Audi Aircon Regas Walsall

If your Audi is blowing lukewarm air on a warm day, it is easy to assume a quick top up will sort it. But as we show in the video below from a recent job at Platinum Vehicle Services, a professional aircon regas is about more than just adding refrigerant. It is about making sure the system is clean, leak free, and set up to last.

What We Actually Do During an Aircon Regas

We do not just pump in new gas and send you on your way. Our equipment runs a precise three stage process. First we pull the system into a vacuum, removing any old refrigerant and moisture. Moisture is the enemy of your AC compressor and if it is left inside the system it causes internal corrosion over time. Once the vacuum is holding, we confirm there are no significant leaks before we proceed. Then we inject the correct refrigerant to the exact weight specified for your vehicle. For newer Audis that is R1234yf, the current industry standard for post 2017 cars. Getting the weight right matters. Too little and the system underperforms. Too much and the compressor is put under unnecessary strain.

UV Dye and Why We Add It to Every Regas

During the refill we add a UV leak detection dye to the system. Aircon pipework is often buried behind the engine or routed through the dashboard, which makes tracing a slow leak genuinely difficult without the right tools. The dye solves that problem before it becomes one. If your AC ever develops a leak in the future, we pass a UV light over the system and the dye glows at the source immediately. No guesswork, no stripping the car down to find a pinhole. It saves diagnostic time and it saves you money.

How Often Should You Service Your Aircon

Most manufacturers recommend an aircon service every two years. Refrigerant naturally escapes through rubber seals over time, and as the charge drops the system has to work harder to maintain the same cabin temperature. That extra load goes on your compressor and on your engine, which means higher fuel consumption and more wear on components that are not cheap to replace. If your AC has not been looked at in a couple of years, or if it is noticeably less effective than it used to be, bring it in. We will run through the full process, add the UV dye, and make sure the system is working as it should before the weather demands it.

DPF Regeneration Walsall. What That Smoke From Your Exhaust Actually Means

If you have ever seen thick white or grey smoke pouring from the back of a diesel car and assumed the worst, you are not alone. Most drivers do. But on an Audi Q5 we recently worked on at Platinum Vehicle Services, that smoke was not a sign of engine failure. It was a sign of a diesel particulate filter being saved from a very expensive replacement.

What Is a DPF and Why Does It Block Up?

The diesel particulate filter sits in your exhaust system and traps the soot produced during combustion. Think of it as the lungs of your exhaust. On cars used mainly for short journeys or stop-start driving, soot builds up faster than the car can burn it off on its own. When the filter gets too full, you will notice the signs. Reduced power, poor fuel economy, a warning light on the dash, or the car dropping into limp mode. Left too long, a blocked DPF can mean a full replacement costing well over £1,000.

What We Actually Do During a Forced Regeneration

When a diesel cannot clean its own filter through normal driving, a technician has to step in. We connect a professional diagnostic tablet to the vehicle and initiate a stationary regeneration cycle through the software. The engine runs at elevated RPMs while stationary, exhaust temperatures climb to over 600 degrees Celsius, and the accumulated soot is burned off. The white smoke you see in the video below is the byproduct of that process. It looks alarming. It is not. It is a DPF being cleaned rather than replaced.

Regeneration vs Replacement

A forced regeneration at Platinum Vehicle Services costs a fraction of a full DPF replacement. A new DPF for an Audi Q5 can run to £1,000 or more including labour. In many cases a forced regen is all that is needed to restore the filter and get the car driving normally again. The key is catching it early. If you have noticed a DPF warning light, limp mode, or your diesel has been used mainly for short trips, bring it in. We will assess the filter, carry out the regeneration, and give you a straight answer on whether cleaning is enough or whether replacement is the more sensible long-term option.
