Hi Guys, just had the second service on my 2.0TDi A4 today, and they mentioned it would need a software update to the ECU. I had it chipped about 12 months ago, would it have removed the program and reverted back to the original. I swear it wasn't as quick on the way home ?? /ubbthreads/images/graemlins/fekr.gif

Probably yeah.
Any flash of the ecu will overwrite the whole thing, so it will need doing again.

No idea my friend, they just did it. Anyone else shed any light on it .... and if my remap really has gone.

Does Will from performance torque still visit the forum ??

Basically the car has one main ecu which feeds off to five other smaller ones, this update is to ensure that if a problem arises with one of these units that the others will be able to cope without the car not starting.
As per the service technician at the dealer.

Just checked out my most recent VAG-COM full scan, and my B7 has guess how many ECUs?

TWENTY ONE!!!

01 - Engine 1
03 - ABS
08 - HVAC
09 - Central Electrics
11 - Engine 2
15 - Airbags
16 - Steering Wheel
17 - Instruments
37 - Sat Nav/Radio
45 - Interior Monitor
46 - Central Convenience - which has 4 sub-modules (1 per door)
55 - Xenon Range - which has 2 sub-modules for adaptive headlights (1 per headlight)
65 - TPMS
76 - Park Assist
77 - Telephone

And that's only the modules that can be seen from the diagnostics connector. There's others that can't.
