Thermostat holder2. Water Pump with metal impeller3. Pulleys4. Brass bleeder screwsAnother from searching the forum5. Vanos seal?I want to be the engine at least to be in tip top condition as I do around 80km per day. Just whether any shops (MSpeed, Bav Auto) provide all these parts. Im totally not a diy person, I rather let some expert do it for me. Any workshop to recommend (MSpeed as this the shop that I found while browsing the forum)Thanks.
