Volvo C30 T5 Fuse Blowing

stew91 · Nov 8th, 2017, 11:37

Hello,
I have been having problems with fuse #33 which is 20amp blowing on my C30. It throws up an engine management light for the bank 1 lambda sensor but also last night for the first time brake failure came up on the dash and all the dials stopped working including the indicators. Once I stopped and pulled the key out the ignition and started the car again it was back to normal with just the engine management light on. Any help with solving this would be great.
Thanks
Stewart

Was it a certain fuse that kept blowing or multipul fuses where was the damage on the loom?

Hello,
Just a follow up on this in case anyone else has the same problem it ended up being the brake vacuum pump that had burnt out (it is on the passenger front side of the engine bay part number 30793023) replaced it with a second hand one and has been fine ever since.
