Intercooler Cleaning, Pressure Test & Repair in Hyderabad
Air-to-air & air-to-water charge coolers · oil-soaked intercooler ultrasonic clean · charge-air pipe & coupler replacement
Metre Per Second is Hyderabad's specialist workshop for intercooler cleaning, pressure-testing and repair. The intercooler (a.k.a. charge-air cooler) is one of the most ignored components on a turbocharged engine — and in Hyderabad's heat and dust, it is also one of the most neglected. Over time, oil mist from the turbocharger PCV / crankcase ventilation system collects inside the intercooler core, lining the internal fins with a thick varnish that destroys cooling efficiency. The result: higher intake-air temperatures, knock retard, loss of power, increased fuel consumption, EGT spikes and accelerated turbo wear. On modern direct-injection engines this is even worse because the oily intake air feeds carbon directly onto the intake valves. We service both air-to-air intercoolers (most diesels and older petrol turbos) and air-to-water charge-air coolers (BMW B-series N20/N55/B58, Mercedes M139 / M256, Audi 3.0T EA839, Porsche Macan / Cayenne, S4/S5/S6 V6 turbo, etc.). Our process: visual inspection, full pressure test at 25-30 psi to confirm core integrity, removal, ultrasonic clean of the core (alkaline degreaser at 60°C), inspection of every weld and end-tank, replacement of EPDM hoses, silicone couplers and T-bolt clamps as needed, refit and post-fit pressure recheck. For air-to-water charge coolers we also test the auxiliary water pump, the secondary radiator and the LT coolant for contamination. Most jobs are completed in 1-2 days with 1-year warranty.
Common Intercooler Service Problems We Fix
Oil-Soaked Intercooler Core
Internal intercooler fins coated with oil varnish from PCV / blow-by
Symptoms:
- Loss of power especially on hot days
- Higher fuel consumption
- Knock retard / pinging on premium fuel
- Oil pooling visible at intercooler outlet
Solution: Intercooler removal, ultrasonic alkaline clean of the core, PCV / oil-separator inspection, replace silicone couplers
Cracked Intercooler End-Tank
Plastic end-tank or weld develops a crack causing boost leak
Symptoms:
- Hissing under boost
- Slow boost build
- Visible crack on plastic end-tank
- Limp mode on hard acceleration
Solution: End-tank replacement (where available) or full intercooler replacement with OEM or upgraded all-aluminium unit
Charge-Pipe / Coupler Failure
Cracked TFSI / N54 charge pipe or split silicone coupler
Symptoms:
- Loud whoosh under boost
- Sudden loss of power
- Boost pressure DTC (P0299 / P00BD)
- Coupler visibly off the intercooler outlet
Solution: Replace cracked plastic charge pipe with aluminium upgrade or genuine OEM, replace EPDM coupler with silicone, new T-bolt clamps
Air-to-Water Charge Cooler Pump Failure
Auxiliary LT coolant pump for the air-to-water IAT system fails
Symptoms:
- "Reduced engine power" message after sustained hard driving
- IAT spikes seen on diagnostic tool
- Whining auxiliary pump or no pump operation
Solution: LT coolant pump replacement, secondary radiator flush, top up with correct LT coolant, bleed system
Our Diagnostic & Repair Process
- Visual & Underbonnet Inspection: Inspect intercooler, charge pipes, couplers and front of car for oil deposits, road-debris damage and missing clamps
- Boost Leak Smoke Test: Pressurise the entire intake tract from turbo outlet to intake manifold with smoke at 15-20 psi to find leaks
- Live Data IAT Logging: Datalog intake air temp before vs after intercooler under load to quantify cooling efficiency drop
- Removal & Internal Inspection: Remove intercooler, drain residual oil, inspect core fins for damage, weigh oil collected to assess severity
- Ultrasonic Clean & Refit: Ultrasonic alkaline degreaser at 60°C, dry, refit with new EPDM/silicone couplers and T-bolt clamps, post-fit pressure test

Frequently Asked Questions — Intercooler Service in Hyderabad
How often should I clean my intercooler?
Most modern turbo engines benefit from an intercooler clean every 60,000-80,000 km, sooner if you have a worn turbo seal or a failed PCV system. Direct-injection turbos (BMW N20/N55/B58, VW EA888, Mercedes M270/M133) tend to oil up faster and benefit from cleaning at every 50,000 km along with intake valve walnut blasting.
Will a clean intercooler give me more power?
It will restore lost power. A heavily oiled intercooler can lose 8-15% of cooling efficiency, which the ECU compensates for by retarding ignition timing on petrol or de-rating boost on diesel. After cleaning, the car typically feels back to factory performance — not "more than stock."
My charge pipe cracked — should I upgrade to aluminium?
On the BMW N54 / N55 / N20 and VW TFSI engines the OEM plastic charge pipe is a known failure point. We strongly recommend an aluminium replacement — the part cost is similar and the upgrade is permanent. On other engines, OEM plastic is fine.
Do you service air-to-water charge coolers (BMW B58, Mercedes M139)?
Yes. Air-to-water systems require an additional LT coolant circuit check, auxiliary pump test and secondary radiator flush. We have the OEM tools for BMW (ISTA) and Mercedes (Star) to commission the system after repair.
Customer Reviews — Intercooler Cleaning & Repair in Hyderabad
Lost noticeable power above 4500 rpm and IAT was reading 60°C+ on hot days. MPS pulled the air-to-water charge cooler, ultrasonically cleaned a frankly disgusting amount of oil out, replaced the LT pump and refilled the secondary coolant. Power is back, IATs hold steady at 35°C even in traffic.
Cracked plastic OEM charge pipe on the S4 — Audi quoted ₹52,000 for another plastic one that'll fail again. Metre Per Second installed a Forge aluminium upgrade pipe and silicone couplers for ₹28,000. Boost is rock solid and it's a permanent fix.
Intercooler was so oil-soaked it was pooling on the underbody splash guard. MPS cleaned the front-mount intercooler, replaced the PCV catch can and silicone couplers. They told me upfront the PCV was the root cause — fixed it properly. Pickup is much sharper.
After 30,000 km of spirited driving the IAT was creeping up. MPS removed and cleaned the side-mount cooler on the M139, flushed the LT coolant circuit and pressure-tested the whole system. AMG performance is back. They know these turbo platforms inside out.
