ABS Pump & Module Repair Service
ABS warning light on? Brakes binding, a hard pedal, or no drive to one or more callipers? Since 2007, Sinspeed has remanufactured ABS pumps and modules for all makes & models — Mercedes, Volkswagen, BMW, Audi, Vauxhall, Ford and more — saving UK drivers thousands versus dealer replacement. From as little as £150 +VAT, our full rebuilds use advanced remanufacturing and higher-than-standard-OEM components to eliminate the original design fault, not just mask it. With an unlimited-mileage lifetime warranty and plug-and-play return (no coding), we get you back on the road fast — many units turned around in 24–48 hours. Send your unit from London, Glasgow or anywhere in the UK and worldwide. Explore our most common ABS repairs below, or call 0203 815 9441 for a 60-second quote.
What the ABS Pump & Module Does
The ABS (Anti-lock Braking System) stops your wheels locking under hard or emergency braking, keeping the car steerable on wet, icy or loose surfaces. The hydraulic pump and its integrated control module (ECU) read the wheel-speed sensors and pulse brake pressure to each wheel through a block of solenoid valves. When the pump or module fails, that control is lost — which is why a faulty ABS unit is both an MOT failure and a genuine safety issue.
ABS Pump vs ABS Module: What’s the Difference?
People use the terms interchangeably, but they’re two parts of one assembly. The ABS pump is the hydraulic unit — it houses the motor and the valve block that physically move brake fluid. The ABS module is the electronic control unit (ECU) bolted to it, processing the wheel-speed signals and driving the valves. On most modern cars the two are combined into a single pump-and-module assembly, which is why a fault in either can trigger the same warning light — and why we test and rebuild the complete unit rather than guessing at one half. For a full explainer, see our guide on what an ABS pump is and how it works.
Why ABS Pumps & Modules Fail
Most ABS failures are electronic or hydraulic wear inside a sealed unit, not a simple bolt-on part:
- Cracked solder joints & internal PCB faults — years of heat cycling and vibration fracture the fine solder connections on the control board, the single most common ABS module failure.
- Pump motor wear — worn motor brushes or a seized armature cause the pump to run weakly, constantly, or not at all.
- Valve block & solenoid faults — sticking or open-circuit solenoids stop the unit metering pressure correctly. Contaminated, moisture-laden brake fluid accelerates this wear, depositing sediment in the narrow valve channels.
- Corrosion & moisture ingress — water and salt reach the connector pins and board, corroding tracks and sensor circuits, especially on units mounted low in a wheel arch or behind a bumper.
- Brake-pressure sensor faults — an internal sensor drifts out of range and trips the ABS/ESP lights.
A new replacement from the manufacturer can run into the thousands, and if the original is an inherent design fault, the new unit can fail the same way again. We don’t just replace a component — we rebuild the unit to eliminate the design weakness. Fix your ABS now.
Common ABS Symptoms & Fault Codes
Send your unit in if you have any of the following:
- ABS warning light on — often with the traction-control (TC/ESP) and brake lights together, since they share the same hardware.
- A changed brake pedal — spongy, harder to press, or pulsing under normal (non-emergency) braking; some drivers describe it as feeling “disconnected”.
- Pulling to one side under braking — a faulty solenoid can misdistribute fluid. On some vehicles (including several Vauxhall Corsa models) this appears with no warning light at all, making it especially hazardous.
- The ABS pump running constantly — even with the ignition off, often with a buzzing or humming from the engine bay; it drains the battery and can burn the motor out.
- Erratic ABS activation — the system “kicking in” during gentle braking on a dry road.
- Erratic speedometer — because the wheel-speed sensors also feed the speedo, a failing module can make it jump, under-read or (on some Ford and Vauxhall models) drop out entirely along with the odometer.
- No communication between a diagnostic scanner and the ABS module.
A professional scan will store fault codes that point to the unit. These are some of the codes we see most often across UK vehicles:
| Fault code | Common vehicle | Likely cause |
|---|
| C0110 / C0200 | Vauxhall Astra J | ABS pump motor circuit / valve fault |
| C1288 | Ford Focus / C-Max | Pressure transducer failure |
| 01130 / 01435 | VW, Audi, Seat, Skoda | ABS operation implausible signal |
| ABS 51-1 / 53-1 / 37-1 | BMW E-series | Internal ABS module failure |
| U0121 | Multiple manufacturers | Lost communication with ABS module |
| C0035 / C0040 | GM / Vauxhall platform | Wheel speed sensor circuit fault |
A stored code tells you which circuit has reported a fault — not always which component has physically failed. We confirm the true root cause on dedicated test rigs before any repair is carried out.
ABS Wheel Speed Sensor Faults
Not every ABS light is the pump or module. The wheel-speed sensors feed the module, and a single failed sensor or a damaged reluctor (tone) ring will light the same warning — and sensor failure is more common than pump failure. The difference matters for cost: a sensor is usually a quick fix at roughly £50–£150 per sensor, whereas a pump or module fault needs specialist remanufacturing. Three ways to tell them apart before you send anything in:
- The code is specific. A sensor fault references a particular wheel (e.g. “left rear wheel speed sensor”); a pump/module fault references the hydraulic unit, motor circuit or valve solenoids.
- Check the wiring. Sensor cables are exposed and prone to fraying, corrosion and impact damage at each wheel.
- Read the symptom pattern. Pure sensor faults rarely change pedal feel — so an uneven pedal, pulling under braking or a constantly-running pump points to the unit itself.
If you’re not sure which you have, our guide on how to diagnose an ABS wheel-speed sensor walks through the checks — and if the code points at the unit, send it to us for rebuild.
Our ABS Rebuild & Refurbishment Process
Every unit goes through the same full refurbishment, not a quick part swap:
- Book online or call for a quote.
- Have a garage or competent mechanic remove the unit; note any stored fault codes first, and tape or plug the hydraulic ports before packing so no fluid leaks in transit.
- Send your ABS unit to our UK facility on a tracked courier.
- We strip the unit down and test it at component level on rigs that simulate real vehicle conditions, to find the true root cause.
- We rebuild it with components that meet or exceed OE specification, correcting the original design fault.
- Your unit comes back plug-and-play — no coding — usually in 24–48 hours; your garage simply refits, bleeds the brakes and clears any residual codes.
Every ABS pump repair and module refurbishment includes the full strip-down and diagnosis, a component-level rebuild, rig testing under simulated driving conditions, tracked return shipping, and an unlimited-mileage lifetime warranty. No hidden fees, no surprises, and the repair is MOT-compliant.
ABS Repair vs Replacement
A dealer will normally replace the whole unit — typically £800–£2,500 +VAT, plus programming. An ABS pump repair or module refurbishment with us starts from £150 +VAT, keeps your original matched unit, and removes the fault for good rather than reintroducing it. Because we return the same unit fully rebuilt, there’s no coding or pairing to pay for. A used scrapyard unit looks cheaper but carries the same age-related wear, rarely comes tested, and usually still needs coding — we regularly see failed second-hand units arrive having been fitted only months earlier. For most UK drivers, refurbishment is the faster, safer and far cheaper route back to a MOT-ready car; the only time a new unit wins is genuine physical damage, such as a cracked hydraulic block from a collision.
What Affects the Cost of an ABS Repair
A safety-critical repair done to a poor standard is a false economy whatever the price, so it’s worth understanding what drives a quote before comparing:
| Factor | Why it matters |
|---|
| Vehicle make and model | Less common or premium vehicles can need harder-to-source components and longer diagnosis on specialist rigs. |
| ABS unit generation and complexity | A standalone unit costs less to remanufacture than one integrated with traction control, ESP or brake assist — more internal components, more potential failure points. |
| Extent of internal damage | Electronic and hydraulic faults are quicker to resolve than physical damage, such as a unit from an accident-damaged vehicle. |
| Whether recoding is required | We return your original unit, so no dealer coding visit is needed in the vast majority of cases — a new or exchange unit almost always adds coding cost. |
| Parts availability | Older or discontinued units can take longer to source internal parts for; we hold extensive stock, but some rare units need lead time. |
| Warranty and testing standard | A reputable remanufacturer rig-tests every unit and backs it with a meaningful warranty; skipping that is a false economy on a braking component. |
The most accurate way to get a figure is to send us your registration and ABS unit part number with the fault codes and a description of the symptoms. What we can say with confidence: remanufacturing your original unit is typically up to 90% cheaper than a new dealer unit, with no coding costs on return in most applications, and every repair carries a lifetime warranty.

Older & Obsolete ABS Units
On many older vehicles a brand-new ABS pump or module is discontinued, superseded or on long back-order from the manufacturer — sometimes with no replacement available at all. Because we rebuild your original unit rather than supplying a new one, a refurbishment is often the only practical way to keep an older car on the road. It also sidesteps the supply delays and obsolescence that come with chasing a new part, and because the rebuilt unit is your own matched assembly, it goes straight back on with no coding or pairing.
Units & Systems We Rebuild
Our workshops see the major ABS platforms in for rebuild and exchange daily, including:
- Bosch ABS/ESP units (5.3, 5.7, 8.0 and later) — common across VW Group, BMW, Vauxhall and PSA
- ATE / Teves Mk60, Mk70 and Mk100 units — common on Mercedes, MINI, Renault and Nissan
- TRW and Continental ABS/ESP modules — common on Ford, Land Rover and Jaguar

Frequently Asked Questions
Q: Can an ABS pump be repaired? A: Yes. Most ABS pumps and modules can be remanufactured to fix faults like a stuck pump motor, cracked solder joints or a brake-pressure-sensor fault, saving up to 90% versus a new unit. Our rebuilds correct the root cause for a lasting result.
Q: Is ABS refurbishment as good as a new unit? A: Done properly, it’s better for the known fault — we rebuild your original matched unit with components that meet or exceed OE spec, so the design weakness that caused the failure is removed, and it returns plug-and-play with a lifetime warranty.
Q: How do I know if it’s the ABS pump or a wheel-speed sensor? A: A sensor fault usually references a specific wheel position and rarely changes the brake pedal feel; a pump or module fault references the hydraulic unit, motor or valves and often comes with pedal or braking changes. A professional scan confirms which — many generic code readers can’t talk to the ABS module at all.
Q: Can you repair a Bosch or ATE/Teves ABS unit? A: Yes — Bosch (5.3/5.7/8.0) and ATE/Teves (Mk60/Mk70/Mk100) are the platforms we see most, alongside TRW and Continental. Send us the part number and we’ll confirm the repair.
Q: My ABS module won’t communicate with the scanner — can you fix it? A: Usually, yes. A “no communication” fault is often a cracked solder joint or a failed internal driver on the control board, which we repair at component level so the module talks to your diagnostics again.
Q: My ABS pump runs constantly and drains the battery — is that repairable? A: Yes, and we see it regularly. A continuously running pump is a known failure mode from an internal relay or ECU fault that energises the motor when it shouldn’t. Left alone it flattens the battery and eventually burns out the motor, so it’s worth addressing promptly.
Q: Can I drive with a faulty ABS pump? A: It’s risky. An ABS fault can cause brake binding or longer stopping distances and will fail an MOT. Send your unit in for a fast fix to stay safe and road-legal.
Q: Will my car pass its MOT after the repair? A: Yes — a correctly working ABS clears the warning light and meets the MOT brake checks. We rig-test every unit before return so it goes back road-legal and safe.
Q: How much is an ABS repair? A: Repairs start from as little as £150 +VAT, compared with £800–£2,500 +VAT at a dealer. That includes a full rebuild, rig testing and a lifetime warranty.
Q: Do I need coding or programming? A: No. Because we return your own rebuilt unit, it’s plug-and-play straight out of the box — no expensive programming fees.
Q: How long does it take? A: Many units are turned around in 24–48 hours once they reach us, plus tracked return shipping.
