Dealer-Level Equipment
Why Choose Cedar Garage for VW Fault Finding?
Replacing parts in the hope that a warning light goes out is an expensive way to fix a car. Our VW fault finding gets to the root of the problem first, reading every control unit, checking live data and testing the components involved, before we talk you through the next steps. Our technicians are passionate about tracking down faults, including tricky electrical problems that other garages have struggled with, and they work on Volkswagens every day, from the Polo, Golf and T-Roc to the Tiguan, Passat, Touran and Transporter.
You get the same level of VW diagnostic equipment as the main dealer, including software updates and coding, with the personal service of an independent garage. We can collect your Volkswagen from home or work and return it when the work is done, or provide a hire car while it's with us, and we'll never spend more of your money without your approval.

Frequently Asked Questions
VW Fault Finding FAQs
What does VW fault finding involve?
We use VW-specific diagnostic equipment to read any fault codes, then test the parts involved to find the real cause. We'll explain what's wrong and give you a quote before any work goes ahead.
How much does VW fault finding cost?
We start with an initial fault finding check at a fixed price, which we'll confirm when you book. If the fault needs more time to track down, we'll always ask you first.
Can I drive my VW with the EPC or engine warning light on?
If the light stays on and the car drives normally, book it in soon. If the light is flashing or the car is very down on power, stop when it's safe and give us a call.
My VW has gone into limp mode. What should I do?
Limp mode is your VW protecting itself after spotting a fault, so it cuts power. Drive gently and book in for fault finding as soon as you can.
Why does my VW say 'Check oil level' when the oil is fine?
It could be a faulty sensor, or sometimes just a software glitch. Book in and we'll find the cause, and if it's software, we can update it here.
Why is the gear indicator flashing on my VW?
It usually means your automatic gearbox has spotted a fault and gone into a safe mode. Book in for fault finding and we'll tell you exactly what's needed.
Why does my VW's radiator fan keep running?
A fan that keeps running, even when the engine is cold, is usually caused by a faulty sensor or wiring, and it can drain your battery. Book in and we'll find the fault and fix it.
Why is my VW's DPF light on?
The DPF light means the filter in your exhaust needs to clean itself, which usually happens on a longer drive at a steady speed. If the light stays on, or comes on with another warning light, book in for fault finding and we'll take a look.
Other garages can't find the fault on my VW. Can you help?
Often, yes. We enjoy tracking down the trickier faults, and we have the VW equipment to do it properly. Bring along any notes from other garages, as they can help.
Will using an independent garage affect my VW warranty?
No. You can have your VW looked after by an independent garage without affecting its warranty, as long as the right parts and procedures are used. We can update your digital service record too.
Can you look at my hybrid or electric VW?
Yes, for everyday faults such as brakes, suspension and steering. We don't work on high-voltage systems, so we'll let you know if that's where the fault lies.
