3.0i ANS - Long hot starts

[DamFo 0]

Hello,

i have problems with my Audi A4 B6 3.0i ASN Quattro.

When is engine cold, car start absolutely without problems. After first turn engine running smoothly.

When is engine hot (operating temperature) and car stand more than 30 minuts and I want start, car dont wont start easily.
Engine is turning and car start circa after 4 seconds.

When i give full thortle car starts sooner.
Where can i find mistake? Throttle body? Adapation?

One of my underpressure pipe leaking (When car is running I can hear hissing) 

 

Thank you very much.

Hello,

diagnostic show only:

01073 - Clutch pressure system - but this error code can show because oil and sealing in defferentiel were changed

Other code: nothing.

Hello,

today I check engine measuring block 1 ...
Temperature on the CLOCK and measured you can seen on the screen below.

I have one finding:
when car is cold (after one night), outside temperature -7°C and I turn the key in the second position, needle on the temperature gauge little bit move, circa on the 50°C.

Tomorrow I order new temperature sensor and I will test it further.
