VW Transporter T5 (2004-2009) Body Control Module

VW Transporter T5 Body Control Module Repair

Hazard lights switching themselves on, the horn sounding along with the indicators and front wipers that stop working properly are the Transporter T5 faults most often traced to its body control module. In a working van the BCM runs the lights, wipers, locking and other body functions, and a failing one can even shut down while the van is on the move — if that happens, have it looked at promptly. The BCM is removed by your garage and posted to us, and we repair the T5’s own unit and return it ready to refit.

T5 BCM Faults We Repair

• Front wipers not working correctly
• Hazards coming on by themselves
• Horn sounding when the indicators are used
• BCM shutting down while driving
• Locking or lighting faults on a hard-working van

Not Sure It’s the BCM?

Check the wiring under the driver’s seat, which T5 owners often point to when chasing electrical faults, along with the fuses and the battery’s condition and charging voltage. Water getting into connectors is another common cause. Our guide to how a body control module works explains the unit’s role; then describe the van’s symptoms on the repair form, or contact us.
