Continued Driving possible: Chassis

2018 750Li

Front driver side doesn't want to stay aired up. Had the strut looked at and there is no leak. I can reset it and drive and it will be fine for a while. Once I park or let's back down. Sometimes while driving it will do it and I have to stop, turn car off and reset again.

I dont know how the strut was checked, but if the codes were not read then I will go on assumption that this check was not very thorough. Diagnosing the leak in the strut assembly without specialist BMW equipment cant be done accurately, unless the leak is obvious. If there is a check control message, then there will also be a fault code entry that will help with further diagnosis and provide service modules (in ISTA) to diagnose further.

It could also be a leak in the air line or faulty valve unit. You really need to hook it up to proper diagnostics system to go further with it.

Thank you. My mechanic knows the cars, did all the diagnosis be could. He let the car run and sit while working on my other cars. Warning never came on, and car never lowered. He couldn't find any leaks, even while on the lift. Hooked it to his computer and violet connect because he doesn't Ferber the bmw system. Wasnt till I got 15 minutes down the road the warning can't on. We stopped, front left littered back on. If I turn the car off completely and restart it, it works just fine till I drive for a while. I can park it and it will be fine for a couple hours before it lowers.

Be said I'm gong to have to take it to bmw for them to connect to it.

Keep us updated I want to know what the solution was

[EagleMitch2]

I will. I have to take it to get checked still. Does it now only when it siyd for a period of time. But airs when the car is started and hold just fine.

I would really suggest you have some small leak in air system. When is your engine on, the compresor is able to delivery enough air to compensate air leak and keep your car in OK position. When you park your car, compresor is not
working and you are slowly losing preasure in system.

The easiest way is soopy water - when you see bubles, this the place where leak is.

This might be the same issue that was the culprit to my issues. Shocks may be wearing out. It may be best to hit the dealer and get that changed under warranty. I made a post about a similar issue a week ago but mine was much worse.

I would but I'm out of warranty. Lol

There’s an extended warranty on all g12 for chassis/air suspension to 80k miles or 8 years

Just go to any dealer and show this to a service advisor, they HAVE to honor it.
But you need to make sure that all shocks are original and nothing is aftermarket otherwise they won’t take it in.

[jlin101]

the extended warranty applies to the strut assemblies only; the "erectile dysfunction" may be due to leaky air pump which ex excluded from the extended warranty.

[EagleMitch2]

After reading the warranty, the problem issue they explain is exactly what is going on.

Keep us updated on taking it in, make an appointment asap and get it handled, you’re so close to that 80k. They might even give you a sweet loaner if you ask for something more than a 3 series.

[EagleMitch2]

I have an appointment for this Friday. Hope no 3 series. I can't fit in those.

Happy for you, hope they end up changing all 4, and they’ll give you an alignment as well. You might even be able to get an i7 loaner possibly, at my dealer they told me I could if they had it available but someone snatched it up before me.

[EagleMitch2]

Nice

Keep us posted, EXACT same thing just happened to my 2018 740iX (see top post too).

[Tony_The_Hammer]

Just had mines fixed on my dime. Same error. That right rear strut is next so have them change it too. I bought the ebay replacement strut and new pump. Paid $1150 with an oil change. Paid $700 for the parts.
