According to MB EPC, for the C32, the 113 141 0125 has been replaced by 112 141 0325. 112 141 0125 was never used on a C32.

Confirmed, 112 141 0325 is the one on my car, the newest revision.

Brilliant, Thank you for this.

My pleasure! If you do replace the TB, make sure to get all the seals/hoses where it plops down onto the supercharger (?) opening lined and/or hooked up properly, or else you'll risk some nasty surging.

Thanking you: also do you know if it is the 113 141 0325 (E55 throttle body) that is plug and play for the 32 ?

Somehow I don't have a listing for 113 141 0325. I see that the 211.076 (E55) used 113 141 0625.

Yes, I cant find it listed either, the MB parts websites display the same p/n (1131410625) however there are several listings (ebay) with the 1131410325 claiming to be W211 TB's.
e.g.
http://www.ebay.com/itm/MERCEDES-W211-E55-AMG-OEM-THROTTLE-BODY-1131410325-/161090690536?pt=Motors_Car_Truck_Parts_Accessories&hash=item2581c0dde8&vxp=mtr
Hopefully someone will chime in with the p/n of the 74mm compatable alternate throttle body for the 32.

For my woes (p0120) am waiting for the cable as it is definately electrical (no leaks etc) and star also points to P0120 Code - M16/6r1 - (Throttle valve actual value potentiometer) so will see how it pans out. Ref; https://mbworld.org/forums/c32-amg-c...y-p0120-3.html

Why not just get 1131410125? It's 74mm. Or just go to the 80mm TB.

Oh man,
I was under the impression the 1131410125 was 64 or 68mm.
Thanks for clearing that up.

Lenin / Mac - apologies to dig up this old thread but I just had my throttle body actuator go out and had a couple questions.

the indy MB shop i took it to replaced the malfunctioning throttle body with a used one he had in the shop which he said was the same part number = A 113 141 01 25 and consistent with the original. a new one was $1200 and this used one he sold me for $150 so hard to pass up.

any idea if part number "A 113 141 01 25" on this used throttle body is truly the same as the original throttle body actuator? i read somewhere that this one is a Bosch and doesnt have the AMG logo on it but is the same but not sure. since i didnt get the old throttle body back i cannot verify.

my concern and reason for asking is if the size of the throttle body with this used replacement is the same as the original stock one????? would not want a smaller one since i have some mods.

the good news is this shop (Hi-Line Automotive in Downers Grove, IL...did a great job) fixed it in a few hours and was back on the road and all seems back to normal. i'm glad its fine, but still surprising as when it went into limp mode as this part failed it created a horrible rough idle and could not drive above 10 mph with a couple strange codes that didnt indicate throttle body failure (codes were p0120 throttle/pedal position sensor/switch "a" circuit and also p0105 manifold absolute pressure/barometric pressuure circuit, plus ABS malfunction)

appreciate any input thx for the help

A1131410125 is the original part for M112.960 and M112.961 engines (SLK32 and C32). But it was also used on variety of M113 engines (E55 as an example) and a bunch of M272 engines. The M272 engines are a non-AMG type and that is most likely where your TB without the AMG markings came from. As long as this TB is in working order, your should be fine.

Lenin really appreciate the feedback. good to know that that P/N was used on other non-AMG model so hopefully easier to obtain if ever fails again.

so far this TB is working just fine and seems like the response when pressing the accelerator is a bit better more responsive than the old throtle body...not sure if the old one had a bunch of build up on it as i never cleaned it before, but so far so good with this one !

thx man
