Mercedes W203 C 32 and C 55 AMG with sunroof: glass panel may separate
In August 2020, recall campaign RC2752 was issued for Mercedes W203 C 32 and C 55 AMG Sedans that had sunroofs. In these vehicles, the durability of the bonding between the sunroof glass panel and the sliding roof frame may not meet specifications and the glass panel may separate from the vehicle. If this occurred, there was an increased risk of a collision and risk of injury to road users. For the VINs of the recalled vehicles, please see PRA 2020/18467.

Engines
- For models fitted with V6 engines, the engine may run rough or hesitate due to water entering the crankshaft position sensor; if so, the sensor and wiring assembly require replacement.
Problems and faults: Mercedes W203 C 32 and C 55 AMG
- Knocking noises from the front suspension – particularly on rough roads – may be due to worn torsion bar links as water enters the ball joints through split seals.
- A whistling sound from under the bonnet when the brakes are released may be due to a faulty power brake booster.
- Tapping noises from the fuel tank may require a restrictor to be installed in the fuel vent line.
- The power steering hose may leak at the connection with the rack-and-pinion assembly due to O-ring damage.
- A scraping noise from the transmission tunnel area may be due to insulation drooping and coming into contact with the drive shaft.
- The air conditioning may stop working due to water leaking into the evaporator sensor.
- The battery in the key fob may drain – and its programming erased – if the key is left in the ignition for extended periods (up to 36 hours).
