Please see images from hood label & service manual below. Note that all of the R134a weight specifications are DIFFERENT. Which is correct?
Hood label:
In German, R134a specification is 460 +/- 10 g [Conversion from grams to pounds or ounces: 1.01 lbs or 16.2 oz]
In English, R134a specification is 0.91 +/- 0.02 lbs [Conversion from pounds to grams or ounces: 413 g or 14.6 oz]
Service manual:
R134a specification is 490 +/- 10 g [Conversion from grams to ounces or pounds: 17.3 oz or 1.08 lbs]
R134a specification is 15.8 +/- 0.4 oz [Conversion from ounces to pounds or grams: 0.99 lbs or 448 g]
Here's the label on my 2010 LCI with 534 (automatic air conditioning).
PS: This is not the first time I come across data in the Bentley manual which is apparently either wrong or does not cover all production variations of the series (e.g. torque values).

Thank you, that's extremely helpful information! I wonder if all USA MINI LCI hood labels have the same R134a weight conversion error present on my hood label.
To other members: Please post a picture of your MINI hood label showing the required R134a weights in grams & lbs.
This is the sticker i have on my original hood. 2012 R58 JCW with the N14 engine. https://www.ecstuning.com/b-genuine-...n/64506916084/ Thats the part number in the bottom right hand corner
But my sticker says Fullmenge 460 +- 10g so at one point they updated it to 415. Picture was in 2014 time stamp.
Hope that helps.
Very interesting and helpful.
For the label shown in your picture, the R134a weight in grams and lbs matches (correct conversion), unlike my label.
Does your sticker with Fullmenge 460 +- 10g show the correct conversion to lbs (1.01 +/- 0.02 lbs) or the incorrect conversion (0.91 +/- 0.02 lbs) like mine?
Haha...incorrect conversion just like mine. Thank you!
I would assume that there are some DIYers and shop techs who were misled by the label error and improperly filled MINI A/C systems with the incorrect weight of R134a.
Please correct me if I'm wrong. In North America, we're currently not absolutely certain which R134a label is correct, your original label or the updated label.
In your update 2012 label, the R134a weights in grams & lbs match (415 g equals 0.91 lbs).
In your original label and my 2012 original label, the R134a weights in grams & lbs do NOT match (460 g does not equal 0.91 lbs)
In George's German 2010 label, the R134a weights in grams & lbs match (460 g equals 1.01 lbs)
Is the proper R134a charge in North America 415 g or 460 g? Do you see what I mean?
With no information on this whatsoever, my gut feeling (and almost 3 decades of living here) tells me that there is absolutely no way a BMW built Mini has any dimension, weight, volume or any other measurement engineered/measured/specified (and subsequently documented) in imperial rather than metric. Hence my 2 cents worth bet goes for whatever metric value is printed on any label, irrespective of whether any non-metric conversion value also printed on it matches the metric or not.
The scientific community worldwide is completely metric, and I would hope that the same is true for engineers. Imperial units are archaic and serve only to confuse.
However, based on ESCTuning's input, the metric weights were incorrect and the imperial weights were correct on the original hood labels in North America. Who would have thunk?
