Thread: Water in fuel

Well after continuous water in fuel messages but draining it didn’t show any water, I tried disconnecting the bottom sensor. The next day I got the same error which said to me that it wasn’t that and that breaking the circuit didn’t help. As I still couldn’t ease out the entire assembly for complete replacement I managed to switch out the sensor on the assembly itself. I noted the slightly different design for the sensor but it still fit. Hoping that that will be the end of the error. I suspect the error is about a faulty sensor not that it’s detected water in fuel as it never says on the display “water in fuel”, just restricted performance (yellow triangle). Dunno. Will report back.

I had to have my radiator bottle replaced, tried the sensor 1st to no avail, so my mech got an after market one $50 less than OE, but it is OE spec from MEYLE automotive spare parts - MEYLE who seem to be a good company, even make some parts better than OE spec.

Found a better link Online catalogue - MEYLE

Two weeks on and no water in fuel errors since. For my dear that’s nearly conclusive. So for those who can’t be bothered manoeuvring the entire assembly out, the sensor on the top of the assembly can be swapped (relatively) easily.

Had a bit of an attempt at doing this on mine last weekend without success...could not get the complete assembly out...how did you move the housing enough to remove the sensor from the top of the assembly? more specifically to remove the torx screw holding it on? Do you have to disconnect the fuel lines to the assembly to make more wiggle room...

Might be a job to hand over the mechanic as access is awkward even with a set of ramps!

Cheers

Just reviving an old thread as this happened to me on a recent Pilbara trip that included many deep water crossings. Got a Water in Fuel error mid crossing, which doesn't help the stress levels, and went into Restricted Performance. Got through ok. Got the Gap tool out to check for codes and it got stuck half way through "loading files" which it then promptly aborted because it had no internet. It refused to load so could not get any info from it. Cheesed off about that. Once internet was found GAP loaded ok. I sinced cleared the faul and can't remember it exactly. Anyway thought that the error was because the sensor got wet and not water in fuel so left it over night to dry out and the next day all was good and no trouble since then. So the question is how to stop the sensor getting wet (or triggering for some other reason) and going into Restricted Performance for no real reason. Has any one some novel solutions?

You don’t need Internet to use the gap tool however if it’s out of date and app/ firmware updated, it will want to download changes. Worth checking its working with internet before you head out. It’s pretty rare that this happens. Did you recently update the firmware?

no I didn't and that's the surprise. I've been using it on and off for a few months, never updating it via the PC so it never occurred to me that it might try an update when I'm out in the bush

Found out today, during a fuel filter replacement, why I got the "Water if Fuel" error. There was no sensor wire attached so the connector got wet! Will be having words with my Indie as to why they did not connect the sensor wire when they replaced the fuel filter housing. Very ****ed off given it caused a restricted performance during a water crossing.
