VW, Audi, Skoda and SEAT servicing: fixed or flexible?

Volkswagen, Audi, Skoda and SEAT are one group, and for servicing purposes they work the same way. That's genuinely useful to know, because it means the same question decides what your car needs whichever badge is on the bonnet: is it on the fixed regime or the flexible one? Plenty of owners have no idea, and it changes both how often the car is due and what it costs. Here's how to tell, which one actually suits how you drive, and the things worth knowing before you book.
Fixed or flexible: the question that decides everything
Every car in the group is set to one of two servicing regimes, and it's set in the car's own software rather than written on it anywhere obvious.
On the fixed regime, servicing comes round on a schedule: Volkswagen puts it at typically every 12 months or 10,000 miles, whichever comes first. Predictable, and it suits most people.
On the flexible regime, sometimes called long-life, the car works it out. It watches how it's actually being driven and puts the service light on when it decides the oil has had enough, which can stretch a good deal further between visits than the fixed schedule.
Neither is better in the abstract. What matters is whether the one your car is set to matches how you actually use it.
Which one suits how you drive
Flexible is built around long, steady runs. If most of your miles are motorway or A road, the engine gets properly hot, the oil stays in good condition, and stretching the interval is exactly what the system is for.
Fixed suits short journeys. If your driving is mostly a few miles across town, school runs and cold starts, the engine barely warms through and the oil degrades faster than the mileage suggests. On a flexible car that pattern can leave tired oil in the engine for longer than is good for it.
So if you bought the car second hand and you do short trips, it's worth finding out which regime it's on. Switching a car from flexible to fixed is a change to how the car is set up, and it's a fair thing to ask about.
How to find out which one your car is on
The honest answer is that you usually cannot tell by looking. A main dealer can tell you what the car is set to from the registration, and can print its service history.
One catch worth knowing: they can only see work done inside the manufacturer's own network. If the car has been serviced independently, as most cars are once they are a few years old, that work will not show up in their records even though it happened.
There is no paper service book any more
This one catches people out at exactly the wrong moment, usually when they come to sell. Volkswagen stopped issuing physical service books in May 2017. Everything since is a digital record.
So an empty book, or no book at all, is not evidence a car has been neglected. Equally, if you are buying, a full paper book on a recent car is not the reassurance it once was. Ask for the invoices, and ask the retailer to print the digital history.
It cuts the other way too. When we service your car we give you the invoice detailing what was done and what went in, and that paperwork is what proves the car was looked after. Keep it: on a car of this age it is worth real money at resale.
The oil is not a place to save money
The group approves specific oils rather than accepting anything of the right grade, and a flexible-regime car is fussier still, because the oil has to survive a longer interval.
The part that really matters is particulate filters, which means every current diesel and a lot of recent petrols. Those need a low ash oil, because ordinary oil leaves deposits that block the filter over time. Putting a cheaper oil in a long-life car is the worst of both worlds: it is being asked to do more, and it is less able to.
We check the requirement against your car rather than assuming. If you have bought oil yourself and it carries the right approval, that's fine and we'll use it.
Rear brakes, AdBlue, and one thing we don't do
Two practical points and one limit worth knowing before you book anything, with anyone.
Most modern cars in the group have an electronic parking brake, so the rear caliper pistons are driven by motors and can't be wound back by hand to fit new pads. The car has to be put into a service mode and reset afterwards. It's a question of equipment rather than difficulty, and it's why some places won't do rear brakes away from a workshop.
The diesels use AdBlue, and the car gives you a long countdown before it runs out. Take it seriously: once it reaches zero the car won't restart.
And the limit: we don't take on DSG or automatic gearbox work, on any make. This group fits a lot of DSGs, so it's worth saying plainly rather than having you find out on the day. If that's what your car needs, we'll tell you straight and point you the right way.
