whats the diameter on the holes for pdc on the rear bumper?

[klarky]

hi,

could anyone with a pre facelift rear bumper measure the diameter of one of the pdc holes for me, im looking to buy a replacement bumper as ive damaged mine, found one on ebay but it has the pdc holes, i have retro fit non bmw pdc and need to know it they will fit.

anyone help me out??

Work on 23mm

Rather a complicated roll edge on the bumper and iirc a stepped shape inside so fitment may be difficult

much appreciated! hopefully my sensors are bigger - off to get the ruler out, so i can then adjust the standard holes to fit

damn & blast, the hole for my sensor is 20mm. looks like any replacement bumper needs to be a non pdc one and ill then have to re drill the holes.
