Before you buy a used Smart roadster (452).
Taken only from Testigo's sourced sheets. Use it to question the seller and on the test drive: it does not confirm that any particular car is affected.

The essentials.
- 1 documented, sourced fault for its engine.
- That is not much data: if no other faults show up here, it does not mean it has none.
- It only applies with certain equipment or production dates: ask what this car has.
- We have no official recalls on record for this model; ask anyway, with the chassis number (VIN).
Typical faults by engine
The period and mileage are those mentioned by each sheet's sources. They are not a maintenance interval and do not predict that any particular car will fail.

- Roadster 452: water leaksBody / sealing
- Period mentioned
- 2003 guide and MY2003–2005 supplement.
- Mileage mentioned
- The sheet does not mention a mileage.
Applies if: Only Roadster/Roadster-coupé 452 MY2003–2005 with water ingress confirmed by a rain test. Service guide of 01/09/2003 and smart gmbh supplement of 09/06/2005; check whether an MY2003/04 car was converted to the MY2005 seal system. Drops that the drain removes without damage are not the defined fault.
Official recalls: ask before you pay
We have no official recalls on record for this model. Our list is not complete: ask anyway, with the chassis number.
- Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
- Ask an official Smart dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
- Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.
