Renault Clio: UCH/BCM Body Control Module Failure

UCH/BCM Body Control Module Failure is a common electrical fault on the Renault Clio on the 2005–2019 cars, and we rate it major. Putting it right costs $300 to $1,300 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 15 documented faults on the Renault Clio.

What you are looking at

No photograph available

We do not hold a verified photograph for this fault yet. We would rather show none than show a picture of something else.

What goes wrong

The Renault UCH (Unite Centrale Habitacle) body control module manages the immobilizer, central locking, power windows, lighting, dashboard functions, and wipers. Failure is triggered by voltage spikes during jump-starting, water ingress into the module housing, or age-related capacitor degradation. Symptoms span multiple unrelated systems simultaneously. Replacement requires specialist programming and pairing to the vehicle's immobilizer system — an off-the-shelf swap does not work.

What you would notice

No-start condition with all dashboard warning lights on simultaneously
Central locking and windows failing at the same time
Multiple unrelated fault codes across different systems
Intermittent complete electrical shutdown

How to check it

Where to look. Under dashboard, typically in passenger footwell area

Inspect the passenger footwell for moisture evidence.
Test all windows, locking, and the immobilizer by starting the car normally.
If a workshop inspection is possible: Perform a full multi-system diagnostic scan and check whether fault codes span unrelated modules (ABS, airbag, instrument cluster, UCH) simultaneously — this pattern indicates BCM failure rather than individual component faults.

What it costs to put right

$300 to $1,300 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has the car ever had unexplained electrical faults or refused to start?”
“Has the BCM or UCH module been replaced or reprogrammed?”

Now check the Renault Clio you are actually looking at

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today. That comes from the official records for that plate. Enter the plate for the free details, or get the full history and a market valuation from $13.49.

Where this comes from

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.

Renault Clio buyer questions

Is uch/bcm body control module failure serious on a Renault Clio?

We rate it major and common on the Renault Clio. The Renault UCH (Unite Centrale Habitacle) body control module manages the immobilizer, central locking, power windows, lighting, dashboard functions, and wipers. Failure is triggered by voltage spikes during jump-starting, water ingress into the module housing, or age-related capacitor degradation. Symptoms span multiple unrelated systems simultaneously. Replacement requires specialist programming and pairing to the vehicle's immobilizer system — an off-the-shelf swap does not work.

How much does it cost to fix on a Renault Clio?

$300 to $1,300 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Renault Clio years are affected?

Our research records this fault on the 2005–2019 Renault Clio. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.

How do I check for it before I buy?

Inspect the passenger footwell for moisture evidence. Test all windows, locking, and the immobilizer by starting the car normally. If a workshop inspection is possible: Perform a full multi-system diagnostic scan and check whether fault codes span unrelated modules (ABS, airbag, instrument cluster, UCH) simultaneously — this pattern indicates BCM failure rather than individual component faults.
