Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.
Ok, so you're got yourself a pretty extensive list there
and expensive as well
the water/fluid damage is a big deal
MMI replacement is about $1400
Yes, extensive. I've tried to find other answers but you seem like the best bet from what I have heard
thanks for asking for me :-)
The heater/coolant smell thing is worrisome, since heater core replacement is quite pricey
the biggest unknown here is the potential damage under the console trim
back in a moment....need to step out to the shop
Can you get the parts for MMI direct of from wholesaler and install yourself? I have a friend who is a certified LandRover tech who would be able to help as opposed to going to Audi
Or search for a wrecked car for parts?
Ok, so first the MMI question. I would not install used since they're problematic at best. Installing a new one does require dealer reprogramming
Same with the heater core....meaning, don't go used
Too big of a job to chance it
yeah, probably just wear a sweater. I live in so cal
At some point though, since coolant flows through them full-time, there will be a larger breach, which will cause coolant to come into the passenger area
ok. I've had that happen. It only smells now when it is blowing hot
is the mmi under the center console?
Ok, got it. Let's talk steering hose
The MMI is basically the multifunction display
steering hose retails for $375, and takes about 1-1.5 hours to replace
only use Pentosin CHF11S fluid
I've found them online from non-dealer supplier for about 200. Safe to use non-audi repair facility if they are reliable and trained?
sure, no problems there
Anything else I can help with today?
the brake light and anti-lock brake? Are they MMI related? and how can I source an MMI without going through audi if i find someone who can program it?
Oh yeah, I see that now. Ok, anti-lock and brake light being on. Scan first using an Audi-specific scan tool such as vag-com/VCDS. A standard OBDII scanner won't communicate with the brake system
this will not be related to the MMI problem
Assuming the intermittent oil pressure light is a sensor, what am I looking at to fix it?
You can likely buy a new MMI unit through an Audi online parts source like ECS Tuning or similar...
but dealer programming will be needed unless you can find someone with a dealer-level scan tool
OK. I know those are elite
Oil pressure light would worry me
A test using a mechanical gauge threaded into the oil pressure switch hole is necessary here
and finally, the parking brake faults. These can also easily get over $1k very quickly
scan will be needed there also
it leaks oil so I may need to drop pan and replace seals and gaskets anyway. Would that be a good time to investigate if it is sensor or pump, etc.
possible motors, and/or damaged electrical harnesses
yes, that would be a good time
So, if I go into a dealer with this list what am I looking at for a diagnosis? What should I do, I guess I am asking?
I would strongly suggest finding a good independent Audi specialist......can you give me an idea of where you live?
Altadena CA. Near Pasadena
Ok, this is a bit of a drive for you....
give me just a few minutes. Sorry
Ok, you will need to go to Van Nuys. I know it's a trek in your traffic, but this guy is the best of the best
OK. No problem.
Talk to Mike. Tell him Bracketracer sent you
Bracketracer? What class?
LOL...it's been a while. Mostly local, outlaw tracks around East TN, and some IHRA Pure Stock stuff in the 90s
cool. well thanks a bunch. If you ever need some crusty demons videos or merch I'm your guy and I will hook you up. crusty.com. Free-style motocross pioneers. You've got my phone and email.
Nice. Thanks for the hookup!
And with that, back to my shop to crack a whip :-)
been a pleasure and good luck with it all
Thanks. Take care.
