BMW Repair: tire changed - speedo not working, diagnostic scanner, speedo sensor

Question
I drive a BMW 318 wagon 2000, I recently had a flat tire which has now been changed (on the left rear side) however now the tire change light, abs and brake lights are on and the speedo won't work? Is there a way I can fix this without having to work into the workshop.

Answer
Tire change light? never heard of it!

Low pressure light maybe, if the tyre was replaced , hopefully they didnt change the valve as that is the sensor.

Set the tire pressures correctly (including the spare) and it should go out.
What brake light is on?

Dash board? back of the car? abs/asc?

Did the tire  disintegrate and harm the abs sensor on that wheel?
It is the speedo sensor as well.

You will need a diagnostic scanner to read the codes and to reset them after repairs.

Hope that helps
