There are numerous alarming accounts regarding AdBlue, stemming from individuals who primarily undertake short journeys as well as those who go on longer excursions.

However, I pondered the number of vehicles equipped with AdBlue that have experienced no issues related to AdBlue.


Have you encountered any troubles linked to AdBlue throughout your ownership? For example, nitrogen oxide sensors, AdBlue reservoir replacement, etc.

I understand that the situation is not straightforward (it relies on factors such as the duration of ownership, annual mileage, year of manufacture, etc.), but it would be intriguing to obtain a general estimate.

My husband has owned his CLS220d shooting brake for one and a half years. He has completed little over 11,000 miles, primarily consisting of short journeys (20-mile round trips) and a European road trip. No issues whatsoever, and one tank has been replenished.

OP, it would be prudent to specify that this poll is exclusively for individuals who are currently operating or have previously operated a Mercedes Benz vehicle equipped with AdBlue.

No issues encountered; I have completed 20,000 miles primarily on lengthy trips, merely replenishing fluids periodically.

In my experience, Adblue issues typically arise after approximately 35,000 miles or more. Consequently, individuals without any issues may possess vehicles with reduced mileage.

We possess a 2017 AdBlue C-Class for five years. No issues.

Individuals typically engage in posting or commenting solely after encountering an issue, so the overwhelming majority of proprietors continue to drive contentedly.

Individuals frequently join this thread to seek counsel on AdBlue issues, subsequently disposing of their vehicles and not returning to the forum.

This poll is problematic since it appears you acquired it when it was three years old, and we lack information regarding its mileage or any replacements made before to your acquisition, as well as the current mileage since your purchase.
Individuals who report no issues with Adblue are merely postponing inevitable problems unless the defective software and components have been rectified.

The poll would be more effective if it included the car's year and mileage. May exhibit a pattern.


Purchased a 2017 E350 for $11,000 and sold it for $28,000. No problems.

Purchased a 2018/19 GLC 350 for $29,000 and sold it for $42,000. No problems.
