What the gateway and BCM actually control
The gateway is the traffic controller for the car’s data buses: every module that wants to talk to another module goes through it. The body control module (BCM) sits below it and owns the things you touch every day — lights, wipers, central locking, window motors. A failing gateway shows up as unrelated faults across several systems at once; a failing BCM shows up as one body function that stopped working.
Why the index matters more than the part family
There are dozens of BCM and gateway indexes that share a housing and a connector. Higher indexes generally support more equipment — trailer modules, LED lighting, keyless entry — and lower ones simply have no coding option for functions they were never built to drive. Upgrading to a higher index is a common retrofit, but it needs the coding dataset for your exact car, not a generic one. Fitting a higher-index module without the right dataset can leave you with more faults than you started with.
Symptoms that point at the module
Intermittent “works when cold” behaviour across several unrelated functions, a bus that goes to sleep and never wakes, lights that flicker in time with the wipers, or a scan that reports modules which are not fitted to the car. Before replacing anything, check the grounds and the battery — low voltage produces exactly the same symptoms and costs nothing to rule out.
Why the index after the part number decides fitment
Volkswagen Group part numbers end in an index letter, and that letter is not cosmetic: it marks a revision. A B revision replaces an A, a C replaces a B, and sometimes a later index will not work in an earlier car because the software or the connector changed at the same time. When a listing shows two numbers separated by a slash, both fit the applications in the table; when it shows one, that is the number we ship. If your old part carries an index we do not list, send us a photo of the label — the number on the part always beats the number in a catalogue.
Ordering more than one
Workshops and resellers order in sets: two of a sensor, four of a camera, a matched pair of modules. We ship from stock and combine postage where the parts are in the same warehouse, and we can quote wholesale pricing for repeat orders. Tell us the quantities and the destination country when you ask, so the shipping figure you get is the real one rather than an estimate.
Fitment check before ordering
Volkswagen Group builds the same looking part in several versions, and the differences are in the number stamped on the housing rather than in the shape. Before you order, compare the number on your old unit with the one in the title — a module that is physically identical but one index out will often fit and power up, then refuse to communicate or code. If you cannot read the old number, send us the VIN and a photo of the connector side and we will identify it for you.
What to expect on delivery
Every unit is checked and photographed before dispatch, packed with foam and shipped with tracking. Electronic parts are tested on a bench where the test is possible without the donor car; where it is not, we say so in the listing rather than promise a test we cannot perform. Keep the packaging until the part is fitted and working.
Shipping, customs and delivery times
Orders leave within one to two working days once payment clears. We ship worldwide with tracking, and the tracking number reaches you by email as soon as the parcel is handed to the carrier. Delivery time depends on the destination and the service chosen — a few days inside Europe, one to three weeks elsewhere — and customs charges, where they apply, are the buyer’s responsibility. If you need a part by a specific date, tell us before ordering and we will confirm what is achievable rather than promise a date we cannot hold.
Returns and warranty claims
If a part arrives damaged, photograph the packaging before opening it fully and contact us the same day. If a part fails inside the twelve-month warranty, send us the fault description and a scan report where you have one — most electronic failures can be diagnosed from the fault memory without returning anything. Parts that have been coded, modified, opened or damaged by incorrect fitting fall outside the warranty, which is why we ask you to read the fitting notes first.
Checking a module before you fit it
Before you install anything, photograph the label on the part you are removing and compare every character with the number in the listing. Plug the new module in, read the fault memory, and only then start coding — if something is wrong, an uncoded module is easy to return and a coded one is not. Keep the original part until the replacement is working; once the car is back together it is the only reference you have.
After fitting
Most electronic modules in this catalogue need coding, adaptation or component protection removal before they work in your car. That work is a paid service quoted separately — we can do it remotely if you have a laptop, a compatible interface and a stable internet connection, or talk your workshop through it. Fitting the part and expecting it to work without coding is the single most common reason a retrofit appears to have failed.
Coding & technical services
Most electronic parts require coding or programming after installation. Remote coding, programming and installation guidance are paid services quoted separately — contact us for a quote.
