All issues and niggles with the B9 RS4

Post by PieterZ » Tue Dec 04, 2018 9:13 pm

As said in the title, maybe worth making it a sticky.
I personally have had a damaged seat due to a faulty installed beltbuckle.
Next was an open stuck thermostat.
Today I came home from work and noticed 2 damp headlights...
I’ll have to see what that brings in a few days.

Other people posted that the DRC issue has been at it again too, and a de-attaching carbon fibre engine cover seems to be the last hickup so far.

Please post your experience with hickups or faults so other owners know what they may expect in the future.

With interruption of steady production runs this past 6 months - from Sumner shutdown (nearly a month?), to the untypical impact of WLTP testing delay (more than several weeks?) and now end of year production stoppage - these being just stoppages that public know about - then it’s ‘almost no surprise’ that there will be more gremlins during restart of production vehicles.

Clearly it is not the only factor, and many issues being raised come from vehicles built long before this Summer but when it comes to “assembly build & quality” of any product, in spite of existence of concrete work instructions for the lines and multitude of Quality Control mechanisms, it is widely acknowledge that errors and quality temporarily drop a few points after holiday or extended production stop periods. There’s no reason to believe this doesn’t apply at Audi AND their Part Supplier base.

Just an opinion, everyone has one:), but all these production start & stop interruptions cannot be good for overall Quality :-((

Mine is from may 18th if I remember correctly.
You've got a point with the interruptions.
But damp headlights, these are also found on the regular A4, minus the spacer grills.

Mine is from a few weeks earlier. Carbon cover aside, I've had no issues and the car feels like it is build like a tank. I also run a 2006 A6 shed though, which feels even more of a tank at 170k miles. Hopefully that same build quality has endured for the past 12 years, but who knows, time will tell. I'm anticipating being one of very few owners of my car.

The only other thing I've never really got to the bottom of it the car being delivered with 45 miles on the clock. Even the PDI report has that mileage noted on it, so I understand it has come from factory with that mileage. Unless a dock hand has been doing doughnuts on the quayside... :bash:

RS3s also come with about 50m on the clock from the factory. Afaik the RSs get more testing at the factory vs standard models.

On a rainy day my headlights look like this, anyone else with the same issue?
It disappears after a short while when you drive, but imo it is far from ideal.
Second picture is extreme. At night when I came home, it rained.
After a short while the headlight fogged up inside on the exact place where the raindrops were on the outside of the light.
That part of the lamp cooled down more due to the raindrops on it and thus caught the humidity in the headlight.

I'd be going back to the dealer and having a discussion because that means there is water moisture in there with all the electrical gubbins - sure to invite corrosion and premature failure.

I've contacted them. I was told light condensation was normal.
Only thick droplets was not ok.
Usually it isn't as in the last pic. That happened after a long drive, and ot was still raining.
Condensation appeared where the rain sat.

Do you have condensation on yours when it rains?
They replaced the thermostat and removed the bumper, may that have caused it? Are the lights attaced to the bumper?
I never noticed this before, but it hasn't rained a lot before either...

Anyhow, I have an extended warranty should <beep> hit the fan after a few years.

I had a bit of condensation in mine just one time then never again. If it gets colder I guess it may return.

Mine stay dry - that said it lives in a dry garage with an electric radiator (used to keep the motorcycle warm in Winter) on a time-switch barely a metre away so I'm not really a good example.

Correct, mine's 24/7 outside.

Thanks for the reply Terminator_X. Over here it's around 5°C and rainy.
I just checked, lights are free of fog at the moment.
I drove 2x about an hour yesterday, lights on. Maybe the heat dried it out fully now?
Still something to keep track of.

Yes on my 1985 Vauxhall Nova GTE, what a load of :dung: at least the dealers are consistent no matter where you are in the world.
