+12V is missing on one of the uswitched power inputs to the ECU. Check fuses and relays.

Wait a minute... Why U-code, not P-code?

Why some FF data are so strange? Speed, temperatures, air pressure?
Terminal 30 at ECU looks ok (except weak battery)

OP, please post full autoscan.

Hello thanks for your replys, I have checked battery all good, cleaned fuses, replaced relay 100 in under bonnet fuse-box, and capacitor drain across battery terminals. if I start car and then clear fault with engine running fault does not reappear. but when the car is started it pings up code and puts EML light on full scan below

Searched my head + internet a bit.

I have some questions to OP:
- Is the topic title correct? Car is Q5 or Q3, maybe?
- What is engine code?
- Any recent work on car before Check Engine light and this DTC appeared? Repairs, chiptuning, any other kind of programming, drained battery, jump-starting etc.?
- Do You have WD?
- Have You checked power and ground at ECU connector T94? Pins 3, 5, 6 and 92 are terminal 30 (constant battery voltage), pins 1, 2, 4 are GND.

And a question to RT:
Is it possible that VCDS incorrectly displays this exact fault code as U140A? I have unconfirmed information that other scan tools are showing P0562 instead. And this EDC 17 internal fault table does not contain U140A at all.

Hello Thanks for reply, sorry it i a Q3 i just realized i made a typo error, no chip tuning and no recent work done and i do not think any jump start..engine code is CFFB and not checked any voltage at ECU car starts and runs fine just have EML light on
Also scanned it with TEXA and get same fault code what is WD??

If You want to get it repaired, You will need WD (point mouse at acronyms highlighted dark green and forum software will tell You what is it), DVOM, load light and some mechanics tools for the beginning. First check power supply at ECU connector pins according my previous post (pinout is correct, I decoded from autoscan data that it is CFFB in Q3, just asked to be completely sure). Do two measurements at each pin - voltage without load and voltage with load.
One more simple test - take good quality jump-start cable (only one lead) and make a temporary extra ground wire between battery negative and metal parts of engine. Clear code, start engine and see if code is back again.

Thanks for the info, I will try earth lead and let you know how that works out, yes i do have a DVOM and a WD, but the fault seems to happen in a nano second when cranking

Also You can try to swap the J317 "Terminal 30 Supply Relay" with another one. There should be some more with the same partnumber in the engine compartment fuse/relay box. Oxidized and/or burnt contacts of this relay may cause that fault code stored at time of start, too.
For the Passat B6 exists a TPI for that fault code - damaged wiring in engine compartment. (Red/green wire supplying power to ECU pins mentioned in previous post.)

I have changed out the relay in the engine fuse box,which controls the engine management it was showing number 100 on the top of it, exchanged it with another one, but still no difference,
