Before jumping in and doing the job yourself, why not phone a dealer (or 2) and get prices for doing the job ?

I think you'll find you'll need to pay someone to turn off the warning light, unless you've the means to do it yourself.

If you search the VW/Ford/SEAT forums you may find a way of doing it.

The SEAT web site links to a video explaining how to fill it up so I guess they think it is OK to do it yourself.

Sorry - that vid just says take it to the dealer!

My AdBlue warning came on at almost exactly 22,000 miles.

The car has a comprehensive service plan from the SEAT dealer that seems to cover everything (oil, filters, pollen filters, brakes, discs, wipers, you name it..) ... everything except AdBlue.

They quoted £68 to do a top up. Problem is my SEAT dealer is ~50miles away and there is a trade off between laziness and wasting an afternoon driving up to them.

I therefore checked (and double checked) with the dealer that it was OK to top it up myself. Both the receptionist and workshop manager assured me that it was no problem and would not affect the SEAT warranty or the dealer service plan. (and all my mobile calls are recorded ;-) )

I opted to use genuine VAG products, bought from my local VW dealer, 3 miles away.

In terms of the top up, you have two choices.

• Either you can buy 7 or 8 small bottles (1.89 litres) that have the proper screw in connectors. These cost £6.73 each.
• Or you can buy a 10 litre keg and a proper filler hose (VAG part number 000-012-499). The small bottles were £6.73. The 10 litre keg was £13.03 and the filler hose was £8.51.

I was surprised how cheap the VW dealer was. Tesco sell 1.5L of Adblue for £7.50, Amazon sell the 10L kegs for £19.99 and EuroCarParts were looking £32.99 for a 10L keg. I assume all VW dealers have the same pricing right across the UK and at these prices it makes sense to use the own brand product and keep the receipts in case there was ever a dispute down the line.

I opted for 2 of the kegs and the proper hose. It was a completely painless exercise. No Spills, no mess. Using the proper hose means you won't overfill it. The actual filling process only took about 5 minutes. The car was showing "Refill in 800 miles" at the time and it took 15 litres to completely fill it. You have to put in at least 10 litres to allow the warning message to be reset. To remove the dashboard warning message, simply turn the key to the "ignition on" position, leave it for 30 seconds (I waited 60 seconds) and then turn the key the rest of the way to start the engine.

All prices include VAT were correct as of yesterday - 19-March-2016.

Hope this helps ....
