So.... I figured out where the leak is getting into the car. The driver's side corner sunroof drain is the culprit. With the sunroof open I used a squirt bottle and sprayed some water into that drain, and low and behold the water started spewing onto the dead pedal. Why in the hell would the sunroof drain into the car? Is this some more awesome Brit/German engineering (like putting the starter INSIDE the transmission)??
Second thing... The driver's side EGT sensor was replaced with a brand new OEM sensor, and now that code is gone.. BUT, the car still has a misfire. All codes were cleared but random/ multiple cylinder misfire code accompanied by cylinder 10 misfire code was retrieved after it was test driven. It still lacks power, stumbles and sounds like garbage. Although the CEL never flashed like it did before.
More testing to come, but interested to hear ideas...
There is a special place in hell for people like Houston Direct Auto.
Anybody want to buy a 2009 Spur Speed?

Have you or anyone else tried to use the Autel scanner? The Autel is bi-directional and allows you to operate different components individually. Sometimes when I'm searching for codes / issues I use a different scanner and get additional information that helps diagnose problems. Also, have you flow checked the injectors? Dirty injectors will cause misfires at random as well. Good luck in your search.

As mentioned before, the scans are being done with a Ross-Tech VCDS HEX. So they are very detailed.

Yes indeed, I read that. My point was if you have access to another scanner i.e. Autel (or other) I would give it a try. Perhaps anyone you may know that works on exotics; Lamborghini, Bentley, Rolls Royce, BMW etc,. may have one. I own several scanners, some are supposed to be 'the best' however, when one doesn't provide me with a viable answer I utilize another and It gives an entire different aspect of answers. Codes don't always tell you the problem -- they are sometimes the byproduct of other issues and another scanner may identify that for you.

I may try HPTuners and see what I can log, that way I have data to interpret. I am interested to see if I can find a "misfire graphic" or individual coil data. I sure can on my GMs. I have the full capabilities of a GM Dealership MDI2, plus HPTuners MPVI-2 Pro Suite. I am starting to think fuel Injectors need some attention...
Did some datalogging with HPT today..
Riddle me this... How does a twin turbo 12 cylinder 6 liter move less air (MAF g/s) than a 4.8 liter NA Chevy V8?

Not too familiar with the HPT unit. Although I do know it will utilize the PIDs of the last known vehicle used in the software unless it's been cleared and reformatted. Question: is it possible it's not formatted for reading the W12 cylinder engine and therefore only giving you an erroneous number? Again, I'm only guessing.
Can you get your hands on a vehicle specific, BENTLEY scanner? See if you can locate a friend or shop that has the Autel scanner. It will give you everything you need to know SPECIFICALLY about your car -- Not some or most codes, but specifically almost all parameters you need.

HPTuners will only populate and show data which is actually there. So the likelihood of something erroneous is not likely, as it wouldn't even populate in VCM Scanner. I only have access to GM MDI2, Ross-Tech, and HPTuners. How much does an Autel cost? Bentley of Nashville quoted me $500 for diagnostics, and they are an hour away.

Interesting, not sure if I would own a Bentley w/o owning an Autel. Actually, I own several exotics myself, including a RR Phantom and GTC Bentley. The dealer may give you some feedback but $500.00 for a diagnostic scan and no repair, I would invest -or- borrow the Autel. It covers most vehicles but it's not cheap. I have the MaxiSys MS906BT. They cost around 1,200.00 U.S. but well worth it!
BTW. I just did a repair on a 2015 Lamborghini Aventador and the dealer scanned it and said no codes. The customer brought it to me and the Autel picked up 13 fault codes!

I own a pile of badass American cars and trucks, therefore never needed an Autel. I will check out the part number of Autel you mentioned. I do not have anyone close with one to borrow. However, I did just get an email from HDA saying they may send a truck to pick it up.... So we shall see what transpires...

That's great news if the dealer will remedy the issues. Still if you're going to keep it...
Yes, I own many American V10, V8 cars and Trucks as well. Regards, Doug
As you will know the W12 6l engine is basically 2 3l v6 engines and to all intense and purposes utilise their own ecu,s .The inlets , turbos and exhaust are also separate.
Is your scanner just reading mass air flow for 1 bank and not the 2 combined totals added together. If your V8 4.8l has a combined inlet and uses a single mass air flow then it will be measuring all the air flow to both banks. Which is more than the Bentleys 3l single bank flow.

That is a good point and would make sense. And since HPTuners was not intended to scan or tune these ridiculous cars, I do assume the single MAF channel is the case. Thanks for your insight.
