Does anyone know what the min and max oil levels should be as reported using Vag-Com/VCDS for a B8 8K Audi A4 (2009 Model), 3.2 v6 automatic?

I just had my oil changed (since it was time and the oil low indicator was on), and the garage said they put 7q in but the low oil indicator is still on.

Ive grabbed the info via VCDS (shown below) so if anyone can post similar logs it would be helpful.

Im going to add some more incrementally and watch how this changes, but knowing where it should be (rather than just "add another 1q") would be nice to know. Also, having a darned dipstick would be nice...

Added 0.5q, low oil still on:

As far as I can tell, nothing there has increased so Im guessing Im not looking at the right fields in the engine controller.

Best bet is to get the $27 dipstick (for 2.0T engine). If the dipstick level is correct, you may have a faulty sensor. Don't add more oil until you check it with the dipstick.

The specified oil volume for the 3.2FSI (I had before) is 6.2 liter (including filter change).
I'm not sure about your measuring unit (is it 1/4 US gallon?) but I think 7 of those is already too much.
My car came (new) with a dip stick, but I don't know what part nr it was.
I don't believe it is the same as 2.0T.

They are different but unless the OP has a 2009 A4 with a 3.2 (the only year that engine was available in the A4 B8), the dipstick I listed is for all B8 A4s which otherwise only offered the 2.0T engine.

I read in his post "B8 8K Audi A4 (2009 Model), 3.2 v6"

I would first check engine hood switch. Make sure the hood open display is on instrument cluster when you open the hood. If it does not detect the hood open/close, it will not update engine oil level.

StanAccy

Thanks for all the suggestions. My engine is 3.2l US/North American spec, measurement unit for oil capacity isus quarts. I checked the hood latch - I don't see any change on the dash with the hood open so I'll see if I can extract the microswitch inside the latch mech and check it.

I read somewhere that I can read the hood latch state using [46]-MB26. Does anyone know if this is correct for the B8 A4s?

snagitseven

Argh.. you're absolutely correct. I missed that in the post.

Quick update. After hooking up VCDS this morning, and checking both Controller 46, MB26 (which is the hood latch - I confirmed that) my hood latch sensor was in the closed state, regardless of whether the hood was open or closed. This was also confirmed by turning the wipers on and popping the hood - the wipers didnt stop.

Now the possibly interesting bit - I ran a full VCDS autoscan on the car, with debug level set to 2 (I was going to send Ross-Tech the info) and mid-scan (the scan takes several minutes), while the hood was popped up, my dash suddenly alerted me to the fact that the hood was open, and then immediately thereafter I received another message that my oil level was ok, and everything was full, and the low oil warning went off.

I've opened the hood almost 20 times in the last couple of days, and nothing had happened. Id had the hood popped open for about 5 mins this morning, and it was only during the auto-scan that things seemed to start working. I've since checked the hood latch state (both on the dash and in VCDS) repeatedly (I'm sure my neighbors think Im crazy), and the latch sensor is working every time. I'm wondering if the full auto-scan in debug mode triggered some sort of reset. Just theorising here.

I ran a full auto-scan (in non debug mode, debug level = 0 ) on Friday afternoon, so the only thing that was different today was the debug level being set to 2. Or its just complete coincidence and the hood latch magically started working again.
