Peirburg water pump differences, vibration dampers.?

[Meds]

Hey guys..

I see AutoDoc have 2 compatible versions. One with 'vibration dampers' and one without.
The vibration damped version is over £100 cheaper.
Both say compatible with : BMW Z4 Coupe (E86) 3.0 si, Year of Construction 04.2006 - 08.2008, 2996 , 265 PS
And include the OE number of 11517586925 in the descriptions.

With:

Without:

Any ideas? I'd obviously like to save £100 if I can but obviously not if it's the wrong part.
Thanks for your help.

Just looked it up and I bought the cheaper one for my 2.5 (AFAIK it's the same pump for the 3.0) so I wouldn't worry.

Good to know. I thought they would be identical but I've ordered one these 3 times now and never noticed the 2 versions before.
Thanks smorris_12.
I'll get it ordered.

Update, the pump with the vibration dampers is working a charm, as expected.
