Abs Esr esp problem

[Lingo09]

Hey when i start the car nothing is wrong,
but when i drive 10 meters then the signal : abs esp asr is malfunctioning.

All this happened 30 minutes after a Automatic carwash.
does anyone have any idea what this could be ? 
Sensors ok and breaklights are working.

Water got into the BSI perhaps?

Could also be water has gotten into one of the abs sensor plugs. Did you have the underbody wash? The plugs should be watertight but it's possible one is not.

Ideally, and I keep harping on about this but it's true, you really need a Lexia 3 interface and Diagbox software to properly diagnose a fault on a Citroen, especially on the B9. They are very reasonable prices on eBay (get the full chip version) and the only issue people face is getting it installed properly. Ideally needs an older win7 notebook or laptop.

A notebook is ideal as the battery tends to be longer lasting. You can, if you have a win10 laptop, install it in a virtual machine copy of win 7 or install it to a bootable Win 7 USB using
the Rufus app. The you boot from the USB with Diagbox installed on that, and boot with it unplugged to go back to win 10.

Unlike the generic abs warning, Diagbox will tell you exactly what is actually wrong.

can you recomend a Lexia 3 interface and Diagbox software .as i could do with one as well . thanks.

I got mine on eBay, search "full chip Lexia" or "full chip Diagbox" and take it from there mate. Loads for sale, just get the lowest priced UK seller who declares it's the full chip one as the non full chip models can't do everything you may want.

Here's the one I got a while back, Hong Kong seller but most are based there with UK stock:

So i bought a diagnostic machine.
And i get this error.
Do you guys think it is something wrong with the switch in the image? Or is it a different one?
Thanks!

[Sol]

Not much to go on mate. the brake switch on a RHD vehicle is below the glovebox on the passenger side floor under a plastic dome cover. If that's where you pulled that switch from, then maybe.

[Lingo09]

So i replaced the brakelight switch now,
But sadly i still get the warning. 
So i think it must be the pressure sensor arround the abs pump somewhere? 
Is the sensor replaceable? or does the whole abs pump need to be replaced now : (

Did you get an actual code with that fault description?
