Does anybody know if there is any particular feature in the 550i V8 to address the water pipe seal degradation problem?
I understand that the improved engine cooling should alleviate the problem somewhat. Anybody aware of something else besides that?

No I didn't hear anything like this, only I know is I asked foramen shop at Sterling BMW VA and he said those engine has been address this issue so it should be a problem even so he saw one or two 7-series (750) with this problem.

I have 63k miles now and so far I haven't had any engine/coolant related problems yet.
Leak Diagnosis Pump (also called DMTL pump) was replaced at around 47k.

1. Changed Valve Gasket Covers ($700)
2. Changed Timing Chain Covers (Did it because I was already doing valve covers) ($150)
3. Changed Belt Tension er ($100)
4. Installed a new transmission pan and replaced the Transmission Fluid ($250)
5. Cracked bushing in front lower control arm. Changed the whole front end. ($950)
6. New strut mounts ($200)
7. ST Coilovers ($1200)
8. Rebuild Vacuum Pump ($120)
All this was done @ 60k. I had a horrible engine leak. My valve covers were in pretty bad shape. The Timing chain covers were starting to go bad as well. Glad I changed those while my mechanic was pretty much there. I didn't need the whole front end for my car. I just got a real good deal on the whole Meyle HD kit for my car, and figured what the heck and did it anyway. My bearings on my mounts were bad so I changed them after I had my coils installed. Everything That I have listed has been done in the past 30 days. it has cost me a lot more than I was planning on spending in a month.
