Application and Buying Notes

Before ordering, confirm the vehicle uses Bosch part number 0125711153 and that the existing alternator matches the 12V, 150A rating. The mounting style is listed as double pivot lever, so the physical bracket arrangement needs to match the vehicle installation.

Also check the pulley setup carefully. This unit is supplied with a free-wheel belt pulley and 6 grooves, and Bosch notes it as an alternator type excl. vacuum pump. Those points are important if the original alternator has a different drive arrangement or if the engine uses a vacuum pump integrated elsewhere.

Bosch recommends additional repairs of the V-belt or V-ribbed belt. If the belt shows wear, glazing, cracking, or stretch, it is sensible to inspect or replace it at the same time so the charging system is not let down by a worn drive belt.

The unit weighs 7.330kg and is packaged at 24 x 18.5 x 20, which can be useful when handling freight or comparing against the removed part. Manufactured in Spain and backed by a 12 month warranty, it is still essential to verify the application details against the vehicle before purchase.

Fitment data supplied for this alternator includes Audi A4, Audi A4 Allroad, Audi A5, and Audi Q5 references. That makes the part relevant to a defined Audi application range, but the final check should always be the exact part number, pulley count, mounting style, and vehicle build details.

If you are cross-checking a replacement, compare the old unit’s label, pulley, and mounting points rather than relying on appearance alone. Alternators can look similar while differing in output, pulley style, or bracket fit, so matching the verified details is the safest approach.

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 0125711153 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.
