Hyderabad's ECM / TCM Repair Authority
Metre Per Second — Premium Car Service and Repair is Hyderabad's dedicated ECM and TCM repair workshop. While general garages simply swap a ₹40,000 control unit and re-quote, we repair the module at component level — recovering corrupted EEPROM, replacing failed driver stages and resealing water-damaged housings — and confirm the real fault on the manufacturer's own platforms (VW/Audi ODIS, Mercedes XENTRY, BMW ISTA, Hyundai/Kia GDS).
An engine control module (ECM/ECU) and a transmission control module (TCM/TCU) are dense, multi-layer circuit boards running safety-critical software. A Bosch EDC17 killed by a voltage spike, a ZF 8HP lead-frame that has cracked from heat, or a Mercedes 722.9 conductor plate weeping fluid into the connector each fail in a completely different way. Our technicians read live data, freeze frames and stored DTCs (P0700, P0606, P0604, P189C) before opening a single unit, so you only pay for the repair your car genuinely needs.
Over 10 years and 25,270+ vehicles in Hyderabad, we have built our reputation on honest diagnosis, genuine drivers and connectors, and a 1-year warranty on every module repair. Free pickup and drop across KPHB, Kukatpally, Madhapur, Gachibowli and Banjara Hills means your car reaches our diagnostic bay without you losing a day of work.
What We Repair
ZF 8HP Lead-Frame & TCU
The classic ZF 8HP P0700 'transmission malfunction' on BMW, Audi and Land Rover is almost always a cracked internal lead-frame (Bosch GS19/GS20) — we replace the mechatronic lead-frame and re-learn adaptation on ISTA/ODIS.
Mercedes 722.9 / 9G-Tronic Mechatronic
Conductor-plate failure, 13-pin connector seal leaks and 725 9G-Tronic mechatronic faults (P0894/P0741) — conductor plate replacement, connector reseal and SCN coding via XENTRY and Vediamo.
EEPROM Recovery & ECU Cloning
We extract, repair and re-write corrupted EEPROM/flash, recover immobiliser and adaptation data, and clone a unit to a known-good board when a chip is beyond saving — so the car keeps its original keys and VIN.
Immobiliser Sync & Key Coding
After a jump-start, battery failure or module swap the engine can crank-no-start from immobiliser desync — we re-sync the ECU, IMMO and key on ODIS, XENTRY, ISTA, GDS, HDS, VCDS or Autel/Lonsdor.
Water-Ingress & Connector Repair
Monsoon water ingress kills under-bonnet and footwell modules. We recover corroded boards, repair burnt pins, replace connectors and re-seal the housing — common on Mahindra, Tata and BMW/Mercedes TCUs.
Our Repair Process
- Free Pickup & Symptom Logging: We collect your car anywhere in Hyderabad, record the exact symptoms (limp mode, crank-no-start, warning lights) and confirm the ECU/TCU part numbers before any work begins.
- Full Diagnostic Scan & Live Data: We read stored DTCs, freeze frames and live data on the OEM platform (ODIS / XENTRY / ISTA / GDS) to separate a true module fault from a sensor, wiring or fluid issue.
- Power-Supply & Wiring Check: Before condemning a module we verify grounds, supply voltage, CAN communication and connector integrity — many 'dead ECU' cars are actually a corroded earth or chafed harness.
- Module Removal & Bench Inspection: The suspect ECM/TCM is removed, opened in our clean bench area, and inspected for capacitor leakage, cracked solder, blown drivers, water corrosion or a failed ZF lead-frame.
- Fixed Quote & Your Approval: You get a clear, itemised, fixed quote comparing a bench repair against a replacement unit. No work proceeds until you approve it.
- Component-Level Repair & EEPROM Work: We replace the failed driver stages, capacitors, lead-frame or conductor plate with genuine/OE-grade parts, recover EEPROM data, and reflow or re-write the processor as required.
- Coding, Adaptation & Immobiliser Sync: Back in the car we run SCN/component coding, basic-settings and transmission adaptation, and re-sync the immobiliser and keys so the car starts and shifts correctly.
- Road Test & 1-Year Warranty Handover: We road-test the car under load until shifts and fuelling are perfect, clear all codes, and hand it back with the repair explained and a 1-year warranty.
Why Metre Per Second
Component-Level Bench Repair
We fix the actual board — drivers, capacitors, lead-frames and EEPROM — instead of forcing you to buy a ₹30,000–₹60,000 replacement module you may not need.
OEM Diagnostic & Coding Tools
ODIS, XENTRY, ISTA, GDS, HDS, PIWIS and VCDS — the same platforms the dealership uses — so SCN coding, adaptation and immobiliser sync are dealer-accurate.
EEPROM & Immobiliser Expertise
We recover original immobiliser and adaptation data so your car keeps its existing keys and VIN — no expensive key-set replacement after a module repair.
Genuine Drivers & Connectors
Output drivers, lead-frames, conductor plates and connector seals from OEM suppliers (Bosch, Continental, ZF) — not generic parts that fail again in months.
Free Pickup & Drop
Doorstep collection across KPHB, Kukatpally, Madhapur, Gachibowli, Hi-Tech City, Banjara Hills and Jubilee Hills.
1-Year Warranty
Every ECM/TCM repair is backed by a 1-year unconditional warranty — proof we stand behind the work.
Why ECM / TCM Repair Is Needed — Common Causes
Voltage Spikes & Jump-Starts
A reversed jump-start, a failing alternator or a dying battery sends voltage spikes through the ECU, blowing internal driver stages and corrupting the EEPROM.
Water & Moisture Ingress
Hyderabad monsoons push water into footwell TCUs and under-bonnet ECMs, corroding the board and connector pins — a leading cause of failure on Mahindra, Tata, BMW and Mercedes.
Heat-Cracked ZF Lead-Frame
On ZF 8HP gearboxes the internal mechatronic lead-frame fatigues from heat and vibration, breaking solder joints and triggering the P0700 transmission warning.
722.9 Conductor-Plate Wear
Mercedes 722.9 conductor plates wear and the 13-pin connector seal leaks ATF into the loom, causing harsh shifts, gear-not-engaging and P0894/P0741 faults.
Capacitor & Solder Fatigue
Ageing electrolytic capacitors leak and BGA solder joints crack with thermal cycling, producing intermittent stalling, no-starts and random fault codes.
Failed Reflash / Bad Coding
An interrupted software update or a botched generic 'remap' can brick a module or wipe adaptation, leaving the car in limp mode or unable to start.
How To Avoid ECM / TCM Repair — Prevention
Maintain a Healthy Battery
Replace a weak battery and fix charging faults early — stable voltage is the single best protection for the ECM, TCM and every other control unit.
Jump-Start Correctly
Never reverse the leads and avoid jump-starting from a running high-output vehicle. A momentary spike can destroy a driver stage instantly.
Keep Modules Dry
Clear scuttle drains, fix windscreen and door-seal leaks, and address any damp footwell quickly to keep water away from footwell-mounted TCUs.
Service Transmission Fluid
Spec-correct ATF service on ZF 8HP and 722.9 boxes keeps the mechatronic cool and reduces the heat stress that cracks lead-frames and conductor plates.
Use Proper Coding Tools
Only allow software updates and remaps done on OEM-grade tools with a stable power supply — never a cheap generic flash that risks bricking the unit.
Act On Warning Lights Early
A check-engine or transmission warning is the module telling you something is wrong — an early scan often catches a sensor fault before it stresses the ECU.

Recent Repairs at Our Workshop
ZF 8HP Limp Mode Fixed Without a New Mechatronic
BMW 520d · Bosch GS19 / ZF 8HP TCU
Problem: Repeated P0700 transmission faults and harsh shifting into limp mode. A franchise had quoted a complete mechatronic unit at a very high price.
Work done: ISTA confirmed the fault was the internal lead-frame, not the valve body. We replaced the ZF 8HP lead-frame, repaired the connector, and ran a full adaptation re-learn.
Outcome: Smooth, fault-free shifting restored at well under a third of the replacement quote, delivered with a 1-year warranty. (₹26,000)
Water-Damaged ECM Recovered After Monsoon Flooding
Mahindra XUV500 · Bosch EDC17 ECM
Problem: Crank-no-start and multiple stored faults after the car waded through monsoon water. The board had visible corrosion and corroded pins.
Work done: We cleaned and recovered the corroded PCB, replaced damaged driver stages, repaired the connector pins, re-wrote the EEPROM and re-sealed the housing against further ingress.
Outcome: Original ECU brought back to life with the factory keys intact — no costly replacement module or key set required. (₹11,500)
Mercedes 722.9 Conductor Plate & Connector Reseal
Mercedes-Benz C-Class · 722.9 7G-Tronic
Problem: Harsh engagement, delayed shifts and P0894 stored. ATF had wicked up the 13-pin connector into the TCU loom.
Work done: We replaced the conductor plate, renewed the 13-pin connector and sleeve seal, flushed the affected loom, and performed SCN coding and adaptation on XENTRY.
Outcome: Crisp, factory-feel shifting restored and the fluid-migration path sealed off for good. (₹32,000)
Customer Reviews
★★★★★ Karthik Reddy, KPHB — BMW 320d
Car threw a P0700 and went into limp mode. A dealer wanted to sell me a complete mechatronic. MPS scanned it on ISTA, replaced the ZF 8HP lead-frame and re-learned the adaptation. Shifts are flawless and it cost a fraction of the quote.
★★★★★ Sandeep Varma, Kukatpally — Volkswagen Passat
After a bad jump-start my Passat wouldn't start — immobiliser desync. They synced the ECU and key on ODIS the same day instead of replacing the whole module. Genuinely knowledgeable team.
★★★★★ Naveen Kumar, Madhapur — Mahindra XUV500
Monsoon water had killed my EDC17 ECU. They recovered the corroded board, repaired the pins and re-sealed the housing. Saved me a huge replacement bill and it has been perfect since.
★★★★★ Priyanka Sharma, Gachibowli — Mercedes-Benz C-Class
Harsh shifts and a transmission warning. They found the 722.9 conductor plate and connector seal leaking, replaced both and did SCN coding on XENTRY. Drives like new. Free pickup made it effortless.
★★★★★ Rahul Joshi, Banjara Hills — Audi A4
Intermittent stalling that two garages couldn't trace. MPS opened the ECU, found leaking capacitors and cold solder joints, and bench-repaired it. Honest diagnosis and a proper warranty.
★★★★★ Vamshi Goud, Jubilee Hills — Toyota Fortuner
AT TCU was acting up after a battery change. They reset the adaptation and re-coded it instead of selling me parts. Transparent pricing and quick turnaround — exactly what I wanted.
Frequently Asked Questions
What is the difference between ECM/ECU and TCM/TCU repair?
The ECM (engine control module / ECU) runs fuelling, ignition timing and emissions; the TCM (transmission control module / TCU) controls shifting, torque-converter lockup and line pressure. We diagnose and repair both — often the symptoms overlap, so a proper scan tells us which module is actually at fault.
Can you repair my ECU instead of replacing it?
In most cases, yes. We repair at component level — failed driver stages, leaking capacitors, cracked solder, ZF lead-frames and conductor plates — and recover the EEPROM. A bench repair keeps your original keys and VIN and usually costs far less than a new unit.
My car won't start after a jump-start or battery change — is it the ECU?
Often it's an immobiliser desync rather than a dead module. We re-sync the ECU, immobiliser and key on the OEM tool (ODIS, XENTRY, ISTA, GDS, HDS) and the car starts normally — no need to replace anything.
What does the P0700 transmission warning mean?
P0700 is a generic 'transmission control system' flag that points to a TCU-stored fault. On ZF 8HP gearboxes (BMW, Audi, Land Rover) it is very commonly a cracked internal lead-frame, which we replace and re-adapt — no full gearbox needed.
How much does ECM/TCM repair cost in Hyderabad?
A diagnostic scan is ₹999 (adjusted against repair). EEPROM recovery and immobiliser sync run ₹3,500–₹8,000, Bosch EDC17/MED17 bench repairs ₹6,000–₹18,000, and ZF lead-frame or 722.9 conductor-plate work ₹15,000–₹40,000. You always get a fixed quote after inspection.
Do you use proper diagnostic and coding tools?
Yes. We use the manufacturer's own platforms — ODIS, XENTRY, ISTA, GDS, HDS, PIWIS and VCDS — plus professional bench equipment, so coding, SCN, adaptation and immobiliser sync are dealer-accurate.
Do you offer pickup and drop?
Yes, free pickup and drop across KPHB, Kukatpally, Madhapur, Gachibowli, Hi-Tech City, Banjara Hills and Jubilee Hills.
Is there a warranty on the repair?
Yes — every ECM/TCM repair is backed by a 1-year unconditional warranty.
