Fuel injector repair – cleaning, rebuilding, replacing
Fuel injectors are the most precision-engineered component in your car — and the most punished. Modern Common-Rail Diesel (CRDi) injectors operate at 2,000+ bar pressure, fire 5+ times per combustion cycle, and tolerate dirt particles measured in microns. When they wear, the symptoms cascade fast: black smoke → DPF clogging → turbo stress → catalytic converter failure → expensive repair. At MPS we offer three levels of injector service: ULTRASONIC CLEANING (₹1,500-3,500/injector — restores 70-90% of original flow when caught early); FULL REBUILD (₹3,500-12,000/injector — new nozzles, return valves, O-rings, full flow-bench test, OEM coding); and REPLACEMENT (only when rebuild can't restore spec — saves 60-70% vs new sets). We service Bosch CRI2/CRI3 piezo (most German + Indian diesels), Denso G3S/G4S piezo (Toyota GD-series), Delphi DFI (Mercedes OM651), Continental HDEV5/6 GDi (BMW N20/B48, Audi EA888), and standard MPI petrol injectors. Every job ends with a flow-bench test report you can keep.
Warning signs to watch for
| Symptom | What it usually means |
|---|---|
| Black smoke under acceleration (diesel) | Classic injector dribble or stuck-open. Excess fuel = DPF clog + turbo damage if ignored. |
| Hard cold start, extended cranking | Leaking injector return valves bleed pressure overnight. 2-hour fix prevents fuel pump failure. |
| Misfire codes P0201–P0204 | Specific cylinder injector failure. Each digit = the bad cylinder. Diagnostic confirms before replacement. |
| Tractor-like diesel knock when warm | Worn injector piezo crystal causing late or excess injection. Re-coding and rebuild restores quiet running. |
| Long crank time, then runs rough at idle | Petrol injector clogged orifices or sticking. Ultrasonic clean usually fixes it for ₹1,500. |
| Power loss / limp mode + P0089 / P02CD codes | Fuel pressure regulation issue caused by leaking injector. OEM tool scan + flow test diagnoses fast. |
Why it fails in Hyderabad conditions
Poor fuel quality
Diesel sulphur and water content vary widely in Hyderabad. Even Bharat Stage VI fuel can carry contaminants that wear injector nozzles 30-50% faster.
Carbon build-up (GDi engines)
Direct-injection petrol engines (TFSI, T-GDi, GDi) accumulate carbon on intake valves & injector tips because no fuel washes them. Walnut blasting is mandatory at 60K km.
Skipped fuel filter changes
Diesel fuel filters MUST be changed every 30-40K km. A clogged filter starves injectors and forces them to operate at extreme pressures.
DPF + EGR cascade
A clogging DPF raises back-pressure → forces injectors to compensate with longer pulses → accelerates injector wear → causes more soot → DPF clogs faster. Breaking the cycle requires fixing injectors first.
Our process
- OEM diagnostic scan: ISTA, XENTRY, ODIS or IDS5 scan to read injector-specific codes, pulse correction values and pilot injection adaptations. Identifies which injectors are actually faulty.
- Removal + bench inspection: Injectors removed, copper washers and seal kits photographed for your records. Visual inspection of nozzle tips and electrical resistance check of solenoid/piezo.
- Flow-bench testing & rebuild: Each injector tested on a Bosch flow bench at 4 stages (idle, mid-load, full-load, leak-back). New nozzles, return valves and seals fitted. Re-tested until spray pattern matches OEM spec.
- Refit + coding + road test: Refitted with new copper washers, torqued to OEM spec. New IMA/Q-codes programmed via OEM tool. Adaptations reset. 30-km road test before handover with flow-test report.
Fuel Injector Repair pricing
| Job | Price | Details |
|---|---|---|
| Ultrasonic injector cleaning | ₹1,500 – ₹3,500 / inj | Best for petrol MPI and early-stage diesel injector clogging. Restores 70-90% of flow. |
| Full injector rebuild | ₹3,500 – ₹12,000 / inj | New nozzle, return valve, O-rings, flow-bench test, OEM coding. Diesel CRDi standard. |
| Bosch CRDI rebuild (4-cyl set) | ₹15,000 – ₹48,000 | Full set rebuild with flow-bench report. Includes copper washers and adaptation. |
| GDi walnut blasting (intake clean) | ₹6,500 – ₹18,000 | Mandatory at 60K km for direct-injection petrol (TFSI/T-GDi/GDi). Restores 8-12% lost power. |
| Injector replacement (per piece) | ₹8,000 – ₹35,000 | When rebuild cannot restore spec. OE or OEM-equivalent. Warranty included. |

Why Shamshabad drivers choose Metre Per Second
- Bosch flow bench on-site — We are one of few Hyderabad workshops with a Bosch / Hartridge flow bench — the same equipment Bosch's own service centres use.
- All major brands — Bosch CRI2/CRI3, Denso G3S/G4S, Delphi DFI 1.5, Continental HDEV5/6, Magneti Marelli, Siemens VDO. We rebuild what others quote replacement for.
- OEM coding capability — Toyota Q-codes, BMW IMA codes, Mercedes XENTRY adaptation, Audi/VW ODIS adaptation. New injector ≠ working injector unless coded properly.
- Save 60-70% vs new — A new luxury car injector set can cost ₹2-3 lakh. Our rebuild brings it back to spec for 30% of that, with 6-month warranty.
Frequently asked questions
Do you offer fuel injector repair pickup from Shamshabad?
Yes. Free pickup and drop is included for Shamshabad — our driver collects your car from anywhere near RGIA Airport / Shamshabad and returns it after the work. Shamshabad is about 28 km (45-55 mins) from our KPHB workshop.
How much does fuel injector repair cost for Shamshabad car owners?
Typical jobs run 1500 to 85000 depending on the car and fault. Every job starts with a written estimate — parts, labour and taxes listed separately — approved by you before work begins.
Is there a warranty on fuel injector repair?
Yes — every fuel injector repair job carries a 1-year warranty on parts and labour, backed by our KPHB workshop serving Shamshabad and all of South Hyderabad.
How much does fuel injector cleaning / repair cost in Hyderabad?
Ultrasonic cleaning is ₹1,500-3,500 per injector. Full rebuild (new nozzle + return valve + flow test + coding) is ₹3,500-12,000 per injector depending on brand. A complete 4-cylinder Bosch CRDI set rebuild typically costs ₹15,000-48,000. Walnut blasting (for direct-injection petrol intake carbon) is ₹6,500-18,000. We give a fixed-price quote after diagnostic.
Can clogged injectors be cleaned, or do they need replacement?
90% of injector problems can be fixed with cleaning or rebuild — replacement is rarely the right first answer. Ultrasonic cleaning works for early-stage issues. Full rebuild (with new nozzles and return valves) restores 95%+ of original spec. Replacement is only needed if the injector body is cracked, the piezo crystal is dead, or the solenoid coil has burned out.
Should I replace all injectors at once or just the bad one?
On modern common-rail diesel and GDi petrol engines, we recommend doing all injectors as a set if any one has failed and you're past 80,000 km. The other injectors are usually within 10-15% of failing, and the engine ECU expects matched flow rates across cylinders. Mixing old and new causes uneven combustion and shortens new-injector life.
Do you do injector coding for BMW, Mercedes, Audi?
Yes — we have ISTA (BMW), XENTRY/Star Diagnosis (Mercedes), and ODIS (Audi/VW). Every new or rebuilt injector requires injector coding (called IMA on BMW, Q-codes on Toyota, XENTRY adaptation on Mercedes). We code, write the values to the ECU and reset adaptations as part of the service. Many workshops skip this step — and the engine runs poorly as a result.
