PART NO: 34521164458. THE SENSOR IS ATTACHED TO THE BRAKE MASTER CYLINDER . 2.0 i, 2.2 i, 2.5 Si, 2.5 i, 3.0 Si, 3.0 i, M. Z4 (E85) 01/2002 — 08/2008. 1.8, 1.9, 2.0, 2.2, 2.8, 3.0, M, M 3.2. Z3 (E36) 04/1996 — 06/2002.
Just be weary of some of those ebay “genuine ATE” ones. I’ve gotten some in the past and it was obviously a hybrid unit where they dig out the old sensor keep the shell with the ATE markings and put back in a generic china made sensor part and epoxy them back.

I had the same earlier this year, codes on both sensors.
I found a guy from the UK on eBay selling OE sensors (they are made by ATE) at a great discount compared to the dealer prices (beware there are also Chinese clones being sold on eBay).
I replaced both my sensors (it can be done without removing the master cylinder, although it was kind of a pain in the ass).
And performed a brake bleed with a pressure bleeder and also bleeding the ABS/DSC unit with INPA.
Codes were gone and haven't come back since!
Afterwards I read online about the sensor calibration routine, but if I recall correctly I couldn't even find it in INPA?
So I didn't bother with it.
Hope my 2cents help.
Would you happen to have a link for the listing for the sensors? Thanks.

Thanks! Its not in INPA but DIS. Its also part of the foxwell scan tool.

Has anyone ever run the routine to calibrate the DSC pressure sensors? I got the DSC+Brake light today. Got code 5e24 along wit some others. When I view the live data the Front pressure sensor is like 2 bar bar lower than the rear. But pressing the pedal they seem to increase/decrease normally. I did recently tap into the brake pressure sensors for my data system, which I did on the last car and it has no effect like this.
When you run this routine it describes it as something you run after replacing the pressure sensors. Is it safe to try to see if the pressures normalize between the two circuits?
