Read this before you buy — ECU adaptation
This is the most important paragraph on the page. A throttle body taken from another car must be adapted in the engine ECU after fitting. Without it the engine may run unevenly, hold a raised idle or log a fault.
Any workshop with a diagnostic tool does it in a few minutes. Plan it together with the installation — it is not a fault of the part, it is the standard procedure whenever a throttle body is replaced.
Will it fit your car
The number on your own throttle body decides. Check both of them: the Mercedes one and the Bosch one.
| Make | Model | Body | Engine |
|---|---|---|---|
| Mercedes-Benz | A-Class | W176 | M270 1.6 / 2.0 CGI |
| Mercedes-Benz | B-Class | W246 | M270 1.6 / 2.0 CGI |
| Mercedes-Benz | CLA | C117 / X117 | M270 1.6 / 2.0 CGI |
| Mercedes-Benz | GLA | X156 | M270 1.6 / 2.0 CGI |
| Mercedes-Benz | C-Class | W204 / W205 | M274 2.0 CGI |
| Mercedes-Benz | E-Class | W212 / W213 | M274 2.0 CGI |
| Mercedes-Benz | GLC | X253 | M274 2.0 CGI |
How to check: the numbers A 270 141 00 25 and 0280750541 are on the label and cast into the throttle body housing. If in doubt, send us a photo and your VIN — we confirm the fit before shipping.
Part numbers and cross references
| Number | What it is | Manufacturer |
|---|---|---|
| A2701410025 | Mercedes catalogue number | Mercedes-Benz |
| A 270 141 00 25 | same number, factory spacing | Mercedes-Benz |
| 270 141 00 25 | written without the A prefix | Mercedes-Benz |
| 0280750541 | throttle body manufacturer number | Bosch |
What this part does
The throttle body, also called the throttle valve housing, meters how much air the engine is allowed to draw in. The ECU sets its position electrically and a position sensor reports back how far it is actually open.
When it needs replacing
| Symptom | What to look at |
|---|---|
| Hunting or raised idle | dirty or worn throttle body |
| Jerking under light throttle | worn position potentiometer |
| Limp mode, reduced power | the ECU no longer trusts the signal |
| Engine stalls when you lift off | the flap does not return to the idle position |
| Faults P2004 to P2110 and related | the intake system group of codes |
Try cleaning before you replace. Very often the culprit is plain carbon build-up on the flap rather than a failed component. Cleaning costs a fraction of a replacement — and it also needs an adaptation afterwards.

Questions we get most often
Does it need programming? Not programming — adaptation. A workshop with a diagnostic tool does it in a few minutes after fitting. Details in the paragraph at the top of this page.
Is the gasket included? No. The flange gasket is bought separately and fitted new — an old one, once removed, tends to leak air.
My idle is hunting — is it definitely the throttle body? Rule out intake leaks and the crankcase breather first. A dirty throttle body gives exactly the same symptoms as a failed one, and it only needs cleaning.
I am not sure about the fit. Send us a photo of the label on your throttle body and your VIN — we confirm compatibility before shipping.
