Almost a year with nothing major. Power steering went out yesterday at a store parking lot… No oil anywhere. Just a grindy noise from the pump. Looking at the worst case scenario of having to replace my power steering rack…
Can you even do that without removing the engine?
Hey man. Did I understand correctly that you replaced the power steering pump without dropping the engine?
Would you say a pro mechanics shop should be able to attempt it if I tell them its doable? They looked up the official audi documentation and it says to drop the engine.
I definitely changed it without dropping the engine im trying to remember how I removed it its been a while. I’m pretty sure I removed the subframe to have some room and i had a hydralic jack holding the engine up and I removed the driver side axle because it was blocking the bolts holding in the pump. I did It on the floor in my driveway. Honestly if I went under the car and looked at it. It probably would come back to me but I’m certain I removed the subframe
Thanks bro. The shop was able to change it in 3 hours which kinda amazed me a bit.
What had happened:
I had previously installed a Meyle PS pump as a pre emtive strike. Bad idea.
The problem I now had is: this spline axle or P/S coupling had stripped on the engine side.
I suspect the reason is this:
The Meyle pump was intact but it was soooo damn hard to turn by hand. The oem was way easier. Imagine it at 700rpm and at 130bar. That shit is not good. I hope the oem would work, and that the engine side of the equasion isn’t cooked.
MOT inspection (katsastus) once more flying colors and a friendly engineer said he enjoys the v10 in comparison to all the elextric bs lol
I’m glad to hear it all worked out!
Trying to figure out whats wrong with my sai system, cold start vacuum leak so bad it loses power braking and wants to run into trees and houses. once cold start cycles off its back to running perfectly. Any common failure points in the SAI system that would result in a vac leak?
There are a lot of check valves and off the combi valves there are the vac lines… If you can either remove or you can smoke test out the SAI system by putting the smoke into the vac lines going into the valves.
Replaced my oem? xenons with osram nightbreakers… Parking garage test doesnt show a massive difference with a control camera test. Gotta go for a ride and see if there is any.
Has anyone ever successfully retrofitted better headlights (LED or ANY upgrade at all?) on an S6? The problems is: all S6 have AFS, and you cannot code it out apparently, because the DRL:s need it to exist.
The thing is: my S6 has the worst headlights ive ever seen on a car, and that wont do for a car with 400+hp and a perfect winter driving platform. I gotta see where im going lmao
A few new problems have risen:
Any ideas?
Post a VCDS scan.
Regarding the rough cold start and weak brake assist - your intake part P/N: 078133753A might be broken. I don’t know whats the english name for it and i don’t want to butcher it. It has a membrane inside, and it can get stuck.
Also, i would do a static log for both throttle bodies, to check if they work properly. Start logging, and press the gas pedal slowly to the floor, than release. Repeat 2-3 times.
Also, have you checked your SAI system as justincredible suggested?

nothing else but just these, edited irrelevant stuff & modules
I did the throttle body adaptation and now it wont stall when revving.
Also just did a drive with mafs disconnected, cant really feel a lot of difference. sadly i was looking at the short term fuel trims in the wrong place and didnt take note if disconnecting the mafs did anything to them. I reset the adaptations and found the short term trims go to -25 in all 4 banks
All of these can be associeated with flaps stuck.
Fuel trims can be due to faulty injectors. Have they ever been replaced, or checked?
VCDS findings as of now:
Its like the engine thinks its under load or sth. On idle engine says 24% load tho. Going through the vacuum system and I noticed the T-shaped eventuri pump was broken in half. Ordered replacement.
Throttle body readings showed bank 2 TB as a little weird and blippy. Switched them over, and neither felt blippy anymore. Connection issue?
Went to start engine, to find it developed the loudest squeaky vacuum cleaner whine. Whine went away when removing oil cap. I didnt even touch anything vacuum related but I guess PCV diaphram just went randomly. Ordered replacement.
Waiting on parts for now.
Im a bit on the fence about the injector thing because all four banks are thinking rich rich rich all of the sudden. I will do injectors anyway, but my emissions and fuel economy has been alright.
The previous owner randomly changed a couple injectors with oem hitachis but I think they were just chasing some random problem non related
If all banks seem to be similar-ish to each other (remember, there are 4 banks in V10 for injectors), then i would say it’s not related to the fuel system, rather vacuum/intake/carbon buildup
