FAQ

Common symptoms include:

• Heavy steering
• Intermittent loss of power steering
• Warning light on the dashboard
• Unusual whining or buzzing noises
• Steering assistance that works only occasionally

Yes. Most EHPS pumps can be professionally repaired or remanufactured unless they have suffered severe mechanical damage or extensive corrosion.

n many cases, yes. A professionally repaired EHPS pump is often more cost-effective than buying a new unit while providing comparable reliability when quality components and proper testing are used.

The most common causes include:

• Worn bearings
• Electric motor failure
• Electronic control unit (ECU) faults
• Water ingress
• Low battery voltage
• Corroded electrical connectors
• Internal hydraulic wear

Yes. Low system voltage forces the electric motor to operate under higher load, which may overheat the electronics and shorten the pump’s lifespan.

Yes. We repair or replace faulty electronic components, including damaged control boards, power transistors, relays, and other electronic parts whenever possible.

Absolutely. Every repaired EHPS pump is tested on professional equipment to verify hydraulic pressure, flow rate, electrical performance, and overall functionality before it is returned.

Most repairs are completed within 2–4 working days after receiving the pump, depending on the fault and parts availability.

Drain any remaining hydraulic fluid, protect all hydraulic ports, wrap the pump securely with cushioning material, and pack it in a strong cardboard box to prevent damage during transport.

We repair EHPS pumps used in many European and Asian vehicles, including Opel, Volkswagen, Audi, Škoda, Seat, Peugeot, Citroën, Ford, MINI, Fiat, Toyota and others.

In many cases, yes. The sooner the pump is inspected after water exposure, the greater the chance of a successful repair.

Yes. Proper bleeding is essential to remove trapped air from the hydraulic system and ensure smooth, quiet steering operation.

Yes. Fresh hydraulic fluid is always recommended after installing a repaired or replacement EHPS pump to maximise service life.

Intermittent heavy steering is commonly caused by failing electronics, poor electrical connections, unstable voltage, or an overheating electric motor.

Diagnostic Trouble Codes (DTCs) provide valuable information but should always be confirmed with electrical and hydraulic testing before replacing the pump.

Yes. Insufficient charging voltage can cause the pump to malfunction, generate fault codes, or stop operating completely.

Yes. Worn bearings and seals are replaced whenever necessary to restore reliability and prevent future leaks or mechanical failures.

Yes. Excessive noise is often caused by worn bearings, cavitation, contaminated fluid, or internal hydraulic wear, all of which can usually be repaired.

Unfortunately not. Pumps with severe mechanical damage, cracked housings, or irreparable electronic failure may not be economically repairable.

A professional diagnosis should include electrical testing, hydraulic pressure measurement, and inspection of the steering rack before replacing any components.

All professionally repaired pumps are covered by a 24 months warranty in accordance with our warranty terms and conditions.

Possible causes include stored fault codes, damaged wiring, incorrect installation, steering angle sensor faults, or problems elsewhere in the vehicle’s electrical system.

Some types of pumps come with different control unit codings, so we recommend contacting us before ordering and we will be happy to advise you.

If you have the appropriate tools and experience, yes. However, professional installation is recommended to ensure correct bleeding, electrical connection, and system operation.

Contaminated fluid can quickly damage a repaired pump. The hydraulic system should always be flushed and filled with new, specified oil before installing a repaired unit.

We repair many major EHPS pump brands, including TRW, KOYO, JTEKT and several OEM manufacturers, subject to parts availability.

Professional repair includes complete diagnostics, replacement of worn components, functional testing, and quality control—helping ensure reliable performance and a longer service life.

Yes. We accept EHPS pumps from customers across Europe and can arrange return shipping after repair.

Simply contact us by phone or email with your vehicle details and pump part number. We’ll guide you through the shipping process, inspect the unit, provide a quotation, and complete the repair once approved.
