Hi all: I just noticed a puddle of AHC fluid underneath my rear passenger tire on my '16 LX570. I recently had the pump removed and reinstalled by (Lexus) and cleaned (by me) to address a contaminated AHC fluid issue. Well documented here: LX570 AHC fluid change issue -...

I have the same sweating leak on my '16 LX570. Power steering reservoir doesn't show low, and it wipes on a towel as dark, not red ATF. Going online to source the part. Was going to go with 44410-60710, however it looks the part sites quote a different part for the '16 and later LX vs the '16...

So I was able to remove the pump out of the car today. I was able to disassemble it quite easily. While the tank did seem to have quite a bit fluid that may have had containments, I wasn’t able to see any goop blocking the 3 the brass ring “filters” on the pump head. I cleaned them anyway. Pump...

After reading a few recent threads on the 100 series forum this evening, I am too very convinced that contaminated fluid is the culprit here. Given that I have the bottle with the dealership markings on it, and I also have Lexus changing out the pump in a few days, I may have a better chance at...

Container complete with the origin and date sticker still on my garage floor after I got home. Anyone know how I would know which batch was recalled or had a stop sale on? Will call and let the master tech know to make an official observation on the pump when he pulls it out. Any specific area...

I guess we will see when I get it out. If it is I probably will call Lexus with my receipts asking for some compensation here.

UPDATE... First off hats off to this group to get back to me with a bunch of options/theories so quickly. Great community! Summary - I caved.... I am going to change out the height control pump for a new one at the Lexus dealer... So I am taking this one on the chin. 1) At first I started to...

If I take it home and I try again not sure what options I have left. Car is currently on low on all bump stops. Reservoir is completely full with new AHC fluid. And presumably the globes are pretty empty with fluid. The tech running the active test mode hasn't done anything. Not sure if...

lx200inAR - We just chatted with the master tech and he already tried with active test mode with the fill port open. No bueno. He also tried to add more fluid, but the reservoir is completely full now, since the car is on low, and I was above the max line when in normal mode. chriscosta416 - I...

I think they did that. If I leave the dealer and take this back for further analysis, would you guys drive on the bump stops? Car is a low rider right now.

I didn't try anymore since I originally posted. Let me see if the car is still on the stand in the back. He seems pretty cool. He may be willing to activate the test mode with the fill tube open.

BTW, tech stream is reading C1763 - " abnormal oil pressure for pump motor"

So I brought the car to the Lexus dealer today to see if tech stream could help and I am limited in time to troubleshoot. They put into test mode and the pump isn't pulling any fluid. And the pump is whining. They drained all the globes, so the car is on the bump stops with no ability to...

2.5L metal cans of AHC fluid.

I only got so far to bleed accumulator and DS front. I started the car after each bleed. Had issues right away after the first accumulator bleed. Never moved to other 3 corners.
