Riz Posted September 13, 2003 Report Share Posted September 13, 2003 So Andy what does this actually do? And will it effect the car head unit? Onborad DIS etc? Cheers Link to comment Share on other sites More sharing options...
Andys3 Posted September 13, 2003 Report Share Posted September 13, 2003 All you are doing in clearing the ecu memory, basicly what the dealer does when he resets your ecu. It will clear your driving charistics and start from scratch. Through time the car adapts to how u drive, so if u are stuck in traffic a lot this will affect how your car drives over a period of time. After you had your car serviced did you think it drove better? If u did this was the reason. The only thing u have to reset is your clock and recalabrate your electric windows. Dont worry about that you just have to open and shut them a few times. It dosn't affect the DIS and the only affect to the radio is that it will be switched off, all u have to do is switch it back on. APR can fit this feature when they chip your car and you can reset with a push of a button.

khufu Posted September 17, 2003 Report Share Posted September 17, 2003 does the standard A3s ECU also adapt to driving style or is it just the S3? Link to comment Share on other sites More sharing options...
PreacherCain Posted September 22, 2003 Report Share Posted September 22, 2003 As far as I know, all the VAG Motronic ECUs are adaptive, in that they "remember" optimal timing and boost settings as you drive, as well as throttle-body settings. Also, if you have a newer DBW-type A3, you ought to be able to reset the throttle-body by switching the ignition on (just to the first position) and leaving it for 5 minutes. As far as the ECU memory's concerned, an application like VAG-Com or APR's system can reset it. Having said all of which, I haven't noticed a huge difference after having a dealer reset. Maybe I just drive too fast, all the time. Link to comment Share on other sites More sharing options...

Andy, does this learning of your driving characteristics change if your driving style changes, or does the ECU need resetting to do that? I've recently calmed down, somewhat, after getting my S3, and now feel the accelerator seems to feel a little like On or Off in Drive mode. This is probably how I was driving when I first got it as it was fun. As I seem to have changed a little, will the car eventually learn this, and adapt, or should I reset it myself?

Annodya Posted January 10, 2013 Report Share Posted January 10, 2013 ello dude1. remove negative lead for about 20mins and replace 2. Turn ignition to to first position and leave for 5 mins 3. start car and let idle for 5 mins 4. restart car and go dor a drive works for me I have a 2003 Toyota Camry and did a google search and found this thread. Thank you so much, this fixed the problem I was having. I took my car to Toyota and they said they didn't know how to fix it! The whole electric system was scewy, anything I touched that used the electrics, my radio would cut out, the lights would flick on and off and the clock would change settings etc etc. Sometimes if I was stuck in traffic the car would just die! When turning the key it would start again, but oh so annoying. This search was my last resort before trading the car in. Again thank you for such a simple remedy.
