AdBlue consumption and the EA189 emissions fix on 2.0 TDI cars
SeriousExhaust & EmissionsAuto Express's Sharan used guide states that Sharans with the 2.0 TDI have an AdBlue tank that must be topped up and can consume a litre every 500 miles, which soon adds up, and that diesel versions made from 2011 to 2015 with AdBlue systems were involved in the Volkswagen emissions scandal. Wikipedia's Sharan article confirms the model's poor UK reliability showing, recording a score of 200 points on the United Kingdom Reliability Index against an average of 100, based on a tested fleet averaging 5.3 years and 63,546 miles. Read together, the message for a used buyer is that diesel Sharans are cheap to buy but need verified emissions work and a dosing history.

- Ask for receipts showing AdBlue top-ups and long-run servicing
- Check for the emissions-fix sticker or a printed record before buying a 2011-2015 diesel
- Take it on a 20-minute run above 40mph and watch whether the DPF warning clears
