Hi all,

Looking for info on any XDF file compatibly with an allroad 2.7t tip

   0261207137         ECUHN         
   1037360858         ECUSN         
   4Z7907551D        VAG part number
   0002                   VAG sw number   
   2.7l V6/5VT         engine id     

Any info or a point in the right direction appreciated

Why not flash to a more well defined file?

4Z7907551R should work and is pretty well defined

Mhhh. I was under the impression that all 4Z ones have different wiring harness
and are all 7.1.1.

So will a 551R file be compatibile? On the wiki it gives a list of the ecu files and correndsponding engine codes etc. a 551R appears as me7.1 in European form but as me7.1.1 on North American form.

So do I have to look for a EU 551R xdf?

Also an EU 551H is very similar is there an xdf available for this, tried a search to no avail.

And doing more searching in the wiki it seems that the 551M or mbox is compatible for an all road my model year and tip transmission, can someone verify this so I can get this show on the road?

Any info appreciated
Thanks

Ok Thanks for all the answers Nyet.

My understanding now is I’m looking for a well defined xdf starting 4z..... and is me7.1 to match my Ecu or am I still understanding wrong? 

If I am correct (doubtful), are there any good xdf files to suit?

Thanks

Again Thanks for the reply. So I can use the 8DO 551L or L box definition file from a s4? Even though my Ecu is 4Z7 551D?

If so excellent and thanks for the all information.

As for the immo problem, will I have to deactivate the one on my allroads 95040 chip or could I just write over with an L box xdf and it will be deactivated (hardly think it’s that handy)

Thanks

Perfect,all set now to go ‘L box’. I read Ecu eeprom with Argdubs tool prior to flashing.

Now another problem arises, flash successful with rear 02 delete and sai delete  and slight tune and car starts then dies. I am presuming this is an Immobilizer issue.

I will start another topic in the appropriate section (newb questions/issues)

Any help will be appreciated greatly and thanks for all the help so far
