Second Hand Mercedes-Benz CLA Starter Motor

Yes, all petrol and diesel variants of the CLA have a conventional starter motor — it is used to crank the engine on start-up on every engine option offered in the CLA range. The only exception worth knowing is that some CLA variants equipped with Mercedes' stop-start system use a reinforced or higher-rated starter, so the spec of the unit can vary even within the same engine family. If your CLA is a hybrid or plug-in hybrid variant, confirm with the breaker whether the starting system differs, as some electrified layouts use an integrated starter-generator rather than a separate conventional starter motor.

The C117 and W117 are actually Mercedes' own internal designations for the same first-generation CLA, covering the original 2013 launch through to the facelift in 2016 and on to the second generation arriving in 2019 — so buyers will often see both codes used interchangeably for what is commonly called the CLA Mk1. Fitment within the first generation is primarily driven by engine code rather than the model year, so a starter from the same engine code should be a strong candidate whether it's pre- or post-facelift. However, there were production changes across the 2016 facelift period that may affect ancillary fittings and mounting details, so confirm against your registration with the breaker before purchasing.

Yes, the badge matters here only because it points to a different engine — the CLA 200, 220, and 250 all use different engine codes, and the starter motor is sized and configured to match the specific engine rather than the badge itself. The most useful thing you can do is supply your engine code, which you can find on your V5C or via a VIN check, rather than relying on the badge alone. A breaker will match the starter to your engine code, giving you far more confidence in fitment than the number on the boot lid.

Trim level makes no difference to starter motor fitment on the CLA — SE, Sport, AMG Line, and Edition trim designations are about interior, exterior styling, and equipment, not the engine or drivetrain. What matters is your engine code and gearbox type (manual or automatic), since these are the mechanical variables that determine which starter motor was fitted. Tell the breaker your engine code and transmission type and ignore the trim badge entirely when sourcing this part.

The second-generation CLA launched in 2019 on an entirely new platform with revised engine options, so a straight swap from a Mk1 to a Mk2 starter motor is unlikely to be correct even if the engine size looks similar on paper. Engine codes changed significantly between generations, and the starter motor is matched to the engine code above all else. You should treat these as two separate vehicles and confirm the engine code with your breaker to make sure you are quoting on the right unit for your generation.

Gearbox type can affect starter motor fitment on the CLA because the mounting position and nose configuration of the starter sometimes differs between manual and automatic transmissions due to the different bellhousing geometry. Always tell the breaker whether your car is a manual or one of Mercedes' 7G-DCT or 8G-DCT automatic transmissions, alongside your engine code. Giving the breaker your full registration or VIN is the safest way to ensure they pull the correct unit from a matching vehicle.
