bubba Posted April 3, 2007 Report Share Posted April 3, 2007 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 ??

gizze Posted April 3, 2007 Report Share Posted April 3, 2007 Probably yeah. Any flash of the ecu will overwrite the whole thing, so it will need doing again. Link to comment Share on other sites More sharing options...

wyliss Posted April 4, 2007 Report Share Posted April 4, 2007 [ QUOTE ] Thanks, now what do the codes mean.... [/ QUOTE ] 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. Link to comment Share on other sites More sharing options...

PetrolDave Posted April 4, 2007 Report Share Posted April 4, 2007 [ QUOTE ] So our cars have half a dozen ECUs now..... [/ QUOTE ] 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. Link to comment Share on other sites More sharing options...
