quattro Digest, Vol 4, Issue 57

[Larry C. Leung]

At least on 10VT, this sounds like the classic leaky injector 
syndrome. They leak fuel out over the time between cold
starts and it takes awhile for full pressure to build up after 
starting and the fuel pump has time to catch up. 
How old are your injectors? On 10VT's its usually time
to replace after about 60K miles (about 95k km).
