Hi, does anyone out there know how to override an engine mount fault code. The car is showing a P1586 error code (N144 N 145). I would like to disable this if possible.

 

​​​​​​Hello @Gin man ,
See post number 8 in the link below for the part numbers I posted, I am not sure if these cross over to the Bentley, but I'm 90% sure they will.

One thing to note, if your engine mounts are leaking a brown gooey fluid, you may want to change them out, or sooner or later you may have unwanted vibrations, you can replace your active engine mounts with the newer model non active mounts, but of course you would need to install both bypass resistors to fool the engine ECU'S.

It is odd that the newer GT's and FS's went with none active, as I have heard of complaints of vibrations 2012 - 2014 models when i was purchasing engines and transmissions, I will add that my 2005 GT with the 2011 Supersports engine and 2014 non active engine mounts, has no abnormal vibrations, just as smooth as my A8L W12 with active engine mounts.

Many thanks, I'll try and find the electrical plugs that go to the mounts, it would be nice to know the pin numbers into the ecu, that would make things easier, any idea's where I might find them?

 

@Gin man
What year and model ?

Johnny

 

It's a 2005 Continental GT.

 

@Gin man ,
Here is what I found.

Passenger side bank 1 for VIN from 20250, the red/slate of the B1 engine mount goes to the F7 10 amp fuse in the E-Box fuse box, the yellow/black from the mount goes to pin number 22 on the 81 pin plug of bank one's ECU.

Drivers side bank 2 engine mount has its red/purple going to the F8 10 amp fuse in the E-Box fuse box, with it's yellow/black going to the same pin # 22 on bank one's 81 pin plug ECU.

I would have thought that they would operate independently of each other, maybe the independent power from each fuse along with hard ground through mounting is how they work independently, and the 2 yellow black wires going to pin 22 are the sense wires.

Sorry for the long comment, I am just confused at the moment, as I would have thought the each mount's yellow/black wire would have gone the each ecu 1 and 2, or at least different pins on bank one's ECU, otherwise how does it decipher which is faulty...

So, I guess a resistor for each would go between fuse F7 to pin 22, and F8 to pin 22.

Many thanks Johnny, I'll have a look and try to fathom it out.

 

hi guys.

and could you solve the problem ?
I have also a fault code with flashing engine light.

but both engine mounts are defect at the same time ?

I bought the car like it is.

 

Hello @Cervezax ,
Your flashing check engine light has nothing to do with the engine mounts having a fault, the flashing light is because of serious misfires occurring, a flashing check engine light is a warning to stop the engine immediately, as your screenshot shows, the scanner is telling you to check for errors in engine control module number 2, as the vehicle has 2.

See pictures.

@Johnny Hotspur GT ,
do you know the value of the resistor? I have problems with identifying the colors of bars to get the coding.

 

Hi,
the problem started to be permanent on my side - i mean the error is coming back all the time.
I don;t see the engine is vibrating or smth. Just the error comes.

1. is it possible that despite the error the mounts are still functional ok?
2. how to get info which of the mounts (left/right) is with malfunction? I used non-vcds scanner and got only error 17944 code with no extra description.
3. adding the resistor will cause the mount will stop functioning or will still do the job but only the error will disappear?
4. what the value of the resistor should be?
4. how complicated the replacement of the mounts is?

Thanks for answer in advance!

 

Hey? Anyone could help?

 

​​​​​​Hello @sazam ,
Please double check the fault code, as 17944 is an engine camshaft sensor fault, but 17994 is for the engine mounts.

17994 is a short to plus, so, I would purchase the resistors that I spoke of back at the beginning of this thread, or figure out the resistance and make your own, this way, by plugging in the resistors you can test if it is a wiring fault, or either engine mount itself, another thing to look for, is the brown goop leaking out of either engine mount, the leaking fluid is a failed mount, if no leak, and the resistor shows all wiring good, and gets rid of the fault code, then it is your choice to either replace the mount/s or leave the resistors in place.

Just to note, the 2008 and up did away with the electronic engine mounts, the mounts look the same, just no electrical connection, as far as changing the mounts, doable from the bottom.

Hi @Johnny Hotspur GT ,
thank you so much for answer / suggestions.

You are right - I made typo - the right code is the 17994. Thought 17994 is one side, 17996 is the other.

I will check all as you suggest. Regarding valid resistance? I assume there are 2 active mounts, do I have the easy access to them from the bottom of the car?
What the resistance value is ok? I will probably have two different measures on one or the other (cause one may be ok other is bad), and no idea which will be the right one.
Are you able to check it on your car (if everything is ok on your mounts?)

Thanks a lot!
Cheers.
