I own a 328i and maybe your SA will offer me a trade for an "unreliable" 335i. Please ask him to call me as I am ready and willing.

Thanks, Mike.

Well, I tend to think that your SA was trying to convey 2 things:
1) They don't make 'em like they used to
2) the 335 family is a complicated affair.

But they are truly special.

I'd rather have a problematic DB9 than a 335i, but the again, you probably couldn't afford a DB9. And therefor, I am a better person than you.

I absolutely love my car, but after all the problems that I've had with it I don't think I'd own one out of warranty. I know others have had better luck

Just make sure the cylinder head has been replaced under warranty on this 200K mile 328. There was quite a long string of heads cast with poor-flowing oil channels. This lack of flow creates the 'tippy-tappy' after short drives.

Yes, my 328 is for sale for this reason and others.

BMW's engineering is out there on the edge of what is/can be done at the mass marketing level. My hat is off to their bravery, but I can't see owning one of these technological marvels without a factory warranty for a safety net.

I hate getting into these 328 vs. 335 discussions so I'll just respond to the original issue. Maybe the service manager was just trying to do what he thought was his part in trying to sell the guy on some kind of BMW. Perhaps there had been a discussion where someone else had mentioned the N54 and the service manager was trying to help out the CA.

If my 335 is otherwise reliable and hasn't been wrecked or anything by the time the original warranty expires, I'll keep it and never worry about the HPFP. If it fails, I'll get it fixed (BTW, anyone have a link to a BMW statement on the 100k HPFP warranty?). There's no way it makes more sense to replace the CAR than this part, even if it's out of my pocket. Anyone know what it costs to get a new one installed?

Mein Auto: 2009 328i Coupe
The 335 is a remarkable engine. You get all that extra horsepower for almost no hit on the mpg. Incredible. I think it's much smarter to go with a 335 than to buy a lesser vehicle and then mod up the horsepower. The 335 was designed from the ground up to work as a whole system, from the turbos right through the drive train. And from a purely financial point of view (although I think there's more than just this) it makes sense that they fix that hpfp problem. They'll save money if they have fewer repairs to do, even if the pumps cost more to get right. I think buying the 335 is a wise choice.

This, from a guy who really, really enjoys his MT, RWD, 328.

Call me not impressed. I was expecting more from Direct Injection.

335i Step (turbo, DI) 17/26
G37 sedan (no turbo or DI, 330HP or so) 18/26
CTS 3.6DI (no turbo, DI, 300HP runs on regular) 17/26

Now tell me how are we supposed to find it "incredible".

His point is obvious. The 335's fuel economy compares very favorably to the 328, while having GOBS more power throughout the rev range.

Speaking of which, I took a little weekend jaunt from Columbus down to Mammoth Cave KY last weekend. I was VERY impressed with our 335's power. Even up steep highway grades, when some moron would get in front of me, slowing me, then get back out of the way on the hill, I could accelerate back up to 80 without the thing even downshifting. All that power, especially down low in the revs, really is a LUXURY as well as a performance boost. I just go drive and without all the drama, I can get there at whatever rate I wish. Very nice.

BTW, caves = cool.

http://www.1addicts.com/forums/showp...64&postcount=7 - copy of what appears to be official BMW PDF on the subject. Supposedly those that 'qualify' for the extended warranty will receive a letter advising them of such.

I agree with your 2 cents.

10, 800+ miles, and no problems yet. The son's 06 325i sometimes has problems with one of his hood latches, but otherwise is going strong at 25,000 miles.(June 06 build)
I must admit that I worry a bit that the Coupe' is going to crap out on me while on a trip, and I may just go with a 328i w/ manual next time.
I have that 330i engine in my wife's X3 and its a very nice motor.

Using EPA values can be very misleading, and in this case flat out wrong. An EPA test does not reflect reality because they dont drive cars the way consumers do. Fact is the 335 has returned better gas mileage than the G37 in all tests where mileage was measured to date. When the 335 was introduced, my car was rated at 20/29, and the G37 was rated at 17/26 when it was introduced. So the politicians changed the EPA rating system, and the 335 was given 17/26 and the G37 REMAINED THE SAME. But the politicians got what they wanted, a forced reduction in the CO2 emissions without a vote on the cafe standards. If you understand the principle of direct injection, that the fuel air mixture remains stoichiometric at heavy throttle while the port injection engine runs rich to protect the engine, its a no brainer to expect that under enthusisast driving conditions the direct injection engine will have its greatest advantage. But perhaps the G will do better at continuous idle, if thats how you drive. In the motor trend test, that advantage translated to 21.7mpg for the 335i and 18.4 for your "more frugal EPA rated G37".

http://www.motortrend.com/roadtests/...335/specs.html

These 3.6,7 liter engines do not deliver the same power characteristics as the N54. A simple pressure calculation says the 335 engine is more like a 4.7L engine in power delivery, and the extra power it produces under the curve verifys that. 50-60 ft lbs more torque and 35-40 more hp all the way till 5500rpm. And we all know power under the curve is more important than peak power, especially in the real world where every drive isnt a dropped clutch drag race.

http://www.edmunds.com/insideline/do.../photoId=41802

Now that is impressive, kicks the G's backside in both dyno and real world mpg tests. Thats why international society of automotive engineers have voted the N54 "engine of the year" two years running. Perhaps you should tell them they forgot to consider the EPA gas ratings.

Nope. EPA now has been using a revised method for 1-2 years and their figures are fairly accurate.

You are right that most test show the 335i getting better gas milage than the infiniti. However starting in 2008 epa started a new way of testing cars for gas milage and all cars got lower epa number than in 2007.

The G37 get better gas milage than the G35 since it has a 7sp auto vs the 5sp on the g35 and the engine in the g37 has Variable Valve Event and Lift which is Infiniti's version of Valvetronic

Mg/Al is weaker metallurgically in all wear aspects than Al (but it is lighter). I am not sure that the new N52 is a 200K motor like the previous gen E46 I6, which was all Aluminum. I suspect the N54 will need multiple fuel pump replacements and they arent cheap, but the block is designed to be much stronger than the N52 block(N54 is an Al block with cast iron liners). For N54 longevity, the oil cooler(or better yet the dinan cooler) is probably important. Im not worried about it being turbocharged, saabs have lasted 200K+ miles routinely for more than decade. I would say that following a 15K oil change interval is not sensible, IMO, with ANY turbocharged car. Thats all marketing and politics, IMO. I have a friend with a 325 that followed the recommendations and his car eats oil compared with mine, not good. And dont believe the "oil sensor", that measures "quality", thats alot of crap too. I have the oil cooler and I change my oil at no more than 7K intervals.
+1

Find me a shred of evidence that says a turbo engine is guaranteed to fail before a NA engine... there are just too many variables involved. You know, one could argue that a turbo motor spends more time at lower RPM (I know my N54 does) so the engine is subjected to less wear and tear.

Don't buy a car for tomorrow, as you need to enjoy it today.

Dont be such a sucker for the EPA ratings, they are terrible for hybrids and for DI engines. Only an ostrich would believe that their testing is reflective of the real world, especially when its contrary to real world experiences. BMW uses them on their site because its the only "govt rating" there is and everyone compares them. Find one comparo test where the G37 has better mileage, you wont because their isnt any. Find me any G37 driver who has gotten 29 mpg(rated at 26mpg by the epa) on a 1500 mile road trip that covered a 7000 ft elevation change, I did. According to the engineering calcs DI turbos are up to 15% more efficient than port injected NA engines of the same power because the fuel delivery is much better controlled at the stoichiometric ratio under moderate to heavy throttle. Your beliefs sound like "EPA religion" to me. You believe in the EPA, I'll believe the engineering calculations, road tests, and my own gas mileage.

The 335i still gets better mileage, the EPA tests are not reflective of the real world. The G37 still gets worse mileage in the real world(its up a whopping +1mpg with the valvetronic), regardless of the EPA ratings, and its down on power under the curve so its the equivalent of a smaller engine.
