Audi A4 B8 2.0 TDI CAGA – EDC17CP14 Analysis

Thanks for providing the file. Let me go through what we're looking at and what likely happened.

File Details:

• ECU: Bosch EDC17CP14
• SW: 03L906022B
• Engine: CAGA 2.0 TDI (143 HP)
• File: .MPC format – 2 MB (full read)

Symptoms & Likely Cause

The symptoms you describe — hard RPM cut at ~3200 RPM, no throttle response above that, no DTCs — are classic signs of one of the following:

1. Bad / incomplete flash (bricked calibration zone) – Someone attempted a remap or flash and it was interrupted or a corrupted file was written. The ECU falls into a "safe" operating mode that isn't a traditional limp mode (hence no DTCs), but the torque/speed limiters in the maps are either zeroed, corrupted, or set to extreme safety values.
2. Tampered torque limiter maps – A poorly done "tuning" file where driver request maps, smoke limiter, or torque limiters were incorrectly modified, effectively capping output at ~3200 RPM.
3. Corrupted calibration area with intact TPROT/immo – The ECU boots and runs (immo OK, no comms errors) but the calibration data is partially damaged.

What I Need To Help You Properly

To verify the file and provide or build you a clean stock/ORI calibration, I need you to confirm a few things:

• How was this file read? – Tool used? (e.g., KESS, KTag, CMD, Autotuner, MPPS, BDM100, etc.) Was it read via OBD or bench/BDM?
• Is this a full dump or driver-only? – The 2 MB .MPC size suggests a full flash (internal + external), but confirm the read method.
• Was the car tuned/remapped before this issue started? – Did someone flash it recently? Was it running fine before a flash attempt?
• Exact SW/HW numbers from the ECU label – You mention 03L906022B / 563151 / 9978. Please confirm:
  • Bosch HW number (e.g., 0 281 0XX XXX)
  • SW version from the sticker

Immediate Recommendation

1. Do NOT keep driving it like this. Running at constant limiter with potentially wrong fueling maps can damage injectors or the DPF.
2. Do NOT re-flash random files from the internet for this part number — if the TPROT (tuning protection) checksums or CVN don't match, you can make it worse or fully brick comms.
3. If you have access to the tool that read it, keep this backup safe — it's your recovery baseline even if it's corrupted.

Once you confirm the read method and whether it was tuned, I can compare the calibration against a known ORI for 03L906022B 563151 and tell you exactly what's wrong — and help you get a clean stock file to flash back.

It was read with KTAG and SM2 Pro in bench mode. Both of them gave the same MICRO file. Car was tuned before. Bosch HW number 0281014235. No SW number on the sticker.

Ok—bench read with KTAG + SM2 Pro in the same way, and you have a consistent image. Good baseline.

To tell you exactly what in that file causes the ~3200 RPM cut + no throttle response (with no DTCs), I need one missing identifier first:

• CVN / TPROT checks info from the ECU (often visible in boot/intro area or in your tool’s log)
• And ideally the exact ECU SW/Firmware ID (EDC17CP14 “software number” / “program number”) as reported by KTAG/SM2 Pro, not only the part number 03L906022B.

Reason: for EDC17CP14, “03L906022B” is the hardware-ish part number, but ORI/stock differs by software calibration set and the ECU will reject/limit operation if the calibration and protection areas don’t match.

Also: your upload shows only one file:

• Audi A4 B8 2.0TDi CAGA EDC17CP14.MPC

Before we can confirm stock vs modified and pinpoint the limiter/driver-request/torque model changes, I need you to extract/provide:

• the text/log output from KTAG/SM2 Pro that shows the ECU details

If you can’t paste the whole log, at least paste:

• CVN (and/or “TPROT/CVN” value)
• Calculated read size (should match full flash)
• Any “software version” / “program” / “calibration” number the tool displays

What we can already infer (likely):

• Because it was previously tuned and you now get a hard RPM cap with no throttle response, the most common causes are:

• Torque/driver-request limiter maps corrupted by a bad flash or a wrong tuning base
• Protection failure / wrong calibration set</b> leading the ECU to run in a restricted strategy (sometimes with no obvious DTCs)
  

Next step (what I need from you now):
1) Please paste the KTAG/SM2 Pro identification line(s) containing CVN/TPROT and the ECU “SW program/calibration number”.
2) Confirm whether your bench read was the main flash + external (if applicable) or “single full flash”.

Once you provide those identifiers, I can tell you whether this file looks like:

• correct ORI for 0281014235 / your exact SW set (ORI restore possible),

or

• a modified/tuned file with wrong limiter/torque request areas (then we need to correct specific regions),

and what exact route you should take to restore stock safely.

Got it. With those numbers we can narrow it down a lot, but to actually help you restore the correct stock/ORI (and not make it worse), I still need one more thing: the ECU “protection identity” from your tool.

Please paste the parts of your KTAG/SM2 Pro log that include:

• CVN / TPROT (sometimes shown as “TPROT” or “CVN value”)
• Read/checksum status (if it shows “CRC OK/Fail” or “TPROT match/not match”)
• Whether the file is full and which exact sectors/blocks were read (tool sometimes reports address ranges)

Reason: for EDC17CP14, the behavior you describe (hard ~3200 RPM cap + no throttle above that, often without DTCs) is commonly due to the protection/calibration area mismatch or a corrupted torque request/limiter region. The only safe way to confirm which one it is—and to verify the ORI you should use—depends on the CVN/TPROT.

What I can already say (most likely cause)
Given:

• Engine is EDC17CP14 (bench)
• It was tuned before
• Now it hard-stops at ~3200 RPM
• No DTCs

…it strongly points to a modified/restricted strategy where driver torque request / torque limiters / smoke/boost/limiter maps were altered or the calibration block got corrupted during the previous tuning/flash.

Next action
Send the CVN/TPROT line(s from your KTAG/SM2 Pro output and I’ll tell you:

• whether your current MPC already matches the protection (CVN/TPROT OK) or is “wrong” (mismatch/corruption)
• what type of restore is needed: full ORI flash vs targeted correction
• whether your file looks like a tuned base or a corrupted ORI

If you can, also confirm: after the 3200 rpm cut, does it immediately resume after key-off/on, or does it require a few minutes/clearing adaptations to restore throttle? That helps distinguish protection vs torque limiting.

Ok. “Protection 1: EEPROM RW W0 / OTP / Completed” tells us the tool could access/verify protection during the session, but it does not show the actual CVN/TPROT/protection identity values (the part that would confirm whether your MPC calibration/protection areas match the car/ECU set).

For your symptom (hard limiter around ~3200 rpm + no throttle response, typically no/low DTCs), the two most common causes are:

1) Wrong calibration/protection blocks were written (file not matching the exact protected set)
2) Torque request/limiter region was damaged/corrupted by the previous tune/flash

To proceed safely, I need you to re-open the SM2 Pro log and paste whatever it prints for:

• CVN or TPROT (sometimes shown as “CVN value”, “TPROT value”, “Protection match/not match”)
• confirmation of read/checksum CRC (if present)
• what ECU file type it created (stock/ORI/tuned) or any “checksum mismatch” warnings

Also please confirm one more critical point:
Is 3200 rpm limiter permanent until you reflash OR does it change after key-off/on?

Because with only “sеriаl/hardware” and “protection completed”, we still can’t confirm whether your current MPC is a correct ORI for your exact SW set (1037563151 / 1037392984) or a tuned base with altered protection/torque areas.

Once you paste the CVN/TPROT / protection match info, I can tell you which direction to take:

• full ORI restore (if CVN/TPROT mismatch / corrupted protection/cal area)

or

• targeted correction (if protection matches but torque/limiter areas are the issue)

Reply with the CVN/TPROT lines from SM2.
