Hi guys, I've noticed lately that sometimes when I start the car up the power button light flashes 16 times. The button itself is always set in the middle, I don't bother with it.

The car shifts fine and haven't had a problem with it except a couple times it wouldn't shift up until around 4-5,000 rpm when it was really cold.

Anyone know what the flashing means? I'm taking it for a service and shift kit install soon but would like to know what the deal is before i do it.

Cheers!

See if this helps..

Enter the auto transmission diagnostics mode:

  1. Have the car at normal temperature in Park with the overdrive on
  2. Start the engine the power light will go out after 2 seconds
  3. Turn the ignition off
  4. Move the selector to Drive (you may have to use the push button release)
  5. Overdrive off
  6. Wait 2 seconds, and turn the ignition on
  7. Wait 2 seconds and move the selector to 2
  8. Overdrive on
  9. Move the selector to 1
  10. Overdrive Off
  11. Press the accelerator fully and release

Auto transmission diagnostics codes:

The error codes are flashed out using the Power light on the dashboard (R32) or the Power / Snow button (R33). The sequence starts with one long flash. If everything is OK, this will be followed by ten short flashes. Errors are indicated by a long flash in the sequence of short flashes.

1st flash longer Revolution sensor shorted or disconnected

2nd flash longer Speed sensor shorted or disconnected

3rd flash longer Throttle sensor shorted or disconnected

4th flash longer Shift solenoid A shorted or disconnected

5th flash longer Shift solenoid B shorted or disconnected

6th flash longer Overrun clutch solenoid shorted or disconnected

7th flash longer Lockup solenoid shorted or disconnected

8th flash longer Fluid temperature sensor is disconnected or the control unit power source is damaged

9th flash longer Engine revolution sensor shorted or disconnected

10th flash longer Line pressure solenoid shorted or disconnected

All flashes the same with no long start flash - Battery voltage low, has been recently disconnected or control unit has just been reconnected

Hi just had a similar problem to yours when I did my sub but the only prob was I could not go up past 3 gear I checked the power and snow switch it was not pluged in I just plugged it in and it was fine again also when they dyno these cars they disconnect the power and snow switch to stay in 3 gear. I hope this fixes it for you to

didn't answer question what does it mean power button flashes one long sixteen short and the car only selects third gear like it is in failsafe mode

      Yeah so when you turn key to IGN the fuel pump should run for a few seconds. If you find the fuel pump relay (and have a multimeter, and a second person) to can check the relay inputs.  One trigger pin should be either fully earthed  The other trigger pin should get 12v from the ECU for say 3 seconds when you turn key to IGN, and at all times that key is at START (note, I said this from memory, it may be the other way around, ie one pin always has IGN 12v and the earth has continuity to earth when you turn the key) One Pin should have a good battery voltage The last pin goes to the fuel pump + Also note that if the power to the relay is good, and the relay is working, it is worth checking the pump has a good earth too. There is a computer in the standard system that increases the earth resistance to slow down the pump when not required, pretty old school and it may have failed

      All this talk about fuel and fancy ECUs, meanwhile my poor old R32 has neither.... When the ignition is turned on, should there be power running o the fuel pump constantly or just for the few seconds it usually takes to prime the pump? About to go have another look at it, have watched some YouTube vids on how to use a  multimeter and looked at some wiring diagrams but really have NFI what I'm looking for because electricity is invisible

      Yuh....but weren't all the supertourers, except maybe the Audis, FWD? I don't recall any of the others being AWD.
