Hi everybody,

I was just wondering what the cylindrical metal object is for under the left side of my 2010 LR4 (see picture). Its only on the left side and extends for as long as the drivers door. (German LR4, left side is driver). Its attached to the chassis but its hollow, looks like a storage tank for something.
There are no stickers on it and doesn't say in the handbook either.

Incase you need to know its the 3.0 TDV6, HSE, with air suspension
Anybody know?

Thanks

 

Looks like the high pressure storage tank for the suspension system.

 

Thank you for answering. I was thinking something for the air suspension.

The reason i asked was because I just got my tires exchanges and the shop had a car lifting thing. They placed rubber cubes on each corner of the chassis to lift the car. However on the front left they placed it under that tank. Not under the chassis. Now the air suspension is being weird. Its not going up, thinks it in off road height but its in access height where i put it down to to test.
I looked at the position of these rubber blocks, and in the manual of the car it says to strictly only jack up the car at the designated points, asked the person in charge and apparently they always do it like this and everything is ok etc.
When the wheels where fixed again the car was lowered, front suspension went down to normal level once the wheels touched the floor and the weight of the car forced the suspension to how it always is. However the rear did not go down. We drove it out, played with the up and down buttons and it eventually lowered itself.
Now its playing up.

 

Definitely not how it should be lifted, however, I don't see that causing your issue, as if the tank were damaged, you would not be able to raise normally at all. However, it does appear that the rear rubber blocks are touching the plastic casing for the compressor, and valve block. If they managed to damage the valve block, or air supply tubing that goes to it, that could definitely cause your issue.

 

thanks for answering

Yeah exactly

Well thats the problem, it doesn't raise to normal anymore. its stuck in access height right now but on the 4x4 info screen and the selector buttons it says its in offroad height as that is what I selected. Occasionally it gets the rear up a little bit. But only minimally. It gradually got worse to know not functional.

The rear rubber blocks were definitely on the chassis, I checked all others. Good to know thats where the compressor etc is. Back left, infront of wheel, gotcha But now that you said it I will check on the car for marks. It was very dirty and I can clearly see where the blocks where on the tank (the dirt was scraped off). So I will check at the back, maybe you are right and it was. I was sure it was on the chassis but maybe not completely.

Could there be any link to the rear suspension not going down after lowering the car from the lifting thing??
The image attached is from how high the rear was after lowering, the front was at the normal height (about 10cm between wheel and wheel cover thing)

 

OK, if the reservoir is cracked, which lifting the weight of the vehicle by it could easily do, that could be your issue. I misunderstood what was going on at this point.

It would probably crack near it's attachment point under this kind of pressure, which is at the top of the reservoir, kind of difficult to see. I would get it taken to a Rover specialist, and have them confirm the issue, and deal with the tire shop as far as paying for it.

 

One very good reason to pay for repairs with plastic, so that charges can be disputed and the credit card company resources put to work for you. AMEX has saved me, been there, done that, got the T shirt.

 

That would make sense.
I knew there must be a second place where something is attached. It being on the top makes sense, I you can only see the side and bottom.

Thats what im going to do in the next days.
Im going to make them pay for it.
Guess its and expensive repair.
I havent payed yet at all
my third car has an appointment to get the tires exchanged there next week. Paying them all together.
But I will definitely pay with plastic

thanks for answering everybody.

BTW, is there a connection to the back suspension not lowering at first while the front went down to normal. It stays at full articulation (if thats what its called) about 10-15cm higher then off road height. See picture from my last post.
Thanks

 

The rear not lowering is strange. That is the reason I was wondering about the rear lift point. However, if there is a problem with the system, it can do funny things sometimes.
With this scenario, you may need to have it diagnosed in person, and see what is going on from there.

Can you take a pic of the 4x4 screen so we can see what the height sensors are thinking?

 

Ok, yeah it was weird, never saw anything like that before.

The screen is showing its in access height while the buttons are doing: offroad - blinking, arrow up binking. middle line highlighted. Been like that for a while now.
Some times just the offroad light is highlighted.
I haven't driven it yet. Scared to do so.
If no air is in the system, is there still "normal" suspension to hold up the car or would it be sitting on nothing, so no suspension travel?

just checked again. The buttons are showing its lifting. The screen shows its in access height but says it lifting.
Nothing is lifting. Seems like no pressure or whatever causes it

I checked the rear left part.
It appears the rubber block was partly placed under the air compressor shielding.
maybe a third of the block was under the compressor, rest under the chassis.
Could that have caused any damage?? I dont know how far the shielding can be pushed in / flexed etc or if there is space between shielding and the compressor itself.

Right hand side of the picture is that block. You can see how its partly under the compressor on it.
second pic, you can see about 5cm of the bloc on that corner is under the compressor. As the chassis bend around it at that spot more of the block will be under the compressor on the other side.
