Application and Buying Notes

Before buying, compare the part number 439838, OEM number FG18T120, and the mounting pattern details: quad leg mount, four-point fastening, 90mm mount centres, and 60mm inside mounting legs. Those measurements are the practical checks that help confirm whether the alternator will physically line up with the existing brackets and mounting points.

Also confirm the electrical setup matches your vehicle. This unit is a 12V alternator with 180A charge current, internal regulator, 6 groove pulley, and pin code IR228. If the vehicle uses a different pulley style, regulator arrangement, or connection layout, the alternator may not be suitable even if the shape appears similar.

The listed weight is 7.67kg, which can be useful when handling, comparing replacement options, or checking against the removed unit. The note that there is no connector for revolution counter is also important, as the charging system and any related signal requirements should be checked against the original application before installation.

If you are replacing a failed alternator, it is worth checking the belt condition, pulley alignment, and charging system connections at the same time. A correctly matched alternator still depends on the rest of the charging system being in sound condition, including the belt drive, mounting hardware, and battery state.

This Valeo unit is identified as a leading OE manufacturer and supplier for many euro vehicles, but that does not replace the need to verify the exact application. Use the part number, OEM number, voltage, amperage, mount style, and pulley details together rather than relying on the badge alone.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 439838 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include VOLKSWAGEN TOUAREG, VOLKSWAGEN TOUAREG 2011, VOLKSWAGEN TOUAREG 2012, VOLKSWAGEN TOUAREG 2013. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part number 439838, OEM number FG18T120, the 12V 180A specification, quad leg four-point mounting, and the 6 groove pulley details against the original alternator and vehicle application before purchase.
