🚗 Hybrid Range Rover Sport – Multiple Warning Lights & Brake Concern Resolved 🔧
This hybrid Range Rover Sport arrived with multiple warning lights across the dashboard — and a very concerned owner after the fault developed during a short drive to us.
With reduced braking performance, this isn’t something to ignore… especially in a 2-ton, 400hp vehicle! ⚠️
We began with a full diagnostic check and found numerous communication faults and missing messages across several control units. However, nothing immediately pointed us in a clear direction.
After consulting wiring diagrams and technical service bulletins, we went back to basics 🕵️‍♂️ — looking for a common link between all the faults.
💡 Sometimes, when everything looks complicated… the cause is simple.
Being a hybrid, this vehicle uses both a high-voltage (HV) system and a 12V system. Testing the 12V supply revealed just 8.2V in the auxiliary battery — well below the required level.
Further checks confirmed:
✔️ HV system charging was functioning correctly
✔️ Brake booster module relies directly on the auxiliary battery
Testing the battery showed it had failed.
We installed a known good battery, reset the vehicle, and carried out a road test — everything returned to normal 👍
To complete the repair, we:
🔧 Replaced the auxiliary battery with a new genuine unit (located in the rear load area near the HV battery)
đź’» Performed all required adaptations and programming
✅ Result: A fully restored system and a Range Rover performing exactly as it should — smooth, safe, and refined.
If your vehicle is showing warning lights or unusual behaviour, don’t ignore it — get in touch with the team today.

This Audi A3 came in with several issues the customer stated that the Airbag light was on and the heater controls weren’t working she was unable to raise either the fan speed or the temperature.
Using our dealer diagnostic system “Odis” we found TPI for a software update to the Airbag control module, we verified this software was required and carried out downloading the most updated software version direct from Audi.

The update cured the Airbag fault but highlighted the need to update the software in the engine Power control module (PCM) and Instrument cluster modules due to compatibility with the new software.
After carrying out the software updates to the engine PCM and instrument cluster we set on to the heater fault, using Odis we found no relevant faults and set about checking what switch inputs we could see.
We found all inputs working normally apart from when we operated either the temperature up or fan speed up, using Odis and the manufacturer wiring diagrams we quickly diagnosed the heater control switch pack to be faulty.
We replaced the switch pack and coded them to the vehicle via software variant coding (SVM) through Odis updating Audi to the replacement of these parts, this is done to help assist in stopping stolen parts from being fitted to vehicles.
A full re testing of all the systems was carried out and the vehicle was returned fixed to the customer 👍🏻

Picture a garage in your mind — what do you see?
Maybe a greasy set of overalls, oily hands, and the smell of petrol like in the old films?
Truth is, the modern garage couldn’t be further from that image.

Today’s cars are basically computers on wheels — packed with sensors, software, and systems so advanced they’ve got more computing power than the rockets that went to the moon 🚀.
We’re talking high-pressure hydraulics, electric systems powerful enough to need specialist training, and complex emissions controls that rely on physics and chemistry, working hand in hand.

With self-driving, automatic braking, and ever-evolving tech. Modern vehicles need expert care to stay reliable, safe, and legal.
Think about it — when you’ve got a problem at home, you call an electrician or a plumber.
But in a modern garage, your technician needs to be all of those professions rolled into one (and then some!).

So next time you picture a garage, think less “grease and wrenches” — and more “advanced technology, training, and precision.”
Because behind every modern car is a technician working hard to keep that incredible machine running smoothly.

Here at ATG Auto Tuning we pride ourselves in being able to provide you the level of expertise required to repair and maintain your vehicle to the highest standards.
