Low temperature EGR cooler error..help needed

Hi,
I have an error i am struggling to resolve.
Coolant temperature sensor upstream of low temperature EGR cooler- error is triggered when a difference between the coolant sensor and egr low temperature sensor is seen.
— replaced egr coolant temp sensor x 2
— replaced main coolant temp
— at temp main coolant temp is reading 85 degrees C and EGR low temp sensor is reading 30.
— removed EGR temp sensor and cable in placed in cup of hot water. temp shot up to 70 degrees C.(this would prove operation of sensor is fine.
-When car is up to temp. EGR cooler is very hot to touch. coolant hoses hot to touch. however hose from cooler down to temp sensor is cool.
-My problem would appear to be that the sensor is reading what it is seeing and the coolant is not hot at that point. never gets above 30 degrees C.
From the coolant system flow diagram it would appear the coolant from the low temperature rad side flows past EGR temp sensor, up the hose(see pic attached) into egr cooler, cools the gas then flows into engine block.
I am curious what the operating temp of the low temp side should be??
The error happens on a cold engine also almost instantly.
I was thinking a blocked egr cooler, or faulty changeover valve or coolant pump.
But if the flow is going past the temp sensor before it goes into EGR cooler, something further back on the coolant line could be blocked??
Any help or ideas or how to test would be welcome my knowledge of this system is very little

Устранение ошибки P0138 BMW X5 F15

Ошибка Р0138 на БМВ Х5 F15 – это явление, с которым сталкиваются многие автомобилисты. Она указывает на наличие повышенного напряжение в цепи второго лямбда-зонда, что означает недостаточную концентрацию кислорода в выхлопах. При возникновении кода 0138 водители обращают внимание на «плавающие» обороты мотора и активацию индикатора CHECK ENGINE.

Ошибка P0138 на BMW X5 F15 возникает, если:

  • возникли неполадки в проводке кислородного датчика;
  • вышел из строя второй лямбда-зонд;
  • появилась поломка в выхлопной системе (например, код Р0138, свидетельствующий о высоком напряжении кислородного датчика, может возникнуть при разрушении нейтрализатора, расположенного перед ним; это достаточно серьёзная поломка, которая может обернуться выходом из строя цилиндров двигателя).

Sounds like you have a vacuum leak, check the rubber hose by the oil cap. It might be torn.

That will address the a few codes.

Also check/the EGR flap actuators, and the EGR vacuum lines� those also could be leaking or cracked.

As for the dpf, after doing all of those, perform a force regen and drive an hour on the free way at 70 mph.

That should clear up the dpf� if the dpf is real bad, then you might need a dpf service done.

mrrsharma@yahoo.com is right, most likely a vacuum leak. Have you had the EGR recall work performed yet? It’s also possible that your intake plenum is compromised due to the EGR/coolant issue.

So just to clarify, both the dealer and an inspection mechanic both showed only 2BB100 code show up. The other three codes only showed up at one independant shop I went to (which was what I posted above). Dealer recommend changing DPF filter and also indicated there was some oil leak and recommended gasket head cover replacement, which I am not sure if needed at this point.

I did buy the DPF part and looking to replace the DPF (all in all costing $2500 including labor at a local mechanic), but just have an lingering fear of the other three codes which appeared at another shop. I do hear some hissing sound that comes right at 2000rpm until about 3000 rpm, not sure if is turbo noise, but I thought turbos still have lingering spool sound when I let go of gas and since I don’t hear that, it does give me a bit of unease. I will have the mechanic check out all the hoses as you guys have recommended.

Similar issues. I am having the DPF cleaned first. They do this to trucks all the time, rather than pay to replace. Thee is a SB for cleaning it as well from BMW.

UPDATE : The car is still be in the mechanic shop for 6 weeks now. Mechanic doesn’t believe anything wrong with sensors.. (he hasn’t replaced any) and claims he has checked all pipes for leakage but hasn’t found any. (Although I am not certain he was thorough) He recommended replacing DPF as the solution which we did (cost me $3000) and I believe he cleared the codes and I was instructed to drive it to see if any codes will reappear. And it did. In fact, same set of codes plus some more (below) came back and CEL is on solid. Took it back to the mechanic, he doesn’t have a clue but to blame it on the newly replaced DPF which he claims is not OEM, thus could be the culprit, which I don’t believe is the issue since the codes are the same prior to replacing it. The part is brand new from WL-parts.com, a reputable company and the specs are exactly correct.

Current Codes :
290B00 — Air system, air to EGR mass flow plausibility; measured air mass too low compared to calculated air mass
290900: Air system, air to EGR mass flow plausibility: measured air mass too high compared to calculated air mass
2C2200 : Coolant temperature sensor in front of EGR cooler, plausibility: coolant temperature in front of EGR cooler to coolant temperature not plausible.
28DE00: Exhaust pressure sensor in front of the turbine, plausibility: exhaust gas pressure in front of the turbine is dynamically implausible
282900: NOx storage catalyst, plausibility: NOx regeneration efficiency too low
2BB100: Particle filter system, plausibility with particle sensors. Particle filter efficiency too low.
D35744: Message error (data drive train2, ID: DT_PT_2) — timeout
D358F8: Signal error (status distribution longitudinal torque front axle rear axle, ID: ST_REPAT_XTRQ_FTAX_BAX) — Invalid
805268: Transfer pump, control: implausible

Mechanic doesn’t seem to have a clue and tries to ignore the symptom that I am alerting him about — that there is a shrieking noise upon light acceleration from 1800RPM to 2200RPM. Some of you have indicated below advice, which I’ve forwarded to the mechanic.

At this point I can’t even get the car to be registered due to the fact that it can’t pass the smog test. The mechanic doesn’t seem to have a clue at this point and Im just trying to help him out otherwise, will need to find a more competant mechanic. Highly appreciate for those who are knowledgeable in with this situation to offer any insight.

Sorry to hear. The diesels can be a b*tch. And I only really have guidance on a few codes. One being probably one of the least important ones on your list. That being the «805268: Transfer pump, control: implausible.» Requires replacement of the DEF transfer pump. Dealership wanted $2800. Part is ~$450. I replaced it myself in ~3 hours. Been fine since. But that won’t affect any of your other codes. we drove with that code for ~12mo. It doesn’t set the CEL and only means you have to refill at the active tank fill as the passive stays full because the pump isn’t transferring DE fluid.

The coolant temp sensor code you have I am dealing with now. I need to replace the crossover valve according to BMW. They wanted $1400 to do that. I am doing it myself as the part is $275.

Your other codes are much more problematic and having spent money on a new DPF would certainly be rather frustrating. I’ve found that independent shops have almost no clue how to handle the diesels and their troubleshooting. Good luck, wish I could be more help. Could be so many things, or combined things. A turbo could have sh*t the bed.

X5 35d CEL light help!

290900 Air mass system: Measured air mass too high
290B00 Air mass system: measured air mass too low
2BB100 Diesel particulate filter: efficiency too low
2C2200 Coolant temperature sensor upstream of low temperature EGR cooler, coolant temperature, signals: implausible with each other.

My last 1000 miles, I did not see regen occur.
I took it to BMW dealer and they say I need to change my DPF.

Is this a faulty thermostat or DPF issue? Any other insight on probable cause? your insight would be greatly appreciated..

What request did you make of this dealer? If you asked them what was wrong then you got what you deserved. The problems are all over the place.

At whatever dealer you use, order work like this; Customer States: No noted DPF regeneration for 1000 miles. Diverse DTCs. Diagnose, estimate and cure on acceptance of the estimate.. Do not tell them anything else. Do not tell them how to do their job. Do not lead the ‘witness’.

You will PAY for hookup of the computer. You will PAY for the troubleshooting Service Plans. You MAY pay for the repairs if you accept the estimate. You will benefit from your state’s consumer protection laws.

I would at least give them a second chance using the work order as above. Otherwise get a second opinion. Don’t ask the shop to tell you what’s wrong so that you can have someone else do the work and get the profit. DPF are robust and not likely to need replacement. Better to force a regeneration.

290900 Air system, air to EGR mass flow, plausibility: Measured air volume compared with calculated air volume too high d73n57a0 Digital Diesel Electronics View

Fault Information

Fault Code Description
The measured air mass is too high compared with the calculated air mass.
Fault Code Conditions
General Conditions Monitoring runs continuously with active exhaust-gas recirculation control in the following time grid: 20 ms.
Control unit voltage: 9.5 V to 16 V.
Terminal Condition
Driving Conditions
Fault Time Condition
The fault is entered if it is present for longer than the following period (debounce time): 65540 ms
Service Plan
Check the following possible fault causes:
1. Air cleaner faulty.
Note: As of September 2011, air filter elements with increased tolerances were installed for N57D30O1 and N57D30T1, this can make the measured air mass appear too high, which leads to this fault. The faulty air filter elements have a thick grey fleece. These air filter elements must be replaced by a new filter element (thin white fleece).
2. Leaking bypass pipe of EGR cooler (pipe could be broken).
3. Exhaust gas recirculation cooler clogged.
4. Charge-air temperature sensor faulty (displays values that are too high, mostly without fault entry).
5. Exhaust gas pressure sensor before turbine faulty (in conjunction with the fault codes 27B900 and/or 4C83 and/or 28DE00 and/or 4990).
6. Charge pressure sensor faulty.
7. Leaks in the air mass system:
After the compressor (in conjunction with faults 241200 or 4674 and/or 241300 or 4679).
The fault can also occur in combination with charging pressure control deviations. Such combinations are a sign that leaks in the air mass system after the compressor are the cause.
Oil patches are signs of leaks.
Check whether sealing rings on charge air hoses are rolled back or missing!
8. Exhaust-gas recirculation valve jams in closed position (in conjunction with the faults 272E00 or 4C9E and/or 255B00 or 40D4) or does not close correctly.
Fault Impact
The fault can cause high fuel consumption and jerking.
Warnings
Warning Lights None

Fault Information

Fault Code Description
The fault is detected if the difference between the measured and the calculated air mass is too great.
The air mass measured is too low compared to the air mass calculated.
Fault Code Conditions
General Conditions Monitoring runs continuously with active exhaust-gas recirculation control in the following time grid: 20 ms.
Control unit voltage: 9.5 V to 16 V.
Terminal Condition
Driving Conditions
Fault Time Condition
The fault is entered if it is present for longer than the following period (debounce time): 65540 ms
Service Plan
Check the following possible fault causes:
1. Leak in the air mass system before the compressor (air cleaner, intake silencer, air pipes).
2. Exhaust-gas recirculation valve jams open (in conjunction with faults relating to the exhaust-gas recirculation valve).
3. Exhaust gas pressure sensor before the turbine faulty (in conjunction with faults on the exhaust gas pressure sensor)
4. Charge pressure sensor faulty.
5. Charge-air temperature sensor displays wrong values (most of the times without fault entry).
6. Check intake ports and intake valves for sooting.
Fault Impact
None
Warnings
Warning Lights None
Control Center Messages
Service Notes
The fault can occur when the exhaust turbocharger is mechanically damaged (compressor broken). The jammed compressor causes a high flow resistance which leads to a strong vacuum in the intake area after the compressor. This causes the measured air mass being too low.
Usually, this fault occurs in conjunction with a charging pressure control deviation.
If leaks were found in the air mass system, the following service function must be carried out: Delete adaptations, air mass system.
If the exhaust gas pressure sensor upstream of the turbine is being renewed, the following service function must be carried out: Delete adaptations, exhaust emission system.
If the exhaust-gas recirculation valve is being renewed, the following service function must be carried out: Delete adaptations, air mass system.
