EPS Power Steering Module Repair — Nationwide Mail-In Service

Post it in. Get it back fixed. Drive away with steering you can trust again.

Your steering felt fine yesterday. This morning the wheel is suddenly heavy, a warning light is glowing amber on the dash, and a scan has thrown up a C-code you have never seen before. That is not a rack problem, a fluid problem, or a pump problem — because your car has an electric power steering (EPS) system with no fluid at all. The culprit is almost always the EPS control module, and the good news is that it can almost always be repaired. You do not need a main dealer. You do not need a £700 exchange unit. You need The Vehicle Check.

We are a UK automotive electronics specialist based in Enfield, EN3, and we have been diagnosing and repairing vehicle control modules — from ECUs and ABS units to airbag modules and immobilisers — for well over a decade. EPS module repair is one of the services our technicians carry out every single week, across a wide range of makes and model years. Our nationwide mail-in service means you can reach us wherever you are in the UK — Cornwall, Edinburgh, Belfast, anywhere — without leaving your driveway.

What Does an EPS Module Actually Do — and Why Does It Fail?

The EPS module is the brain of your electric power steering system. It reads signals from the torque sensor on the steering column (telling it how hard you are turning the wheel), cross-references vehicle speed from the CAN bus, and sends precise current instructions to the EPS motor to provide exactly the right level of assistance. When the module develops a fault — whether that is a failed internal MOSFET, a corrupted memory sector, a degraded capacitor, or a dry solder joint caused by years of under-bonnet heat cycling — the system either reduces assistance as a safety measure or shuts off entirely.

Common failure symptoms include:

• Sudden heavy or stiff steering with no warning beforehand
• EPS, PAS or steering warning light illuminated on the instrument cluster
• Intermittent loss of assistance that sometimes clears on restart
• Stored fault codes such as C0460, C0561, U0126, or make-specific torque-sensor codes
• Steering that works at low speed but loses assistance at higher speeds (or vice versa)

These faults are caused by component-level failures inside the module — not by the rack, the column, or the motor itself. Replacing the whole rack is an expensive and unnecessary response in the vast majority of cases.

How Does the Mail-In EPS Repair Process Work?

The process is straightforward and designed so that a competent DIY mechanic — or any local independent garage — can remove the module without specialist equipment.

1. Contact us first. Drop us a message via our contact page or call 0203 489 2610 with your vehicle make, model, year and the fault codes stored. We confirm repairability and provide a fixed price — no hidden extras.
2. Remove the EPS module. On most vehicles it is mounted on the steering column or in a bracket nearby, secured by two or three bolts and one multi-pin connector. A basic socket set is all that is usually needed. If you are unsure, a local independent garage can remove it in under an hour.
3. Package and post it safely. See our packaging tips below — proper protection during transit is the single most important step you control.
4. We diagnose and repair. Our technicians carry out a full bench diagnosis, carry out the necessary component-level repairs, then run the module through a comprehensive bench test to confirm correct operation across all input and output parameters.
5. We return it to you — free. The repaired module is dispatched back to you with free tracked return postage. Turnaround from receipt is 3–5 working days in most cases, often faster for common units we hold test rigs for.
6. Refit and reset. Refit the module, reconnect the battery, clear any stored codes with an OBD scanner, and perform a steering-angle reset if your vehicle requires one (we advise you in advance if this applies).

How Should I Package My EPS Module for Safe Posting?

Packaging it correctly takes five minutes and eliminates the only real risk in the mail-in process. Follow these steps:

• Wrap the module in at least two layers of bubble wrap, paying particular attention to any exposed connector pins. Fold the bubble wrap over the ends and secure with packing tape.
• Use a rigid cardboard box — not a padded envelope. The box should be large enough to allow at least 3–4 cm of padding material on every side.
• Fill void space with foam peanuts, scrunched newspaper, or additional bubble wrap. The module must not be able to shift inside the box during transit.
• Include a note inside the box with your name, contact number, vehicle details (make, model, year, engine), and a brief description of the fault. This speeds up our bench diagnosis and means we can contact you quickly if we have questions.
• Send it tracked. We recommend Royal Mail Special Delivery (next-day, insured) or a reputable tracked courier service. Address your parcel to: Office 13, 25 Mollison Avenue, Enfield, EN3 7NJ.

Why Does Mail-In Repair Beat the Dealer?

A main dealer's response to an EPS fault is almost always the same: replace the whole steering rack or the whole column assembly as a unit, because dealers do not carry out component-level electronics repair. That means a bill that often sits between £600 and £1,500 once parts and labour are combined. Worse, a new or exchange unit may require coding to your vehicle's VIN, torque-sensor re-calibration, and sometimes a software update — additional labour charges on top.

Our repair service costs a fraction of that. We return your original module, which already holds your vehicle's calibrated settings, significantly reducing the re-initialisation work required on refit. There is no VIN-mismatch risk, no waiting weeks for a back-ordered part, and no inflated dealer labour rate on top of an inflated parts price.

Compare that to eBay-listed repair services where the price advertised often excludes return postage, diagnostic fees are added if the fault is not instantly obvious, and warranty terms are vague or non-existent. With TVC you get a fixed price agreed before you post, free return shipping, and a warranty on the repair — full stop.

You can read more about our broader mail-in capability on our mail-in repair service page. If your vehicle has additional modules that need attention — an ECU, an ABS unit, or something else — our ECU repair and ABS module repair services run alongside the EPS repair and can often be combined in a single postal visit.

What Is TVC's Experience With Automotive Electronics?

The Vehicle Check has been repairing automotive control modules professionally for well over a decade, working on vehicles from 2004 right through to 2026 model years. Our technicians hold hands-on, component-level experience across ECUs, ABS modules, airbag control units, BCM and CEM modules, immobilisers, mechatronics, and EPS systems across European, Asian and American platforms. We are not a generic electronics repair shop that occasionally looks at a car module — automotive electronics is the entirety of what we do, every day, on a bench purpose-built for the job. That focus is the reason our repair success rate is as high as it is, and it is why customers send modules to us from across the UK rather than accepting a dealer's replacement quote.
