Air Suspension head scratcher
The exhaust valve stuck open doesn't guarantee the vehicle will fall, once the springs are pressurized to reach the desired ride height each individual air spring is then isolated from the gallery (per a valve for each corner, 9/10/13/17 in your image). If each valve had a small leak but... -
Air Suspension head scratcher
Keep me posted, if it does fall lets keep an eye on the fall as a function of time, so measure it something like every 4 to 8 hours. -
2012 LR4 Reluctant to lower from off-road suspension mode
This evening I managed to get the GAP iiDTool connected! Bear in mind that a local shop confirmed with their scan tool that the RLM ECU is flashed for an AMK compressor I was pretty surprised to find this with the iiDTool: Given the two compressors have different characteristics this has the... -
2012 LR4 Reluctant to lower from off-road suspension mode
To continue with the saga in the hopes that this will help folks that get to follow... This weekend I removed new AMK compressor and checked all electrical connections very carefully; this involved a continuity test on all leads while also moving them around to check for a breakage, everything... -
Air Suspension head scratcher
Just one other thing, other sites mention removing the 20A fuse 26 to disable air suspension. I don't know the difference at the moment but it might be worth a look. -
Air Suspension head scratcher
I really feel your pain, I'm going through a different but also annoying suspension issue... Thinking out loud... I suspect you're going to need to think outside the box! If you open the middle solenoid valve all that does is connect the gallery (the air in all the pipes) to the reservoir... -
B1163-15 code - heated mirrors
I went with the cheap option on Amazon: https://smile.amazon.com/gp/product/B073LZCX6D/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1 One key issue is that the pins are rotated 90deg so I had to bend each pin ever so slightly so that the two cables don't make contact (which incidentally they... -
B1163-15 code - heated mirrors
Also wanted to run calcs on heating wattage, so, W = V^2/R, so with a resistance of 6.9ohms (reported on page 1), we'd have (assuming 12V supply): W = (12 x 12)/6.9 W = 20.9W This is a reasonable amount of heat! -
B1163-15 code - heated mirrors
Thank you ftillier - You're bang on the money with the instructions (it's super simple as well), here are some notes/images for those that follow, first put the mirror to this position (pointing inboard): Gently pull it in the direction of the vehicle (horizontally) by putting your fingers on... -
B1163-15 code - heated mirrors
Thank you, will give it a try, it would be great to clear this code... (yet another one!). -
B1163-15 code - heated mirrors
Sorry to dig up an old thread I'm likewise getting B1163-15 (drivers door - US) and B1164-15 (passengers door - US). I'd like to take a look at the mirror and check the connection etc. as listed above. How do you remove the mirror, is it just a case of pulling on it? I'd prefer not to break... -
Blinding splash issue
I'm with you, dirt roads in Michigan provide plenty of *** holes! The only issue is the muddy water gets everywhere! Oh to be young again! -
2012 LR4 Reluctant to lower from off-road suspension mode
Here's the exhaust valve opening just after ignition on: The resulting gallery pressure (time axis is different because of the software being used) Driving down the road this then happened to the gallery pressure at the same time that the C1A13-64 triggered: I'm losing my mind on this one! -
2012 LR4 Reluctant to lower from off-road suspension mode
Just another piece of information... I notice that the fault often occurs first thing in the morning which has me thinking about cold weather (it's 28F/-2C right now). I read somewhere that just before the compressor is about to run the RLM ECU will vent the gallery pressure to reduce the... -
2012 LR4 Reluctant to lower from off-road suspension mode
Thanks for responding and yes I did just change to an OEM AMK compressor, I was really careful with all connections, treating them all to a clean, some wd40 and a blast with an air compressor! The key thing in my case is the randomness of this issue; it typically happens the most when starting... -
2012 LR4 Reluctant to lower from off-road suspension mode
A quick update on this; for those unlucky enough to have the C1A13-64 fault (Pressure does not decrease when venting the gallery") I still haven't found the solution but wanted to document what I've tried/learned so far to get rid of this problem... Certainly adding new O-rings to the three... -
Air suspension faults when cold out
How can you tell it's stuck? I realize it's a weird question but isn't it the smaller part inside the valve that actually get's actuated by the solenoid, so the cylinder that has the spring on it, this part: I think this gets pulled back when the solenoid is actuated and air passes through... -
2012 LR4 Reluctant to lower from off-road suspension mode
It's going to visit the ($)/dealership on Friday, is this something I could ask them to figure out? Thanks Folks. I though I'd share the review of the Unit I think I have (I also don't have an old solenoid...): -
2012 LR4 Reluctant to lower from off-road suspension mode
Thanks - in which case I have no idea... In the VIN, the C in your case stands for model year, so 2001 - would be 1 2005 - would be 5 2009 - would be 9 and so on up to 2010 where it switches to letters: 2010 - A 2011 - B 2012 - C It will go up to Z in 2036. So you have a 2012! The second... -
2012 LR4 Reluctant to lower from off-road suspension mode
It's a 2012 and looking on the Advanced Factors site they state this: "Discovery AMK Suspension Compressor. Use LR078650 if you already have converted to AMK (or Standard from VIN BA589828) Otherwise you will need the full kit LR072537. You can also fit the Arnott P-2645 AMK Compressor if you... -
2012 LR4 Reluctant to lower from off-road suspension mode
Thanks - I can do that. How do I know which one to buy, is it AMK originally in the vehicle or Hitachi? Once again coming from a place of learning! Do I have to re-program anything? -
2012 LR4 Reluctant to lower from off-road suspension mode
To answer my own question... I think this might be the unit (and not very good rankings) and others that mention the C1A13 error! https://www.amazon.com/Suspension-Compressor-Relay-2010-2014-LR061663/dp/B07N43V4F6/ref=cm_cr_arp_d_product_top?ie=UTF8&th=1 Grrr :-( -
2012 LR4 Reluctant to lower from off-road suspension mode
I'm not sure there are any leaks, it's definitely better on the front; the rear never appeared to have an issue and having serviced the 'o' rings it's effectively status quo. I did get the suspension fault again over the weekend so the next part to service is the middle compressor valve. I... -
2012 LR4 Reluctant to lower from off-road suspension mode
Back to the rear valve... WOW, what a pain in the a&* to remove... Per a YouTube video I lifted the back of the LR4 and removed the spare wheel, this was supposed to give me access to the two pipes (left and right suspension) and allow there removal... Not so fast however on a LR4; there's a... -
2012 LR4 Reluctant to lower from off-road suspension mode
Thank you for the tips, I'll start investigating the project, I tend to watch lots of YouTube videos and then go from there! I did change the front 'o rings and last night I did the rear ones, there's a great video on YouTube (starting with this one for general info - but on a RR Sport ) and...
