Well engine back together and at cold start I am having misfire issues. It seems the oil pressure is leaking out of the BMW VANOS Camshaft Sprockets and takes time to build up pressure.

Once the engine is warm and oil pressure restored to the camshaft sprockets the VANOS timing is working as it should be and confirmed through engine diagnostics.

I asked the workshop what needs to be done to fix this and they said new BMW VANOS Camshaft Sprockets.

I've now ordered 2 new BMW VANOS Camshaft Sprockets (intake and exhaust). Genuine BMW units are flapping expensive, FCPeuro has them for US $619 each (here in Australia over $2000 for both).

Screw that.

So I found an OEM manufacturer called Aisin in Japan (25% owned by Toyota) who make them and found them online at https://spareto.com/

Wow SUPER impressed by Spareto.com!

Parts in stock, good prices (I paid only Aus $615 for the parts) and shipping
EXTREMELY fast and great prices. Shipping was Aus $58 to have the parts expressed shipped via DHL to Australia.

I also ordered a new set of wiper blades and purchased Valeo Compact Wiper Blade Set C6055 which cost Aus $32.60 while here is Aus these are Aus $62.25

IMPRESSIVE!

So from ordering online to having the parts at home took only 5 days.

I suggest trying Spareto.com for parts in the future.

So I can drive my car currently and it operates properly once warm, I just need to allow oil pressure to build up so the timing can work properly.

Back into the shop soon for the new VANOS Camshaft Sprockets.
