Brake pad sensor - how far can you go with it on?

They're cheap and can be considered a consumable when doing the pads.

As for the U-codes present, the severity of them depends of whether they are from the high-speed or low-speed CANBUS. Your intermittent faults look like they are high-speed and likely directly related to the P-code (any fuelling issues freak out and shut down the TDV6 engine module causing the cascading U-codes - it seems intentional in order to save the HPFP from seeing any air/water..), while the historic are low-speed (not important as they won't stop you).

Thanks for the follow up.

No changes as we’ve been “Bush” for a few days and not been in decent phone range till arrival today in Darwin.

I’m more inclined to get it looked at in Cairns, dealership here wasn’t that helpful last time - ended up going to Alice and then Adelaide which only fixed half the issue.

Obviously a bit of country to cover before then and a bit more remote through the Gulf.

Think I can live with the sensor light, the underlying reason for the brake wear to be triggered early perhaps something more to get looked at here - depends how serious?

Given no issues past 2,000k’s.

the sensor says , "hey , check your break pads"...then you can make an informed decision when to change them.

This is a similar issue that’s come up?

I’m not techy enough to know off hand where the fuel filter is located. We did hit some big puddles on Charlotte Plains station if that’s the water the code on my vehicle is highlighting or the post mud wash down a few days later.

Food for thought would be very lost without the forum insights. Today is Picnic Day in the NT nothing open.

Depending on what other insights there is we’ll crack towards the Gulf or just do a quick Kakadu loop later this week if an appointment can be got at a garage or the Darwin dealer.

Cheers all!

That’s what we did, ordered parts booked a slot but guys at Mt Isa said they looked alright at the time but I said fit anyhow given the time we’d be on the road, full vehicle etc.

Rotors had done 55,000 and pads 18,000 and mileage on both city driving so my pad and tyre wear has been higher than others usually for wear items.

Unfortunately this wasn’t done at a main dealer ie limited diagnosis and advice on the codes.

I had a quick check with my iCar and the codes are not showing but the pad sensor light is. At least it’s a yellow and not a red light.

Error codes are not raised because the pad sensor lights up.

If you have the sensor light on the dash showing and you have checked the sensor head itself is undamaged (ie not open circuit due to wear) then you have an open circuit somewhere else in one or the other of the sensor wires. Check the sensor wire's connections.

Yeah okay I see, I need a thread on the other P fault then. I’ve not check the newly fitted sensor or had the front sensor from June checked yet.

If it's not going into restricted performance mode then the fuelling issues aren't serious and probably don't warrant any worry. If it does give you further trouble (restricted performance/go-slow mode), the fuel filter is located underneath the drivers seat, mounted on the inside of the chassis rail - you'll need to remove the underbody plastic guard backwards from the x-member to get access (not difficult). Check the connector and wires coming from the bottom of the filter for damage, and then the water tap-off valve thing is the little yellow thing sticking out from the bottom. I have not needed to do this myself, but believe you unscrew this little yellow know a turn or two with the ignition on (fuel pump running), but engine off. A bit of detail here but, perhaps useful to know before you head-out over the next few days by the sound of it.. I suspect if you take it somewhere to get looked out they will likely change the fuel filter for you as 'remedy' for this fault.

As for the brakes, this is obviously completely unrelated to the above. I would still be looking at the wear sensor wires, new or not. One end is connected to one of the pads through the calliper body, the other inside the wheel arch (tricky to get to). You've got new pads so just remove wires at one or both ends to get rid of light - or just go on as you are as it's a non-issue as you have seen.

Good luck with the remainder of the trip!

Thanks mate appreciate the details in case a bush repair is needed to check the filter. We’re going to continue on into Kakadu, so far so good.

All these little “issues” are one for a skilled independent to check through at home should they not be obvious. At least I know the braking materials are fresh :-) and happy to have missed the border closures to date.
