Hi

I have just bought a 2.0 TDI A6 Avant. It's the first car I've had with Adblue and wanted to know a few things about it....if you could assist me, please? My mechanic has topped it off as part of the pre-sale service. I read that it should last about 8-9 thousand miles on t'internet, but I was wondering what other people's experience are of the longevity of Adblue in terms of how long it lasts, and would it be best to just top it up during the year (monthly/quarterly), or wait until it's close to the 8-9 thousand miles and fill it up then? Also, is there any particular brand of Adblue that I should use? Finally (again on t'internet) it says you can disable Adblue and just drive on diesel alone....but I take it this is a bad idea for multiple reasons (emissions, mileage consumption etc)?

Thanks again for your help in advance.

Hi I would personally wait until the light came on, it gives you 1500 miles warning, with regard to the brand of Adblue you wont get better than Halfords own brand, its made by a company called Yara who produce the most pure Adblue in Europe, finally I can thoroughly recommend the Forte additive as this stops it crystallising in the system and blocking it all.

Hi Steve

Thanks for that. I didn't know it needed/best to have an additive with the Adblue. I'll take a look and see where it's available and add it whenever I get it.

Thanks for tip about the Forte Steve. I’ll get some of that for a family member’s non-Audi. One 150ml bottle be enough? 
 
Many thanks and kind regards,

Gareth.
