ABS pump relay stuck on.
C1214 — also written C1214, C 1214, 1214 — is the OBD-II code for brake control relay circuit always active. Same code, same fix: this page covers every spelling of it.
This code means your ABS pump's internal relay has welded itself shut, meaning the pump is getting power when it shouldn't. It's a classic headache on mid-2000s Vauxhalls and Nissans.
C1214 is a electrical fault code, typically costing £150–£1200 to put right in a UK garage.
What C1214 actually feels like to drive
- The ABS pump motor keeps humming even after you’ve pulled the key out of the ignition.
- Battery goes flat overnight because the pump relay is drawing power 24/7.
- Brake pedal feels 'wooden' or lacks that initial bite when you first set off.
- ABS and Traction Control lights glowing steady on the dash from cold start.
- A distinct 'whirring' noise coming from the passenger side bulkhead area.

The C1214 misdiagnosis that wastes money
I’ve seen dozens of lads waste time and money swapping out wheel speed sensors or brake light switches just because the ABS light is on. On these units, especially the older ATE or Bosch blocks, C1214 is almost always internal. They buy a £20 sensor off eBay, it doesn't work, then they try a second-hand relay from a breakers that’s just as knackered as the one they’ve got. The actual fault is usually a tiny internal weld in the ABS control module that’s failed or a stuck solenoid coil, not the bits bolted to the wheels.
What a UK garage should charge for C1214
If it’s just a simple external relay, you’re looking at £40 for the part and 30 mins labour. But 90% of the time, it's the module. A UK independent will charge about £60-£90 for the initial diagnostic. A rebuild of your own unit via a specialist is usually £200-£250, plus 2-3 hours labour (£150-£200) to R&R and bleed the brakes with fresh DOT4. A brand new unit from a main dealer like Arnold Clark? You won't get much change from £1,200 including the coding.
C1214 repair cost in the UK
Most C1214 repairs land between £150–£1200 including parts and labour. The spread is wide because the cheap fix (a sensor, a hose, a leak) and the expensive fix (a major component) throw the same code — which is why a proper diagnosis before parts are bought saves the most money.
Bob's tip on C1214
If your garage tells you that you need a brand-new ABS pump from the main dealer, they’re probably trying to save themselves the hassle, but it’ll cost you a grand. Ask them, "Can we send my original module to a UK specialist like ECU Testing or BBA-Reman?" It’s a fraction of the price, you get a lifetime warranty, and crucially, you don't have to pay a dealer to 'code' the new unit to the car’s VIN because it’s your original part. It’s the difference between a £300 bill and a £1200 one.
