Card, pressure sensors, front suspension, turbo and clutch on the Laguna IIKnown weak points
- Engine / equipment
- Renault Laguna II (petrol and dCi)
- Period mentioned
- 2001–2007
- Symptoms
- The car will not open or start (card, reader or start button); false tyre-pressure warnings; front-axle play; on diesels, turbo failure; a clutch that wears out before 50,000 km; rust on load-bearing parts.
- Possible cause described
- The hands-free card is its biggest weak point. Front-axle parts (links, ball joints, arms and bushes) are under-engineered. Auto Bild mentions an undersized clutch that may need replacing before 50,000 km (about €950).
- Check for the garage
- Test the card and start-up several times; check play and rust; on diesels, check for turbo whistle and smoke.
- Cost cited in the source
- No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

Applies if: The Laguna II uses the same hands-free card; the German guide calls it its biggest weak point.
“Card not detected”: the car does not recognise the key cardElectrical and electronic systems
- Engine / equipment
- Hands-free card and cabin unit (UCH)
- Period mentioned
- Approx. 2003–2009
- Symptoms
- The cards stop opening or starting the car, hands-free and with the buttons, and “Card not detected” appears; sometimes it clears by itself after a few minutes.
- Possible cause described
- Owner reports: the cabin unit (UCH) stops recognising the cards’ code; described as common on the Scénic II and Mégane II.
- Check for the garage
- Try the other card and its battery; at the dealer or with a diagnostic tool, check the UCH and relearn both cards.
- Cost cited in the source
- No verified estimate; relearning the cards is usually a short garage job.A rough figure from the original database, not an up-to-date quote.
