My 2008 Audi A8L, 3 problems happen all at once. 1 The dashboard warning telling me the Ecs/ Abs is disabled, at same this is happening the speedometer stops working it just drops to 0 and will not move. add to it, my backup camera suddenly goes out, all i see is black on the backup camera , then the Power steering goes out. Now i have taken the car to a specialist in European cars and he given a direct answer to my question of what is causing the Problem. And i don't want to take it to an Audi dealer. So i was hoping with you 49 yrs of Automotive experance that you can help me.
Should i just bite the bullet and take it to Audi or can you give something for him to look at.
Scotty does not revisit topics he has already answered.
Audis are extremely complex. An Audi dealer is very likely to take you to the cleaners. You might want to get a 2nd opinion from an independent shop that specializes in that brand.
Before I went any further I'd make sure to check the car battery and its cables, it's really the first thing I'd eliminate. You might get lucky - loose cables or a weak battery can create issuesNow i have taken the car to a specialist in European cars and he given a direct answer to my question of what is causing the Problem
Hey Scotty, you there ? i asked you a question.
Scotty does not revisit topics he has already answered.
he appears to look like he really doesn't know what the problem is.
so you need to find somebody who does. Unfortunately we can cannot diagnose such a complex problem through the internet.
I guess you are Ghosting me for something i said.
Who do you think is "ghosting" you?
What you need to understand is that you are dealing with a serious electrical or electronics failure in a very complex vehicle. On a car like that it is not feasible for most owners to do anything beyond a few simple checks, like wiring, grounds, and fuses.
Beyond that you need an electrical expert with hands on the vehicle to track down the fault(s) using professional-grade equipment, preferably someone familiar that make and model. This is basically what Scotty has already stated.

No.

You need to provide the code please. It's right in the instructions that were on your screen. Can't help you much without that.
I doubt the computer knows if the problem is in the sensor. Usually the diagnostics only tell you if there's a problem in a circuit (and a circuit is composed of many things, not just a sensor), or it will tell you that it is receiving unexpected information, which again can have many causes.
This is the problem with shotgunning parts at a problem. You just throw your money away, and you still don't know what the problem is. Proper car repair is: Learn how a system works, diagnose it , test, and narrow the possibilities down until you find the culprit.
Did you check for damaged wires, corroded connectors etc. like Chuck advised you a month ago?
Did you check your wheel bearings. If they're loose and sloppy then your speed sensors will read garbage.
I think you need a skilled mechanic.
Could the Transmission be at fault ?
Though granted that almost anything could potentially be wrong with an 18-year-old Audi, what is it that makes you believe the transmission is at fault? Were you experiencing shifting problems or slippage?

Well what answer did he give you? It seems you wrote that he gave you a direct answer unless you typed something wrong. There are so many things that could knock out as electronics from what problem inside the dash to a computer, failure to a electronic failure and even to the speed sensor on the transmission going bad. I'd have to see that one in person and scan it with my fancy scan tool
He told me that he has to look at the Car Computer, i took it to him exactly at the time it was messing up, so he could get the car when it messing up. And he did a complete scan,and he appears to look like he really doesn't know what the problem is. Should i just bite the bullet and take it to Audi or can you give something for him to look at.

Hey Scotty, you there ? i asked you a question.
I guess you are Ghosting me for something i said. I can't imagine what i said to make you ghost me but whatever it is let me be the First to say I'M SORRY !!!!!

What leads you to believe the CV axles should be replaced? Are the boots torn or the CV joints making noise?
The computer says that it's the speed sensor in the left front end of the car. But i changed the sensor already.
If a speed sensor is not working that would disable your ABS and traction control. Did you install an OEM sensor? Has it been tested? (Many new parts are defective these days.) Have the wiring and connectors been tested? Is there any debris between the sensor and the tone ring? Is the tone ring damaged? Is it integral with the CV axle, or part of your wheel bearing assembly?
As @imperator mentioned to you over a month ago you are experiencing complex electrical/electronic problems that really cannot be solved over the internet. The problems you are experiencing require hands-on diagnosis from an expert specifically familiar with that Audi model.
I replaced the speed sensor and it still gives the same problem, and to answer your question yes the boots on the axle are ripped. But i want to ask you is can a wheel bearing be the cause of my problem, on the Left Front where the trouble zone is ?

can a wheel bearing be the cause of my problem
If a wheel bearing is loose to the point where the wheel is flopping around it can interfere with the sensor readings. If the bearing is merely making noise and not actually loose yet, then no.
