Interesting! You've got slightly less ash than I do, but about 16k more miles.

I bought my X5D back in July w/ 102.5k. My dealer drove it from Boston to Minneapolis for me, so by the time it got here, it was at about 105k. Wish I'd started tracking sooner, so I could see how my driving habits have added to the ass value.

 

My x5 was daily highway driven (~80+ miles minimum) by the first owner till 102k which is when i bought it. I do my fair share of highway use weekly or at least one long drive per month.
The 150k miles DPF life is just a value set by BMW is what i read. I guess its possible to reset it by saying you put a new one in. Dont worry about the end of life until you get the DPF clogged light.
I read around that thats way into the 200k ranges or more.

FredoinSF> Any X5 owner should have carly and periodically monitor the vehicle like most of us do. One important thing you can catch before it becomes a problem is the thermostat failing which causes the regeneration to not happen which causes soot buildup which causes DPF clogging and MPG gets hit.
Get carly.

I have the Carly adapter and app. Used it on the 650 to register the battery a year or so ago, made some function changes for lights, etc...

I've never hooked it the X5 cuz no signs of trouble. I'm well aware of the thermostat early fail based on other members' posts, and you're probably correct that I should test the coolant temp sooner rather than later given the car's mileage (63 or 64k). My understanding is that it manifests itself via fuel mileage drop which I have not experienced, so I have not monitored operating temp.

That being said, I'm interested in these ash numbers so I'll have to find the Carly adapter. That will be an interesting project in itself given the state of my garage which is still in chaos after we sold what had been our primary residence a couple of months ago...

 

2010 335d

145,000 miles, 0g ash, 0 regens since 120k miles :rofl:

 

Rocking a delete?

I wish there was an easy-to-implement delete for the E70.

 

Besides temperature and ash mass, what other parameters do you guys track with Carly?

 

I just caught or initiated a regen this morning on my way to work, 90% highway.
Soot mass was 27~g, cruise on 60mph, coolant around 76c, manually kept it at 4th and 5th depending on traffic.
I was running the parameters on carly and observed the soot mass go down slowly to .76g , nothing else changed. I dont think its completed yet, regen count is at 520 still.
I will try the same thing on my way home and see if soot goes to zero and regen count goes to 521.

I didnt observe anything drastic with the car while this was happening. The throttle pedal felt heavier when i had to speed up thats all i noticed.

UPDATE: On the next start up the number of successful regens went to 522 and ash didnt increase.

Ozer, take note of your MPG when this occurs.:yikes:

It about time to do the alphabet delete. I've been running with the SES light on for 20,000 miles or so. 6 motor control faults:

00492C Reducing agent, active temperature sensor, plausibility to low tank temperature to ambient temperature.

I fixed the last for nearly a year by flushing with distilled water. THe others I'm not willing to pay to fix, short of deletion.

 

What parameter are you guys using to get distance between regens in miles? Or are you just converting KM to miles?

 

Monitoring my Temps yesterday, I determined that my EGR thermostat had failed (temp 78 to 81 degrees) Went by the local BMW store to get one and was told they are no longer available. I fould some in the UK, but have to find someone who ships to the US. Amazon has a seller that will ship me one in April.

 

IIRC, the M57 engine in the USA doesn't have a thermostat for the EGR cooler, only a coolant thermostat for the engine. My '12 X5 35d is currently at my dealer getting its t-stat replaced and some other work done.

Good luck.

 

You are correct, there isn't an EGR thermostat on the US spec 335d. I just went and looked. That would mean the main thermostat is going bad and that's no 3 minute fix, like the EGR thermostat would be, if there was one.

 

An engine thermostat replacement is about a 5 hour job from what I've read in another thread.

My X5 35d has been reporting temps around 75C and they should be somewhere around 90C. The t-stat design temp is 88C and the coolant picks up a few degrees before it gets measured, so the reported temperature should be around 89-92C. With my X5 35d topping out at 75C, the temperature at the t-stat is a few degrees lower. My t-stat is toast and the car is at my dealer getting a new t-stat and some other work done.

You DO want to get the t-stat replaced so that the engine operates at the correct temperature so regens occur properly.

My car: 2010 X5 35d
Mileage: ~90k miles
Ash mass: unknown as I don't have Carley... but take 90k miles (144,841 km) + 157080 km of life remaining per Rheingold and I should have about 300,000 km of life out of the DPF... in theory.

 

150k miles DPF life is just a number, you reset the code at that point and carry on.

 

I was cleaning up my BMW docs and forgot I printed the following for the M57TU Diesel Engine.

At 4.5 Liter volume x 25 grams of maximum ash per Liter = 112.5 grams max.

 

Interesting. Thanks.

I started getting the 452A code around 150k miles, saying that the DPF is nearing End of Life. It is just an advisory notice so BMW dealer service can tell you that the DPF is approaching end of life and you should schedule an appointment for replacement.

I still have the 452A code and started getting the 4D4A code at 170k miles. An iDrive message about the DPF pops up and a yellow DPF symbol appears on the instrument cluster. The 4D4A code says the miles on the car has exceeded the calculated life of the DPF because the car continued to be driven and DPF not replaced after getting the 452A advisory code. The iDrive message and DPF symbol on the instrument cluster comes on once at 10 minutes after startup.

Regens are occurring like they should and I'm monitoring them with the Carly app. No issues with driveability. Power and MPGs are 100% normal. Everything is 100% normal except for the DPF warning 10 minutes after startup. It seems the car is starting to nag me more about the DPF.

 

how do you check ash mass?

 

It is a derived calculated parameter recorded in the ECU/DDE and available by interrogation by a code-reader like Carly for BMW by invini.

 

is it possible to do this using ISTA?

thanks

Mileage: 96882 miles
Ash mass: 28.98 g
Calculated remaining life: 134080 km
Regenerations completed: 241

Given the mileage on the car and the calculated remaining life of the DPF, I expect the car to trigger the 452A code around 150k miles. I expect the 4D4A code and DPF warnings to start around 180k miles.

I was getting weird value for coolant temperature i.e 8919C but when I chose engine temperature it showed 89C. Are you choosing engine temperature as coolant temperature?

I have had the 474C code once before and that was when my 12 X5 35d was calling for DEF and started the countdown to no-start. I couldn't find what the code meant after a number of searches. I think it IS related to the low DEF warning and unrelated to the DPF.

Good luck.

Strange parameter show up on coolant temperature - 8919 C. Please see attached file. Any advise?

 

What is motor temperature? I am on iOS/iPhone6s.

 

Highway at ~80 mph Motor Temperature holds steady 86/87°C . . . city driving always above 84°C

Currently on iOS 11.1, iPhone 6 . . . shortly switching over to iPhone X . . . :thumbup:

 

Via Carly Coolant temperature (Motor Temp) stays around 90C after 20 mins of city driving.
