I recently took my RS3 to WRSC Performance to have an eventuri turbo elbow and intake installed, and I couldn’t be happier with the experience. Shunt and his team were professional, honest, and upfront from the start. They explained exactly what would be done, kept me informed throughout the process, and completed the work within the timeframe they promised.

The quality of the workmanship is outstanding, and it’s clear they really know these cars inside and out. If you’re looking for true RS3 specialists who take pride in their work, WRSC Performance is the place to go. Thanks again to Shunt and the team, I highly recommend them!

Outstanding service. Very quick, professional and just all round above and beyond.

Found from the minute I walked in I was welcomed and given the time of day. Got two cards checked for a pinkslip on short notice and they processed both extremely quickly during my lunch breaks. Wish I could rate higher!

Character growth is doing the safety check early at West Ryde Service Centre instead of treating it like a surprise boss battle 🤣 Thanks guys.

As someone who works in the automotive industry myself and pays close attention to workmanship, service quality, and attention to detail, I can honestly say the team at West Ryde Service Centre (WRSC) have been exceptional.

They’ve looked after both my G80 M3 and F95 X5M for servicing and tuning, and every experience has been professional from start to finish. Their communication, transparency, and genuine care for the cars really stand out.

What I appreciate most is the attention to detail — not just mechanically, but in the overall customer experience as well. It’s rare to find a workshop that combines technical knowledge with such high standards of service and consistency.

You can tell these guys are passionate about what they do, and they treat every vehicle with respect. It gives real peace of mind knowing the cars are in capable hands. Highly recommend WRSC to anyone looking for a trustworthy workshop that genuinely cares about quality.

step by step

Our Battery Service Process.

Book or Drop In

We'll fit you in fast — book online or just call ahead. Same-day service is usually available for battery replacement.

Free Battery Test

A full load test, CCA measurement and alternator output check tells us whether you actually need a new battery.

Transparent Quote

If replacement is needed, we quote the correct battery for your vehicle before any work goes ahead — no surprises.

Quality Battery Fitted

We fit a battery matched to your vehicle's specification — standard, EFB or AGM — and dispose of the old one responsibly.

BMS Reset & Coding

For European and stop-start vehicles, we register the new battery with the ECU so the charging system works as intended.

System Re-Tested

Before you drive away we re-test the charging system to confirm everything is working — backed by our lifetime workmanship guarantee.

The Right Battery for Every Make & Model

From daily drivers to European luxury vehicles, we fit the battery your vehicle was designed for. Under Australian Consumer Law, you’re never required to use a dealership to keep your warranty valid — and a correctly specified, professionally fitted battery protects it.

// EUROPEAN BATTERY SPECIALISTS

Driving an Audi, BMW, Mercedes or VW?
Your New Battery Needs Coding.

European cars with battery management systems must have a new battery registered with the ECU — otherwise the charging system never adapts, and your new battery can fail within months. Our European Car Servicing page covers the specialist diagnostics and expertise your vehicle needs.

Car Battery FAQ

Slow cranking, dim dash lights at start-up, or needing a jump-start are the classic warning signs. If your battery is more than three years old, bring it in — our free ten-minute test measures its actual cold-cranking amps against what your vehicle needs, so you know before it leaves you stranded.
Typically 3–5 years, but Sydney’s hot summers shorten battery life — heat accelerates internal corrosion. Stop-start systems and short trips also work batteries harder. Most batteries we replace in Sydney are between three and four years old.
It depends on your vehicle: a standard battery fitted typically starts from around $200, while AGM batteries for stop-start vehicles cost more because of the technology inside. You’ll always get an itemised quote before we fit anything — and the battery test itself is free.
AGM (Absorbent Glass Mat) batteries handle the constant charge cycles of stop-start systems. If your car switches off the engine at traffic lights, it needs AGM or EFB technology — fitting a standard battery causes charging faults and premature failure. We match the correct type to your vehicle every time.
Audi, BMW, Mercedes-Benz and Volkswagen vehicles use a battery management system that must be told a new battery is fitted — its type and capacity have to be registered so the alternator charges it correctly. Skip the coding and the system overcharges or undercharges the new battery. We perform BMS resets with factory-level diagnostics.
No. Under Australian Consumer Law, you’re never required to use a dealership for servicing or parts to keep your warranty valid — as long as the work is done properly with a correctly specified battery, which is exactly what we do.
Yes — drop in or book online. The test takes about ten minutes and covers the battery’s cold-cranking amps and the alternator’s charging output. Same-day replacement is usually available if you need a new battery fitted.
We send every old battery to accredited recycling — lead-acid batteries are almost entirely recyclable. There’s no disposal charge when we fit your new battery.
