ZF 8HP45 Mechatronic Unit, Reprogrammed, for BMW & Audi

The mechatronic unit is the brain of the ZF 8HP45, combining the valve body, solenoids and the TCU electronics in one assembly. Failures typically show as a transmission warning message, limp mode, or harsh shifts between first and third gear.

Fitment Overview

Suits the BMW 3 Series F30, 5 Series F10 and X3 F25 with 2.0-litre engines, plus Audi applications using the equivalent 8HP variant. Software numbers vary between models, so we match each unit to your VIN.

Key Features

• Full reprogramming with a VIN-matched software file
• All solenoids, speed sensors and temperature sensor checked
• Valve body cleaned with worn sleeves replaced
• Virginized so it accepts coding to your vehicle

How We Test It

Each unit is tested on an electrical simulator that reads the resistance and response of every solenoid, followed by a pressure test of the valve body. After installation we perform TCU adaptation, reset learned values and complete a full road test.

What's Included

Complete programmed mechatronic unit, electrical connector sleeve and a printed test report.
