is the BMW EGR recall?
The EGR cooler may leak internally, causing coolant to mix with diesel engine soot, which could result in smoldering particles and a melting intake manifold. Dealers will replace the EGR cooler and inspect the intake manifold, replacing it as necessary, free of charge.
Can EGR cooler cause turbo failure?
The results of this failure can damage a number of different EGR system components, including the VGT turbo. Most failures happen inside the EGR cooler, so it’s easy to miss until symptoms start to show up elsewhere. Don’t let a failing EGR cooler keep your diesel engine down!
What causes EGR coolers to fail?
How long does an EGR cooler last?
The average EGR cooler lasts about 80,000 miles or 128,7475km, though existing faults or damage from upstream issues can shorter its life. The tubes and EGR valve can also become clogged with carbon build-up over time.
How much does it cost to replace an EGR cooler?
For a replacement EGR cooler you could be looking at between $270 and $3700, which will vary from case to case. The higher end pricing usually applies to modified or high performance engines, so for a passenger car you are likely looking at the lower end of the spectrum.
How long does BMW EGR recall take?
Contact a BMW dealership to arrange for repairs. If you’ve had the recalled component repaired recently, it can take up to 3 weeks for the manufacturer to update their records. This information is provided by the vehicle manufacturer. If you think the information is wrong, contact the vehicle manufacturer’s dealership.
Can I replace my EGR valve myself?
It should be done by a professional Replacing the EGR valve is highly technical work for the average car owner and should usually be done by a trained auto mechanic to avoid any subsequent issues from occurring.
What is the latest BMW recall?
BMW Recalls 2022 I4 and 2022-2023 Ix over High Voltage Battery. BMW of North America, LLC (BMW) is recalling certain 2022-2023 iX xDrive50, iX M60, 2022 i4 eDrive40, and i4 M50 vehicles. The high voltage battery may have internal damage, resulting in an electrical short-circuit.
Does EGR valve affect turbo?
Engine performance issues: if the valve is stuck open the vehicle’s air-fuel ratio will be disrupted causing engine performance issues such as reduced power, poor acceleration and rough idle. It may also produce turbo boost pressure leaks, causing the turbo to work harder.
How do I test my EGR cooler?
The best way to check if you have a bad EGR cooler is to pull your EGR valve; the EGR valve is located on top of the engine next to the engine oil filter. If you pull that valve out, it should be full of a nice dry black charcoal carbon which is from the exhaust system.
Is it better to clean or replace EGR valve?
If there’s much dirt and build-up, it’s better to replace it with a new one. Once you’re done cleaning it, place it back in its original position.
Is EGR covered under warranty BMW?
BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks. Additionally, any repairs to address other stored EGR faults which require the replacement of a failed EGR valve are also covered under the terms of this component’s extended time and mileage coverage that is described in this bulletin.
How much does it cost to fix EGR valve?
The average cost of replacing the EGR valve in your vehicle is anywhere from $250 to $350 on average, depending on your vehicle’s year, make, and model as well as the type of system it has. The cost of parts will be somewhere around $190 to $270, while the cost of labor will be anywhere from $60 to $80.
Is BMW involved in the diesel scandal?
BMW later admitted to installing cheating emissions software in 11,400 “by mistake”. Government-funded research has found that BMW some diesel engines are emitting toxic fumes up to seven times the legal limit.
Can an EGR cooler be cleaned?
The best way to clean an EGR cooler is using ultrasonic cleaning technology offered by some radiator and other specialty repair shops around the country. It’s not that expensive, costing around $125, but not a service you’ll find in every town.
Can EGR cooler cause DPF problems?
If an EGR Cooler develops a leak, the coolant enters the engine exhaust through the EGR valve and is exhausted from the engine into the exhaust stream thus producing a different type of ash which will prematurely clog the diesel particulate filter.
How do I test my EGR cooler for leaks?
After placing the EGR cooler under water, shake and rotate the cooler for approximately 1 minute to ensure all air bubbles escape from the exhaust gas passage before testing. With the pressure set to 30 psi watch for air bubbles. Watch for at least 1 minute.
What does deleting EGR cooler do?
Installing an EGR delete kit reduces costs on repairs and fuel costs, as well as decreases soot deposits that an EGR valve produces. Disabling it prevents harmful contaminants from being reintroduced back into the engine, resulting in problems. When the engine’s performance increases, so does the fuel economy.
Is the EGR valve and EGR cooler the same?
The EGR valve is often a separate component installed in the EGR piping. In some designs, however, the valve can be integrated with various parts of the engine such as the exhaust manifold or EGR cooler.
Can EGR cooler leak coolant?
If the EGR cooling system develops a leak, water can escape into the recirculating exhaust gas, and pass through the engine, and disappear out the exhaust pipe, with virtually no symptoms, except of course for gradual coolant loss, the cause of which can be hard to diagnose. The loss is easy to identify.
When should you replace EGR cooler?
The EGR cooler is an integral part of your vehicle that ensures your engine runs efficiently, and that you’re doing your part and not releasing as much noxious exhaust. Typically you can expect to get about 80,000 miles out of the part, but defects and damage may cause its lifespan to be shortened.
How do you replace a EGR cooler?
- Locate the EGR Cooler. The EGR cooler is located on top of the passenger side valve cover.
- Drain the cooling systems. Place a drain pan below the radiator.
- Disconnect the PCM and EGR Cooler Fasteners.
- Unbolt the EGR Tube (Long Pipe)
