Description
Electric motor for sunroof (sliding roof) and sunshade for Peugeot 308 T7
High-quality Bosch electric motor designed for the sunroof drive and interior sunshade on Peugeot 308 T7 models. This replacement sunroof actuator ensures smooth opening, closing and sunshade operation, restoring proper function when the original unit becomes noisy, slow or unresponsive. Ideal for professional workshops and experienced DIY mechanics searching by product code (0390200075 / 8401RR) or part number to quickly identify the right component.
Technical Information
Manufacturer: Bosch
Model: Peugeot 308 T7
Product Codes: 0390200075, 390200075, 8401RR
Other Numbers: 0390200075 8401RR
Fitment And Compatibility
Designed to fit Peugeot 308 T7 sunroof assemblies. This motor typically replaces the factory unit when the sunroof glass or interior sunshade becomes difficult to move or the drive produces grinding noises. Always match the product codes listed above with the part you remove to confirm fitment.
Function
The unit drives the sunroof mechanism and the interior sunshade, converting electrical input into rotary motion that is transmitted via gears or cables to move the glass panel and shade. It provides regulated torque for smooth operation and often contains an internal gearset, motor armature, brushes and an electrical connector for the vehicle harness.
Typical Failure Modes And Causes
Common reasons for sunroof motor failure include wear of internal brushes and commutator, stripped or broken gears, water ingress leading to corrosion, seized bearings, and cable or regulator failure within the sunroof mechanism. Symptoms include slow movement, intermittent operation, grinding or clicking noises, or complete lack of motion. Heavy use, age, and poor drainage of the sunroof channel accelerate wear and failure.
Replacement Procedure (Overview)
Recommended for experienced technicians or competent DIYers. Typical replacement steps:
- Disconnect the vehicle battery before starting work to avoid short circuits and unintended operation.
- Remove interior trim and partially lower or remove the headliner to access the sunroof housing.
- Locate and disconnect the electrical connector from the motor.
- Unbolt the motor from its mounting points and remove it from the mechanism.
- Inspect the drive cables, guides and sunroof drainage for additional damage or blockages and replace if needed.
- Install the replacement motor, secure mounting bolts to the manufacturer’s torque specifications, reconnect the electrical connector and reassemble the headliner and trim.
- Reconnect the battery and test full operation of the sunroof and sunshade, checking for smooth travel and correct end-stop positions.
Installation Recommendations
Always follow manufacturer service procedures when available. Ensure sunroof tracks and drainage channels are clear of debris before installation. Check and, if necessary, lubricate moving parts with the correct type of lubricant specified for sunroof mechanisms. Verify the electrical connector is clean and making good contact. If the mechanism uses adjustable end stops or calibration, perform alignment procedures so the sunroof seals correctly and does not bind.
Why The Part Most Often Fails
Failure most commonly results from mechanical wear (worn brushes, gears or bearings) and water ingress that corrodes internal components. Blocked drainage or misaligned guides increase load on the motor, causing overheating and premature failure. Regular maintenance of drains and track lubrication extends service life.
