Galletto v54 EDC17 Questions & Answers:


Q: Galletto works fine on VW EDC17CP14ecu?

A: Yes


Q: with edc17cp10 psa no problem read/write but with this cp14 vag not work even in bootmode and obd ( read ok in both)

A: CP14 shouldn’t be problem on Tricore boot. I think you have broken ECU or device.


Q: Galletto v54 checksum not supported, how to do?

A: 0. Read Original ALL with Galletto boot mode. It will give you “All” file (4,224kb), internal flash+external flash+eeprom, (in my case).
1. Paste mod internal flash (make sure checksums are already correct) into the original ‘all’ file. Align correctly. Internal flash starts at 00, so it is easy.
2.Triple checkthat the paste is ok!
3. Flash modded “all” file in Galletto. This is done using “Write All” button.
4. It takes much longer to flash a file with differences. It took about 6+ minutes on first part – internal flash. It went to 100%, then to 75% and up to 100% slowly many times. Total over 10 minutes.
5. Read All to verify!
6. Compare with Hex Editor.

Car started, DPF functions are all gone.


Q: Is it possible to attempt to flash the big 4.2 MB ‘all’ file (int flash, ext flash, eeprom combined)?

can I paste my changes there, and checksums too?

A: The answer is YES

I flashed the original 4224kb ‘all’ file back to the ecu successfully. Galletto skips checksum correction for the ALL file.

Risky, but I guess I was brave enough. The boot pin accidentally untouched, and galletto stopped and told me to remove power and reconnect. WHILE FLASHING. Nearly peed my pants.

I repositioned boot pin, reconnected power, and it continued error free!

After, I did a verification read of all.

100% identical to original

Now I will paste my internal flash mods (with checksum corrected already) into the 4224kb file, and flash that.


Q: How to delete individual dtc codes from edc17 (cp14 was the flavor i was working with)?

A: example:

009298 – Diesel Particle Filter; Differential Pressure Sensor

P2452 – 000 – Elect. Malfunction – MIL ON


find the p code in the p code look up table. 16bit, hex.

location: 190a7a

p code table start: 190654

get your hex calculator!

190a7a – 190654: 426. divide by 2, 213.

find your vag specific dtc look up table. 8 bit.



table start location: 18569e

18569e + 213: 1858b1. this is the location of the p2452 dtc. 00 this byte.

no more dtc light.

same process as me7 except /2 instead of /8.
