Multiple systems not working after going through big puddle.

[zebby42]

Hi, I have a 2020 t6. I recently went through a big puddle very fast and I started getting warnings on the dash and radio screen. The warnings are:-
parking aid unavailable, start/ stop not working and an oil sensor which put on the engine management light. My question is, is there one fuse that would possibly feeds all these systems that might have been shorted out by the water getting where it shouldn't have and also it has affected my tracker as well, which I don't know where it is or how it's wired up.
Any help would be much appreciated thank you.

I had a similar experience a couple of weeks ago, hit some standing water at a relatively low speed and straight away oil sensor warning light and engine light on. Basically the engine undertray was pulled down ( the one covering the adblue and fuel tank) and vw in their infinite wisdom clips the oil sensor wire harness to it so it ripped the connector apart, pulling 3 wires out of the connector. I resoldered them together ( brown to brown, a white wire with a blue trace to one the same and the other 2 wires back together). Warning went away but had to clear the engine code ( carista for me) and all good. Make sure you clip the harness to the body and not back to the undercover so if it happens again it's just the undercover that gets damaged. The undercover was repaired and refitted so lucky escape. Good luck and hopefully a free fix

Exactly what happened to me, its likely to have damaged the wiring to the oil sensor. Repair this and replace the fuse - sorry, can't remember which, it was years ago now. Its not a hard job if you're OK with some basic electrical work, just awkward doing it on your back under the van.

Thanks for all your help guy's, with a bit of luck I can get it sorted now.

Good luck, follow the harness up to where it enters the vehicle, mine had popped out the rubber grommet, just pushed back in. Saves water and noise getting into the cabin

Thanks again for all your help, it turned out to be just 1 10amp fuse

Annoying but possibly the cheapest and lowest hassle fix

That's great news, glad you got it sorted
