Mercedes-Benz EQS Service & Repair in Hyderabad
V297 · EQS 450+ / EQS 580 4MATIC · up to 107.8 kWh battery · single-speed reduction gear · AIRMATIC · rear-axle steering · MBUX Hyperscreen · XENTRY HV diagnostics · 1-yr warranty
The Mercedes-Benz EQS is the electric flagship — effectively the S-Class of the EV world — and the most technically advanced car in the entire EQ range. Built on the bespoke V297 (EVA2) electric platform, it carries a very large lithium-ion battery of up to roughly 107.8 kWh, running on a 400V architecture, driving either a single rear motor (EQS 450+, rear-wheel drive) or a dual-motor 4MATIC setup (EQS 580 4MATIC), always through a fixed single-speed reduction gear. Layered on top are AIRMATIC air suspension, rear-axle steering for its limousine footprint, and the vast MBUX Hyperscreen — systems that demand real diagnostic depth. At Metre Per Second we service the EQS with factory-grade Star Diagnosis (XENTRY / DAS), full high-voltage safety procedures, insulation and battery-health testing, AIRMATIC repair capability and genuine Mercedes-Benz parts at 35–50% below dealer cost.
An EQS combines everything demanding about a flagship S-Class with everything demanding about a modern EV. There is no engine oil, timing chain, DPF or spark plugs, but there is a very large, expensive high-voltage battery whose cooling, cell balance and state-of-health are paramount; AIRMATIC air struts and a compressor that leak and wear; rear-axle steering actuators that need calibration; regen-corroded brakes; reduction-gear oil; a 12V system that boots the entire car; and the Hyperscreen and driver-assist suite that need proper coding after any work. Metre Per Second is equipped for all of it — HV-qualified technicians, insulation-resistance and battery-health testing on XENTRY, AIRMATIC strut/compressor repair with genuine/Bilstein parts, SCN online coding and after-repair calibration, plus correct-spec HV coolant. Every EQS job leaves 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: V297 · Body type: Fully Electric Luxury Flagship Sedan (bespoke EVA2 electric platform) · Years sold: 2022 – present (the V297 EQS, Mercedes-Benz's electric flagship sedan and the S-Class of EVs, a statement car for Hyderabad's luxury buyers)
Engines — Mercedes-Benz EQS
- EQS 450+ (rear motor) (Single rear permanently-excited synchronous (PSM) motor, ~245 kW / 333 hp) — Rear-wheel-drive single-motor flagship fed by the large battery, tuned for maximum efficiency and range. Service focus is the reduction-gear oil, the extensive coolant circuit, AIRMATIC and the 12V system. No engine oil or spark plugs.
- EQS 580 4MATIC (dual motor) (Front + rear PSM motors, ~385 kW / 523 hp combined) — Adds a front synchronous motor for 4MATIC all-wheel drive and strong performance. Higher current draw makes battery cooling and DC-charge behaviour, plus two reduction-gear units, the key checks alongside AIRMATIC and rear-axle steering.
- High-voltage battery (Up to ~107.8 kWh lithium-ion (NMC 811), 400V architecture) — Very large liquid-cooled floor pack with sophisticated cell-monitoring. State-of-health, cell balance and insulation resistance are the priority checks; the flagship battery is the car's most valuable component and Hyderabad heat makes cooling performance critical for range and charge speed.
- On-board charger & DC (11 kW (opt. 22 kW) AC on-board charger / up to ~200 kW DC fast charging) — High-power charging hardware — on-board charger, HV DC-DC converter and charge-port actuator are the electrical service points; charging faults are diagnosed on XENTRY, not by parts-swapping.
Transmission & Drivetrain
- Single-speed reduction gear (EQS 450+, rear) / 4MATIC dual-motor (EQS 580) (4MATIC) — applies to All EQS variants. The EQS has no multi-ratio gearbox — each motor drives through a fixed single-speed reduction gear, so there are no shift-quality or clutch faults. The EQS 580 4MATIC distributes torque electronically between front and rear motors rather than through a transfer case. Reduction-gear oil is a sealed lifetime fill by MB; we inspect for weep and bearing noise on high-mileage cars.
- Electric all-wheel drive (front PSM motor) with rear-axle steering (4MATIC) — applies to EQS 580 4MATIC / rear-axle steering on all EQS. AWD is delivered by engaging the front motor rather than a prop-shaft. Separately, all EQS have rear-axle steering (up to 10 degrees), whose actuator and control unit need XENTRY calibration after any related work — a key EQS-specific service item verified on Star Diagnosis.
Suspension & Brakes
Suspension: AIRMATIC full air suspension with adaptive damping (ADS+) front and rear, plus rear-axle steering; the very heavy battery makes air suspension central to the EQS ride.
The EQS rides on AIRMATIC air suspension, so the number-one flagship complaint is air-strut bag leaks and compressor wear — the car sits low overnight or the ride turns harsh, typically after high mileage and accelerated by the battery weight and Hyderabad speed breakers and pot-holes. We diagnose whether it is a strut bag, the compressor, a relay or a valve block and repair only what has failed with genuine/Bilstein parts, far cheaper than a dealer full-axle swap. We also calibrate ride height and the rear-axle-steering system on XENTRY, and inspect the underbody battery guard after any impact.

Common EQS Faults & Hyderabad Pricing
| Area | Symptom | Root Cause | Fix Price (INR) |
|---|---|---|---|
| AIRMATIC suspension | Car sits low overnight, harsh ride, "raise vehicle" / level message | Air-strut bag leak, compressor wear, relay or valve-block failure (heavy battery accelerates it) | ₹40,000 – ₹1,40,000 |
| HV battery / cooling | Reduced range, slower DC charging, battery-temperature warning | Battery coolant degradation, cooling-pump wear or cell-balance drift on the large pack (aggravated by Hyderabad heat) | ₹20,000 – ₹2,50,000 |
| 12V auxiliary battery | Car will not wake / power up, Hyperscreen dead, no charging start | 12V battery failure — the EQS cannot boot the HV system on a weak 12V, a very common EV fault | ₹12,000 – ₹30,000 |

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 flagship 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 EQS no-start / dead-Hyperscreen cause.
- AIRMATIC air strut & compressor — Genuine MB / Bilstein air strut & compressor. Individual strut/compressor repair with ride-height calibration instead of a full-axle dealer swap.
- Brake fluid — MB-approved DOT 4 / DOT 4 Plus. Still needs 2-yearly changes — regen means fluid ages from moisture, and old fluid corrodes ABS/regen hardware.
- Reduction-gear oil — Genuine MB e-drive reduction-gear oil (unit-specific). Sealed lifetime fill but inspected for weep and bearing noise on high-mileage cars — no clutch or ATF service.
- Cabin / HEPA filter — Genuine MB HEPA / active-carbon cabin filter. The EQS ENERGIZING air-quality system depends on the genuine HEPA element for fine-dust and odour filtration.
Star Diagnosis (XENTRY) — EQS
Every EQS begins with a full Mercedes XENTRY / DAS high-voltage diagnostic — battery-management system (state-of-health, cell voltages and balance, insulation resistance), power electronics, front and/or rear drive units, on-board charger, DC-DC converter, thermal-management, AIRMATIC and ride-height, rear-axle steering, ESP, SAM, the MBUX Hyperscreen and the full driver-assist suite. As the most complex EQ car, it demands methodical module-by-module diagnosis. 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, AIRMATIC and rear-axle-steering calibration, and after-repair calibrations (steering-angle, camera/radar) so the car leaves fault-free.
Frequently Asked Questions — EQS
Can you service a Mercedes EQS flagship electric car in Hyderabad?
Yes. We are equipped for EVs and for flagship complexity — HV-qualified technicians, XENTRY high-voltage diagnostics, battery state-of-health and insulation testing, AIRMATIC repair, rear-axle-steering calibration and MBUX coding. The EQS needs different servicing from a petrol S-Class: no oil or spark plugs, but battery health, air suspension, regen brakes and the 12V system all need attention.
How much does an EQS service cost in Hyderabad?
A minor Service A is typically ₹18,000–₹28,000 and a major Service B ₹30,000–₹48,000 — higher than the smaller EQ cars because of the AIRMATIC, rear-axle steering and Hyperscreen checks, but with no engine oil or spark plugs. We give a fixed written quote after a free inspection, usually 35–50% below dealer pricing with genuine parts.
My EQS sits low overnight — can you fix the AIRMATIC without replacing everything?
Yes. We diagnose whether it is an air-strut bag leak, the compressor, a relay or a valve block and repair only what has failed with genuine/Bilstein parts, then recalibrate ride height on XENTRY. That is far cheaper than the dealer's full-axle strut replacement.
The Hyperscreen went blank and the car would not start — what happened?
That is a classic symptom of a weak 12V auxiliary battery. The EQS uses the 12V system to boot the high-voltage system and the Hyperscreen, so a failing 12V leaves the car dead even with a charged drive battery. We test and, if needed, fit and code a genuine MB 12V AGM battery on XENTRY.
Can you check the EQS battery health and calibrate the rear-axle steering?
Yes. On XENTRY we produce a full battery state-of-health report (cell balance, insulation resistance) and we diagnose and calibrate the rear-axle-steering actuator and control unit. Both are EQS-specific items that a general workshop cannot handle but we do routinely.
Do the brakes still need work on an electric EQS?
Yes — 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 parts, and change the brake fluid on schedule.
Is it safe to service my EQS outside the Mercedes dealership?
Absolutely. We follow Mercedes HV safety protocol, use genuine/OEM parts and full XENTRY diagnostics with SCN coding and calibration, 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 EQS service?
Yes — free pickup and drop across Gachibowli, Jubilee Hills, Banjara Hills, Hitech City, Kondapur, KPHB and the wider Hyderabad area on any service, with the discretion a flagship owner expects. Call or WhatsApp 8555824915.
Customer Reviews — Mercedes EQS
My EQS sat low overnight and the dealer quoted a fortune for full AIRMATIC struts. MPS diagnosed a single leaking strut and the compressor, repaired only those with genuine parts and recalibrated ride height on XENTRY. Saved lakhs. Discreet pickup from Jubilee Hills.
The Hyperscreen went blank and the car was dead. MPS found it was the 12V battery, not the main pack, coded a genuine one and everything came back to life. Brilliant EV knowledge and a fraction of the dealer bill. Free drop to Banjara Hills.
Wanted a proper battery health report and a rear-axle-steering warning sorted. They did a full XENTRY battery SOH report and calibrated the rear-steering after repair. Genuinely the only workshop in Hyderabad that understands this car. Highly professional.
Range had dropped in the summer and the brakes were grinding from regen. MPS checked the battery cooling and coolant, overhauled the corroded brakes with genuine parts and advised on charging. Transparent pricing and excellent service. Picked up from Hitech City.
