Vehicle coding

Vehicle Coding Reading

Some of you, especially if you think of yourselves as petrol heads, will be familiar with vehicle coding. Most people, though, won’t know what it involves, or even that car coding is possible. It’s a relatively new service, so it isn’t a common phrase yet in car parlance. At Mobile Mechanic Reading we try to keep abreast of most car enhancement options, alongside services such as engine remapping, so that we can offer car coding in Reading when our customers want it.

Most people assume that the features on their car are fairly fixed by the model they have. Programmes such as Pimp My Ride have shown that a vehicle can have all sorts of alterations and additions, but most of those examples aren’t exactly subtle. Bigger wheels and tyres, or a lighting system inside and out, would be classed as modifications.

Vehicle coding is much more subtle. It focuses mainly on your car’s electronics, and on how they interact with the parts and features your car already has. Some enhancements may need a modification as well, and we’ll tell you if yours does.

Factory settings

Car Coding

Car coding is mainly about changing the original factory settings for your particular model. Changing the software can alter how the car reacts, and how it works with other components and displays.

Some of your car’s settings come from local regulations, but many come down to the model you have. Most models come in versions with a different name, letter or number for each combination of engine and specification: L, GL, Ghia and GT on older cars, A4, S4 and RS4 at Audi, or SE up to Ultimate Nav on the Vauxhall Crossland. From the outside you’d be hard pressed to spot the difference, but inside, the basic SE has a number of blank buttons where the Ultimate Nav has none, because you pay for the extra features.

A simple way to think of car coding is moving your SE a step closer to the Ultimate Nav. Coding can switch on or change features your car’s electronics already support, while features that need extra hardware mean parts being fitted too.

Coding options

Car Coding Options

Now you know what vehicle coding is about, what changes can you make? You may already have ideas from what a friend’s or partner’s car does, or there may be something about your own car that irritates you and that you wish could be changed. Here are some examples.

  • Start/stop

    Your automatic start/stop always starts as on. We can change the default so it always starts as off.

  • Alerts and warnings

    Change the sound or duration of touchscreen and warning alerts, or adjust the seatbelt warning if you carry heavy items on the back seat and the car thinks you have a passenger.

  • Lights

    Change factory light settings, such as lights coming on in clear daylight, which wears them out sooner, or the lights that come on when you lock or unlock the car.

  • Mirrors and reversing

    Fold the wing mirrors in when the ignition is off, lower them when you select reverse to help you see behind, or add a warning sound if the car rolls backwards.

  • Locking, windows and handbrake

    Lock the doors automatically at a set speed, close all the windows with a double press or long hold of the key, or remove the electronic handbrake’s auto-hold, which many drivers struggle with.

  • Digital displays

    Show a speed closer to your actual speed, and change fuel consumption settings, when gear changes kick in for each drive mode, how incoming calls are shown and what appears on the dashboard screen and the driver’s screen.

Is car coding the same as modifying a car?
