A5 Cab 2.0 TFSI wont start ! Help !

[Cabbyfan]

Hi,
My A5 Cab 2.0 TFSI wont start !
Key in the slot - everything lights up as it should - press it in to start (with foot on clutch) and the dash goes off but nothing happens.
Full VCDS scan shows nothing obvious

What I do have is under the engine module 01 and readiness is this :-

Readiness Status: 1110 0101
Exhaust Gas Recirculation: Failed or Incomplete
Oxygen Sensor Heating: Failed or Incomplete
Oxygen Sensor(s): Failed or Incomplete
Air Conditioning: Passed
Secondary Air Injection: Passed
Evaporative Emissions: Failed or Incomplete
Catalyst Heating: Passed
Catalytic Converter(s): Failed or Incomplete

I swapped out the 1A relay in the engine compartment, no change.

Help !

If you scan the clutch switch does it change state when you press it?

Hi, thanks for the reply. I can't find a control module that shows clutch switch status on VCDS.... measuring blocks on Engine 01 are greyed out too.

Hi, so I found out where one of the clutch values is - not sure if its the clutch pedal itself or the one on the servo...

IDE00355-ENG57549 Cruise Control System (CCS): status-Bits 0-7 00101000
IDE00356-ENG57549 Cruise Control System (CCS): switch position-Bits 0-7 10000001

When I press the clutch or the brake pedal one of the bits changes value on ENG57549
101001 and 101100 (rest state is 101000)

ENG57549 didn't change at all.

Been trying to fix this since Sunday and I am thinking its time to get it taken to an indy to fix.

Brand new battery fitted now, still the same issue.

Have the similar problem and fix it with clutch change. I need to really hard press clutch pedal if want to turn on car.

Hi, Thanks for the suggestion.

Doesn't matter how hard I press it, still doesn't start. VCDS shows me the clutch switch changes state so for now I'm thinking it's not that.

What is odd is Terminal 15 goes off when I press start. Going to check access control module tomorrow.
