Computer diagnostics
We read the stored fault codes in every control unit, including the ones that have not lit a dashboard light yet, and we can tell when a memory was cleared recently. Japanese, Korean, Chinese, French, German and American makes.
Guarantee Car Service inspects used and brand-new cars and hands you a written report covering every part of the car, prepared by engineers trained on both modern and older models, so the decision to buy is made on facts rather than on what the seller says.
If you want someone with real experience beside you while you buy, you are in the right place. Call us now and a car inspection engineer will come to the car and tell you exactly what condition it is in.
A computer car inspection is one of the things anyone about to buy a car should insist on. Inspecting a car before you buy it, a used one above all, is what protects you from the problems that surface later because a seller kept quiet.
This is where a specialist car diagnostics centre comes in. Guarantee Car Service runs the latest diagnostic equipment, used by engineers who do this work every day rather than as a sideline.
We work on more than 115 different models. Below are some of the faults our equipment picks up, and you receive all of them written out in a detailed report, with nothing left vague.
A car inspection here is split into six separate checks, each with its own equipment, and each result is written into the report with its condition beside it.

Paint thickness is measured panel by panel, and the chassis is checked at the original weld points for signs of accident repair, cutting or pulling. This is the part a test drive will never show you.
The full check before you pay: structure, engine, gearbox, paint and odometer, with every finding written down so you can decide whether to buy and what to negotiate on.
Oil, coolant, brake and transmission fluid levels and condition, plus every filter. Neglect shows here before it shows anywhere else.
Four shock absorbers, steering rack, alignment, engine mounts, bushings and tyre condition. Cairo roads are hard on all of it.
Compression testing and a full engine check, cold and warm, with proper equipment rather than a mechanic listening at the bonnet.
The car inspection runs the same four steps whether you drive the car to our Nasr City centre or the engineer travels to wherever it is.
Tell us the make, the model year, and where the car is right now. We answer every day during opening hours.
Bring the car to our Nasr City centre, or have the engineer travel to it if it is with the seller.
Computer diagnostics, chassis and body, engine, suspension, fluids and filters, and every electrical feature.
You get every finding in writing, so you can decide whether to buy and what to negotiate on.
Whichever suits you: drive the car over to us, or have the engineer come to wherever it is.
Full equipment on site, open every day from 12 noon to 12 midnight. Drive the car over and wait for the report.
If the car is with the seller or anywhere else, our engineer travels to it and runs the full inspection there.
There is no single price for every car, and that is not a way of dodging the question: the diagnostic equipment itself differs from one car to the next. Three things set the price:
No pressure and no rough guesses. Tell us these three things and you get the price on the same call:
And if the price does not suit you, there is nothing to commit to.
Guarantee Car Service does not stop at computer diagnostics before you buy. Alongside the inspection we offer a set of other services our customers regularly need.
We repair accident-damaged cars of every make at our own workshop, at prices that stay reasonable for the amount of work involved.

Six separate inspections in one visit: a computer scan of every control unit, chassis and paint, engine and compression, gearbox, suspension and brakes, and fluids and filters. Each one is carried out with its own equipment, and each result is written into the report with its condition next to it.
A mechanic earns money from repairs, so a fault found is work won. We earn money from the inspection and nothing else, and we neither sell cars nor repair them. That is the whole reason the report is worth reading.
Yes, and most of our work is done that way. The engineer travels to the car anywhere in Cairo, Giza or Greater Cairo with the full kit. The seller does not have to hand the car over to anyone.
Around half an hour from the moment the engineer reaches the car. You are welcome to stand with him and ask about anything while it happens.
Every checkpoint with its reading, the fault codes pulled from each control unit, measured paint thickness panel by panel, the condition of the chassis at the original weld points, and a plain summary of what it all means for the price.
Yes. Zero-kilometre cars turn up with transport damage, repainted panels and factory faults more often than buyers expect, and the moment you sign for the car the problem becomes yours.
It depends on the make and the type of inspection, because the diagnostic equipment itself differs from one car to another. You are told the price before anyone sets off, and it does not move based on what we find.
Japanese, Korean, Chinese, French, German and American, over 115 models in all. If you are not sure about yours, call and ask before you book.
