Sounds like a break in MOST, fiber optic loop
Most common issues would be a fault with a module that is past of the loop like amplifier , bluetooth module , etc
Any sign of water in the passenger footwell ?
If you are replacing mmi panel or the borad only ... no codding required. Just plug and play.
But it might be worth taking the current one apart and check of there isnt any spilages that happened , its quite comon. The board is multilayer so trying to fix it would be near imposible
Yes. Its the pipe that supplies water to the washers . Its a bumper off job . There is a quick relase valve and fog lights cables so be careful when taking off the bumper
Hey
So cdya is an improved unit and more durable then bmk or asb
The issue is top tensioners that fail first with causes all kind of problems. You can tell by listening for a classic 2-3 second rattle on start up
The tiptronic zf6hp19a is great and probably most relible gearbox that audi made or if you prefer zf made 😉
The challange with the gearbox is oil changes . Audi claims the tranny is "seald for life" and will refuse any oil changes unless its part of the repair.
Lock up only happens around 30mph-70mph
Overall of you dont have any issues with the test drive it wil be fine
Regarding remap they work fine as long as its done by a specialist
Is the all road on air suspension ?
So i presume you have mmi3g
Ami on 3g system is easy to fit as there is no need to install a seperate unit. Buying a ami for 3g cable and connecting it to the back of the headunit is enough
So i have done the same mistake as you. My rear broke both sides so i replaced for new . Rear is higher then before.
I should have gone with changing all of them to -30 ebaih springs
The sline sport suspenion code is 1bv and its -30 mm to standard. But over time they will sag so if you replace rears only it will naturaly be higher...
I have mine wirred in on my a6 c6 to the heated windscreen sprayers . Its only on when ignition is on. But the only way to check is to get a multimeter and check voltage on each fuse with ignition on/off
If you have android phone then obd11 is best choice
Or for ios carista ( carista also works on andriod phones but obd 11 is better in my opinion )
If not then a vcds ross tech cable ( a laptop required)
