Wipers and headlights operating after a parked car has been locked can be difficult to capture in the workshop. The delay and the order of events are useful parts of the fault report.
What the forum discussion does and does not show
An MHH Auto thread describes a 2006 Peugeot 307 with these symptoms after several controllers had already been changed. A reply suggested investigating vehicle-network wiring from experience with similar cars. The visible discussion does not provide a confirmed repair of the original vehicle. It is a topic for investigation, not evidence that a particular wire or module is faulty on your car. Read the original discussion.
Why the sequence matters
A report saying “the BSI is bad” loses detail that could help reproduce the problem. Describe what happens between switching off, removing the key, locking and the first unexpected operation. Do not assume every Peugeot uses the same network layout, connector positions or wire colours. Those details must come from information for the actual vehicle.
Capture the event without dismantling the car
- Record a short video from a safe position showing the delay and the affected functions.
- Note whether the event follows rain, washing, battery work or a long parked period.
- List every module replaced, with its identity and the result of each change.
- Supply a full vehicle scan, including modules that cannot be reached.
- Mention aftermarket alarms, radios or other electrical additions.
If the inspecting garage has captured power-supply or communication measurements during the event, include those records. A scan taken while everything works may tell a different story from one recorded during the fault. AXION can review the history and discuss an investigation; we will not prescribe another BSI solely from the behaviour described in an online thread.
AXION supports owners and independent garages with body-electronics and network fault enquiries. Send your existing report through our repair enquiry form, or call 07440 134303. We will confirm whether the vehicle is needed at our Didcot workshop or whether a removed module is suitable for UK postal assessment.
