Mercedes-Benz EQC Service & Repair in Hyderabad
N293 · EQC 400 4MATIC · ~80 kWh HV battery · dual-motor 4MATIC · single-speed reduction gear · XENTRY HV diagnostics · genuine MB parts · 1-yr warranty
The Mercedes-Benz EQC was the brand's first dedicated electric SUV and, for many Hyderabad owners, the car that introduced them to premium electric motoring — the GLC-sized EV that made a proper luxury EV feel normal. Built on the N293 platform, the EQC 400 4MATIC sold here uses a roughly 80 kWh lithium-ion high-voltage battery driving a dual-motor all-wheel-drive system, with each motor turning a fixed single-speed reduction gear rather than any conventional gearbox. As an early EV it is now the generation most likely to be out of warranty and in need of a specialist who understands high-voltage battery health — and at Metre Per Second we service it with factory-grade Star Diagnosis (XENTRY / DAS), full HV safety procedures, insulation and battery-health testing, and genuine Mercedes-Benz parts at 35–50% below dealer cost.
Servicing an EQC is nothing like servicing a diesel GLC: there is no engine oil, no timing chain, no DPF and no spark plugs, but there is a large, ageing high-voltage battery whose cooling and cell balance are the single most important things to monitor, plus reduction-gear oil, brake fluid, regen-corroded brakes, a hard-working thermal-management system and a 12V battery that quietly runs the whole car. As one of the earliest EVs in Hyderabad, the EQC especially benefits from a proper battery state-of-health report so owners know exactly what capacity they have. Metre Per Second is set up for this — HV-qualified technicians, insulation-resistance and battery-health testing on XENTRY, genuine and OEM-supplier parts (Bosch, Mahle, Continental, ATE), correct-spec HV coolant and SCN online coding. Every EQC 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: N293 · Body type: Fully Electric Luxury Mid-Size SUV (EV adaptation of the GLC platform) · Years sold: 2020 – 2023 (the N293 EQC was Mercedes-Benz's first mainstream electric SUV in India and one of the earliest premium EVs on Hyderabad roads)
Engines — Mercedes-Benz EQC
- EQC 400 4MATIC (dual motor) (Front + rear asynchronous (ASM) motors, ~300 kW / 408 hp combined) — Two asynchronous motors — one per axle — give permanent 4MATIC all-wheel drive from the ~80 kWh battery. The motors are robust; service focus is each unit's reduction-gear oil, the extensive motor/inverter coolant circuit and the 12V auxiliary battery. No engine oil or spark plugs.
- Front drive unit (Front ASM motor + single-speed reduction gear) — Tuned for efficiency at cruising speeds; the reduction gear is a sealed lifetime fill but is inspected for weep and bearing noise on high-mileage cars.
- Rear drive unit (Rear ASM motor + single-speed reduction gear) — Provides the bulk of dynamic performance; watched for coolant-circuit integrity and mounting-bush wear on Hyderabad roads.
- High-voltage battery (~80 kWh lithium-ion (NMC), ~400 V architecture) — Liquid-cooled floor pack with cell-monitoring modules. On this early EV, state-of-health, cell balance and insulation resistance are the priority checks; Hyderabad heat makes battery cooling performance the item to watch for range and charge speed.
Transmission & Drivetrain
- Dual-motor 4MATIC with single-speed reduction gears (4MATIC) — applies to EQC 400 4MATIC (all EQC). The EQC has no gearbox to shift — each of the two motors drives through a fixed single-speed reduction gear, so there are no shift-quality or clutch faults. All-wheel drive is permanent via the front and rear motors, with torque split managed electronically by the drive-control units and verified on XENTRY. Reduction-gear oil is a sealed lifetime fill by MB; we inspect both units for weep on high-mileage cars.
- Electric all-wheel drive (front + rear motors) (4MATIC) — applies to EQC 400 4MATIC. AWD comes from two independent electric axles rather than a transfer case or prop-shaft, so there is no transfer-case fluid or Haldex coupling to service — drive distribution is checked and coded on XENTRY.
Suspension & Brakes
Suspension: Multi-link front and rear (four-link front) with passive dampers; the heavy floor-mounted battery gives the EQC a planted but firm ride. No AIRMATIC on this platform.
The EQC is a heavy SUV — the battery adds substantial mass low in the chassis — so front control-arm bushes, strut mounts and anti-roll-bar links wear sooner than on a lighter petrol car, and tyres wear faster, all accelerated by Hyderabad speed breakers and pot-holes. These are conventional repairs with genuine/Bilstein parts. We also check the underbody battery guard and mounting after any kerb or speed-breaker impact, as the pack floor sits low, and inspect the subframe bushes that this platform loads heavily.

Common EQC Faults & Hyderabad Pricing
| Area | Symptom | Root Cause | Fix Price (INR) |
|---|---|---|---|
| HV battery / cooling | Reduced range, slower DC charging, battery-temperature warning | Battery coolant degradation, cooling-pump wear or cell-balance drift on an ageing early-EV pack (worsened by Hyderabad heat) | ₹18,000 – ₹1,80,000 |
| 12V auxiliary battery | Car will not wake / power up, random warnings, no charging start | 12V battery failure — the EQC cannot boot the HV system on a weak 12V, a very common EV fault | ₹10,000 – ₹26,000 |
| Regenerative brakes | Grinding, squeal, uneven braking, corroded discs | Discs and calipers under-used because regen does most braking, so they corrode and caliper slides seize | ₹14,000 – ₹55,000 |
| Charging | Will not accept AC/DC charge, charge-port flap fault | On-board charger, HV DC-DC converter, charge-port actuator or HV interlock fault | ₹18,000 – ₹1,30,000 |
| Thermal management | Weak cabin cooling, poor battery pre-conditioning, coolant loss | Coolant-valve actuator, electric coolant pump or refrigerant-circuit fault in the shared thermal system | ₹16,000 – ₹90,000 |
| Suspension / tyres | Knock over bumps, fast/uneven tyre wear | Front control-arm bushes / strut mounts / subframe bushes worn under battery weight | ₹16,000 – ₹55,000 |

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 risks the ageing 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 EQC no-start cause.
- Brake fluid — MB-approved DOT 4 / DOT 4 Plus. Still needs 2-yearly changes — regen means fluid ages from moisture, not heat, and old fluid corrodes the ABS/regen hardware.
- Reduction-gear oil — Genuine MB e-drive reduction-gear oil (front & rear unit-specific). Sealed lifetime fill but inspected for weep and bearing noise on both units on high-mileage cars.
- Cabin / HEPA filter — Genuine MB combination/active-carbon cabin filter. Keeps fine-dust and odour filtration effective in dusty, humid Hyderabad conditions.
- Brake pads/discs & tyres — Genuine MB / ATE / Continental EV-spec friction; correct load-rated tyres. Anti-corrosion friction suits regen-braked discs; load-rated tyres suit the heavy SUV.
Star Diagnosis (XENTRY) — EQC
Every EQC 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, HV DC-DC converter, thermal-management valves and pumps, ESP, SAM, MBUX and driver-assist modules. On an early EV the battery report is especially valuable. 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 — EQC
Can you service a Mercedes EQC 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 EQC needs completely different servicing from a diesel GLC — no oil or spark plugs, but battery health, cooling, brake fluid, regen brakes and the 12V system all need attention.
The EQC is an early EV — should I get a battery health check?
Definitely. As one of the earliest premium EVs in Hyderabad, an EQC benefits hugely from a XENTRY battery report showing state-of-health, cell balance and insulation resistance. It tells you the real usable capacity — essential if range has dropped, or before buying or selling a used EQC.
How much does an EQC service cost in Hyderabad?
EV servicing saves on consumables — a minor Service A is typically ₹14,000–₹22,000 and a major Service B ₹22,000–₹36,000 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 EQC will not power up — is the big 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 charged. We test it and, if needed, fit and code a genuine MB 12V AGM battery on XENTRY — a quick, inexpensive fix.
Why are the brakes grinding when I hardly use them?
On the EQC regen does most of the braking, so the discs and calipers are under-used and corrode or seize 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.
My EQC range has dropped in the summer — what can you do?
Heat and an ageing pack both affect range. We check the battery cooling circuit, coolant condition, cell balance and thermal-management on XENTRY, repair any cooling-pump or valve fault, and advise on charging habits. We will also give you a state-of-health figure so you know what is battery ageing versus a fixable fault.
Is it safe to service my EQC 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 EQC 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 EQC
As one of the first EQC owners in Hyderabad I struggled to find anyone who could service it properly. MPS ran a full XENTRY battery health report, checked the cooling and did the brakes. Genuinely knowledgeable about EVs and far cheaper than the dealer. Picked up from Jubilee Hills.
Range had dropped and I feared the worst. They diagnosed a battery cooling issue rather than a dead pack, fixed the cooling circuit and gave me a state-of-health report. Range improved and I finally understand my car. Very honest team.
Car wouldn't wake up one morning. MPS found it was the 12V battery, not the main one, coded a genuine replacement on XENTRY and saved me a huge panic and dealer bill. Free pickup from Gachibowli. Highly recommend for EVs.
Brakes were grinding despite low usage. They explained regen corrodes the discs, overhauled the calipers with genuine parts and changed the fluid. Clear estimate and great communication. Dropped back to Kondapur. Excellent EV service.
