U140600 ошибка audi

Anyone know what this is?

Fault code U140600

Status: Intermittent

Static current too high

I once cleared this fault and it has returned.

^^ hmm……. U140600 is a generalized error message — its caused because the control module monitors the electrical current flowing in some wires. When the amperes in these wires exceed a threshold value, the DTC is triggered.

It obviously can be caused by a genuine faulty component in the car — but more frequently it is caused because an additional piece of equipment has been added to the car’s wiring and the supplying power for the new device has been taken from a monitored fuse position.

Has this happened — perhaps a new dashcam, or powered USB port, or another electrical device?

Hi all,

Same error for me also. I do mention that i connected a dash cam via a smart box (mivue smart box) that offers power to it for parking mode. I left the device to just power the dash cam on contact (connected via a fuse thst was for the back whiper). After reading what you said i guess that this is the reason for the error. My question is what to do in order not to have the error and also the dash cam to work? Any adivce? Is it terrible if i don’t take action for this error?

Could this also occur when you have a charger connected at the same time? I always attach a charger (Smart/maintenance type max 4amp) when doing scans etc. OR if I have not used the vehicle for a while or intend not to use it for a few days.

Last 2 times this error came up when doing scans. 

I also have a dash cam BUT I switch it off when the car is in my locked garage as it has a parking mode and they can drain the battery. It is connected to one circuit for when the vehicle ignition is on/running and switches to another circuit for parking mode.

Hi , i mounted exit door light and i can not solve the same fault codes . What i have to do please?

Folks, I’ve also got this issue.

I recently bought (2 months ago) a 2019 A8L 50 TDI (U.K.) and I am seeing this U140600 fairly frequently. I do have a dash can wired in, but I fully disconnected it and still get the DTC. It occurs when nothing external is connected to the car — no phone cables or anything (both with ignition on but not running and also when engine is running).

I’m also getting the DTC for the windshield sensor heater occasionally as well — could it be related?

Any troubleshooting steps would be helpful.

It’s difficult to say whether the windshield heater sensor is implicated in your U140600 problem — it’s possible (I guess). Chasing this type of problem is finicky — but it’s not difficult- however it does involve a degree of effort.  It really does depend on how serious you are about diagnosing the cause of this error

So, if you want to proceed, let me introduce the term «Parasitic Current Draw». Not sure if you are familiar with the term — but it’s used to define the (often small) electrical current that can «leak» in a wire when the car is meant to be in the sleep state.

The measurement of parasitic -current in a wire is best done with what’s called a «clamp-meter» which looks something like this (hence the name):

But I assume that you don’t have access to this (special) device. It is possible to use a common multi-meter to measure parasitic-current. This method measures the (small) voltage-drop across the car-fuse. If you think about Ohm’s law — if a wire has a leakage current, there will be a small voltage drop across the supplying fuse because the fuse-element has a a small electrical resistance. Of course, if there is NO leakage current (as should happen when the car sleeps), there will be NO volt-drop across the fuse!

Hence the volt-drop measurement technique becomes a surrogate for detecting parasitic- current. However, to understand what the measured volt-drop means, this method requires a decoding table that translates milli-volts into electrical current. This information is provided by fuse manufacturers and it can be downloaded from the internet

The finicky part of chasing parasitic current draw is that it can require that you test ALL the fuses — but again, this ain’t difficult (it’s just finicky).

So, if you want to chase parasitic-current on this car — look at the video below
