I had the oil changed. Before that there were no issues. I added the right amount of oil and I have a universal dipstick for Audis that I can check the right level. The MMI cluster shows full, brother drove it ten miles and it showed a message turn engine off, check oil level, but it showed that it was full, then check engine came on. No symptoms. If it was oil pressure message that would have been a big flag. No leaks, just strange. Is this something common out there or are there any TSBs?

Hi,

Believe it or not, there is a technical service bulletin. It is related to the hood sensor. The hood has to be open for at least 30 seconds for the light to reset. There is an issue with the sensor that isn't recognizing that.

If you look at the attachments below, it is the actual TSB. Take a look through it and let me know if it helps.

Take care,

Joe

Strange. So, when I drove home three weeks ago that was about thirty-five miles no messages then. The oil level was about three-fourths on screen. I changed the oil with fresh synthetic, measured on screen and on dipstick using the universal stick, and all was good. So where did I go wrong as far as the 30 seconds? Also, I'm not sure what the last two columns on the right mean as far as value. So, measure the value from the switch on scanner to see if it changes from what to what while opening and closing?

Hi,

According to the TSB, the hood switch doesn't indicate the hood is open. When you open the hood and have the key on, does it indicate the hood is ajar?

Let me know.

Hi,

Okay, that sounds like everything is working correctly, but if the oil isn't low, that still seems to be the prime suspect. Additionally, the manual indicates you have to test the hood switch with a VAG tester. See the directions below.

Check hood contact switch: Use the VAS diagnostic tester to read MVB 26 in the J393 - Comfort System Control Module (address code 46).

If the value does not change when the hood is opened and closed, then replace only the contact switch with part number 8K0 953 236. Follow the applicable work instructions listed in ElsaWeb for replacing the hood contact switch.

Tip:
Do not replace the complete hood latch assembly. Replace only the micro-switch.

This is what I'm finding everywhere I look.

Let me know your thoughts.

Take care,

Joe
