2008 SULEV 128i concerns
Have been consiering a used 2008 128i convertible available locally with low miles and very clean. One item that's concerned me is that it's an SULEV version with the N51 engine (vehicle was sold new in CA).
I've done quite a bit of reading on this and have been unable to conclusively determine answers to the following:
1) Fuel pump integral with tank - I've seen this stated a number of places, but then again countered elsewhere. Checking RealOEM.com it appears the pump is separately available from the tank. Having to replace a fuel pump I can accept - it's mechanical, it can fail - but generally I consider the fuel tank to last as long as the vehicle (barring unusual circumstances). Having to replace the tank because the pump has failed, because the pump is integral to the tank, is a significant disadvantage. So, what's the situation on this - pump integral with tank or not?
2) The N51 has a number of additional emissions related components compared to the N52 and some components that are more expensive (e.g. stainless steel vs the standard material), meaning there is additional potential cost for repair as time goes on. Countering this is the extended warranty I keep hearing mentioned that applies to the SULEV emissions system. A potentially big gotcha in this regard is if the additional warranty applies to the vehicle where ever it may be, as with other warranties, or only within CARB states - and I am not in one. So, does the additional emissions warranty apply where ever the vehicle may be or is it limited to repair within a CARB state?
Thanks in advance to anyone who definatively clarify these issues.
