Quick Summary: 5K0827505A is a Volkswagen boot or tailgate lock reference. You may also see it written as 5K0 827 505 A, with spaces between the same letters and digits. ERA lists both this number and the extended A 9B9 reference against its 660273 replacement. This guide explains the related numbers, the catalogue specifications and the details to compare when choosing a replacement.
You have found the number on your old lock, but the replacement listings show several other numbers beside it. One seller calls the part a tailgate latch; another calls it a boot lock actuator. Before deciding that the cheapest offer is the same item, establish which complete assembly the seller is actually offering.
What part is the 5K0827505A tailgate lock?
ERA's official catalogue identifies its 660273 replacement as a lock fitted at the boot. The entry gives a 100 mm mounting-bore distance, two mounting holes and “Number of connectors: 4.” These specifications describe ERA 660273; use them as comparison points when looking at another supplier's part.
Reference What the manufacturer catalogue establishes 5K0 827 505 A
5K0827505ASpaced and compact forms of the reference listed against ERA 660273. 5K0 827 505 A 9B9 Also listed against ERA 660273. Preserve the additional characters when copying a full label. 1K6 827 505 E Another comparison reference in the same ERA entry, not a dated VW supersession statement. 5K0 827 505 C 9B9 Listed separately in VIEROL's 2025 brochure against VEMO V10-85-0058. That entry alone does not establish an A-to-C replacement chain.
What do the related part numbers mean?
The table is a way to understand different listings. When ERA associates several OE numbers with one replacement, that is an aftermarket cross-reference. It does not, by itself, establish that Volkswagen officially replaced one number with another.
If a seller offers 5K0827505C instead of 5K0827505A, ask for the offered brand, full part number and application record. VIEROL lists a C 9B9 reference for its VEMO product, but a later letter alone is not enough to confirm a replacement. An OE number in a listing also does not mean that the item is a genuine Volkswagen part.
Which Volkswagen models appear in the catalogue?
ERA groups its 660273 boot-lock replacement under Volkswagen Golf, Passat, Passat Alltrack, Tiguan and Touran. This provides model-family context, but the entry covers several comparison numbers and does not establish exact model-year fitment for every number.
Three details to compare on a replacement lock
Vehicle details. Use the model generation, body style and production details, with a VIN check through a suitable parts catalogue when available. “Golf” or “Passat” alone leaves too much open: the body style and complete part reference belong in the same replacement request.
Label and connector. Compare three views of the actual part: the readable number, the electrical socket face and the mounting side. The socket view should show the terminal layout and housing shape. The mounting view should show both holes and the latch opening. Ask for the offered unit's photographs, because a catalogue illustration may represent a product family rather than the exact version being quoted.
Mounting points. Use the documented dimensions to ask a precise question. For example, request the centre-to-centre distance between mounting holes, with a clear measurement photo, instead of asking whether the new lock “looks the same.” Matching that dimension is helpful, but the connector and application still have to agree.
Choose what you are buying before comparing prices
Specify whether you want a new genuine part, a named aftermarket replacement or a used assembly. Those are different offers even when every listing mentions 5K0827505A. Ask whether the price includes the complete lock assembly shown, and identify any separate fittings or accessories you require.
For a used part, request photographs of that individual unit and a clear account of how its operation was checked. For a new aftermarket part, ask for the manufacturer and its own product code. A supplier's “tested” claim becomes more useful when it describes what was tested; it should not be interpreted as a service-life prediction.

FAQ
Is 5K0827505A a tailgate lock or a door handle?
The reference is associated with a boot or tailgate lock assembly in the manufacturer catalogue cited here. Ask for the exact assembly; a handle, release button or trim piece is a different purchase description.
Are 5K0827505A and 5K0 827 505 A the same reference?
Yes. The spaces change the formatting, not the letters or digits. Keep any further suffix shown on the original label, such as 9B9, when requesting a replacement.
Can I replace 5K0827505A with 5K0827505C?
Do not decide from the letter alone. Ask the supplier or an authorised parts department to confirm the proposed full reference against the vehicle. The two catalogues cited here do not provide a VW supersession chain between them.
Does a matching connector prove that the lock fits?
No. The mounting arrangement, latch geometry and confirmed vehicle application also matter. A socket photograph is one part of the comparison, not the complete fitment decision.
What should I send for a China purchasing inquiry?
Start with the complete part number, required quantity, destination and any supplier link. Include the offered brand and condition if known, and explain whether you need the original reference or are considering a documented alternative.
