Easy Repairs You Can Do on Your Own BMW

Having a BMW is awesome, but it can be costly to maintain if you take it to the shop or the dealership. Luckily, there are plenty of easy repairs you can do on your own. If you’re not sure where to start, here are a few things you can do in your own garage or driveway to keep your BMW running smoothly.

First, Have Somewhere to Work

The first thing you need to do is make sure you have somewhere to safely work on your car. If you have an attached garage, that will be ideal, but if you’re like most of us, your garage is probably a catch-all for everything you don’t have space for in the rest of your home. Before you get started working on your car, take some time to sort through your junk and organize your garage. Not only does this give you somewhere to keep your car while you’re working, but it also makes your work area safer and less cluttered, too.

Change Your Oil

Changing your oil is one of the most straightforward repairs you can do — and it can save you a lot of money in the long run. You need:

  • Fresh oil – Check your owner’s manual for the correct oil.
  • A new oil filter.
  • Tools – A wrench or socket to remove the drain plug and an oil filter wrench.
  • An oil catch pan for your old oil.

Jack the car up and place it on jack stands. Never work under a car that’s only up on a jack. Locate the oil pan and position your catch basin under it. Remove the drain plug and let the old oil drain out. Set the old oil aside and replace the drain plug.

Use the oil filter wrench and loosen the old oil filter. Remove and discard it. Put a little bit of fresh oil on the gasket on your new oil filter and screw it into place — not too tight, though. You don’t want to use the filter wrench to tighten it. Then, refill your oil to manufacturer’s specs, check for leaks and you’re done.

Replace Your Drive Belt

A broken drive belt can leave you stranded. For cars that use serpentine belts, it runs your alternator, your power steering, your air conditioner and your water pump. Replacing them is simple, though. You’ll need:

  • A replacement belt.
  • Tools – A socket wrench with a long handle or breaker bar.
  • Belt map – Usually located on a sticker under your hood or in your owner’s manual

Remove the broken drive belt. Study your belt map and locate all of your pullies. Thread the belt through the pullies as detailed on the belt map until you reach the belt tensioner. Use your socket wrench and breaker bar to pull the belt tensioner back until you can place the belt over the tensioner, then slowly release it to place tension on the belt. Done!

Replace Your Battery

This can be a little trickier, depending on where your battery is located. Some BMWs have their batteries in the trunk or under the back seat. The only difference between these and batteries under the hood, though, is that these have a vent that needs to be placed correctly.

You will need:

  • A replacement battery.
  • Tools – Open-ended wrenches or sockets.
  • A car memory keeper

First, plug in your memory keeper. This helps to keep a charge in your car’s systems to prevent problems with the engine’s computer — as a bonus, it also keeps you from losing your pre-set radio stations! It isn’t required for all cars, but it is recommended.

Once you’ve located your battery, remove your terminals — negative first, then positive. Then loosen and remove your battery hold-down. Finally, remove the battery itself, replace it with the new battery and reattach your terminals in reverse order. Unplug the memory keeper, and you’re good to go.

Taking care of your BMW is easy if you have the right tools and plenty of space to work. Take some time to organize your garage and pick up a few tools, and you’ll be turning wrenches in no time.
