MG ZS Rear Bumper Replacement: Gen 1 & Gen 2 Variants, OEM Numbers & Fitment Tips

Why MG ZS Rear Bumpers Need Replacing

The rear bumper on the MG ZS is a large plastic fascia that wraps the entire lower rear of the vehicle. It is the first point of contact in the majority of reversing incidents and low-speed car park collisions. Unlike metal panels, plastic bumper covers are not straightforward to repair — cracks, splits and deep gouges generally require full replacement rather than filler and respray, particularly when the structural foam absorber behind the cover is also deformed.

Common damage scenarios that result in rear bumper replacement include:

• Car park reversing impacts — the most frequent cause; a 10–15 km/h contact with a bollard, wall or another vehicle is enough to crack or split the lower bumper cover
• Rear-end collisions — even low-speed rear-end hits typically destroy the bumper cover and deform the foam absorber behind it; the tow bar mount area and exhaust finisher surrounds are especially vulnerable
• Sensor damage from impact — the rear parking sensors are mounted through the bumper cover; a direct hit can crack the aperture surrounds even when the sensor itself survives
• Fading and UV degradation — less common but relevant for early Gen 1 vehicles; unpainted lower sections can fade significantly after several years of Australian sun exposure

MG ZS Rear Bumper Variants: Gen 1 vs Gen 2

The MG ZS has gone through two distinct generations in Australia, and the rear bumper differs substantially between them. Ordering without confirming the generation is the most common mistake, as the covers are not interchangeable.

Gen 1 MG ZS (2017–2021)

The original MG ZS sold in Australia from 2017 through to the 2021 model year uses a rear bumper with a relatively simple lower profile. Key characteristics of the Gen 1 rear bumper:

• Four circular parking sensor apertures on models equipped with rear PDC (Essence grade); Excite and entry grades have a plain lower section with no apertures or blanked apertures
• Single exhaust outlet cut-out on the lower right-hand side
• No tow bar provision aperture on standard models — the bumper cover is solid plastic across the lower skid area
• Chrome-finish lower diffuser trim strip on Essence grade; body-colour or matte black lower section on lower grades

Relevant Gen 1 OEM part numbers:

• 10245892 — rear bumper cover assembly, Gen 1, Essence grade (with sensor apertures)
• 10228904 — rear bumper cover assembly, Gen 1, Excite / base grade (without sensor apertures)

Gen 2 MG ZS / Facelift (2021+)

The Gen 2 MG ZS introduced a substantially revised rear-end design, including a new bumper profile with a wider lower diffuser section and updated sensor aperture positions. Gen 2 rear bumpers are not compatible with Gen 1 bodies and vice versa.

• Revised sensor aperture positions — slightly wider spacing compared to Gen 1, and the lower apertures sit closer to the diffuser edge
• Updated exhaust finisher integration — the Gen 2 bumper has revised cut-outs that accommodate the reshaped exhaust tip surrounds used on the updated powertrain
• Tow bar provision aperture available on Gen 2 — some Gen 2 models have a small blanked section in the lower skid area that can be punched out for a tow bar wiring loom; confirm with your VIN whether this provision is present
• Gloss black lower diffuser section standard across most Gen 2 grades; chrome strip deleted

Fitment Tips: What to Check Before Ordering

Even within the same generation, the MG ZS rear bumper has enough variation between grades and build dates to cause fitment problems if the wrong part is ordered. The following are the most important things to verify before dispatch:

Sensor Hole Configuration

Not all MG ZS models are fitted with rear parking sensors from the factory. The Excite and base grades in Gen 1 were not standard with rear PDC. If your vehicle does have sensors, the replacement cover must have the correct number of apertures (typically four) in the correct positions. Installing a plain cover on a PDC-equipped vehicle requires drilling, which risks cracking the new bumper if done incorrectly.

Tow Bar Provisions

Aftermarket tow bars are common on Australian MG ZS vehicles. If the vehicle has a tow bar fitted or a tow bar wiring loom, the replacement bumper cover must accommodate the tow bar tongue and any wiring access points. Some bumper covers have a factory blanked tow bar aperture in the lower skid section that is removed during tow bar installation — confirm with the repairer whether this applies to the vehicle being repaired before ordering.

Exhaust Finisher Cut-Outs

The exhaust outlet position and finisher shape changed between Gen 1 and Gen 2, and there are minor differences between grade levels within each generation. On Gen 2 Essence grade models the exhaust tip surrounds extend further into the lower bumper section. Using a bumper cover with the wrong exhaust cut-out profile will result in a visible gap or the cover fouling on the exhaust tip.

Confirming Fitment Using VIN

The safest approach is to provide your VIN when requesting a quote. The VIN encodes the exact build specification — including model year, market variant, grade and factory-fitted options — which allows us to cross-reference the correct OEM part number before dispatch. We confirm fitment against the VIN on every order, which eliminates wrong-part risk and avoids the delays and cost of returning incorrect parts.

For Panel Shops and Smash Repairers

MG ZS rear bumper replacements are a routine job for Australian smash repairers, and the volume of MG ZS vehicles in the fleet means demand is consistent. 888 Auto Parts supplies brand new OEM-specification rear bumper covers for both Gen 1 and Gen 2 MG ZS from our Melbourne warehouse, with fitment confirmed against the vehicle VIN before dispatch.

Trade accounts are available for panel shops and smash repair businesses. Trade pricing applies to the full range of MG and Chery crash parts, not just bumpers. To get started, submit a quote request with the vehicle VIN and a parts list, and include your business name so we can set up a trade account.

For the full crash parts range, see the MG ZS parts catalogue or read the MG ZS parts guide for an overview of what is available and how ordering works.

For Private MG ZS Owners

If you own an MG ZS and need a rear bumper replacement — whether you are managing the repair yourself, going through a smash repairer, or making an insurance claim — the process for ordering the correct part is straightforward.

Locate your VIN (it is printed on the driver's door jamb sticker and at the base of the windscreen on the driver's side), note your model year from your registration papers, and submit a quote request with that information. If you know your grade level (Vibe, Excite or Essence) include that too, as it affects the sensor aperture and trim configuration of the correct cover.

Parts are shipped from our Melbourne warehouse. If you are working with a repairer, we can supply directly to the repairer's address. Visit the MG ZS vehicle page for more information on the parts we stock for this model.
