However, there was criticism of the M52 engine in some markets, especially the UK, which had high levels of sulfur in the petrol during the late 90's. Sulfur acts as a corrosive agent against Nikasil and led to a lot of the early engines having premature bore-liner wear. Fortunately this problem was solved in post-September 1998 cars with the introduction of steel cylinder liners, with the designation M52 TU-3. '"Over the years, BMW has provided replacements with steel, cast-iron or Alusil lined engines, at considerable cost to the manufacturer. Often, disgruntled owners have borne the brunt of these replacement costs, and prospective buyers are at risk, too."</blockquote>
