Stuck job? Send it to PK.

More than 100 garages and dealers in the region already send us the work they can’t finish. We fix it, report back and hand it back to you.

What garages send us

The jobs that eat a ramp for a week

  • 01

    Diagnostics you can’t get to the bottom of

    Intermittent faults, CAN bus and network faults, wiring and module communication problems. Dealer-level tools and the experience to read them.

  • 02

    ECU test and repair

    Engine and other control units tested and repaired in-house, often at a fraction of the cost of a new unit from the manufacturer.

  • 03

    Seized injectors and broken glow plugs

    Extracted in the vehicle with specialist hydraulic tools, or send us the cylinder head on its own.

  • 04

    Injector testing and coding

    Bench testing to show which injectors have actually failed, cleaning and coding to the ECU.

  • 05

    Key coding and immobilisers

    Key programming and immobiliser faults across most makes.

  • 06

    Rolling-road time

    Our all-wheel-drive dyno to reproduce faults under load, or to verify power for your customer.

How it works

Simple for you, quick for your customer

  1. 01

    Ring or email with the details

    Registration, the symptoms, any codes and what has already been checked or replaced.

  2. 02

    Bring it in or send the part

    Drop the vehicle off, or send the unit or cylinder head on its own.

  3. 03

    We report back

    You hear what we found and the cost before any repair, so you can quote your customer.

  4. 04

    Back to you

    Repaired and tested, with notes you can pass to your customer.

Draft Trade terms, account set-up, turnaround times and collection options to be confirmed with PK. The old site had no trade page at all.

Examples

Trade jobs from the workshop

  • Diagnostics November 2016

    Car with CAN bus failure codes

    Every module blamed the engine ECU. The ECU was fine.

    In
    Other control units were reporting a CAN failure of the engine ECU.
    Found
    Checking the CAN bus signals showed the engine ECU was working. The fault was in the wiring to the body control module.
  • Diesel December 2014

    Vauxhall Vivaro

    Four seized injectors out of a Vauxhall Vivaro

    In
    Injectors seized in the cylinder head: a common problem on these engines. One had already had its top threads stripped.
    Found
    Severe corrosion. Injector 1 had snapped at an unusual point; injector 2 snapped leaving its cap in the head.
  • Tuning October 2016

    2013 Audi TT

    Damaged ECU repaired, then remapped

    In
    Someone else had already attempted to work on the ECU.
    Found
    The ECU could not be read until it was repaired.

Training

Lincoln Training Academy

PK’s sister business, opened in 2021, trains motor vehicle technicians. If your team needs skills as well as a fix, ask about courses.

Why garages call

“Checking CAN bus signals from the engine ECU as other computers report a CAN failure of the engine ECU. Obviously not the case. Don’t believe all you read from the diagnostic machine.”
