Builds eatSleepWoof's '14 LX

[eatSleepWoof]

Thanks, guys.

Also noted the dealer charged me $80 to straighten out my steering wheel (no alignment). A 5 minute job that every other shop I've ever gone to did for free. As nice as their service was, the work done so far is disappointing.

It sucks that you had to drive so far- sorry, man. You should make them send a (flat!!) tow truck and pick it up from you. Or better yet, make them refund the money and DIY.

If you have Techstream, check for c1743 and simply clear it. It's common if they bled too much fluid out without having enough in the res.
Also, You could easily pull a sample of the Ahc fluid from a bleeder to check the color.

did The battery disconnect work?
i guess if fluid level was low and you tried to go to high it might have hit a sensor error and this is the result. I will guess you don’t have a couple liters on hand.
its not a stock part so unless they ordered some ahead likely there was none to replace the old fluid with.

Unfortunately I don't have Techstream. Also running OSX, so don't think I can get Techstream installed here even if I did have a cable. Might have to find an old Windows laptop...

I actually asked the dealership to give me a printout of all Techstream values, (mainly to see AHC pressures) which they were happy to do for $50. Ugh.

I'll have to find a bleeder today and pull a sample of the fluid to see what's what.

The battery disconnect (25 mins) did not make a difference.

I'm going to call a few Vancouver-area Lexus dealers today to get an idea of pricing for this fluid, as well as for the AHC flush, and compare that against the dealer in Kelowna (which did the work).

Techstream can work on a Mac via a virtual environment. I don't think it will help in this situation beyond easy access to the codes. There may be a setting to run the pump, I don't remember. You can also check your AHC fuses, though I doubt that is the issue.

When you backlight the tank what is the fluid level? (Pull the access door directly behind passenger rear tire. Put a flashlight up by the spare tire shining on the tank. Read level from the passenger wheel well.)

 

[eatSleepWoof]

The fluid level is approximately 1cm above the max line. When started up, the car shows that it's in Normal height, but after driving 10-20m and attempting to raise it, (I do hear what I think is the pump running when I try to raise it to High) the error shows up on display, and the car shows that it's in Low height.

Called another dealer and they told me the same thing numerous folks have posted in this thread: fluid exchange takes 4L, cost is $40 CAD/L, and there's 1.5h of labour involved, for a total of $400 CAD.

Called my dealer just now, explained this to them, and asked them to send a guy over to pick up the LX and then bring it back when it's done. The service advisor did say he saw fluid being sucked out of my LX, so something was "changed." Also brought up the wrong fluid colour in the reservoir, advised them that there may be a re-levelling/normalization procedure to do after the fluid swap, and to definitely check for and clear any error codes via Techstream. They're figuring things out and will call back.

Let us hope that brake fluid does not come up. I worry that bleed and fluid make an unsuspecting tech think something they shouldn't.

You mean they might have put brake fluid in place of the AHC fluid? How bad would that be? "Entire replacement of all AHC components" bad?

Found this post which details how to change the fluid using only one container, vs 4. Maybe that's what the dealer did. Part number on the receipt lines up with AHC fluid part number. Hopefully the issues is as simple as clearing the error code.

That thread references an old part number, and isn't stocked by dealers. it's a single 2.5L metal can vs 1L plastic bottle.

Dealer is sending a guy over to pick it up Thursday morning. The waiting game begins!

Glad they are going to pick it up and try to make it right, but I wouldn't trust them to touch my rig again. Maybe you could get a refund, and have them send you 8L of Ahc fluid for free. We can help you get Techstream up on OSX and then you'll just need a $40 cable

It eats the seals. how much in 2 to 3 days? I don't know. . . . is there any nitrogen left in any of the 10 accumulators? I don't know . . . it's unfortunate all around and hopefully there isn't anything more here than an unhappy sensor or an air bubble or maybe some contaminants blocking up a line.

Good to know, thank you.

I'm pretty sure they put in the proper fluid. The part number suggests they did. Fingers crossed it's a simple fix on Thursday.

Dealer picked up the LX. Says they're having trouble fixing this... the error codes disappear when the car is shut off, and re-appear after you try to raise it. They'll call back to tell me the specific error codes they're seeing.

I am sorry. Did you ask how many liters they used for flush?

I would think you re correct that they used the right fluid since part number is correct on receipt

I didn't ask. Definitely not 4 litres. I've found posts in the 100-section that outline how to do an AHC flush using just one container of fluid (vs 4), and while I don't know whether that method is applicable to the 200-series, I suspect that's what they tried to do.

Didn't hear back from the dealer today, despite expecting to.

I suspect they will bash their head against this for another day (tomorrow) and then tell me my AHC lift (which I disclosed and discussed with them prior to this problem) is to blame and there's nothing they can do. Will find out tomorrow.

I sure hope not. If you used a 'sensor' lift and didn't extend the bars or anything you are still in stock oem condition.

Heard from the dealer. They're having no luck. Did another full AHC flush - no change.

The code they are getting is C1763.

They have reached out to specialty Lexus Technical Assistance (part of Lexus) on the east coast of Canada and are waiting to hear back. It's already pas 5pm on the east coast, so it'll be Monday before we hear anything.
