Owners Nissan Micra are often faced with the need to carry out complex repair work that requires dismantling internal body elements. Whether it's replacing a wheel bearing, repainting the interior, or installing a modern audio system, proper disassembly is a critical step. Errors at this stage can lead to damage to fragile plastic panels, loss of factory fasteners and compromised vehicle sealing.
Dismantling process Micra has its own unique features that distinguish it from other models of the Japanese concern. The design of the interior and engine compartment is designed to be compact, which creates additional difficulties when accessing fasteners. It is necessary to understand the location of hidden clips and the specifics of fastening bolts in order to avoid wasting time and nerves.
In this article we will consider in detail the algorithm of actions when disassembling various components Nissan Micra different generations. We will pay attention not only to the technical side of the issue, but also warn against typical mistakes made by beginners. The right approach will preserve the aesthetics of the interior and the integrity of all connecting elements.
Preparing tools and workspace
The success of any showdown Nissan Micra 80% depends on having the right set of tools and an organized place to work. Chaotic scattering of fasteners and the use of inappropriate screwdrivers is a direct path to broken plastic latches. You will need a set of wrenches, in particular sockets for 10, 12 and 14, as well as specialized keys for removing casings.
Be sure to have plastic spatulas ready for prying off the panels. Metal tools can leave deep scratches on soft plastic or fabric that cannot be repaired. To fix unscrewed bolts, use a magnetic mat or special trays with cells so as not to lose small parts in the carpet pile.
Don't forget about safety. Before starting work, be sure to disconnect the negative terminal of the battery. This will protect the electronic control units from short circuits, especially if you plan to remove items related to the airbag wiring.

⚠️ Caution: Never use excessive force when snapping the clips off. If the panel does not budge, check whether you forgot to unscrew the hidden bolt under the decorative plug.
Removing interior elements and door trim
Removing the door trim Nissan Micra requires special care, since the clamps here are located in several planes. You should start by removing the door handle and cup holders, if they are removable. These often hide the main mounting screws, which are easy to miss.
Use a plastic spatula to carefully pry up the bottom edge of the door card. Movements should be smooth, but confident, along the entire perimeter. You will hear the characteristic clicking sound of the clips coming out - this is normal, but if the sound changes to a crunching sound, stop immediately.
After removing the door card, disconnect the wire connectors for the speaker, lights and power windows. Pay attention to the connector latches: on Micra they often have a specific lever that must be lifted before the plug can be removed.
Removing the dashboard is a more complex process, requiring the sequential removal of all trims. Start with the center console, removing the air vents and the radio. Below them are the bolts that secure the brackets that hold the entire assembly.

☑️ Preparation for dismantling the interior
What to do if the clip breaks?
If the clip breaks, do not try to force it back. Use a plastic clamp or a specialized replacement to prevent the panel from loosening and making strange sounds while moving.
Removing the instrument panel and steering column
Removing the instrument panel from Nissan Micra often needed to replace a dashboard or repair wiring. Removing the steering column requires precautions due to the presence of an airbag. First, disconnect the battery and wait at least 10 minutes to allow the capacitors in the SRS system to discharge.
The steering wheel is removed using a special puller or by gently rocking it after unscrewing the central bolt. Do not hit the steering wheel with a hammer - this may damage the airbag coil wire, which is very expensive to replace. Make sure the steering wheel is level before disassembling.
After removing the steering wheel, remove the steering column cover. It consists of two halves connected by screws at the bottom. Carefully separate them so as not to damage the column adjustment wires. Next, remove the decorative trim around the instrument cluster.
The fastenings of the dashboard itself are often hidden under plastic plugs. After unscrewing all the bolts, carefully pull the panel towards you. Be extremely careful with the connectors on the back; they can be fragile and easily break if pulled too hard.
⚠️ Warning: When working with airbags, never point their face towards you. Store removed airbags with the pad facing up to prevent accidental deployment.

- 🔩 Use a torque wrench to tighten the steering wheel bolts
- 🔌 Take a photo of the wiring diagram for the dashboard connectors
Dismantling the engine compartment and engine
Disassembling the engine compartment Nissan Micra begins with removing the plastic protective screens and decorative trims of the engine. These elements are attached to plastic pistons, which often stick over time. Use WD-40 on the mounting areas before attempting removal.
When removing the intake manifold or receiver, be sure to plug all pipes to prevent dirt from getting inside. On Nissan Micra The throttle body often requires removal for cleaning, requiring care when disabling the electric drive.
Removing the generator and starter on some modifications can be difficult due to the dense arrangement of the components. It may be necessary to temporarily remove suspension components or the coolant expansion tank to gain access.
Pay special attention to the crankcase ventilation system. Tubes and pipes on HR series engines very fragile and can burst with the slightest force. Use heat from a hair dryer to soften old caulk if parts are stubborn.
