    Oil reading a bit strange

    Last week I was driving my CGTS and when I pulled out of a parking lot with a very steep uphill incline, the bottom of the car made a ‘clunk’. I wasn’t happy but I assumed it was just the bellypan. About 5 miles up the road a warning light came on saying that I had reached the minimum oil level. I immediately pulled over and shut down the car. I checked underneath to make certain that I didn’t damage something more serious but saw nothing.

    I added a quart of oil to the car, and started it up, but I still got the same warning. I then let it sit for a bit and checked the oil. It said it was still low (below minimum). I added another quart of oil. Everything seemed ok, but about 10 min later I got another warning that I had overfilled the oil! How can that be? I’m going to do an oil change next weekend anyway, but do you think thAt the oil sensor could have got jarred on some way to make it act strange?

    Re: Oil reading a bit strange

    I doubt that you damaged any part of the oiling system on the car by scraping the bottom at parking lot speeds. I assume you were slowly approaching the steep incline.

    I had a similar experience - I was driving in the hill country of Pennsylvania and parked my car on a very steep incline for a few minutes to take some pictures. When I got back on the road I got a low oil message ( the night before when I parked the car I checked the oil and it was full ) I kind of panicked but thought my car was full of oil a few hours ago so I didn’t add oil. I drove the car to a level spot and opened the trunk ( opening the trunk resets the oil sensor ) got back in and drove a few miles and rechecked the oil level by parking on level ground and waiting 1 minute prior to rechecking the oil and all was good. I believe all the oil ran to one side of the motor and the sensor didn’t get an accurate read after being parked on such a steep incline.

    Bottom line I believe you have over filled your car. The difference between the min and max levels on the oil display are 1.8 quarts. I’d definitely drain some oil off or better yet do the oil change you mentioned and start fresh.

    Do you know what level your oil was at before you started out that day ?

    I personally check my oil after each ride and if I do need to add oil I add approximately 400 ML at a time and then recheck it using the proper procedure - oil up to temp, park on level ground, wait 1 minute and the take my reading.

    Running a car with over filled can cause fouling of the catalytic converters amongst other issues.

    Look at pages 88 and 203 of the owners manual.

    Good Luck

    Re: Oil reading a bit strange

    Thanks for the note! I’m definitely to do the oil change (I’m at 10,000 miles) before driving it again. I didn’t check the oil level before I drove it that day, but your experience does sound interesting as well. I did not know that owning the rear hatch reset the sensor. Thanks!!

    You may want to check the sensor on the bottom of the pan and the wires from it for damage. There was someone last year who damaged the wires during an oil change and got crazy readings. It should all be visible if you are under the car doing an oil change.

    Re: Oil reading a bit strange

    I agree with Jim137a - parking on a slope can confuse the oil sensor. Same thing happened on my 981 BS a year ago - I parked in a steeply upward sloping parking space next to a store for a few minutes. When I came out I got a low oil warning on the display. I knew the level was good and I was only a mile from home so I ignored it, but it was a bit disconcerting! The next day the reading was fine again, and no oil was added. So beware of those slopes!

    Don't know how many times I've said to myself... "Why the heck didn't Porsche put a dipstick on this thing?"

    Thanks for all the feedback. I’ll take some pics when I have her on the lift this weekend.

    Re: Oil reading a bit strange

    Yep, me too! We just picked up a new Audi Q5 and same thing - no dip stick... there is a tube for one but it is sealed off and there is no stick. And to check the oil you have to go 3 or 4 levels deep on the infotainment system to get there... Great way to get people to never check their oil! :-(
