When to do your first oil change?

A dirty filter constrains the free flow anyway. So, even if manual says 10,000 miles, I had my first oil change at 5,000. I used a kit from IDparts.com containing 5 liters of oil (I chose Pentosin 5W30 VW 507.00 spec, friends in Europe like it), an original replacement filter cartridge with 3 o-rings, and a standard plug for about $70 with shipping. Look for a kit for 2012 Passat (B7 chassis, CKRA engine code). You will need following tools: T25 Torx screwdriver, T47 Torx driver tip to remove a plastic cover under the engine and transmission, 32 mm shallow 1/2 inch drive socket to remove the oil filter housing cover, 1/2 x about 4" long drive extension, 1/2 inch drive torque wrench, 3/4 inch socket wrench (for the oil plug). Once you remove 9 T25 screws from the sides and the front and 3 T47 bolts in the rear, gently insert flat screwdriver and lift the edge of the apron on the right just enough to clear a snap tooth from a slot and slide the cover skirt back and out of the way. The oil drain plug is clearly visible. Before you do that remove and replace the filter cartridge. To do that gently lift a plastic engine cover starting with unsnaping one corner first and gently following around (4 snap posts). Put it to the side. The filter housing is located to the right and front of the engine. You will notice a large hex on the black filter housing cover. Use 32 mm socket, extension and 1/2 inch driver to losen the cover. It will resist slightly (there is a large o-ring on it). The cap/stem and filter will be freed up as one assembly. You may need to move a black cable bundle slightly and carefuly out of the way, while wiggling the cover and filter upand out. It is rather tight between the engine head and a metal pipe wrapped with a greyish fiberglass shield, so don't get frustrated. Pull filter cartridge off of the cap. It will unsnap. Observe which way the filter was installed. The holes on both sides of the cartridge are different so it goes on only one way. Replace all o-rings. There is one large between the flange and the top of the thread (make sure you put new one into the gland correctly) and two small ones that go onto the stem tip (two diffrent sizes). Do not use sharp instruments to pull dig o-rings out of their glands. Use small wooden tonque depressor or a plastic equivalent. After putting new orings on snap the new filter cartridge onto the stem (remember to use proper end towards the cover). Do not put the filter into the housing yet. Loosen the 3/4 inch oli plug and drain old oil. Replace new oil pan plug and crushable gasket (comes with the new plug) using torque wrench. Torque to 18-20 ftlb (that is about what I measured on an installed plug). Do not overtorque, The pan is aluminum and the plug is steel. It is easy to strip the threads. Wet all o-rings with fresh engine oil with a finger and negotiate the whole assembly gently into the housing. Screw start the cover in by hand to make sure that the thread is properly engaged. It is easy to cross thread it. At some point you will fill slight resistance that means the o-rings are engaging. Remember, just some resistance. If you forcing it too much you may be cross threading. The housing and the cover are made of plastic. Use 32mm socket, extension and the 1/2 torque wrench driver and torque the cover to 16-18 ftlb (again that is what I measured). Do not overtorque. Remove engine oil filler plug and using a clean funnel put in all 5 liters of oil in. The capacity for this engine is 5.02 liter (per manual). Replace filler plug. Snap the engine cover back. Replace the undercarriage apron cover sliding forward and installing all torx screws and bolts. You are done. Before you replace both cover and undercarriage apron you may want to start the car, run the engine for a while and check for leaks. Ther shouldn't be any, if you did it right. Hope it helped.

Good luck

I need to quickly reply tomy own post. I suggested a wrong torx tool size for 3 rear bolt it is not T47. It is T45.Please get a right size. Sorry for a mistake. It was a busy post anyway.
