Ok mate borrowed car and called later, suspension inactive and dc fail and wont do any speed. Got there seemed like dc selected so tried switch and on off but brakes seemed full on hard pedal?
Scan and cleared cambus fault tried again same. Battery reset suspension raises then dc fault and wheels lock. Any ideas?

Following morning went back started up warmed up touched brake pedal normal so into D and drove home normally! Friend in total shock what how when? His parting comments. Fickle these FFRRs like a fit bird,look lovely on the arm but can do much drama. Anyhow I drove her home and she put her lippy and high heels back on! lol.

Never a dull moment with a FFRR.

Doom its back!
All fine then ding bong on comes all warning. HDC AIR SUSPENSION ABS LIGHT ON.
Then the brake pedal is solid on and car does not want to move!
So far IID came up Can bus fault and front lh abs sensor changed it and still no joy. Any suggestions please?

Clear all down and remains same..... Help got CAR OWNER VIRUS!

When I've had an ABS sensor on the blink on a L322, it feels like the brakes are applied and the car wants to stop all on it's own. Can't recall the peddle being hard though?? It can be driven if enough throttle applied.

If it is an ABS fault, then electrically it could either be:
* The sensor itself (which I know you've changed)
* Break in the wiring back to the ABS module in the engine bay
* The BMW ABS module itself which are known to fail due to heat damage

The fault can be mechanical also, either:
* Play in front wheel bearing
* Rusty / broken stator ring. Try blowing it out through the ABS sensor hole with an air-line.

My first thoughts when you said the peddle was hard, was a collapsed flexi-hose keeping pressure on one caliper (i.e. allowing fluid into the caliper, but not out again).

Whenever I lend anything to a “mate” I normally tell them “If you break it you buy it” as they leave the driveway.....😉

Still ongoing and the fault keeps happening, staying local as its my spare FF!
I have changed ABS speed sensors bled brakes often but is unsafe as this happens randomly. What is consistent is an ABS Fault 'Pressure sensor offset' on IID.

Anybody had this fault and where is the sensor appertaining to it? Also have seen some reported historical issues with YAW Sensor. Emailed GAP and he says that YAW sensor does not exist?
Confused to say the least!  Help got CAR OWNER VIRUS!

Maybe take the abs module off and find a place that can test it mate. Not sure what they charge but I remember wheeler dealers doing that and only got charged £250 all be it 10 year ago

Think I dare say it was the YAW Sensor and despite Gap telling me it doesn't have one! I found one on Ebay and an article suggested a fault in 2003-2004 that causes the above fault. After finding it (rear of centre console bolted to the floor, plug is facing rear floor carpet)
Changed it and fingers crossed after 30 odd mile today it has not reappeared.  Help got CAR OWNER VIRUS!

Connector pins to the ABS module, n/s above the wing.

Had this on my TD6, exactly the same. Waited 2 hours to have it flatbed 'ed back from just down the road once, by the time they arrived it had sorted itself out

Also ended up replacing the master cyclinder.

Brilliant result, never knew that the yaw sensor could do that.

Hopefully you've got this cracked
