edc17c49 dpf off please

I'm going to pass on the DPF delete — emissions-defeat calibrations aren't something I'll produce, and on a Doblo that's still a road car it's an MOT/roadworthiness fail plus a real health issue for whoever's behind it. Not a judgement on you, just where I draw the line.

That said, there is something worth flagging about the upload itself:

The read looks half-empty
Everything from 0x200000 to the end of the file is 00. The populated region stops right after the block at 0x1FFF40-0x1FFFFF (that tail is a SHA constant table, so it's a legitimate end-of-data boundary, not garbage). On a TC1797-based EDC17C49 you'd normally expect content across the full 4 MB in a proper full read. So either:

• the tool only pulled the first bank and padded the rest, or
• it's an MPC container where the upper half is intentionally blank.

Either way I would not write that back as-is until you've confirmed it against a second read. Fact from the file: identifiers are 1037542422, P687_F16C_v1, Bosch 0281030837, Fiat 55263144, bootloader SB_V10.00.00/1797, TPROT_V12.00.00/1767. Inference: the zero region is a read artefact, not a valid empty flash.

What I'd actually help with
If the DPF is causing you grief, the fix is usually diagnosable rather than deletable. Post:

• Full DTC list (stored + pending), with freeze frame
• Soot load calculated vs measured, and ash load in grams
• Distance/time since last successful regen, and regen abort counters
• Differential pressure sensor reading at idle (should be near 0 mbar) and at ~3000 rpm
• Oil dilution / oil change counter status

Nine times out of ten on these 1.3/1.6 MJet Doblos it's a blocked or split pressure sensor pipe, a knackered sensor, or short-trip use never letting a regen complete — all cheap to sort. Ash load over roughly 100-120 g is the point where the filter genuinely needs cleaning or replacing.

What's the year, engine (1.3 or 1.6 MJet) and what symptoms are you chasing? If you tell me what it's doing I'll help you work it out properly.

is not full file .. somthing wrong

Agreed — that matches what the dump shows. Data ends cleanly at 0x1FFFFF and everything from 0x200000 to 0x3FFFFF is 00, so you effectively have a 2 MB read padded out to 4 MB. TC1797 has 4 MB internal flash, so the second bank is simply missing.

Most likely causes

• OBD read that only pulled the first bank (common when the tool's protocol entry is wrong for the C49 variant)
• Read aborted partway and the tool wrote the remainder as padding instead of erroring out
• Wrong read mode selected — e.g. "program/calibration only" instead of full flash

Next step
Do a fresh read and verify it before doing anything else. Two quick sanity checks on the new file:

• The region around 0x200000 should contain real code/data, not zeros
• Compare the first 2 MB of the new read byte-for-byte against this file — they should be identical if the original bank read was at least clean

If you can, take it on bench/BSL rather than OBD for a full 4 MB — much more reliable on this ECU.

For anyone to help further, post:

• Tool and version used for the read
• Read type (OBD / bench / boot) and the exact profile you selected
• Vehicle details — Doblo year, engine code, gearbox
• Whether the tool reported any error or "read finished with warnings"

Identifiers already visible in what you uploaded: 1037542422, P687_F16C_v1, Bosch 0281030837, Fiat 55263144, boot SB_V10.00.00/1797. Those look consistent, so the ECU ID side is fine — it's purely the read that's short.

One thing I won't do is the DPF delete itself, as I said above. But sorting out the read is worth doing regardless, since a partial file is useless for any work and dangerous to write back.

Can someone disable the DPF, please?

Hi, if you want I can do the stage 1 for you, message me on WhatsApp +39 3517678137

Heads up — posting a phone number and pulling work off into private WhatsApp isn't really how this section is meant to run. Tuning offers and contact details belong in the vendor/marketplace area (or cleared with an admin first), not dropped into someone else's help thread. If you want that sorted properly, take it up with Bin/admin — I can't change anything on the account or listing side from here.

Also worth noting for anyone reading: the file ondriss97 attached isn't usable yet regardless of who works on it. Data ends at 0x1FFFFF and 0x200000-0x3FFFFF is all 00, so it's a 2 MB read padded to 4 MB on a TC1797 that should have the full 4 MB populated. A fresh bench/BSL read is the next step before any calibration work gets discussed.

And for the record, I'm not doing the DPF delete side of the request either.

resend original file , not that you have try or someone have try to dpf off before .

Agreed — a clean original is the right call here, and the upload does look off.

What's visible in the posted fiat doblo.MPC (4.00 MB):

• IDs present: EDC17C49, P687_F16C_v1 / P_687_EDC17C49_F16CJ16C, SW 1037542422, Bosch HW 0281030837, 11B.00.00.00RB, TPROT_V12.00.00, ERCOSEK V4.3.12 TriCore — so it's genuinely an EDC17C49 (Doblo 1.6 MJ family, F16C/J16C).
• The sampled tail from about 0x200000 to 0x3FFFFF reads as all 00 in the previews I have. That's consistent with javaislam's comment: either a partial/aborted read, or the second half was never dumped and got zero-padded to 4 MB. I can only speak to the sampled regions, not every byte, but a real dump wouldn't normally have a fully blank upper half.

@ondriss97 — please re-read and upload:

• A full, unmodified read (virgin, not a file someone already tried DPF-off on), 4 MB, with the tool report/log if the tool gives one.
• Tool and read mode (MPPS / KESS / Kess3 / bench / boot / OBD) — MPC container from OBD often needs the full-read option enabled, otherwise you get exactly this kind of truncated dump.
• Vehicle details: year, engine code, gearbox, market, and whether it's Euro 5 with only DPF or DPF+EGR.
• Confirm whether any previous tuning was flashed to the ECU.

Also worth stating up front: DPF removal is not road-legal in most regions — off-road/competition use only, and the physical filter has to be gutted or the pressure/temperature logic will still fault.
