how is the computer reset on a ed?

disconnect the battery for 10 mins or so

thank you

This has been covered so many times. All that happens when you disconnect the battery is the KAM (keep alive memory) is erased and then it runs rough for about a week, in the end you are right back to start before erasing it. So basically its a waste of time and had no benifit. Also by disconnecting the battery the throttle calibration has to be done otherwise the gear changes if automatic could be harsh.

NOTE DO NOT TOUCH THE ACCELLERATOR DURING ANY PERIOD OF THE ADAPTIVE PROCESS.
The correct way to set idle speed after battery disconnection is:
1. Run engine until operating temp reached and thermostat opened.
2. The engine should then be idled for approx 1 minute in each of the following conditions (total idling time approx 4 minutes)
3. Neutral with all electrical loads OFF.
4. Neutral with Air conditioning ON.
5 Drive with all electrical loads OFF.
6. Drive with Air conditioning ON.

After all this has been done then proceed to go on and to do these steps which actually set the TPS values;

5. *To set the closed throttle reference position, place the transmission
in Drive, Air con off, and let the engine idle for a minimum of 1 minute.
6. Next, set the wide-open throttle reference position by turning the
engine off- but leave the ignition switch to the "ON," position, ie;Idiot lights on etc, then press the accelerator
pedal to the floor and hold it their for 1 minute, minimum.
7. Then Place the gear selector to Park and switch off the ignition.
8. Drive the vehicle and check for proper shifting patterns.

Someone please write this all up properly and make it sticky. Lets get all the general questions like this and the little spanner question and put it all in here.

eg

REMOVING THE LITTLE SPANNER ON THE DASH
Turn car to ON position. Press and hold the reset button for 10 sec

and so on

Great idea but there is still people that ask the same old questions like "what oil should i use"

or what coolant is the best for ????

and questions like "whats the procedure for a manual"..... Anyone?

and questions like "whats the procedure for a manual"..... Anyone?

How many sensors are there in an xf EFI model? Are they expensive to buy? Are they easy to change? If you change them..all of them, do you have to do anything so the computer "knows" that it has been done? And has anyone done this before, better or worse? Do sensors have a "life expectancy" ?

I second that

how about a FAQ i6 section..that way the forum doesn't get infested with sticky's at the top of the screen and threads don't disappear as quickly to page 2.
