After searching for the best deal, I discovered that Autodoc is the only place selling a proper replacement unit. Instead of the factory Mercedes part A 210 540 0072, I replaced it with a Meyle 014 830 0010—a high-quality alternative at a fraction of the cost. After installing the new unit, I took the SLK 230 for a test drive to confirm that the problem was fully resolved. Success! The car now runs perfectly again. But that’s not all—in this episode, I also share project updates on some of my other cars: 🚗 VW Transporter T3 – What’s next for my classic van? 🚗 Triumph 2000 – More work needed after the barn find. 🚗 Ford Escort Mk3 – The latest progress on this legendary build.
