Jun 28, 2. When's the last time you pulled your dpf filters and had them professionally cleaned?

We normally have to pulse filters about every k, k for high idle applications. ExOTRJun 28, Intothesunset Thanks this. Jun 28, 3.

Filters have been pulled today and cleaned,all of the DOC pressure temperatures etc look normal according to a manual. Jun 28, 4. Jun 28, 5. What do you mean by bad quality DEF? Jun 28, 6. Jun 28, 7. Jun 28, 8. Jun 28, 9.The Ford 6.

While issues are expected from a clean-late engine. Especially one as advanced as the 6. Ford 6. The weak link in the Honeywell Dual Boost turbo during early production years seems to be the ceramic ball bearings.

Reliability concerns with the turbocharger were eradicated with the introduction of steel ball bearings. A turbo failure on these model years is hard to miss, as an obnoxiously loud screeching sound.

It is exhibited in addition to smoke being emitted out of the tailpipe due to burning engine oil. Early build model year pickups equipped with the 6. These were defective from the factory. Persistent problems in later model years has not been identified with any considerable frequency.

But that is not to say that radiators from later model years have not developed leaks over time. NOx sensor failures were extremely common on model year engines. Under certain conditions, engine power is reduced as a result of a faulty NOx sensor.

In which technicians checked and replaced faulty sensors in addition to uploading an upgraded emission control strategy for the SCR system. The Customer Satisfaction Program expired April 30th, Considerable controversy resulted as emergency vehicles were left stranded, prompting Ford recall 13S10 to replace the faulty sensor s.

Similar instances have been reported in pickup models, although these incidents appear much more isolated and have not contributed to widespread concern. There have been multiple reports that the glow plug tip on early production 6. The problem seems to be isolated to certain chassis cab models. Had Ford detected a problem with the factory glow plugs, a recall or service bulletin would have been likely in order to reduce the onset of expensive warranty claims. Satisfaction and peace of mind is what you experience when buying from Roadmaster.

One of these new developments for these motors was a new engine management computer — called a DME in BMW terminology — as well as a development of their variable valve timing tech. The sensor, mounted on the exhaust system before the catalytic converter, measures the level of nitrogen oxide i. Traditional combustion engines without this technology would simply have the same fuel mixture for all conditions, making them compromised and less efficient than they could be.

The double-edged sword of these new innovations is that whilst these systems mean that the N43 and N53 series engines produce more power and burn less fuel than the outgoing units, these NOx sensors have proved prone to failure. Here are the key symptoms of NOx sensor failure for these engines. Without information from the sensor, the engine management software cannot accurately work out how the engine is running in terms of the fuel mixture and air-to-fuel ratio. If you find that your fuel economy drops during regular driving, this could be a tell-tale sign of a faulty sensor.

One of the tell-tale signs of a faulty nitrogen oxide sensor in an N43 or N53 powerplant is an unstable engine speed at turnover. The fuel injectors have to keep a certain flow of fuel into the combustion chambers at idle, a task that is electronically managed by the DME. But with a faulty sensor, surging and starving of the fuel can result in an uneven idle instead of ticking over at around rpm.

Although the NOx sensor itself is not mounted in the engine bay, component failure will likely result in an engine warning light. This, of course, is not the most specific indicator of a NOx sensor giving way, but it paints a clearer picture if your car is also experiencing the previously mentioned warning signs. Below you will find a list of BMW cars, which are using our listed sensorsto make sure we have correct part for your car we will need to get a picture of your old part or at least part number bmw or either continental, siemens vdo.

Similar to EGR problemsthe DPF can become clogged up from city driving where the car does not get up to temperature.

The whole reason the Diesel Particulate Filter came along was to clean up the diesel car image Euro 5 Emissions, Emissions from diesel cars are a big concern worldwide and thanks to the DPF technology, diesel cars are much cleaner. DPF regenerationrepairs and new replacements are seriously expensive and can lead to some vehicles becoming scrapped. After the regenerating of the DPF, it can now restart the cycle of collecting harmful exhaust gases again.

There are 3 different types of DPF regeneration, which are active, passive and forced. Active reads the back pressure of the exhaust or soot load of the filter to determine when to begin the regeneration.

Once initiated, the timing of the fuel injection will alter that will result in the exhaust temperature increasing to burn the soot particles.

Passive will take place once the exhaust reaches optimum temperatures where the regeneration will automatically begin. The exhaust will reach these temperatures will occur mostly on prolonged highway driving. Manufacturers that use a passive form of regeneration typically install a oxidizing catalytic converter near the engine to increase the temperature.

The diesel car will enter limp mode and will require a car diagnostic tool to force the regeneration.

How long until a DPF will fail is hard to tell because some manufacturers have had to replace some in the first 3 years and some never. The most common reasons for DPF failures are:. However, sometimes these warning lights can be false alarms and you should try clearing the fault using an OBD2 diagnostic tool. If the warning light continue to display, you will notice the following symptoms:. The cost of cleaning or replacing your DPF sounds scary but you can forget this following some simple driving habits.

With that in mind, here are 5 ways to fix a blocked DPF:. If you are currently in limp home modedriving at high RPM step 2 will be your best chance of getting out of limp mode.

Once you have normal power, go for a long fast drive on high quality fuel. If the issue remains the next day, get your error codes read by a diagnostic tool. It is true, without a DPF, you will have no issues and in fact, your performance will increase with a remap or tuning of the ECU. However, the DPF removal may be illegal is your country and it will cause more environmental damage. Although the latter will not be your biggest concern.

The cost of cleaning or replacing your DPF can be expensive. However, they did not bet on having issues such as DPF failure on relatively new cars costing thousands. It is not the Diesel Particulate Filters fault the majority of the time.

Its your driving habits as the car owner and lack of knowledge with modern diesel cars. If you are driving a few miles each day, your DPF will eventually give up and repair bills will start piling up. A gasoline engine is perfect for short journeys and equally as efficient on fuel.

If you know that you have a blocked DPF, you could be in limp mode also. Limp mode is more likely causing the issues with the automatic gearbox changes.This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.

This code is set either because there is too much NOx in the exhaust system or the NOx sensor itself has failed. Too much NOx in the exhaust stream can be a result of many factors:.

The Check Engine Light will be on. Aside from this, there will typically not be any other symptoms. The first step is to connect a scan tool and verify the code.

If the code is present, the freeze frame data should be recorded, the code should be cleared and the vehicle should be taken on a test drive to see if the code returns. Often times this code can be set under certain extreme driving conditions. One example is towing a large load up an extended grade. If the code returns during the test drive or before, it will be necessary to perform the following tests:. Check the other sensors in the exhaust for correct operation with a scan tool e.

If this is the only code set, it is easy to dismiss any other data that seems incorrect. If the scan tool data shows multiple sensors out of spec, time should be spent considering what data is the source of the problem and what data is a result of the actual problem.

The DOC system has a warm up state, a maximum efficiency state and an extreme conditions state. Failing to consider the state of the DOC system at the time of the code being set will almost definitely result in a misdiagnosis. Knowing what each stage does and how it will affect the scan tool data is paramount to the correct diagnosis of this system. Each stage has a variety of processes that need to be completed during specific conditions to sustain operation at peak efficiency.

If the on board diagnostics performed by the computer fail, a corresponding code will result with a Check Engine Light illuminated. This code is set because it failed one of those ECM tests. The only real problem with this code is the emissions that affect the environment, if this code is a hard code and the NOx sensor is in total failure.

Some manufacturers choose to program a low power output mode into the ECM as an incentive for the owner to have this system repaired. It is common for this code and others in the DOC system to be set because of extreme conditions.

Once those conditions are no longer present, this code will no longer apply. Clearing the code and test driving to see if the code returns it may have been set under extreme conditions that are not longer present. Repairing any intake manifold leaks. Replacing the ECM. The DOC systems are exclusively used on diesel powered vehicles.

The manufacturers experimented with three different designs but eventually the consensus was the DEF system was the best. Other systems reduced power output or were more expensive to maintain. The only drawback of the DEF system is it requires the owner to add DEF fluid to a tank, not unlike the washer fluid reservoir. If DEF should run outthis emissions system will not operate and a check engine light will turn on.

A Lambda sensor may become damaged, sluggish or completely fail.

If any of these symptoms occur, a vehicle owner should address them soon, as waiting may cause further complications. According to Fueleconomy. An early warning signal of Lambda sensor failure in the form of an uneven idle can be noticed by a driver who feels the vehicle wanting to surge ahead when at a red light or stop sign. Or, conversely, when it is time to go, the driver feels the vehicle hesitating after the accelerator is applied. According to CatalyticConverter. In this case, the ceramic monolith can melt, and the vehicle's exhaust path could become blocked.

Depending on the extent of the damage, engine power may become significantly reduced. The "Check Engine" light may come on. A vehicle owner will have to have a reputable technician check the code.

A cold engine with a faulty Lambda sensor that has unburned oxygen in the catalytic converter may emit a "rotten egg" smell. The vehicle's computer will make the correction according to the signal that the Lambda sensor sent, decreasing the amount of fuel in the ratio, causing the spark plugs to misfire. A malfunctioning Lambda Sensor may cause a vehicle's exhaust to be too rich in unacceptable emissions unused hydrocarbons and carbon monoxide.

In this case, unfortunately, the sensor has to be replaced. No cases, when the error messages regarding NOx sensor are recorder without correct reason, have been observed, just few exceptions:.

Such case requires specific check-up of NOx sensor — some specific abnormalities can exist also without recording in the MSD80 error message memory. Please, proceed encoding of new NOx sensor after replacement as described here. Heat up the engine to work temperature. After few minutes of driving temperature should be Note: conditions engine and exhaust system temperature readings mentioned above are compulsory requirements for normal operation of NOx sensor.

During two minutes after necessary exhaust system temperature and driving speed has been reached, the content of NOx has to become different from 0 ppm bar No. If the bar No. Using such sensor with increased Offset value will lead to problems in near future the error message 30E9 regarding aging of NOx catalytic converter can be recorded prematurely; as soon as MSD80 will confirm the increased value, it will switch off the Stratified charge and Homogeneous lean mode, and the engine will encounter all problems, which are described here.

If the parameters named before are within the normal range, the Lambda measured by sensor have to be evaluated bar No. This Lambda has to correspond with average value of Lambda measured by both wide-band probes of engine exception: overrun mode, see below. If this defect is not rocognized in time, more problems will appear — error messages regarding NOx catalytic converter, misfire, incorrect adaptations. Lambda evaluation in the overrun mode. Drive your car at After few seconds Lambda value bar No.

If the value is lowered or is reached after a long time more than 5 secondsthe sensor is clogged and should be replaced. Skip to content. How to evaluate the performance of NOx sensor? Detailed info: read here.
