Z4 E85, 3.0i vs 3.0 si

Occasionally I get a tapping noise which I'm assuming is a HVA issue but only when the car has been stood for a few weeks. It usually clears within a couple of minutes of running the engine. When used regularly it never occurs. :thumbsup:
 
My engine is more tappity when cold, disappears when the revs drop back so I assumed it is just a characteristic of the engine & auto-choke :?

Hello forum,

I would like to hear your opinion on the 3.0i vs the 3.0 si. The HP difference is noticeable but I'm also interested in the build difference and reliability. I've heard that the 3.0si is one of the best engines that BMW built. The reason I'm asking is because it's proven difficult in finding a manual gearbox soft top 3.0 si.

Thanks a lot!

Best regards,
Alex

Hey Alex, go visit Bing & have a go in his Auto. You'd be hard pressed to find a higher spec'd car & he might even offer you a Scottish price if you bring along some 'Scottish water' to seal the deal
 
All engines are pretty reliable, as said.....so as always, go by condition/servicing done at right times and spec you want and you shouldn't go wrong with any 3.0i....imo the best all-round z4 ( if you cant justify the M's added costs) :D
