Volkswagen Caddy 1.6 TDI CAYD (2008): Engine Oil and Oil Filter Change

On the CAYD (1.6 TDI Common Rail), the oil is changed together with the filter element, which sits in a plastic housing on top of the engine. The manufacturer's stated interval is up to 15,000-30,000 km or 1-2 years. For short trips and heavy stop-and-go traffic, it makes sense to change it every 10,000-15,000 km or once a year.

Difficulty: Easy Time: 40-60 minutes Steps: 12 Tools: Wrench or socket for the drain plug (size and profile depend on the oil pan, so check against the plug on your vehicle), socket or wrench for the oil filter housing cap (usually 36 mm on this engine, check against the cap), torque wrench, drain pan of 6 L (6.3 qt) or larger, funnel, shop rags, and a screwdriver or Torx driver for the skid plate if needed

Part

  • 🔩 Oil filter element for the 1.6 TDI Common Rail (paper filter element inside the housing cap, OE VAG, aftermarket Mann, Mahle, Bosch), O-rings for the filter cap (usually supplied with the element), new drain plug washer. Engine oil: about 4 L (4.2 qt), with a refill capacity including the filter of roughly 3.8-4.3 L (4.0-4.5 qt). Oil type: 5W-30 synthetic meeting the VW specification. Versions with a diesel particulate filter (DPF) require the low-ash VW 507 00 specification. Versions without a DPF can also use VW 504 00 or 505 01. Confirm the exact specification on the sticker in the service booklet or on the oil filler cap

Step by step

12 steps
  1. Warm the engine up to operating temperature (5-10 minutes), then shut it off. Hot oil drains better, but be careful of burns. Let the engine sit for 5-10 minutes so the oil can drain down into the pan.
  2. Park the car on level ground, over a pit, or on a lift. If fitted, remove the plastic skid plate if needed.
  3. Open the hood and remove the decorative engine cover. Remove the oil filler cap so the oil drains faster.
  4. Place the drain pan under the oil pan and remove the drain plug. Let the oil drain completely, which takes 10-15 minutes.
  5. While the oil drains, locate the oil filter housing on top of the engine. Place rags around the housing so you don't spill oil on the belt and accessories. Unscrew the filter cap counterclockwise. The old filter element comes out together with the cap.
  6. Remove the old element from the cap and replace the O-rings with new ones. Lubricate them with clean engine oil. Do not reuse the old O-rings, or the housing will leak.
  7. Install the new element in the cap, screw the cap back in, and tighten it with a torque wrench to about 25 N·m (18 lb-ft). Check the exact value against the marking on the cap and the service specification. Do not overtighten: the plastic cap cracks easily.
  8. Clean the drain hole and the plug, fit a new washer, and tighten the plug to about 30 N·m (22 lb-ft). The range is 25-40 N·m (18-30 lb-ft), and the exact value depends on the plug type and oil pan.
  9. Pour about 3.5 L (3.7 qt) of oil into the filler neck, wait a couple of minutes, and check the level with the dipstick. Add oil in small amounts until the level is between MIN and MAX, closer to the upper mark. Do not overfill.
  10. Close the filler neck and start the engine for 30-60 seconds. The oil pressure light should go out immediately or within 1-2 seconds. If the light stays on, shut off the engine immediately and find the cause.
  11. Inspect the drain plug and filter cap for leaks. Shut off the engine, wait 5-10 minutes, then recheck the oil level and top up if necessary.
  12. Reset the service interval indicator through the instrument cluster (the procedure depends on the cluster version). Take the used oil and old filter to a collection point for used oil.

Common mistakes and warnings

  • Do not use oil without a VW approval. On a Common Rail engine with a DPF, unsuitable oil quickly clogs the DPF and shortens the life of the injectors and turbocharger. Do not overtighten the plastic filter cap, and do not reuse the old O-rings. Hot oil and the exhaust system can cause burns, so wear gloves.
