Air Suspension/Springs for X5 with third row

[TexasMBA02]

Like many, my air springs are intermittently deflated when I come out to get in my car. Sometimes they reflate immediately when I start the vehicle and others they don't. I have a couple of questions -

1) I'm getting mixed messages about the springs that are required given I have the third row. I spoke to someone at Arnott and they said there's no difference and their website only shows a single model for the vehicle. A number of online parts dealers make no distinctions Other places (like FCP Euro) will say that it is for models with the third row.

2) Given the fact pattern (issues reflating immediately), I'm worried the compressor may also be having issues. Any guidance you could give here would be helpful as well.

Thanks in advance.

the deflating/inflating depends on the location of the leaks on the air springs, the air spring rolls over itself in certain parts so sometimes the leak might "close" itself up.

parking location might also play a role, if the tire gets "pushed" up or "dropped" down it might open the leak in the air bag.

I just replaced the air bags on my f15 hybrid, no 3rd row but it comes with air springs due to the extra weight of the hybrid battery? not sure about that one but it is a pretty straight forward process. The arnott website should give you the exact model you need. make sure you replace both if not going with oem.

There is no difference. Start with air bags, then check relay, valve, desiccant , compressor etc. All discussed in threads above.

Compressor is working fine if it's reinflating. Car has to be on to work (well activated when you unlock).

Replace the bags. They're the same no matter what configuration (dhp, 3rd row, etc). Replaced mine at 30k and I'm at 75k with arnott with no issue.
