Im not sure but galletto cant read me7 outside bootmode.
Try to use me7flasher with your galletto cable.
You need to remove the cluster fuse before read or write.

Use a cheap Blue ebay Vag com cable, Download the Nefmoto software . Chose from Devices your Serial-->USB cable , then go to KWP2000 flashing , Choose memory layout "29F400" , then press Full read Flash.

Removing the cluster fuse is a good idea if you still have problems.

Not true.. Galletto works fine via obd on most me7 ecus

I have had issues though with the apx Ecu and galletto but mpps (clone or not) worked fine

hello,

thank you all for your help.

I have made ​​some success with blue cable....
but I have not full success with Reading

what is meant - cluster fuse removing?
control unit fuse put out and turn the key 

@littcos
MPPS works definitely with APX?

thank very much for help!

Open the fuse box inside the cabin You can see the panel when you open the driver`s door.
Remove the plastic ,search for the Cluster fuse.Usually there are 2 fuses ,since you are not sure which fuse ,
remove them both.

If still is a no go ( I had as similar expirience with a BAM TT , couldn`t read it no matter what ) you have to BOOT your ECU,search the wikis and you will find info

Hello

I am very happy! I have read my TT 8N APX ECU!

I have tasted 4 hours long yesterday with my new MPPSv13 cable.
cable has not worked.
fuse for Dashboard put out - no go
fuse put in - no go
fuse control unit (there are 4 pieces) put out - no go

important for all who want to read the APX ECU:
Read the ECU works only with a cable MPPS
- fuse for Dashboard put out (only this one)
- Turn on key
- listening that the petrol pump does not run
- fuse plug in
Reading works!

Thank all for help !

my file is here atatched
according to my previous owners this is tuned of 265 hp
1.3 bar boost pressure
(with my Iphone-DashCmd I have 250hp measured)


somebody please a XDF for me
the published here are not for APX ECU from 1999

Thank very much

one more question - MPPS program corrects the checksum correct?
