Did I get a good deal on this 650i Gran Coupe?

[Opie55]

Yes, T is TU. There is no T.

Those are BMW 741M wheels, I believe they started coming as options on X5's and X6's in 2020.

Yes. The last one is the vent lines I told you to have them check for. Those can fail without you knowing it. If the injectors or high pressure fuel pump fail you won't need me to tell you. I've had no issue with those.

[Opie55]

If you are getting the car inspected at an actual BMW dealer, ask them to tell you the actual "in service" date. That is the date the car was first sold and the warranty began to run. That way you will know when the ten years expires for these four items. You may be past 10 years already. My car is a 2015, but it is a very early production 2015 and its in service date was June 25, 2014. If yours was an early 2013 you may have passed 10 years sometime this year already.

OK sounds good. I think it was first sold in the middle of the year. It's on the carfax report, but I'll definitely ask them. And yes I'm going to a bmw dealership service center. I do have a local mechanic that works on my X5 but I want to get BMW's take on the car and have the dealer cover any repairs it may need. The dealer offers a 100 day warranty so I'm trying to maximize that

[Walt White Coupe]

I've had the vent lines and the high pressure fuel pump replaced under this extension.

Mine is a 2013 with 37,000 miles. Built Jan 15, 2013 so my warranty is almost over.

[Zwmack]

Actually just used the Vin to find out the production was 9/2012. Might be too late 😭😭😭. Hopefully the previous owner took advantage of the repairs offered by bmw

And if you want, we can tell you if you have the old or new vent lines before you go for the inspection so they don't BS you. On top of the engine you have the big decorative cover. It just pops off, but pop it carefully so you don't break off any of the 10 year old heat-baked posts. Just pull it up at the front an inch or two off the two posts there, then slide your hand under the middle of each side for those two, and then at the sides near the back for the last two. Then just post up a picture of the front half of the exposed engine. The lines sit right on top just behind the alternator and run from side to side on a narrow metal "tray." We can tell by looking if they are the old or new style.
And while you have the engine cover off, unscrew the black cap on the little coolant reservoir that is dead center at the front. Look to see if the coolant is up to the obvious "full" line. Your car has two separate cooling systems. That secondary system cools the two engine computers and the two "charge air coolers" for the turbochargers - those two aluminum "boxes" on either side of the coolant reservoir. That coolant system often gets ignored because it has no level sensor or warning. And you are wondering why I would tell you to do that when you are paying for an inspection. To which I reply "ha, ha, ha." That reservoir was bone dry when I got my car, and mine was a CPO car that supposedly had just undergone a detailed inspection. And one of my air filters literally had a fist full of hay in it. And my main coolant system was more than a quart low. That "I don't really car about your car" mentality is one of many reasons I DIY everything.

Build date is irrelevant. It's the in service date. Your car may have sat unsold for a while.

[Opie55]

Personally, if your regular place that knows you and works on the X5 is a BMW shop and has the BMW scan tools, which they must, I'd have it inspected there. A dealer is not going to give you any special "take" on the car. Their techs are not special people. They just charge more to be not special at all.

Really good information. As soon as I get the car I will definitely take pics of the areas you suggested and post them. I would like to take it to bmw only because they will be able to pull service records and they are a certified shop for the warranty with the dealer I am purchasing the car from. My individual shop isn't.

OH wow. You can see a difference in the hosing. The first looks like cheap plastic, the second looks like sturdy rubber. I will take a look at this as soon as I get the car. You guys have been amazingly helpful.

I took a screenshot of the engine bay. Is this the cap for the coolant reservoir that I circled in red? Just trying to get the landscape of the engine in my head. Used to seeing the straight 6 in my x5.

[Zwmack]

Also...

Ive found videos that say cold air intake systems help keep the engine cool and improves long term durability. Is this true? I found the video below, he's working on a 550 but same N63 engine. Thoughts? Does this really help with engine longevity?

https://youtu.be/1RMhH8TN3Ws

[Walt White Coupe]

No, if you want to prolong engine life and reduce maintenance, stay out of the turbo chargers except when needed.

The main engine cooling filling cap is the cap in the lower right hand corner.
And here is how you tell if it's full or not:



And I think removing the top engine cover and leaving it off helps keep the rubber hoses cooler and prolongs their life. Seems to me the cover just traps hot air.

Hey guys
I'm new here and new to BMW cars.
Loving my used 640i but admit a little intimidated with the simplest problems that can happen with these cars called the ultimate driving machine. Only thing wrong with the car that I know of is the steering wheel adjustment. Is it possible that a fuse is the problem or something worse. I can't get to the fuse that I suspect because it is behind the glove box. The small access door inside the box is to small for me to reach the fuse. Can the glove box be removed easily to get the the fuses? Ive tried all the owners manual approaches.

[Walt White Coupe]

Beemerdawg71,

You should start of new thread with "2016 640i convertible power steering adjustment" as your title. More people will see it.

Yes, that is the cap for the secondary coolant system I was talking about. The main coolant system Walt is talking about is the cap near the firewall next to the engine on the driver's side.

[Opie55]

EDIT: I was confused when I typed the below. I thought you posted the first engine bay pic and it was your car. But it may still apply once you check yours.

So you have the old style lines. So now without moving them look at the tray they sit on and see if there is any oil. If there is, then they are a cracked. They get very brittle and just looking at them funny will break them. One day mine were fine and the next time I looked one was broken in half. If yours are not cracked yet, BMW will not replace them even if you are still within 10 years. You could proactively do it if you want. The car will usually still run fine if one breaks. I could have had mine done under the warranty but did it myself because that's how much I hate people touching my car. The lines are actually pretty complex and include the PCV valves. The lines cost like $325 and it was a couple hours to swap them out. I'm guessing a dealer at inflated parts prices and labor would charge you $1,000.
