BMW 3 Series GT F34 mods: what is worth fitting first

Sequential LED Mirror Indicators for BMW F20, F30, F31, F34, F36, F87, E84

Most F34 owners start with mirror caps, LED lighting and a fix for the worn trim inside, then add CarPlay if they plan to keep the car. At the time of writing, interior LED kits start from around €9, mirror caps from around €43, LED fog lights from around €67 and a wireless CarPlay module from around €247.

First, check what you have

The F34 is the 3 Series Gran Turismo, built from 2013 to 2020. It is a five door hatchback with a longer body than the F30 saloon and F31 Touring, so it shares a lot with them inside and at the front, but not at the back. If you are not sure of your chassis code, see how to find your BMW chassis code.

The facelift (LCI) arrived in 2016. It changed the lights and some interior details, and that matters for a few parts on this page, such as the cup holder light, which comes in separate pre-LCI and LCI versions. Around the changeover, go by what is on the car, not the registration date. More in LCI vs pre-LCI explained.

The bumper question matters less on this car, because we do not currently stock front lips, diffusers, side skirts or tailgate spoilers for the F34. Fog lights are the one area where M Sport and standard bumpers can differ, so check the housing shape before ordering. Everything we list for this car is in the 3 Series GT F34 collection.

Many of the parts below are shared across the F20, F30, F32 and related models, and their titles only name a few of them. Where it matters, check the fitment table on the product page rather than assuming a part fits every F34.

Mirrors and grille

Mirror caps are the usual first change because they need no paint and are quick to swap. The gloss black mirror caps replace the original painted caps. The mirror cover overlays come in black, white or carbon look and sit over the original caps instead. Carbon look is a printed finish, not real carbon fibre. Replacement caps unclip once the mirror glass is out; overlays are bonded on with tape, so clean the cap well first.

The sequential LED mirror indicators replace the indicator strip in the mirror housing with one that sweeps outwards. Fitting also means taking the mirror glass out, so it is worth doing at the same time as the caps. Sequential indicators are not accepted everywhere, so check local rules.

At the front, the kidney grille colour strips clip onto the slats of the existing grille to add a stripe of colour. They do not replace the grille, and they suit cars that keep the original slats.

Lighting

The cheapest visible change is the LED interior light kit, which swaps the yellowish cabin bulbs for white ones. Check which bulbs your car uses first, since some lights may already be LED.

For the fog lights there are two routes. The LED fog light units replace the whole lamp and ship from our EU warehouse. The angel eye fog lights add a ring light around the lamp. Both mean working under the front bumper, usually through the wheel arch liner, and unplugging the old unit. Compare the plug and housing in the photos with your own before ordering.

Inside, the cup holder light is a small job that gets noticed every night. Pick the right version: the pre-LCI cup holder light for cars before the facelift, or the LCI cup holder light for later cars.

Worn interior fixes

The F34 cabin wears in the same places as the F30, and each has a cheap fix.

Fitting is a trim tool job: lever the old part out gently, unplug it if it has a connector, and press the new one in. Covers that bond on need a clean, grease free surface. Our view: do these before any exterior styling, because you touch them every time you drive.

Screens and CarPlay

The wireless CarPlay and Android Auto module keeps your original screen and adds CarPlay as an extra input, controlled with the iDrive knob. The 10.25 inch wireless CarPlay screen replaces the factory display with a larger touchscreen and keeps the original iDrive system underneath.

Before ordering either, find out which iDrive system the car has (CIC, NBT or NBT EVO) and the size of the current screen, because the wiring differs. Fitting means removing the screen and some dash trim and routing a loom behind it. A careful owner can do it in an afternoon. Our CarPlay module or screen comparison goes into the choice in more detail.

Where to start

For a first-time owner on a budget:

  1. Fix what is worn inside: door pulls, window switches, gear panel.
  2. Swap the interior bulbs for LED and fit the cup holder light for your version.
  3. Change the mirror caps, and fit the sequential indicators at the same time if you want them.
  4. Add grille strips and LED fog lights.
  5. Finish with CarPlay if you plan to keep the car.

A few of these parts ship from our EU warehouse and usually arrive in about 4 to 8 working days within the EU. Others ship from Asia and take longer. See our fit guarantee before ordering. If you are weighing up parts shared with the saloon, our F30 and F31 buying guide covers that side of the range.

FAQ

Do F30 parts fit the F34 Gran Turismo?

Many interior parts, mirror caps and fog lights are shared, which is why so many listings name the F30. The body behind the front doors is different, so F30 boot spoilers, diffusers and rear bumper parts do not fit. Always check the fitment table on the product page.

How do I know if my F34 is an LCI?

The facelift arrived in 2016, so later cars are LCI. Around the changeover, look at the lights and the build date on the car rather than the registration date.

Can I add Apple CarPlay to an F34 without replacing the screen?

Yes. A CarPlay module connects behind the factory display and shows CarPlay or Android Auto on the original screen. Order the version that matches your iDrive system and screen size.

Why do you not stock lips or spoilers for the F34?

The Gran Turismo body has its own bumpers and tailgate, so parts made for the saloon do not fit. We do not have F34 specific styling parts of that kind yet, and we would rather say so than list something that will not fit.
