Keeping your VW Passat B7 or CC properly maintained is important, but owners often tell us how difficult it is to find reliable information about what needs servicing and when. That's why I've put together this straightforward VW Passat B7 and CC service schedule, covering the maintenance your car needs at each interval.
The information below applies to the following models:
- Volkswagen CC up to 2017
- 2015 Volkswagen Passat B7
- 2014 Volkswagen Passat B7
- 2013 Volkswagen Passat B7
- 2012 Volkswagen Passat B7
- 2011 Volkswagen Passat B7
- 2010 Volkswagen Passat B7
- 2009 Volkswagen Passat B7
Which engine oil should I use in my VW Passat B7 or CC?
Most VW models, including this one, use 5W-30 engine oil. What's more important, though, is the oil specification and the additives it contains. VW has its own oil formulation containing a proprietary silicone additive, exclusive to the manufacturer's genuine oil. This additive helps remove soot and deposits from the sump, unlike conventional oils, which allow soot and deposits to stick to the engine's internal surfaces. In the long run, that can become expensive for you as the owner. Of course, you can use your preferred brand of oil, provided you understand the risks. It must meet the VW 507.00 specification. Just as importantly, remember that for cars driven in Bulgaria, the engine oil and oil filter must be changed every 10,000 km or once a year, whichever comes first, regardless of which oil you choose.
Which filters should I use?
If you've decided to use genuine engine oil, I'd recommend pairing it with genuine filters.
On the other hand, if you've chosen an aftermarket oil and believe aftermarket alternatives are good enough for your car, I don't see much point in insisting on genuine filters.
If your car has a 6-speed DSG gearbox
This gearbox should be serviced every 60,000 km when genuine parts and fluids are used, or every 20,000 km when aftermarket alternatives are used.
If your car has a 7-speed dry-clutch DSG gearbox
Plenty of people and workshops claim this gearbox doesn't need servicing, at least here in Bulgaria. But as you know, there's no such thing as oil that lasts forever when it's lubricating moving mechanical components. The training courses I've attended in Germany emphasise that this oil not only lubricates the mechanical components but also helps cool the mechatronic unit. With that in mind, the replacement interval is 60,000 km for genuine oil (there is no filter) and 20,000 km for aftermarket oil.
If your car has a manual gearbox
Just like the 7-speed DSG, the manual gearbox is often described as having oil that never needs changing. But as you now know, there's no such thing as oil that lasts forever. We'd both have to be dreamers to believe that theory, wouldn't we? The more down-to-earth Germans specify a replacement interval of 120,000 km.
If your car has 4Motion
If the car has drive to the rear wheels, this means it is equipped with Haldex, which uses 2 oils (differential oil and Haldex oil). Both oils are changed every 60,000 km, while the transfer case that transmits drive from the front to the rear axle is serviced at the same time as the gearbox.
Timing belt, auxiliary belt and water pump
Both the timing belt drive and the auxiliary belt drive (also known as the accessory drive) should be replaced every 210,000 km or 5 years, whichever comes first, when genuine parts are used. The water pump and alternator overrunning pulley (Freilauf) are replaced at the same time as the belts. Warranty: 2 years
Important: If your particular vehicle has a belt-driven oil pump, that belt must also be replaced. Failing to do so can result in engine damage.
If you decide to use aftermarket alternatives, the replacement interval is between 20,000–50,000 km and 2–3 years, whichever comes first, depending on their quality. Warranty: not specified (at the workshop's discretion)
Genuine parts do cost around 20% more, but what you're really paying for is peace of mind.
Brake fluid
The manufacturer specifies a brake fluid change every 2 years, regardless of the vehicle's mileage.
Glow plugs
The glow plugs should be checked before every winter. If one is found to be faulty, all four should be replaced. Even if no faults are detected, they must be replaced every 60,000 km because of the risk of the heating element breaking apart and entering the cylinder.
Crankcase ventilation filter
Modern engines have what's known as a crankcase ventilation filter. It has two jobs. The first is to capture oil vapours produced during normal engine operation. The second is to help evaporate condensation that forms while the engine is running. Unfortunately, very few workshops in Bulgaria seem to know when this filter needs replacing, or even that it's a service item in the first place. But yes! It really is a filter, and it needs replacing every 80,000 km. What happens if you don't replace it? The answer is simple. Oil starts accumulating in the intake system, eventually reaches the cylinders and gets burnt. You then notice that your engine is losing oil, take the car to a workshop and hear all the familiar diagnoses from years gone by: turbocharger, valve stem seals and so on. The truth is that this is simply a service item that needs replacing at the correct interval to prevent problems. On this engine, the filter is integrated into the rocker cover. Replacing it also requires removing the injectors, which means their O-rings and seals must be replaced as well. It's nothing particularly complicated. You just need to know it needs doing and make sure it gets done.
Tyre puncture repair kit
Some Passats come with a spare wheel, while others don't. Instead, they have an emergency tyre puncture repair kit. This kit has an expiry date, so you should check it every year to make sure it's still usable. If it's expired, replace it. The last thing you want is to discover it doesn't work when you need it most.
Workshop inspection every 6 months
At Das Auto Service, we encourage our customers to have their cars inspected every 6 months. I'd recommend making this a regular habit, whichever workshop you use. That way, if something is starting to go wrong, you can catch it while it's still a minor issue and get it sorted in good time, rather than letting several problems build up and discovering them all at once, putting unnecessary pressure on your budget.
