[Vwdiesel] Injection pump timing?

Heh! I have several smoking-when-cold diesels and I figure the problem is retarded timing. Dad said one day, he didn't know which smoked worse; the stove (starting up) or the Tractor!! (a SAME, pronounced sah-may)
The passat is really bad but clears up when it warms up. Temp sensors all show relatively correct (didn't check if EXACT). If I go to "basic settings" when I get to 004, the idle smooths out, speeds up, sounds much better and the timing goes from barely BTDC to about 8 degrees BTDC. If I go to adaptation, all chanels come up as not available! Ugh. Beginning to hate the electronic part of the TDI.
Replaced the top rad hose-to-head, flange yesterday. No cracks but it'd been leaking. Appeared to just be the o-ring but replaced the whole thing BEFORE it cracked.

Here is a modification I recommend for the AAZ pump. There is a timing
etard solenoid on the front of the pump. Wire it to be powered full time
ith the fuel shut off switch. Then re-time it as you would a 1.6TD. I
eem to recall .95 working well. That solenoid retards fuel timing below
000 rpm for emissions. It also reduces performance.
