<DIV></DIV>&gt;Could someone please tell me the VW part number for the correct Autobahn
<DIV></DIV>&gt;antifreeze to use. My local VW dealer said to use Prestone.
<DIV></DIV>&gt;I have been using Sierra as it says that its Phosphate free.

<DIV>Though Sierra may be phosphate free, it is propylene glycol based, not ethylene, as has VW recommended. </DIV>
<DIV>If you study the labels you will see that the Orange Dex-Cool or&nbsp; Orange Extended life&nbsp; anti-freeze labels state the formula is ethylene glycol based&nbsp;which&nbsp;doesn't contain&nbsp; phosphates, silicates, bromides or amines. </DIV>
<DIV>The green propylene glycol based antifreeze Sierra may be safe for animals and perhaps the environment-but the engine? If it is phosphate free, the label did'nt say phosphate free or I missed seeing it.</DIV>
<DIV>So far what I have learned from the list and others , the Orange stuff is safe to use as a replacement for the Blue stuff. The type is most critical for the WBX. </DIV>

<DIV>I have been using the Prestone orange extended-life for 3 years now with no problems. </DIV>
<DIV>I have seen it in the new VW's at the dealership. </DIV>
<DIV>Does anyone know if the color represents the presence or absence of phosphates, amines, bromides ,silicates,propylene or etheylene glycol? </DIV>
<DIV>I am inclined to think this is a&nbsp;universal color coding &nbsp;like those used for fuels like stove oil and Diesel, etc. </DIV>
