This car still has the first edition of the HPFP!! She babies this car and it ONLY gets Esso 93/98 or Shell V100. To date we have had absolutely ZERO issues with the HPFP.
As result, I think this issue has much more to do with fuel type and quality as compared to just faulty parts. I am amazed to see people spend $50K+ on a vehicle, then shop around and put the lowest price (or cheapest) gas in it. The other cited possibility is the high sulfur content in US fuel.
In the end you get what you pay for.. (Crap in, crap out..)
My experience .. and my .02
The N54 is a great motor and has TONs of unrealized performance.  |
I have a 2009 Z4 35i as well. No problems yet but the car is just over 5,000 miles. The original pump did not fail but was replaced in Feb 2011 with the recall (at about 3,500 miles). Always use Shell gas too! Hope the new 1m doesn't start having this issue. That would be pitiful if BMW hasn't gotten this issue right yet.
