Circuit for Brake Vacuum Pump

Featured Replies

Hi guys, 

 

My 2009 mk2 FL has the fault "17837 - Circuit for Brake Vacuum Pump- P1429 - 009 - Open Circuit" on the Engine control unit. I checked the adv. measuring blocks and found the pump off, even when applying brakes. Everything works smooth, no check lights on the dash and brake pedal isn't heavy. The fault is constant and keep showing up after clearing faults.  

 

Any ideas?

Exactly which model of Octavia do you have/engine code?

I have 2009 MK2 FL. It has 1.6 MPI engine (75 KW) which gives 105 HP I believe.
