Digital Oil level Problems

[derhase18t]

I have a question about the digital oil level gauge. When I turn the key, it counts down from 5 seconds, but rather than showing a full level (which the dipstick shows, and driving around without seizing the engine confirms) it flashes empty. I called the dealership and they quoted around $85 for the oil level sensor. However, when I talked to service, they said that they have only seen that 5 times in the past 10 years, and each time it was because someone hooked up jumper cables to the battery backwards, and damaged the circuit board behind the gauge cluster. The only way to fix it, of course, is to replace the entire gauge cluster, which new would be $1800.

Has anyone had this problem before? I am really hoping that it is just the sensor, or possibly a bad connection, and not the cluster. Other than the frustration of having a non functional digital dipstick (I have never had one before, so I am really not missing out) is there any problems with just leaving it as is, or should I anticipate the rest of the cluster to go out eventually as well?

I doubt anything else will be affected if you do nothing, and if nothing else goes out, you don't have to come out of pocket to fix this issue.

Your conventional dipstick works nicely and my Porsche tech doesn't really put much stock in the digital one anyway because it reads so differently depending on when you measure your oil level... the motor should be off for 1/2 hour and on a level surface to get an accurate read with the digital oil level gauge.

BTW, you can buy a cluster off eBay for $250 from time to time. Keep an eye out for the one you need based on your part number. Each model year requires it's own version, so they're typically not swappable between MY's. Some are new and unprogrammed and it's just $100 at the dealer to do it. Others require reprogramming, which can be done through Palo Alto Speedo in California.

What is the history of the car and this issue?

Randall, thanks for the info. I had seen the clusters on ebay but didn’t know what was involved in the swap. Is this something that can be easily done, or does it require special tooling? I have plenty of experience with disassembling domestics, just a little nervous when it comes to taking the dash of my Boxster apart.

In terms of the cars history, its a 2 owner, low miles (39k) car. I wasn’t too concerned about the problem, just something I would like to get fixed for the sake of getting it fixed.

It's easy. Two screws and three or four plugs. Swapping it out takes about 15 minutes tops.

Be sure to reply to ToolPants request...his level of expertise in these matters far surpasses my own. Heck, I learned most of what I know from him!

Sent ya a PM... I've got an extra cluster available
