Module Programming

Coding, programming & module replacement.

A replacement module isn't fixed until it's coded to the car. Pro Tech adapts, codes, and programs control modules on Audi, Volkswagen, BMW, and Mercedes — including Audi/VW component protection — with OEM parts, at independent-shop pricing, without the dealer visit.

    VIN

    A swapped module has to be adapted to the vehicle it's going into. Every module we install gets coded and configured to your VIN — features enabled, swap faults cleared.

  • Modules, sourced + installed

    OEM

    Headlight modules, comfort and body modules, clusters — we source the OEM unit, install it, and program it. One shop, one invoice.

    Coding, programming, and Audi/VW component protection handled in our bay — typically well below dealer pricing, on an independent shop's calendar.

What we program

The electronics side, by brand.

Our Repairs page covers the mechanical side of European service. This page is the electronics side — replacement and retrofit control modules adapted, coded, and programmed so the car accepts them. Pick your platform.

VW Group · coding + component protection

VW Group runs the tightest gate in the business: component protection locks infotainment units, instrument clusters, and other modules to the original car. We code and program replacement modules, clear component protection, and handle the adaptation the module needs to actually work.

What “component protection” means — explained below.

Typical jobs

  • Component protection clearance on replacement modules
  • Headlight and adaptive-headlight module replacement + coding
  • Comfort and body control module adaptation
  • Instrument cluster and infotainment swaps
  • Module-swap fault clearing and feature enabling

Timing chains, water pumps, carbon cleaning — that's the mechanical side. European service, on the Repairs page

Komponentenschutz

What is component protection?

Component protection is VW Group's anti-theft lockdown. Infotainment units, instrument clusters, and certain other modules are married to the vehicle they shipped in. Swap one in from a donor car — or install a brand-new unit — and it stays restricted until it's cleared through factory-level online authorization.

That clearance is normally a dealer-only visit, which is why a perfectly good replacement module ends up sitting in the dash showing an error instead of working. Pro Tech handles component protection clearance on replacement modules for Audi and Volkswagen — so the part you paid for actually works, without the trip to the dealer.

Module stuck in component protection? Bring it in.

Sound familiar?

  • Radio or nav screen reads “Component protection active”
  • Infotainment powers on, but features stay locked out
  • Instrument cluster was swapped and warnings won't clear
  • Module replaced at another shop, still throwing faults
  • Used OEM part from a donor car won't fully activate

01

Confirm

We verify the module, its part number, and your VIN — the clearance has to match the exact unit in the exact car.

02

Authorize

Factory-level online clearance releases the module to your vehicle. This is the step that's normally dealer-only.

03

Verify

Functions tested, faults cleared, codes rescanned. The module works like it shipped in the car.

Component protection is an Audi / Volkswagen (VW Group) system. BMW and Mercedes lock modules differently — that's coding and programming work, and we handle it too.

The dealer alternative

Same OEM module. Different invoice.

Dealers do this work every day — at dealer rates, on a dealer calendar. Here's how the same job runs at an independent shop that can code it.

The quote

Dealer service department

Often written as a full-assembly replacement, at dealership labor rates.

Pro Tech

The failed module, the labor, and the coding — itemized in writing before work starts. Typically well below the dealer number.

Parts

Dealer service department

OEM, from the factory catalog.

Pro Tech

OEM, from the same catalog — new, or used where a used unit is viable and we can clear it for your car.

Scheduling

Dealer service department

Booked through a service advisor, often days to weeks out.

Pro Tech

An independent shop's calendar. We tell you when we can take the car — and the answer is usually sooner.

Who does the work

Dealer service department

Whoever's on the rotation that day; you rarely meet them.

Pro Tech

The same technicians who do our European mechanical work. You can talk to the person who coded your car.

What you're told

Dealer service department

A service advisor relaying notes from the shop floor.

Pro Tech

What failed, what we're installing, what it costs — before you approve anything. Warranty terms in writing, including the module exception.

Fair is fair — warranty work, recalls, and manufacturer software campaigns belong at the dealer. Everything else on this page, we handle.

The process

How a module job runs.

Five steps, no mystery. The coding is part of the quote from the start — not a surprise line at pickup.

  1. 01

    Diagnose the module

    Confirm the module actually failed — not its wiring, its fuse, or a fault upstream. No module gets ordered until the diagnosis says so.

  2. 02

    Source the OEM unit

    We quote the OEM module — new, or used where a used unit is viable — with the coding included in the number you approve.

  3. 03

    Install

    Clean physical installation: trim, connectors, and seals handled the way we'd want on our own car.

  4. 04

    Code it to the VIN

    The module is adapted and configured to your vehicle — VIN, options, equipment. On Audi and VW, component protection is cleared at this step.

  5. 05

    Verify and clear

    Functions tested, module-swap faults cleared, codes rescanned. You get the keys back when the module behaves like it left the factory in that car.

These guys are incredible. They are young but very knowledgeable. They solved my electrical issues (BMW x7) for half the price of my local BMW dealer. Highly recommend this garage.

FAQ

Programming FAQ

What drivers ask before bringing us a module job.

  • 01

    Which brands and models can you code and program?

    Audi, Volkswagen, BMW, and Mercedes are our daily work — adapting replacement and retrofit control modules, enabling features, and clearing module-swap faults. The heaviest module-replacement work runs on Audi and BMW: headlight and adaptive-headlight modules, comfort and body modules, and similar control units. Tell us the year, model, and module when you book and we'll confirm before you commit to anything.

  • 02

    My Audi says "component protection active" after a module was replaced. Can you fix it?

    Yes. Component protection is VW Group's anti-theft lock — it keeps a swapped-in module (used or brand new) restricted until it's cleared through factory-level online authorization, which is normally a dealer-only visit. We handle that clearance on replacement modules for Audi and Volkswagen, so the part you already paid for actually works.

  • 03

    Do I really not have to go to the dealer for this?

    For module replacement, coding, programming, and component protection — no. We handle it start to finish. The honest exceptions: active warranty work, recalls, and manufacturer software campaigns still belong at the dealer, because the manufacturer pays for those. If your job is one of them, we'll tell you instead of charging you for it.

  • 04

    How much cheaper than the dealer are you, honestly?

    There's no universal number, so we won't invent one. Dealers often quote module failures as full-assembly replacements at dealership labor rates; we quote the failed module, the labor, and the coding — itemized, in writing, before work starts — and that number typically comes in well below the dealer's. Get their estimate and ours, and compare line by line.

  • 05

    What's the warranty on module replacement?

    Spelled out before you pay: no warranty on the module itself, a 30-day warranty on our labor, and whatever warranty the part's manufacturer offers passed through to you. Module work is the specific exception to our standard parts-and-labor terms, which is why it goes on the estimate and the invoice in writing.

  • 06

    Can you install a used module instead of a new one?

    Often, yes — a used OEM module saves real money, especially on headlight and body modules. The catch is that a used module arrives married to its donor vehicle: on Audi and VW it stays in component protection until cleared, which we handle. Some modules aren't viable used at all, depending on brand and module — we'll tell you before you buy the part, not after.
