Yeti 2017 Dash lights on - warnings and fix!

[Zednine]

Presented with a lot of warning lights the other day in the middle of a short trip - ABS, Brake, Power steering, TCS, ESC, AFS!

I have a vagcom Hex Interface and was able to scan for faults. Came back immediatly after reset. I thought that it may be the battery as odd stuff can happen if battery is low. After much reasearch I was inclined to check the rear left wheel speed sensor - All looked fine - Easy to reach just behind wheel. Sprayed the heck out of it with some liquid maintenance and waited a while. Took it for test drive and all warning lights are now out.

Thanks too all the web sites and utube info I was able to fix it myself and will be able to replace the sensor.

New sensor ordered - Ebay.

Hope this helps someone

Very interesting.  I've got an intermittent tyre pressure warning light, on the Yeti, that will sometimes allow it to be reset on the button and at other times won't.  No fault codes present when it's scanned,

[Zednine]

I'd check tyre pressures, you may be resetting the tyre to a low pressure and just telling car that it is ok. Its the difference in trye rotation that triggers alert.

Don't buy cheapo sensors, they can be problematic, I speak from experience, well known named items are the way to go, they are about double the price of cheapo sensors!

[J.R.]

I have fitted a cheapo Chinese ABS sensor to replace the OE one that failed, it was less than €2 so I bought a few, it has been fine so far.

 

The OE ones were way more expensive.

you must have been lucky, the cheapos i bought had very different internal resistances to the bosch one i fitted and it worked!

Sorry Schtum, Just checking.. 😉
