I also had this issue. Take rear wiper off and try clear nozzle with pin or paper clip. In my case I had to replace the plastic nozzle. Fairly inexpensive easy fix (assuming you washer pump is working)

I have a 2017 B9 avant (190bhp 2.0tdi) 2WD with the 7speed DSG. Car is on 124k miles and gearbox has never skipped a beat. Gearbox has had all its regular gearbox oil changes though when due, so would at least look for that in the service history, and a timing belt depending on age/mileage. On thing to note is these cars suffer from adblue fault, where it throws up the EML and requires sorting. You will see regular threads including mine. Not sure if this was rectified with the facelifts but worse case scenario you need a new adblue tank system which is pricey. Not sure how common it is in reality as out of the thousands of these cars on the roads even the 50-100 threads online isn’t much in comparison but definitely something to look out for in the service history if it’s been replaced. I have really enjoyed the A4 though and has been very reliable for the most part. The 2.0tdi 190 isn’t really fast, but not slow either and good compromise for economy.

Hello, As per above, my 2017 A4 2.0tdi has the dreaded adblue fault. This has been an intermittent that usually cleared on its own but now seems to be a hard fault and down to last 100 miles before ‘no restart’. I know this topic is very tedious with many posts on the web, but looking to gather my thoughts and ask few questions in my quest to fault find this error. To my knowledge it can either be; 1) Stuck adblue tank float/level sensor 2) Faulty adblue pump 3) Faulty control module (possible corrosion) 4) adblue injector clogged/broken 5) low/weak car battery *not seen much on this but have seen mentioned. So far I have checked the injector looked very clean but nothing was passing through it when engine on,I then pulled the adblue line to injector, and again no adblue being pumped. Should be noted that my car battery is definitely on its way out to point stop/start not working and stuttering to start at times. So this is suggesting a potential control module or pump fault. The question i have is would the pumping system be inhibited if level sensor is potentially stuck at empty or low level? Like a pump protection of sorts? And thus low pressure. And also, has anyone successfully fitted a used/second hand adblue control module to their car? Feel free to add any other checks I should carry out. Car is on 124k miles and full service history by Audi. Got a baby on way so was going to be very soon parting ways with car, so reluctant to just fling £1200+ at full new adblue tank/pump system if it can be avoided. If I find any solutions in the meantime time I will post update on here. Thanks
