Hello from South Korea!
I’m a fellow Peugeot owner from Korea, still happily driving my 2011 508.
I’ve always admired the passion of the European PSA community, and I'm excited to finally introduce myself here.

For a long time, I was just a regular owner who didn't know much about mechanics and relied solely on official service centers for maintenance.
However, two years ago, I had a devastating experience when my engine block cracked. That was a turning point for me.

I realized that if I could monitor sensor data and practice preventive maintenance,
I could keep my car running longer and avoid such major breakdowns. This personal mission led me to develop PoBD-U.

(Caption: Running PoBD-U on faithful Peugeot 508 2.0 sw to keep an eye on its vitals.)

I wanted a tool that provides the specific, deep data that official apps often miss.
After testing it with a small community of 200+ owners in Korea and Taiwan,
I’ve now localized it into English and French to share it with the wider European community as a free tool for everyone.


[Why use PoBD-U?]

• Emissions & Exhaust: Detailed real-time monitoring for FAP(DPF) (Exhaust lines 1-3) and DeNOx/Urea (AdBlue) systems—prevent clogging and countdown issues.

• Deep Diagnostics: Read and clear fault codes (DTC) with specific ECU insights.

• Comprehensive Health Data: Insights into Fuel lines, Engine lubrication, Air intake, and Electrical systems.

• Clean & Ad-Free: No subscriptions, no ads, just the data you need.

[Technical Specs & Compatibility]

• Target: Urea-based (BlueHDi) models produced before april 2025.

• Supported ECUs: CMM_MD1CS003_Euro6_1/2/3/4, EDC17C60, DCM62, CMM DCM71.

• Hardware:Supports BT Classic, BT 4.0(LE), and Wi-Fi.

• Note: For the best experience on both Android & iOS, I highly recommend using a BT 4.0 (LE) scanner (e.g., Vgate iCar Pro).

[Download PoBD-U]

• Android (Google Play): PoBD-U - Apps on Google Play : https://play.google.com/store/apps/deta ... pplication

• iOS (App Store): https://apps.apple.com/app/id6743990865

• User Guide & Manual: https://elite508.tistory.com/

I am continuously optimizing the app and plan to support Euro 5, Petrol, and Hybrid models in future updates.
I would highly value your technical feedback and suggestions to make this tool even better for the PSA community!


N’hésitez pas à me faire part de vos retours en français, l’application est également disponible dans votre langue.

Thank you to the moderators for allowing me to share this tool despite the strict rules for new members. I completely understand and support the forum's cautious approach regarding external software.

As a fellow PSA enthusiast who has experienced a major engine failure, my only goal is to provide a helpful, transparent tool for the community. I welcome any technical feedback or security questions from the experts here. Thank you again for the warm welcome!

Hello, I installed the program on my Android phone and it works. My ECU is CMM_MD1CS003_Euro6_3 and it is supported. Thank you.

Hello and welcome!

Rather that dilute this thread as it's arguably off topic - but I'm interested to hear the story about what led to your cracked block - that's a fairly catastrophic and, to my knowledge at least, (thankfully!) pretty unusual failing, so anything you could share on that would be interesting

Hi Mihael_M, thank you so much for the feedback! It’s great to hear that PoBD-U is working perfectly with your CMM_MD1CS003_Euro6_3 ECU.

Actually, seeing that you are from Belgrade brings back wonderful memories for me. I visited your beautiful city about 10 years ago for an academic conference, and I still remember the warmth and hospitality I experienced there. It’s truly special to connect with a fellow Peugeot owner from a place I have such fond memories of!

I hope the app helps you keep your car in top condition. If you notice anything or have suggestions while using it, please feel free to let me know. Happy driving!

Thank you for your interest! It was a series of unfortunate events, and I’m happy to share the details.

The first sign of trouble was quite bizarre: during a routine check, I opened the hood and found that the coolant was actually overflowing, far exceeding the max level I had set. It was pushing back out of the reservoir.

Looking back, the root cause seems to have been a damaged oil filter O-ring during a routine oil change at an official service center. I went on a long-distance trip right after the service, and the subsequent oil leak led to a catastrophic chain reaction of overheating and pressure buildup that eventually cracked the block.

I’ve documented the symptoms and the lead-up to the failure on my blog (you can see the mess it made here: https://elite508.tistory.com/5 and the aftermath here: https://elite508.tistory.com/6).

That experience taught me that dashboard gauges often react too late. I developed PoBD-U to monitor those "invisible" live parameters—like precise cooling pressure and DPF soot—so I can catch even the slightest abnormality before it leads to another engine-out scenario.

Hi 508_lion , I have questions. On your video display with your program, the Exhaust Line information 2 section shows Distance traveled since last regeneration and Average distance last 10 regeneration. I don't see that part on my car. Is the regeneration method the same for you and me since I don't have Eolis?

Hi there, I'm looking for this kind of app for a very long time, I tried many many apps free or paid but none of them provided information that I needed, and that is the DPF / FAP status - detailed information. Unfortunately this app doesn't support my engine. My engine is a DW10FDCU engine 2.0 BlueHDI Diesel 180 hp with FAP/DPF 2019 it is a Citroen Jumpy Spacetourer. What are the chances that it will be supported? currently the app said that ecu is not supported. Thanks

It would be nice if 508_Lion would also help. There is a section on his site where you can submit a request for unsupported ECUs. The site is in Korean but can easily be translated into English.

I must have missed this when I read your post earlier.

I had a similar, but different experience from yours.

I don't think we ever discovered the cause of my problem with the car, so I can't give any details. But the cooling system of my 604 2.3 litre turbo diesel probably overheated, but whatever it did first, it then overflowed. And boiled dry.

The temperature gauge on the dashboard showed that everything was normal. The temperature of the engine was sitting in the middle of the range, just where it should be.

Then the engine stopped. And I had no idea why. Until the engine cooled and I was able to remove the cap of the radiator.

Most cars do not fit anything that warns the driver about low or no cooling fluid. I fitted a warning buzzer for low cooling fluid after that experience.

Interestingly my 1999 306 HDi, 2004 206 HDi both have coolant level sensors. Can't recall if the C5 does (or the 308s, will have to check!)

On the 306 you just get a red warning lamp, on the 206 from memory you'd a message on central screen plus a beep and the STOP lamp all activated.

My previous earlier 1995 306 had no level sensor (and had cooked and cracked it's head just prior to coming into my ownership!)


Did your 604 live to fight another day?

[mickthemaverick]

My 1959 Morris 1000 had a low level sensor - it used to blow steam out of the radiator cap when things went wrong!!

I don't know how I missed this question, sorry.

Yes, the 604 did live to fight a few more years. It had to! It was my only transport for a number of years. But it was a major rebuild by a diesel mechanic who I don't think had ever worked on cars before. And certainly not Peugeots. He had an old Volvo (petrol), but I don't think he worked on that, either.

My first 306 Cabriolet would have been saved if it had had such a thing.

"I’m sorry for the late reply; I didn't receive a notification and wasn't aware of your comment.

Regarding the data, depending on the Engine ECU, the items 'Distance traveled since last regeneration' and 'Average distance of the last 10 regenerations' may not be provided.

It has been confirmed that these items are missing in some of the latest vehicle ECUs (such as the CMM_MD1CS003_Euro6), at least according to Diagbox. It seems they may no longer be necessary because DPF regeneration intervals have become significantly longer."
