Car symptom checker

What is your car telling you?

Pick the symptom closest to what you are noticing. We show the most common causes, how urgent it is and what to book.

This guide is for information only – a proper inspection is the only way to confirm the fault.

How it works

From the first message to the chequered flag

A clear four-step process, so you always know where your car is, what it needs and what it will cost.

  1. 01

    Call or WhatsApp

    Tell us the car and the problem. Book online, call or send a WhatsApp – a short video of the noise or warning light helps a lot.

  2. 02

    Scan & inspect

    We scan every system and inspect the car properly, so we find the real fault instead of guessing with parts.

  3. 03

    Quote first

    You get an itemised quote as a PDF on WhatsApp or email – parts and labour shown separately. Nothing starts without your OK.

  4. 04

    Fixed & road tested

    We repair, road test and hand the car back with a clear invoice and our workmanship guarantee.

Good to know

Questions drivers ask us

Straight answers about engine overhauls, quotes, parts, warranties and payment.

All FAQs

All makes and models – Toyota, Volkswagen, Nissan, Ford, Hyundai, Kia and the Chinese brands, right up to Mercedes-Benz, BMW and Audi – plus bakkies and light commercial vehicles, petrol and diesel.

It depends on the engine and what we find inside it. We start with a diagnosis (compression test, scan and inspection) and give you a ballpark figure. After strip-down and measuring, you get a written quote for the parts and machining actually needed – nothing extra is fitted without your approval.

Most overhauls take one to two weeks, depending on machining and parts availability. We keep you updated on WhatsApp with photos as the rebuild progresses.

A diagnostic scan and a check of brakes, tyres, suspension and steering, battery and charging, belts, hoses, leaks, fluid levels, lights and wipers. You get a written report and a quote for anything that should be fixed before your trip.

Yes. Replacement injectors – and injectors moved between cylinders – must be coded to the engine computer on most modern diesels and direct-injection petrol engines. We test, replace and code injectors on all brands.
