Thanks to Dek, got the diagnostics pluged in and faults were stored:
- vehicle speed sensor
- 81, pump relay
Is the pump relay the one hanging of the wheel arch right next to the battery?
Very strange cause tested relay and is ok same as that 60 amp fuse. When i send power to the relay straight of the battery i can hear pump working so i dont understand now.
cud now be pump pressure which means that operation maybe intermittent... if you hear the pump stop say after 1 minute of drivng, then I guess you would noirmally see the red light come on. Are you able to replace bulb in dash? I am not sure how involved that is.. but should be easy job for you
Replacing the bulb is easy enough - two screws for cluster surround, four holding it in, and then wiggle the dash out. Get new bulb, fit it in the right place and you're done.
15 minute job tops if you have the right bulb.
Got that light back up and running. Used brake ligh warning light bulb for now as i didn't have one.
Where can i get one, Halfords?
Going back to problem the AYC warning light pops up and goes out after turning ignition on.
As soon as i start driving warning light pops up and stays on untill i turn ignition off.
Noticed tha warning light pops up only when i go over certain speed, wont pop up if i drive very slowly.
Was the code 24 (via engine light), or the AYC light showing code 26?
Hhmmm engine management light wasn't on. DeK was checking DTCs and i just took a photo of his screen and im not familiar with evoscan but my picture says:
Reading MUTII DTCs for EcuID:E7A4
Diagnostic Codes:Vehicle speed sensor.
I guess it is via engine ECU but DeK will know exactly.
Don't use Evoscan for error code reading, it's not very good for that. Best way is to use the flashy dash method.

I've found some interesting piece of wiring going to the vehicle speed sensor on the back of the gearbox right next to the rear bottom engine mount.
There is another connector before actual sensor connector.
What is that black flat part with 4 wires (black, red, yellow, white) wired up to sensor wiring?
Is that original part or been added for some reason?
One of this connections was loose, yellow wire seen on the picture.
Resoldered every single connection thinking that yellow loose wire was the reason of the problem but unfortunately AYC warning light is back

Thanks Adam.
Hopefully that resolved the problem with vss fault which was via engine ECU. Disconnected battery after resoldering everything, so interesting what coedes are gonna come up now.
Tested everything today following troubleshooting for code no. 81: AYC relay system, and it looks like my AYC ECU is gone
Anybody has spare ECU to lend for a test? If everything works I'll be interested to buy that ECU.

I've got a "spare" ECU in my footwel that is currently in use but if you want to pop over to Berko and plug it into yours to see if that is the problem you are welcome.
