There is some easy troubleshooting you can do if you got a voltmeter.... The pressure sensor they are talking about is located on the PSM itself (plug with three wires, one black, one red and green, one black and brown)

I believe I had this code. Fixed with replacing brake light switch on brake pedal. Its the switch that turns on the brake lights when you press down the pedal, I believe. It is a very inexpensive part.

thnx a lot guys for your info's. but I checked already step by step and there were ok. brake light switch also replaced. I wonder if the metalic brake line set could cause this problem or the pre load pump (just in your pic under the main brake cilinder)?

Just realized your bleeding sequence is not as per repair manuel. RR,LR,FR,FL...Finish with the nearest to the reservoir.... But I doubt it is part of your problem.... If you got access to Durametric V6 you are suppose to be able to start the booster pump. ( I was not able may be due to a slow laptop...) and once the pump is started you are suppose to bleed the front right....

Can you take a moment and explain the pressure button, level, location and purpose. Thanks!

The switch has a plastic plunger type button that activates the brake lights. Before you install the switch on the brake pedal you need to set the appropriate level for the button. It adjusts by sliding to plunger into the housing or pulling it outward. I set it up kind of by trial and error. It finally worked and the ABS/PSM 4460 quit returning.
