All Models

Engine

• Change Oil Filter (5000-6000 miles)
• Change Oil - VW Silver Synta (10W/40) is recommended and Silkolene Pro S 10W/50 Fully Synthetic is also reported to be excellent
• Change Spark Plugs (see model)
• Check All Fluid Levels (Coolant, Power steering Fluid, Brake and Clutch Fluid)
• Check Belts / Gaskets - Cam belt + Tensioners bearing etc
• Check Wear on Rotor arm and Distriutor Cap (excluding Coil pack Vr's)(replace if needed)
• Clean or Replace Air Filter Element (re oil if aftermarket K&N type are used. Only Clean when needed as per recharge instructions)
• Check Fuel Lines on the underside of the Car
• Replace Fuel Filter every 2 years
• Check HT and LT leads for signs of damage.
• Check Exhaust for Leaks. Check Exhaust probes for signs of damage to them or wiring.
• Check Earth Straps on Bonnet, throttle body, and gearbox.
• Check Vacum pipe to ECU box.
• Check wiper linkages for excess play. All wiper parts are dirt cheap.
• Plug in VAG-COM diagnostics if available

Suspension

• Check CV Joints
• Check wheel bearings
• Check Shocks for leaks
• Check Rear Break compensator valve is opertating correctly

Brakes

• Check front and rear pad wear, replace pads where needed.
• Check Brake Discs for signs of damage and wear (check thickness is within tolerances)
• Check Handbrake Operation
• Check Brake Lines so signs of damage or corrosion.

Gear Box Oil

• Castrol TAF-X (formulated for VW gearboxes) or Redline MT-90

Coolant

• G12+ (plus) Only Coolant to use and only coolant VW recommend now, can be mixed with G11 and G12

Other bits

• Grease Seat Runner, Door Handles, Door Latch
• Check All Lights, (replace bulbs where needed)
• Check Battery
• Check Opertation of Spoiler and lubricate with a dry teflon based grease.(do not oil as it gets into the boot)
• Check Window operation and grease guides if needed. (do not over grease).
• Sunroof operation and condition of seal, and drain holes
• Underseal (under car)

G60 Only

• Change Spark Plugs Spark Plugs x 4 BOSCH W6DP0
• Service G-ladar unit (40,000-60,000 miles depending on pully size)
• Check for Boost Leaks and signs of charger oil leaks inside the main boost output pipe that goes to the intercooler. Excess oil could mean rebuild is required.
• Check Intercooler for signs of Damage

VR6 Only

• Check plugs 1 and 6 periodically for oil fouling
• Clean the Idle valve and throttle body quarterly
• Keep an eye on the oil level as they drink a bit
• Periodically slacken the serpentine belt and spin the tensioner pulley, checking for stiffness
• Periodically check serpentine belt for cracking and splits
• Listen to the gearbox side of the head occasionally for chain slap noises
• Invest in VAG-COM and scan the engine every nown again for sensor malfunctions
• Periodically check the lower half of the front engine mount for splitting. The engine will hit the bonnet if it lets go.
• Check for coolant leaks around the thermostat housing and auxillary pump

To save confusion on the VR6 oil filter, as there are 3 different types, the attached pic might help. I believe all ABV engines have a non-return valve type filter. I've bought the wrong one twice now as I keep forgetting, so this will be a permanent reminder!

16V Only

8V Only (non-G60)
