I gather that, what I meant is what’s wrong with a bit of smoke?! And it’s not excessive, I think a bit of black smoke is only to be expected until the turbo kicks in properly

You said earlier it shouldn’t do it at all I thought you meant it was going to damage something or cause problems.

Sorry I missed the last bit. Yes a little is expected, I don’t think I’ve got more than a little
Just the once and brandbnew injectors. Mine might be due to fuel pump pressure as it's quite noisy; does mean i can hear the glow plugs come on and off with the current draw changing the pitch of it slightly

I’m just going to run mine and see what happens. If I let it idle for 30 secs before driving away it’s fine, maybe it’ll get worse

You should do that for at least 15 seconds anyway every time no matter what for the sake of your engine and turbocharger

I should think 9 times out 10 I do anyway, but only because I'm still trying to fit myself in!

mine throws some slight black smoke on take off does this mean mine is chipped ?
mine is an auto i also get some slight puff of black smoke on take off and when the transmission changes gear depending on load and heat of the day
bearing in mind my injectors are not brand new either allong with with new bump heights

not to sure if the engine is already up to operation temp in your vid so i cant comment
cold engine i normally tend to watch my boost gauge and stay in low boost for a few minutes or as long as i can untill the engine is up to operating temps
idle shut down is also very important for the turbo we need to bring down the turbo back to idle temps... some install turbo timers i have installed a accumulator tank basically near the same as a turbo saviour but without the filter.... the reason i installed this as i didnt want to idle my engine to long when i get home from a night shift .... also i always try to stay in low boost when iam near my destination (driving style ) some times this cant be acheived just been on full boost only to pull into the 7 11

How does a turbo timer work does it stop you from switching off the engine for a set amount of time?
Also does anyone know the part number for the glow plug relay on td5? Can’t seem to find it anywhere!

correct some advanced turbo timers can also self adjust .depending how deep you want to go..... but a basic turbo timer can be set from 1 to 5 minutes depending on type of system
many people will argue the fact that the stock td5 does not need a timer but they forget the the nature of a turbo and how it works
glow plugs what glow plugs? i have never used mine so i cant comment mine starts with the flick on the starter motor

Clutching at straws really, it’s probably nothing to do with glowplugs as mine also starts on the button just runs like a bag of s**t. If I let it idle for a while it seems ok, but otherwise it misses and produces white smoke. Strange really.

Thought about injectors but it’s only at startup. Even put a different set of injectors in with no difference

even if you dont care about the glow plug warning lamp when you start the engine the glow plugs have a "post-heat operation" after the engine was started untill the ECT input gets to 20*C, if it's cold this can take few minutes and beside other things is reducing the carbon build up so no matter how it starts it's a good for the engine to have them all in good working order
ENGINE MANAGEMENT SYSTEM - TD5 ; DESCRIPTION AND OPERATION 18-1-31
.......
- The glow plugs are a vital part of the engine starting strategy.
- The purpose of the glow plugs is:
l Assist cold engine start.
l Reduce exhaust emissions at low engine load/speed. - .......
- Pre-heat is the length of time the glow plugs operate prior to engine cranking. The ECM controls the pre-heat time of the glow plugs based on battery voltage and coolant temperature information via the glow plug relay.
- Post-heat is the length of time the glow plugs operate after the engine starts. The ECM controls the post-heat time based on ECT information. If the ECT fails the ECM will operate pre/post-heat time strategies with default values from its memory.
