To which manual are you referring? I think that you may be referring to the PDK for the Carrera. The unit in the Panamera is unique to the model, in that it does not have separate clutch and gearbox fluid. It takes 9 - 9.5 quarts of FFL-3, as per the Porsche Dealer's technical information. There is only one drain plug and one fill plug on the entire unit. The front differential uses about a half a quart of the 75w90 OE Porsche Oil, or Shell equivalent.

I have a 2012 Porsche Panamera 4 with 67k miles. Bought it at 34k miles as a certified pre owned Beautiful car, perfect condition, brilliant road trip machine. We use it for trips around the intermountain west almost exclusively. However, the PDK unit began acting up on a recent trip: Specifically, there are three symptoms exhibited in during the following conditions: 5th or 7th gear engaged, light to moderate acceleration/throttle (shift mode manual/auto of sport/regular mode do not make a difference) 1) A rattling noise from the transmission, 2) a very slight fore-aft jerking motion, 3) tachometer needle wavers quickly up to 100rpm. These symptoms manifested roughly 500 miles after a PDK oil and filter change. I used an OE Porsche pan/filter assembly/ OE pan bolts, and Pentosin FFL-3. Followed Porsche's temperature-based fill and level check procedures. I used a Snap-On Triton D8 scan tool used to monitor fluid temperature. I changed the PDK fluid with Pentosin FFL-3 at 35k miles as well, and had zero issues in the interceding 32K miles. The local dealer reported that the fluid was 9/10ths of a quart low. Hard to believe as I double-checked the level after a drive cycle. They declined to perform an engine torque adaptation or driving calibration of the PDK. They instead proposed transmission replacement to the tune of $24,500. They said they don't repair PDK transmissions. This from a large dealer with lots of sales and service volume. The shop foreman suggests that the 6th gear syncro is failing, but no parts are available. Since the PDK has two forward gears engaged at all times for quick shifting- with only one engaged for the power path - 5th a and 7th gear rattles makes sense, to a point. When pushed, the transmission will shift through forward gears flawlessly. I am at a loss, for I am hesitant to drop $25k on a car that is worth perhaps $32-$36k. Any Panamera owners out there that have experienced similar issues?
