The system they use in the W12 is very smart to avoid wear risks, it alternates side to side since each side of the engine can run as a VR6 engine in its own with the other head having all valves open unlike in the 4.0 where they remain closed to perform an air spring type effect. Both banks are kept hot and happy and are used evenly, it takes extreme advantage of the fact the W12 is literally two VR6 engines and just runs them as singles.

Even my engine has two separate ECUs, fuel systems, air intake systems, throttles, coolant sensors, knock sensors, crank/cam sensors, etc for each side of the engine. It's two twined engines like how most V12 are setup as twin inline 6s

It's much better than on the 8 with it's always the same, set of 4cyls shut off with cyl 5 (drivers side front most) receiving a lot of extra wear due to temperature imbalance. You can easily see it on the plug when pulled on any 4.0T car.

Thats the point, the Lexus system doesn't keep the car centered in the lane in as confidence inspiring a way.

Thats just not true of a good modern system.

Right so now that I've had the time.....

Oil leak is still unknown since I ran out of time yesterday but it's not front main or PS, it is engine oil and while I don't think it's PCV I'm hoping it is since that would be easier than anything else.

Suspension is somehow totally fine other than sway bar bushing noise, that's a very well known issue with these but it's easy to fix to the tune of the wheels can stay on.

Trans is a ZF8......nothing wrong there.

Engine needs to be carbon cleaned, there is quite severe buildup and while there are no running issues it's probably costing me 40+ hp.

One of my left hand exhaust shields are loose, only makes noise when the car is in motion at exactly 2400-3000 rpm at light throttle. By far this is the 2nd most annoying issue it has.

And the number one most annoying problem is now isolated and slated for repair, I was correct and the dust cover for the sub was indeed loose....that is it is loose to the point it's just not connected entirely. I found it this way when I got the grill off, funny part is the manual claims non-destructive methods of removal are impossible but clearly it's a skill issue since I had no problems.



I don't think it's supposed to be like that....

Skill issue.

Very interesting, had no idea it was running two Engine Ecus and dual fuel pump setups.
I'll have to look into it now cuz I like to know if it has another 3rd Ecu acting as a "wrapper" for engine management and control of the twin Engine Ecus, pumps, etc.

Really hoping Striker doesn't have to remove the back seats as shown in the pics above.
That's a lot of work to pull a speaker.

Maybe access to back side of package panel from the trunk but not likely based on drawing above.

Oh it's out lol, the manual is usually incorrect in many cases if you have done things like this enough and know what you are doing. German/high end cars in general are like this, if you are skilled and more importantly experienced you can do a job that says "remove engine" by only dropping the whole subframe slightly for access.




Now I'm just waiting for the E6000 to cure, even without the sub this is an extremely impressive sound system. Better than anything else I've owned or heard in a car outside of a Maybach.

I hope you make a killing in your business.
Flat rate book time says what it says so the tricks to save time is money in your pocket $$$.

Indy's are the way to go for Euro cars and I was lucky enough to live near a good one.
Just thinking you may be the only guy who can work on Audi's if in a rural area.

Though you would like this video being a shop owner especially if you work on foreign cars as I imagine good help will be hard to find.

Oh yeah, if you know what you are doing you make over 120-140 an hour as the owner EASY. To top it off that's still undercutting anyone else by at least 30% so customers are astounded in a good way.

You are correct that I'm the only guy around who is able to work on many types of cars, I get dealer reject work that they can't figure out from time to time as well.

Good video, I personally don't really plan on adding help/expanding since it would become so much higher overhead and like you linked it's nearly impossible to find good help/high enough skills these days. Cars have gotten too complex and if you aren't cutting edge you are screwed, it's not the 90s anymore that's for sure. It's no wonder the industry is dying lol! You really do need to pay the skilled guys 100+ an hour for this to be worth their time but dealers/shops are stuck in the past when cars maybe had 3 computers.
