Starter Motor Help

Todays bloody fiasco - Starter Motor packed up

Looking at EuroCarParts (amongst others) and there appears to be 2 variants so hoping someone can tell me which one I need.
As far as I can tell, the only difference is that 1 is 173mm in length (1) and 23mm length (3), the other is 135mm in length (1) and 24mm in length (3).

So which one do I need?

My car is:

2003 Z4 E85 3.0i (M54 engine I believe)

Many thanks in advance

I don’t think it makes any difference, when I swapped mine the new one was longer. Been on years without any issues.

Just replaced my starter motor with one from Eurocarparts and didnt notice that there were lucas/Bosche ones as the site pointed me towards RTX. Really cheap and it seemed ok as car started first turn of the key. However there are a number of negative reviews of RTX units but I guess if they were that bad Eurocarparts wouldnt stock them. When I got my old unit off noticed it was 'Denso' so perhaps not that good to start with.

Thanks for the info - I ordered with GSFCarparts - only because a) There was a weekend 57% off code in my email inbox which meant that b) The Bosch unit was £132 instead of like £231. Plus I get another £60 refund when I return my old one.

Will see how it goes
