Hey guys,

Getting DPF fail errors, checked my temp from hidden menu and its around 90 so I guess the thermostat is still good.

Carly says error is cylinder 1 glow plug and plausible swirl flap.

I'll replace all 6 glow plugs, but do you think the controller should be replaced as well as this part usually fails too?

If I delete the swirl, no need to tune for this delete right?

Also, I rang BMW and got quoted part numbers 12237786869 for glow plug and 12217801201 for glow plug control unit. But these parts do not coincide to whats in realoem, the compatibility in some websites like FCP, or even the compatibility checkers in ebay that the sellers have.

The car model is 2010 e90 330d lci, 180kw, with the n57 motor. Any advice guys? Thanks.

bump? - after 4 minutes?


The fault codes would be helpful for diagnosis.

Glow plugs on the high pressure common rail N57 diesel engines are not activated until <10C coolant temperature. If the vehicle is not misfiring at cold start then it should be ok. Generally glow plugs will not be utilised in Australia so even if all six glow plugs and the pre-heater display fault codes it will not detract from engine operation or performance.

The life expectancy of the DPF is ~250,000km. As the vehicle has completed less than half that distance the DPF should still be in good condition. Also no mention is made of trip duration etc. to determine if the regen mode is being activated or if "forced regen" has been implemented.

Plausible swirl flap can be an error attributed to when the flaps have been removed and the electrical control unit gives feedback to the DDE.

These are the correct part numbers for the components. Best to provide the last seven of the VIN to isolate the correct match:

12230035934 - glow plug
12218591724 - pre heater

haha, yeah 4 min bump, he bumped while the thread was on top. anyway,

Here's the fault from Carly, Ive only done Carly as I haven't set up inpa yet:

Fault Code: 004A6E
Fault Explanation: Glow plug cylinder 1, control
Fault Code: 0040E9
Fault Explanation: Abgasrueckfuehrsteller, position control
Fault Code: 004E0F
Fault Explanation: Swirl flap, plausibility
Fault Code: 004A6F
Fault Explanation: glow plug
Fault Code: 00480A
Fault Explanation: particulate filter system
Fault Code: 003FC0
Fault Explanation: Air flow sensor
Fault Code: 00481A
Fault Explanation: particulate filter system
Fault Code: 004D00
Fault Explanation: Exhaust back pressure sensor, signal
Fault Code: 004010
Fault Explanation: Exhaust back pressure sensor before particle
filter, signal

The story is, yesterday, wife told me that there was "Particle Filter" message, Possible to continue journey, Possible reduction in engine power.
So Last night I fired up carly and spat out the diagnostic above. Read the Soot level - 77, ash - 19. Requested a regen, after about 20 mins, it was down to soot-60 and ash 19. Was travelling 80kmh in 4th.
Tried to request a regen again but soot didn't come down, stayed at 60 afte driving for 20 mins, maybe because I didn't restart carly or the car?
The engine actually is misfiring at cold start, noticed this about 3 weeks ago, then it will smooth out after 5 mins in idle.
Not sure whether flaps have been removed, noy mentioned previously in log book, I wouldn't think so as it was all serviced by BMW.
Vin is NJ79343

I'll go out again tonight and force regen as the soot is up again to 77 after wife used it to go to work. Her travel is abt 23km one way with a lot of stop start and lots of 40-60km/h runs.
Ill clear the codes before requesting regen.

The part numbers you mentioned are the same from realoem where I initially thought was the correct part number. Don't know why the BMWDealership at Parramatta gave me 12237786869 for glow plug and 12217801201 for glow plug control unit. I actually confirmed with the parts guy what I had and what he was providing me.

If I buy from ebay, do I go with info from realoem?

Carly is fine for what you are doing. If you are still using WIN95 then INPA would be perfect. ISTA+ is the most current dealer level diagnostic software and can be really useful in running test plans in situations like this to isolate a problem.

A lot of those fault codes can be caused by a vacuum leak so have a good check for any loose connections, cracked hoses etc.

After a regen the soot level should return to a single digit and then quickly rise again. Upto about 100g the vehicle should operate without limp mode.
The wife's travel regime should easily initiate a DPF regen so it's just a matter of isolating the system malfunction.

At 42 RPM the glow plug controller shuts down so once the engine is started any misfire would not be attributed to the glow plug.

Use the RealOEM part numbers with confidence.

Hmmm weird thing happened last night when I was testing with carly, here are the events:

Started the car, drove for 15+ minutes around 80kph. I then checked the DPF numbers - Soot - 77.485199 Ash - 19.333153
Drove for 15+ mins, doing 80km/h on 4th. heres some of the log:

14.09.2018 00:40:26 Soot mass Ash mass Regeneration requested Engine speed
Motor: 51
14.09.2018 00:40:25 77.485199 19.333153 7.000000 2133.000000
14.09.2018 00:41:01 77.485199 19.333153 7.000000 2105.000000
14.09.2018 00:51:34 77.485199 19.333153 7.000000 2191.500000
14.09.2018 00:43:56 77.485199 19.333153 7.000000 2949.000000
14.09.2018 00:43:59 59.998386 19.333153 7.000000 2560.500000
14.09.2018 00:43:59 77.485199 19.333153 7.000000 2524.500000
14.09.2018 00:44:25 77.485199 19.333153 7.000000 1041.000000
14.09.2018 00:45:09 77.485199 19.333153 7.000000 678.500000

It's weird that the request for DPF regeneration did not register as I definitely requested.
Throughout the drive the numbers were consistent apart from the reading 59.99 where it blipped in that value when I tried to redline in 2nd.

After that drive, I scanned for faults:

Fault Code: 003FC0
Fault Explanation: Air flow sensor
Fault Code: 004A6F
Fault Explanation: glow plug
Fault Code: 00480A
Fault Explanation: particulate filter system
Fault Code: 00481A
Fault Explanation: particulate filter system
Fault Code: 004010
Fault Explanation: Exhaust back pressure sensor before particle
filter, signal
Fault Code: 004D00
Fault Explanation: Exhaust back pressure sensor, signal

So I was stumped, something wrong with carly? Decided to go for another run.
I stopped the car, turned off ignition and aux then locked it, waited 2 mins then started it again. cleared the fault then checked DPF numbers - Soot - 77.485199 Ash - 19.333153, drove again for 15+ mins, doing 80km/h on 4th. heres some of the log:


14.09.2018 00:50:12 Soot mass Ash mass Regeneration requested Engine speed
Motor: 51

14.09.2018 01:04:53 59.998386 19.333153 7.000000 684.000000
14.09.2018 01:04:54 59.998386 19.333153 7.000000 679.000000

As you can see, after abt 3 mins, the soot dropped down to 59.99 but it wasnt gradual, it was sudden, then stayed there.

After that drive, I scanned for faults:

Fault Code: 003FC0
Fault Explanation: Air flow sensor
Fault Code: 004A6F
Fault Explanation: glow plug
Fault Code: 00480A
Fault Explanation: particulate filter system

So yeah, not sure what to do/check from here.

Before requesting a DPF regen clear all fault codes.
For the request to be carried out all conditions must be met including at least 10 litres of fuel, temperature before cat of 240C, coolant temperature of at least 75C.

The optimum regeneration is achieved after 20 minutes at a constant speed of at least 60kph.

Also this website will give you some more information about the fault codes: http://bmwfault.codes

Yep, i cleared the fault codes before requesting on both runs.
Tank is 3/4 Full, didnt check temp before cat, coolant is at 91.

Just wierd that the reading of soot only had two values. 77.485199 and 59.998386. Is it safe to say that the DPF reading is not working properly?

Thanks for the link, I'll have a look at the codes, maybe time an indy got involved...

Yes the change in value suggests a sensor issue or perhaps a glitch with Carly.
As well as the obvious parameters I mentioned there are others required by the software interrogation by the DDE so unless everything is met the manual regen request won't happen.

This is where the ISTA+ diagnostic software is really beneficial as it will test the components. If you know someone nearby who has ISTA+ it would be helpful rather than paying a garage.

Unfortunately I don't know anyone who changes their own engine oil so highly unlikely that they would scan too haha.

I guess it's time to read up on ISTA+ and see if I can get it fired up on my laptop. Been putting it off as carly is just more convenient.Got the cable from https://www.bimmergeeks.net/product-...eeks-pro-cable. Any tutorial sites you can recommend? I haven't used any of the scanning tools before.

My mechanic(whom I set up his PC/printer/wifi for his shop) has G-Scan2, I'm sure I can nick it off him for half an hour.

Thanks Ken

Great that you have the cable.
I will put up ISTA and PM you a link to download and install with instructions.

The software is intuitive so not much of a learning curve.

OK Guys, just want to update and share my experience in the hopes of it might help someone out if they ever come across the same issues I had.

To recap:
DPF Issue light came on. Car is e90 330d lci 2010 built.
Tried carly to force regen but was bugging out and also there were some codes that carly could not clear(specifically 003FC0 - Air Flow Sensor) so the regen request wasnt taking place.
Soot Level was around 70 and I could feel the car was getting more sluggy everyday.

So Ken, whom by the way have been so helpful with my saga all the way, and I have taken it to private messaging to diagnose my issues.
Downloaded ISTA D as I have bought the K DCAN cable from bimmergeeks a couple of weeks back(as recommended by Ken before).

I couldn't get ISTA installed on my old dell E6230 running windows 7 sp1 without errors, but I will elaborate on that later.

After about a week of driving the car I could definitely feel major power loss. DPF fault camo on after 10 mins as usual. After about 20 mins, suddenly there was like air blowing through the hood with a funny distinct smell as i can smell through the cabin. I cannot see the air blowing through but just hear it, like letting air out of your tires sound when I step on the gas. Got the carly out and cleared codes, funnily enough the dpf light didn't come back on and I was successful at regen as i saw soot decreasing and the soot was being read properly thus time, got it down to 60 gms. I didnt continue longer as i just tried to head home because of the hissing sound. Msged Ken about the issue and he advised to get BMW or an indy to diagnose before anything expensive is damaged.

The Indy(euro specialist) experience.
After about 2 days, I was on my way to the indy to get it checked out, the car didn't have any hissing sound anymore, and the power loss was not as significant. Explained to the mechanic about issues so far and I left to go to work. Later he called me to tell me that he scanned it and there were no issues he could see with the car and just that the DPF was dirty. I asked him what caused it to be so dirty as maybe there's an underlying issue:
- said that maybe bad fuel, maybe fuel wasn't getting hot enough.
- Told him that these DPF were good for around 250k kms(as advised by Ken previously) and he said no way, these DPF will be lucky to hit 100K
- Said that he gets this all the time and that the solution is to take DPF out, clean it up and put it back in. Quoted me 700 to clean and 300 for labor.
-I asked will it come back? he said yes usually, then he'll just need to clean it out again and treat it like a maintenance thing
So at this point, I know this guy was having me on. So I said ok, I'll just pick the car up and decide what to do later. Charged me 160 for diagnosis and later when I picked up the car, he said that he tried to regen as much as he can before I came, but it still needs cleaning. He also advised not to force regen as he said this will melt the catalytic converter. I said ok, paid him then left. If anyone is interested who this mechanic is at Seven Hills, PM me so you can avoid this clown.

So when I got back home, I tried to force regen again. Carly this time was reading accurrate Soot levels - around 52gms. The regen wouldn't kick in as there were some faults that I couldn't clear. The car drove like it was before when I dropped it off to the indy, bit sluggish and no hissing sound. I have been messaging Ken and he has been giving me advise on how to resolve the issue. since 3FC0 error wouldnt allow DPF regen to occur, really need to get ISTA working to clear the codes.

Ken helped me out getting ISTA installed and I have been bugging him with my issues for more than a week with the car and software installation. Ken advised that the MAF could be faulty or needs cleaning. Try cleaning it first as they are expensive to buy. I bought CRC MAF Cleaner and cleared 003FC0 code and reset the Air Flow Adaptations as advised by Ken and he also told me the steps on how to do these things. I cleared the codes, reset adaptations but regen still wont kick in. I was on the side road and PM'ed Ken that this was where I was at and I mentioned that there was one error that i couldn't clear - 004A6F - DDE Control Unit. Almost instantly he replied, while I was on the road, when I needed prompt assistance. He said the error shoudln't cause the DPF not to regen. So I tried to request again through ISTA, and figured out my earlier mistake why it wouldn't regen. In the steps in ISTA to request regen, theres a message there that regen wont occur if there are faults not cleared. I didn't continue past that step and I thought that ISTA wont let me regen. so this time I just clicked next instead of backing out and was successful in requesting regen.

And after 2 weeks of grief, DPF was regenerating! I got my carly out to look at the levels and I got it down to 36 before it stopped. went back home and decided I would try again later. Went back out after 2 hours and requested regen, and I am so glad to tell you that DPF is now at 0gms, going up normally, Car got it's power back, and no faults at all when scanning again.

My ISTA Troubles:
So I was installing ISTA to diagnose the car and to delete codes, and reset adaptations as carly cannot do this. I was having issues launching the software. It wouldnt open and error was CLR20R3. Ken immediately advised that this is a .net related error and advised to cumulatively install the .net frameworks and try again. Did that and got it working. Tips to anyone having issues in Win7 sp1 ISTA install:
-Make sure that BMW Standard tools is installed before you install ISTA
-since windows 7 has .net framework 3.5 within it, download and install all the later versions - 4.0, 4.5, 4.51, 4.52, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, 4.7.2


TLDR: CAR DPF issues and ISTA install issues. Ken helped me out on two fronts and now car is purring again like a kitten.

Lastly, I would like to just say that Ken, Thank you very much for your help and for putting up with me and my issues. You helped and advised me heaps and I have avoided getting a large bill and now have a working tool to diagnose my car in the future, You are an asset to this community with your expert knowledge and willingness to help people out. Thank you.

Hi Everyone, this is my first post and looking to get my first BMW. The E90 seems to be the one in my budget and need some feedback on the usual question of which one of the petrol models should I consider (4 door models).

Regards
Chris
