Hi Folks,
Replaced bad Injector - Tech 2 identified No: 4 (both Click and Balance Check). Was 3.5 hours a good effort ?
Had one Grade 42 Spare as I got 2 from Trooper Dan 2 years ago.   (Sorry Dan - still never got round to sending Photos of Drivers Front seat - but wire going deeper in the butt is getting me motivated).

Currently Physically the Injectors are;

Cyl 1 - 44
Cyl 2 - 42
Cyl 3 - 44
Cyl 4 - 42

All coded B1 now (were Coded by Dealer B2 ?)

A "Nonet" of Questions,

1. As this was last coded by a "Decent" Dealer - did they deliberately code B2 as "leaner" to help emissions ?
2. Watching Live Data Display - See Desired Oil Rail Pressure on Idle 4Mpa - Actual varies 3.9 to 4.4 - is that Ok ?
("Zeroed" it when Rail was drained before Restart)
3. Idle Speed, a bit puzzled here - Desired seems to vary from 720 to 850 - Actual follows suit within 10 rpm - why does "Desired" alter. Can you set it ?
4. The Tech 2 has some thin blue horizontal lines (3 now) "developing" on the LCD, is it a sign it is failing completely, or is it a common thing you live with ?

5. Appears to be running Fine now, starts approx. in 3 Sec's (One Potato - 2 Potato - 3 Potato - Fires)  is there anything else to think about / Check ?
6. The TPS flashes the MIL occasionally - and stores a fault - usually "Not Present" when checking the DTC codes - can it be "disabled" - I think somebody suggested removing
the butterfly plate in the Throttle body, but will it simply give the same error without it ?
7. See some tests and settings related to EGR, as I have simply cut the threaded bit off a nut to make it smooth - and stuck it in the pipe, can these be ignored ?
8. There are 2 options in the Tech 2 for Programming Injectors - one refers to Euro III, but it seems to ignore changes made in that Screen, the "Standard" option
works fine - and the Changes are reflected in the Read/Store option. Using the Euro III option - nothing Changes.
9. Finally see some options regarding testing opening/closing Exhaust Flaps One and 2, assume this is the "Cold Start" stuff
and should be left well alone ?

Sorry for the Exam like list.

Thanks in advance.

Ciaran.

Too Much at once ?
Better post singly ?
