Hi all

 

Just had the Error: AdBlue (DEF). start possible in 650 miles come up. Topped up adblue and still the same. Going to book it in later. Got a feeling its could be the NOx sensor as all seem to be related. Have tried the rest procedure st the same.

Any thoughts on what it could be.

Thanks.

Guess time:- Have you driven the car since refilling as that may reset the errors?

Yes have done over 50 miles.

I suspect your idea about the N0x sensor is correct as that was exactly what was happening when mine went.
It wasn't cheap!!

I had the Bank 2 O²  sensor go my 1.2tsi Yeti a month ago, that was £100 to get a Meat & Doria one. I think the NOx sensors are around £300 but change the same with a 22mm lambda sensor socket.

I'd be interested in your fault code. I got 17143 Bank 1 Sensor 2. Sensor 2 being the after catalyst one. It was easy enough to access from under the car. With the new O² sensor the fault immediately cleared.

So what fault code do you have ?

Update.

Got car back from garage this morning. They dismantle the AdBlue tank cleaned pump and all sensors and filled, all working now and show correct miles left
