I need advice

I Gang! Yes, I am new to this forum. I don't currently own a diesel BMW but I could use some advice on buying an X3 diesel. My wife currently drives a '14 X3 2.8i. We like how it drives and it has served us well. Our biggest gripes are the depreciation (we are still under water on the loan vs value after 2years), frequent check engine lights (it goes on and off on its own. When it doesn't go off we take it in and usually costs us $50 thanks to the extended warranty), and it never delivering on its fuel economy ratings
(rated at 28mpg, but it has seldom gone above 25). We want something with better fuel economy and better reliability. I have suggested an X3 2.8d. Nice used examples can be found below $30K. I am no stranger to diesel having previously owned two Jetta TDI's (one I bought new and has over 300K miles). Soooo, are the X3 diesels reliable or would I just be trading one set of headaches for another? What are the pitfalls (other than depreciation)?

The 28dís seem to be solid.
Before purchasing any used bmw Iíd want the maintenance and repair history. If too many trip to dealer for repairs itís a red flag. Iíd also scan for codes with a scanner that is specific to bmw to make thereís nothing lurking.

On the gas mileage thing, it will vary based on speeds, traffic patterns, and weight of right foot. If youíre in a state where gas is around $2 a gallon the savings on fuel will be minimal. Further, if youíre under water on the current car, are going to trade it in a wholesale value, then purchase the new one at retail then what youíre proposing seems to be a poor move financially.

Thanks! I have my eye on a 2016 that is CPO so service history should be easy to get. I haven't seen anything newer than that (last year for them?) so I don't know that buying new is an option (I live in the U.S.). In my experience, dealers have more room to bargain when they are selling a used car so I might be able to get them to to at least pay off my trade so I don't have to rollover any but that might be wishful thinking. Where I live diesel and 87 octane gasoline are running about the same but I run 93 or 94 which runs considerably higher. Switching to diesel makes even more economic sense from that standpoint. Your advice is greatly appreciated!

The X3 is heavy with a big coefficient of drag (area). In some respects the 2 liter diesel is a bit under-powered in it, leading to heavy use of the throttle to get moving. You won't get great mileage around town (should be adequate at least), but should do much better on the road. Fuelly.com shows average is 31, around 10 mpg better than the X3 average for all engines: http://www.fuelly.com/car/bmw/x3?eng...=&submodel_id=

Consumer Reports has consistently rated the X3 as the best of the "luxury" small SUV's. I've been a few (dealership shuttles) and they seem pretty nice.

Not to start any flame wars, but does a diesel 3-series station wagon work better? Much better mileage. Most people don't really need an SUV; of course you're coming from another X3, so ...

Thanks for joining the thread! I wish I could talk my wife into a 3-series wagon with the diesel. I love the thought of something with the utility of an SUV that drives/handles like a sport sedan. Unfortunately, She does not like the idea of driving a wagon. I tried to point out that SUV's are really just lifted wagons but she won't budge. We commute about 130 miles round trip which is why we would like having something that gets better mileage than our 2.8i. Thanks for your thoughts!

I haven't heard anything bad reliability-wise about the X3 28d. Unlike the cars, the X3 has an ATC 45L transfer case, which to my knowledge hasn't seen the same failure modes as the Pre-LCI ATC 35Ls. The HPFP vulnerability is still there, however being a former TDI owner you should know about using quality fuel already.

That can be fixed with a KermaTDI tune . Highly recommended.
