These details will help.
Thanks.

Check & replace if necessary the brake pedal switch placed above pedals on the support.
If the problem still occurs you might access the ESP & ABS ECU (Electronic Control Unit) using diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC (Diagnostic Trouble Codes) memored.
Then you will be able to replace bad piece(s) and fix the problem by erasing all DTC stocked inside ESP & ABS ECU & reset it.
I'm convinced that your brake pedal switch is faulty because the glow plug warning light went ON, along with the ESP & ABS. Just replace the brake pedal switch, see if rear stop lamps light when press the brake pedal, and test the car on the road.

Can't be 100% sure but if you didn't have this problem before doing the work on the wheel bearing I can only think 1 of two things. When they removed your whhel bearing the sensor ring for the abs got damaged or the abs sensor is damaged or not pressed into place in the knuckle. The front sensors are not screwed on, they just have a little sleeve and at time with the vibrations of doing a wheel bearing they get loose. You most probally won't have an abs fault due to these problems.

unkown. that's why you need to take it to the dealer.

when the abs light or any other light flashes it means that theres a problem in that particuler system normaly on the abs system you will not feel no differance because the anti lock brake system works only if the hit the brake hard it would not allow the brake system to lock up any of the wheels thata why the name says it all ANTI LOCK BRAKE but you should get it check by a mechanic with a scanner he will tell you were is the fault good luck

dont guess !! get it plugged into a scanner and see what the code is

Try carefully topping up the brake fluid, this can happen when the level falls as the pads wear down especially when cornering

They might be two unrelated problems. I have a 2001 and have had two failures of the glowplug harness. The last time I had a constant light.

As far as the brakes go, the rear brakes are used for motion control. So if you drive it pretty hard the computer will be applying the brakes to keep traction or stability. I have had the same sensation of a soft break pedal from time to time but no real problem has poped up. I did have a master cylinder go way back when I first got the car in 2003. Have not had to replace that part again.
