I’m currently working on a Škoda Fabia III 1.4 TSI (CZCA engine) with a Bosch MED17.5.25 ECU.
I’ve already got full reads (EEPROM, Flash, PWD) and I’m building my own WinOLS project, but a proper DAMOS or A2L would save me a lot of time and guesswork.
If anyone has a matching or close DAMOS/A2L file and is willing to share, trade, or sell – please hit me up. I’m not looking to freeload, just trying to learn and improve my tuning workflow.
Thanks in advance,
Andy
(P.S. I’m also interested in DQ200 TCU definitions if anyone’s got something useful.)
Need some help please. Recently, I filled the car with original VW/Audi Adblue fluid (DEF). After short driving the MIL light turned on, and two DTCs logged on the ECU, nothing on Reductant Control Module. Shortly after, the AdBlue Fault message turned on indicating 200 miles to drive, even though the tank was almost full. I've tried to troubleshoot the problem, but I can't figure out what is causing it. I cleaned and tested the DEF injector, drained and refilled the AdBlue tank with brand new fluid. Tried to reset SCR components with VCDS. Cleaned the NOx sensor installed on DPF. Nothing helped. I don't know what else to check, AdBlue pump? It seems to work OK.

I have EDC17CP44 clone of my car's original ECU. I wanted to use the clone ECU for AdBlue delete modification. I have the modified flash with Davinci of the original ECU, and uploaded it to the cloned ECU. The car does not seem to start up, it's just constantly cranking. Is it OK to use the modded flash from the original ECU on the cloned ECU? The model of the ECUs is the same: 4G0-907-401-N.
Aliexpress seems to be flooded with these Link G4s that I assume are clones. I see all other kinds of ecu/piggy-back too, I suspect some products are old original models with new packaging but they cant all be.
HELLO.
I have a problem that the manual air conditioning does not work.
The compressor version does not have a clutch, only with a valve.
After turning on the air conditioning, there is no compressor response. No valve control.
In the diagnostic interface. Pressure on the sensors 6.6bar, After pressing the switch, the air conditioning is enabled. However, if the compressor is turned on, it is set to OFF. 0% valve filling.
Can anyone suggest where to look for the fault?
Does anyone have a diagram for manual air conditioning?
I have a problem with Volvo XC90 adaptive headlight.
First of all, headlamps work fine (high beam, low beam and turn signal).
Also, when I start the car, right adaptive lamp does not move up and down and right and left (left lamp does this thing after a startup) and i get an adaptive headlamp malfunction
error in the dashboard. When I turn the steering wheel - the lamps do not run to the turning location
Diagnostic shows this - CEM -U132382 adaptive headlamp module right.
I have removed a working lamp complete and plug on the front right but still U error shows still. I also removed the headlamp control unit AHM and install it on the left headlamp and
the error do not show up at the left side. Now i scoped the LIN bus line of right headlamp and i compare it to the left, everything is fine and the signal square wave is same. cem
update was also done but yet still the error is there, please if someone solve this thing some before, help. thanks
I see the foxflash team have come out with padflashr which seems to be a bflash clone/reskinned foxflash tool but not much review on it so am going to document my experience here so you can all see how it goes;
I have been wanting to move away from my Autotuner slave for a while, i do not have the money to convert to slave and wish to slowly move into the tuning/locksmiths side so need for master tool is strong!
23/04/2025 - pulled trigger, paid £516 for Padflashr on foxflash own website, instantly received device serial number which is Foxflash s/n (FFxxxxxxx)!!!
Will update as and when device arrives
my test ecu is ME9.7 from 156 w204 c63
I have a problem, while flashing the ecu with 4G2907311c 0007 (odis engineering) it stopped and now car does not start. The coding of the ECU is now 00000, i tried to SVM with odis online and it could not write the coding area.
I made a full BDM read out with foxflash, maybe somebody can correct the coding area. The codeing from Audi server is 12 25 40 12 05 36 01 03 00 00
Hi, I have an Adblue fault on a 2018 Citroen C3 Aircross which doesn't clear after refilling or resetting, so I would like to do an Adblue delete. Can anyone help?
I could use some help in programming new virginized ECM SIM271DE2.0 ECU with Xentry.
I am able to retrieve the .exf file from call queries in Controll Programming Menu,
I really appreciate if someone can help me, or at least tell me who to contact to.
