Mercedes-Benz EQB Service & Repair in Hyderabad
X243 · EQB 300 4MATIC / EQB 350 4MATIC · 66.5 kWh HV battery · dual-motor 4MATIC · single-speed reduction gear · 7-seat · XENTRY HV diagnostics · 1-yr warranty
The Mercedes-Benz EQB is the electric version of the GLB — and the rare battery-electric SUV that offers a genuine third row, which makes it a natural first EV for Hyderabad families upgrading from a GLB or GLC. Built on the X243 platform, it carries a roughly 66.5 kWh lithium-ion high-voltage battery and, in the versions sold here, a dual-motor 4MATIC drivetrain (EQB 300 4MATIC and the more powerful EQB 350 4MATIC), each motor driving through a fixed single-speed reduction gear rather than a multi-ratio gearbox. At Metre Per Second we service the EQB with the same factory-grade Star Diagnosis (XENTRY / DAS) used on the combustion Mercedes range, plus the high-voltage safety procedures, insulation testing and battery-health diagnostics an EV requires — all with genuine Mercedes-Benz parts at 35–50% below dealer cost.
Owning an EQB in Hyderabad means the servicing conversation shifts entirely: forget engine oil, timing chains, DPFs and spark plugs, and focus instead on high-voltage battery health, the dedicated battery and power-electronics cooling circuit, reduction-gear oil, brake fluid, regen-affected brakes, the 12V system and — because it is a family seven-seater — the tyres, which take a beating under the added battery mass. Metre Per Second is built for this: HV-qualified technicians, battery state-of-health and insulation-resistance testing on XENTRY, genuine and OEM-supplier parts (Bosch, Mahle, Continental, ATE), correct-spec HV coolant and SCN online coding for any module work. Every EQB job comes with a written fixed-price estimate before work starts and a 1-year MPS warranty, and free pickup and drop covers Gachibowli, Jubilee Hills, Banjara Hills, Hitech City, Kondapur and KPHB.
Chassis codes: X243 · Body type: Fully Electric Luxury Compact SUV with optional 7 seats (EV adaptation of the GLB X247 platform) · Years sold: 2022 – present (the X243 EQB, Mercedes-Benz's electric 7-seat compact SUV, a growing choice for Hyderabad families wanting a three-row EV)
Engines — Mercedes-Benz EQB
- EQB 300 4MATIC (dual motor) (Front ASM + rear PSM motor, ~168 kW / 228 hp combined) — Dual-motor all-wheel drive fed by the ~66.5 kWh battery. Both drive units are reliable; service focus is the reduction-gear oil on each unit, the motor/inverter coolant circuit and the 12V auxiliary battery. No engine oil or spark plugs.
- EQB 350 4MATIC (dual motor) (Front ASM + rear PSM motor, ~215 kW / 292 hp combined) — The higher-output variant draws more current, so battery cooling and DC-charge behaviour matter more in Hyderabad heat. Attention points are cooling performance, cell balance and the same reduction-gear/12V items as the 300.
- High-voltage battery (~66.5 kWh lithium-ion (nickel-rich NMC), ~420 V architecture) — Liquid-cooled floor-mounted pack with cell-monitoring modules. State-of-health, cell balance and insulation resistance are checked on XENTRY; a seven-seat family car with a large usable capacity makes real range and battery cooling worth monitoring.
- On-board charger & DC (11 kW AC on-board charger / ~100 kW DC fast charging) — On-board charger, HV DC-DC converter and charge-port actuator are the electrical service points; charging faults are diagnosed on XENTRY rather than by guesswork part swaps.
Transmission & Drivetrain
- Dual-motor 4MATIC with single-speed reduction gears (4MATIC) — applies to All EQB variants (300 / 350 4MATIC). The EQB has no gearbox to shift — each motor drives through a fixed single-speed reduction gear, so there are no shift-quality or clutch faults. All-wheel drive comes from engaging the rear synchronous motor electronically, with torque split managed by the drive-control units and verified on XENTRY. Reduction-gear oil is a sealed lifetime fill by MB; we inspect for weep and check level on high-mileage cars.
- Electric all-wheel drive (rear PSM motor) (4MATIC) — applies to EQB 300 / 350 4MATIC. AWD uses the rear motor rather than a mechanical transfer case or prop-shaft, so there is no transfer-case fluid or Haldex coupling to service — traction behaviour is checked and coded on XENTRY.
Suspension & Brakes
Suspension: MacPherson-strut front, multi-link rear with passive dampers; the floor-mounted battery makes the seven-seat EQB heavy, so it rides firmer than a GLB. No AIRMATIC on this platform.
A fully-loaded seven-seat EV is heavy, and that weight — plus Hyderabad speed breakers and pot-holes — wears front lower-arm bushes, strut mounts and anti-roll-bar links sooner than on a petrol GLB, and chews through tyres faster, especially on the rear axle under load. These are conventional repairs with genuine/Bilstein parts. We also inspect the underbody battery guard and its mounting after any kerb or speed-breaker strike since the pack floor sits low and exposed.

Genuine & OEM Parts
- HV battery coolant — Genuine MB battery/electronics coolant (correct low-conductivity spec). Never use ordinary engine coolant in the HV circuit — the wrong conductivity/corrosion spec endangers the pack.
- 12V auxiliary battery — Genuine MB AGM 12V battery (correct capacity & coding). Coded to the car on XENTRY so charging strategy is correct; the single most common EV no-start cause.
- Brake fluid — MB-approved DOT 4 / DOT 4 Plus. Still needs 2-yearly changes even with light regen-assisted use — fluid ages from moisture more than heat.
- Reduction-gear oil — Genuine MB e-drive reduction-gear oil (front & rear unit-specific). Sealed lifetime fill but inspected for weep on both units on high-mileage cars — no clutch or ATF service.
- Cabin / HEPA filter — Genuine MB combination/active-carbon cabin filter. Keeps fine-dust and odour filtration effective across all three rows in dusty Hyderabad conditions.
- Brake pads/discs & tyres — Genuine MB / ATE / Continental EV-spec friction; correct load-rated tyres. EV-appropriate, anti-corrosion friction plus proper load-index tyres for the heavy seven-seater.
Star Diagnosis (XENTRY) — EQB
Every EQB begins with a full Mercedes XENTRY / DAS high-voltage diagnostic — battery-management system (state-of-health, cell voltages and balance, insulation resistance), power electronics, both front and rear drive units, on-board charger, DC-DC converter, thermal-management valves, ESP, SAM, MBUX and driver-assist modules. As an EV, all work follows Mercedes HV safety protocol: the pack is safely de-energised and verified before any high-voltage repair. We perform SCN online coding, control-unit programming, 12V battery registration and after-repair calibrations (steering-angle, camera/radar) so the car leaves fault-free.
Frequently Asked Questions — EQB
Can you service a Mercedes EQB electric SUV in Hyderabad?
Yes. We are equipped for EVs with HV-qualified technicians, XENTRY high-voltage diagnostics, insulation and battery state-of-health testing, and Mercedes HV safety procedures. The EQB needs different servicing from a petrol GLB — no oil or spark plugs, but battery health, coolant, brake fluid, regen brakes, tyres and the 12V system all need attention.
How much does an EQB service cost in Hyderabad?
EV servicing saves on consumables — a minor Service A is typically ₹13,000–₹20,000 and a major Service B ₹20,000–₹32,000 with no engine oil, filter or spark plugs. We give a fixed written quote after a free inspection, usually 35–50% below dealer pricing with genuine parts.
My EQB will not power up in the morning — is the main battery dead?
Usually not. The most common EV no-start is a weak 12V auxiliary battery, which the car needs to boot the high-voltage system even when the drive battery is full. We test it and, if needed, fit and code a genuine MB 12V AGM battery on XENTRY — a quick, inexpensive fix.
The EQB is a heavy seven-seater — does that affect servicing?
Yes. The battery plus seven-seat load makes tyres, suspension bushes and strut mounts wear faster than on a lighter car, and we recommend regular tyre rotation and a suspension audit. We use genuine/Bilstein parts and correct load-rated tyres so the ride and safety margins stay right.
Do the brakes still wear on an electric EQB?
They corrode more than they wear. Regen does most of the braking, so the discs and calipers are under-used and rust or seize, especially in humid Hyderabad. We clean and lubricate caliper slides, overhaul or replace corroded discs with genuine/ATE parts, and change the brake fluid on schedule.
Can you give me a battery health report for a used EQB?
Yes — on XENTRY we read state-of-health, cell balance and run an insulation-resistance test, then give you a written battery report showing real capacity. It is invaluable before buying or selling a used EQB, or if you notice reduced range in the summer heat.
Is it safe to service my EQB outside the Mercedes dealership?
Absolutely. We follow Mercedes HV safety protocol, use genuine/OEM parts and full XENTRY diagnostics with SCN coding, and issue a 1-year warranty. For cars out of factory warranty, an independent EV-capable specialist like MPS gives you dealer-grade work at a much lower cost.
Do you offer free pickup and drop for EQB service?
Yes — free pickup and drop across Gachibowli, Jubilee Hills, Banjara Hills, Hitech City, Kondapur, KPHB and the wider Hyderabad area on any service. Call or WhatsApp 8555824915.
Customer Reviews — Mercedes EQB
Bought the EQB for the seven seats and use it as a family car. MPS did a full EV service — battery health report, brake overhaul and tyre rotation — and explained everything clearly. Half the dealer cost and picked up from Kondapur. Very impressed with their EV knowledge.
Range dropped noticeably in the summer. They checked the battery cooling and coolant on XENTRY, sorted the cooling circuit and advised on charging habits. Range is back and they were completely transparent about pricing. Free drop to Banjara Hills.
Car would not start one morning — turned out to be the 12V battery, not the main pack. MPS diagnosed and coded a genuine one quickly. Saved me a panic and a huge dealer bill. Honest, knowledgeable EV team in Hyderabad.
Grinding brakes despite barely using them — they explained regen makes the discs corrode and overhauled the calipers with genuine parts. Tyres were also wearing fast from the weight so they rotated and advised. Great full service. Picked up from Hitech City.
