No.2 Speed sensor for my A340e?

[aloshan]

Hey guys

So after replacing all 3 solenoids , and the no.1 speed sensor behind my digi dash my erratic shifting problem still exists. Ive checked the wires to the no.2 speed sensor and they seem to be fine so I'm thinking the fault lies with the speed sensor unit itself. Does anyone have the part number , oem or aftermarket of a speed sensor for the a340e or any idea where I could get one?

thanks in advance

I have heard some rumours that the no.1 speed sensor(the one behind the digidash) is the backup if the no.2 speed sensor fails.
does anyone think its worth disconnecting the no.2 sensor to see if no.1 sensor (which I hope is working) starts doing its job...just until i can find a replacement no.2 sensor?
