Are you having problems with your BMW 318i? Let our team of motoring experts keep you up to date with all of the latest BMW 318i issues & faults. We have gathered all of the most frequently asked questions and problems relating to the BMW 318i in one spot to help you decide if it's a smart buy.
BMW's F30-series 318i is claimed to average 5.4-litres of fuel consumed per-100km, measured on a combined cycle of city and highway driving. This is quite efficient for a large four-door car.
So long as it is serviced on time and looked after well, the BMW 318i can be a great, reliable and enjoyable mode of transport. Although it is no tar-burning supercar the 318i has been known for 30 years as a well-made, pleasant way to get around town. Older second-hand models should have a professional inspection before purchase to make sure they have been serviced regularly and not driven without car, as this can affect the car's long-term reliability.
Trade it in on an M140 or one of BMW's many performance-oriented models.
While you can theoretically make a 318i faster, you're wasting money - and potentially making your car illegal to drive on the road - when there are faster models available from BMW.
While they've grown physically larger over the last 35 years, BMW's 3-series has been an excellent mid-size car and continues to be. While they aren't cheap they can be optioned from basic transport to luxury runabout, though servicing costs through BMW dealers can be expensive compared to Japanese rivals.
It is paramount to service them on time and look after them by driving sensibly.
The official combined cycle fuel economy of BMW's 318i is 5.4L/100km.
There is a cooling-off period in Victoria. You have three clear business days from the time you sign the contract of sale to change your mind, but you automatically lose that right if you accept delivery of the car within that period. By taking it home your wife forfeited the right to the cooling-off period.
My best advice to you is to not buy an old used BMW; they will only soak up whatever money you might have saved up. An ageing BMW with high mileage is a money pit; it will cost plenty to service and keep on the road, whether you use a dealer, which I would not recommend, or an independent mechanic. Buy a well-respected Japanese brand, such as a Toyota Corolla, Mitsubishi Lancer, or Mazda 3.
If you've checked the battery and that's ok, check the starter to make sure there's no problem with that, and then pressure check for a blown head gasket. It's not unknown for a head gasket to blow on the 318 and you can get an hydraulic lock in a cylinder that will make it difficult to start if that cylinder is the one that's on compression when you go to start it. It doesn't always show up on the temperature gauge as overheating, but it is sometimes evident with white smoke from the tailpipe when the engine is cold.
Yes, you can, as long as you can open the door using the key it should be ok. It's wise to tell the buyer about the situation so they know and there's not likely to be any comeback. I'd be tempted to fix it before you sell it; it's likely to be easier to sell without the locking problem.
