hello, when i was rebuilding my turbo i accidentally snapped a a piece of plastic pipe off the 4x4 sensor i took it off the vehicle fixed the pipe and refitted, the light stopped flashing all good or so i thought, after a week the 4x4 light started flashing again,my question could i have put pipes on wrong way round and it took a little while to show up
thanks matthew

maybe

I would think the only reason that it would take a while to show up is that you are losing vacuum

Must have a vacuum leak from your fix mate

i will have to have a closer inspection, is the system dealing with much pressure as they are just push fit, also just to add that air did come out of one of the push on plastic covers when i blew into my repaired pipe, also abs light comes on intermittently

its just low pressure vacume

i thought so as pipes are push on

yes as it vac they get sucked on anyway

Was your abs ok before you done the repair

While playing around with the vac pipes you may have disturbed the rust on the vac tank and caused another leak , my intermittent abs light was a rotten wire in the plug on the osf wheel sensor , only found it by accident while doing the alternator

hi ollie no abs problems before repair, i will have to wait for snow to clear and have a look underneath for loose pipes etc, would it narrow fault down if i said the light stops flashing if i put it in 4x4 high and low box

The light should stay on with 4x4 engaged goes off when in 2wheel drive it's a big can of worms I renewed all my vac pipes solenoid tank etc light still flashes so I got used to it hope that helps

Your abs sounds a bit of a coincidence

im hoping i may have put pipes on wrong way round i only had two i wasn't sure about so will try that first

Have this issue. Narrowed it down to the 4x4 solenoids. The solenoid pipes are colour coded blue and yellow by a dotted line on that pipe. There is also a dot on the solenoids, funnily enough 1 blue and 1 yellow! I Crawled under the truck and pulled the bellows of the front axle actuator and checked it moved freely. It did so I connected a bit of hose to the where the yellow pipe goes (nearest centre of vehicle) and sucked and the actuator moved, also had wife in cab and she told me the light stopped flashing when I did this. Then pulled pipes off solenoids and felt for suction, a latex glove was good for this as suction isn't that great. This showed me the blue pipe was sucking but the yellow wasn't.
