Composite pan with built-in filter for the Audi 0D5 (ZF 8HP65A) 8-speed in the Q5, Q7, A4 and S4. Replaces OE 0D5398009 and ZF 1103298006.
Owners of a 2016-2017 Audi A4, A4 Avant, S4 or Q7 usually find this part one of two ways: a drip of green fluid from the corner of the transmission pan at an oil change, or a high-mileage car with sluggish, harsh shifts that has never had its eight-speed serviced. Both lead to the same part. The Audi 0D5 transmission is ZF's longitudinal 8HP65A, and its filter lives inside the pan. This composite pan replaces Audi 0D5398009 and ZF 1103298006 and brings a new filter with it.
The 8HP65A sits behind the 2.0T and 3.0T engines in these cars, with the mechatronic unit mounted directly above the pan. The pump pulls fluid up through the filter molded into this PA66 pan and feeds it to the mechatronic, which controls every clutch and the converter clutch. The pan is not just a cover: it is the reservoir, the filter housing and the main sealing surface on the bottom of the case. When the plastic cracks, the bolt bosses strip, or the filter loads up with friction material, the whole part is replaced as one unit. ZF documents this directly: plastic 8HP pans carry an integrated filter, while aluminum and steel pans use a separate one.
Keep expectations honest. The 8HP family is known for mechatronic sleeve leaks that drop pressure and for harsh shifts tied to adaptations. A new pan and filter will cure a pan leak and a restricted filter. It will not cure a worn clutch pack, a faulty mechatronic or a converter fault.
Clean the area and confirm the leak is actually the pan seal and not the cooler line connections or the axle and output seals, which can wet the same area. Then check the level properly: the 8HP has no dipstick, so the level is set at the fill plug with the engine idling and the fluid between 30 and 50 C on a scan tool. Our ZF8HP filter and pan service guide covers identifying which pan you have, and the ZF8HP common problems guide helps rule out the mechatronic and clutch faults first.
The US fitment listed for this pan is the 2016-2017 Audi A4, A4 Avant and S4, and the 2016-2017 Q7. The same 0D5 pan is used in later Q5, A5 and S5 and other 8HP65A applications, but Audi used several eight-speed pans over the years, and other Audi eight-speed applications carry different transmission codes and pans. Read the part number on your existing pan and confirm it matches 0D5398009 before ordering, or send us the year and VIN and we will check it. All of our ZF eight-speed parts are on the ZF 8HP transmission parts page.
For enough fresh fluid to finish the job, add the ZF LifeguardFluid 8 7-liter service fill. If you want new drain and fill hardware as well, the ZF 8HP pan filter kit with gasket, drain plug and screws is the alternative to compare.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. The filter is molded into the composite pan, so the pan and filter are replaced together as one part. There is nothing separate to install.
The listed US fitment is the 2016-2017 A4, A4 Avant, S4 and Q7. The 0D5 pan is used on later Q5 and A5 models too, but Audi used several pans, so match 0D5398009 on your old pan or send us your VIN.
ZF LifeguardFluid 8 or the Audi/VW approved oil G 060 162 (A1, A2 or A6), which ZF lists against the same approved fluid group as the 8HP65A. Do not use additives.
ZF lists 10 N-m for plastic 8HP pan bolts, tightened crosswise from the center out after every bolt is started by hand.
Usually a hardened pan seal, gasket residue left during a previous service, a cracked pan or a stripped bolt boss. Confirm it is the pan and not the cooler lines or an output seal before replacing it.
Only if old fluid and a restricted filter are the cause. Harshness that remains after a correct fill points to adaptations, the mechatronic or clutch wear.
