Audi A4 / S4 / RS4 AdBlue problems and delete
We look at AdBlue system faults on the A4 on your driveway or in the office car park, and most visits take 60 to 90 minutes. Diagnostics are £100 + VAT, and the AdBlue delete is £330 + VAT.
How a visit for your A4 works
Registration and warning
Send both, plus the countdown mileage if the A4 is showing one.
A time and a place
Pick home or work, anywhere across Greater Manchester, Lancashire, Merseyside, Cheshire or Huddersfield.
The fault is read on the spot
Stored codes and live SCR data point to the part that has stopped working.
Talked through before we go
You get the cause, the options and the price, and any agreed work is done there and then.
About the AdBlue delete
If your A4 is a diesel with AdBlue, an "AdBlue system fault" usually comes from the pump, the tank heater, a NOx sensor or crystals blocking the injector. We don't repair any of those parts, so a repair needs an Audi dealer or SCR specialist.
The delete takes the system out of the ECU's hands and clears the countdown.
At home or at work
The A4 needs to be somewhere safe and reachable, with the keys handed over at the start.
- Your driveway, a private parking space or the road outside your home
- A work car park, as long as the site is happy for us to be there
- A residents' car park at a flat, if there's space to work round the car
Why book SGR
There's no day off to book or lift back from a dealer to arrange, as we come to the A4 and most visits are over within 90 minutes.
If the warning has only just come on, a same-day slot is often free, and our insurance covers the work to £2 million.
Reviews
Can you come out if the A4 won't restart?
Yes, that's often when people call us. Tell us exactly where the A4 has stopped, and as long as it's safe to work there, we'll come to it.
What do I need to have ready for the A4?
The keys, the registration and access to the car. Any earlier diagnostic reports are useful too, so forward them when you book.
What should I mention when I book?
The wording of the warning, the countdown mileage and how the car is used.
Can you read the A4's codes before I decide?
Yes. Diagnostics come first at £100 + VAT, and a delete is only carried out once the AdBlue system is confirmed as the cause.
Can a road-going A4 have the AdBlue delete?
No. We only delete AdBlue on A4s used off-road or heading for export, and our guide to whether an AdBlue delete is legal sets out why.
Book a visit for your A4
Tell us when and where the A4 will be parked, and we'll book a technician to meet it. Other Audi models, including the A6 and Q5, are on the Audi AdBlue page.
