Igniton Timing for 2.0L 2E engine??????

[Special Air Service]

I can't find any solid info for this anywhere, Bentley has info for other 2.0L engines but doesn't seen to apply for the 2E.

Can anyone help out?

Not having any major issues just trying to ensure she's running the best she can after replacing a few other components.

Pretty sure you can't adjust it. The dissy is pegged IIRC and the ECU looks at the crank position.

No on mine it isn't pegged, once you loosen clamp the dissy can be rotated as per normal when adjusting timing. And the timing moves retard / advance as per normal.

Everything I've seen about 2.0L says its pegged but I think that's all US related engine info.

Hi SAS,
Gavin is right. When you loosen the clamp and rotate the distributor, the revs will rise or fall then the ECU will readjust to the factory parameters.

No worries.....so is there any basic tuning adjustments that can be made, or is it all controlled by the ECU?

Set it up as if you were setting up a MK2 Digi 1.8
You can play with timing (dizzy) and idle (there's a routine to be carried out).....and that's it.

Don't be too concerned with CO.
All of the above info relies on your 2E being in an early MK3 and that it's running on Digifant

Thanks, I will have a play & see how I go.

Couldn't find any idle adjustment screw on my throttle body by just looking at it in the engine bay, so took it right off to have a good look & to give it a decent clean........and no there is no adjusting screw. And only what I think is a throttle position sensor. On the digifant on my caravelle there is adjustments on the throttle switch for idle position & wide open throttle (if memory serves correct). None on this one.







I also cannot get it to show only 6 degrees advance when I rev it to 2500rpm. It just advances like a normal car then returns to 6degrees at idle speed.

Must be doing something wrong.......is there something I have to do to reset the ECU after disconnecting the coolant temp sensor etc?

Everything I read talks about disconnecting the "Blue coolant temp sensor" but mine is not blue, or am I looking at the wrong one?

[mattross]

all done in the computer, about the only thing you can do is re align the dizzy to the marks.

[mattross]

careful with the intake, generally if you play with anything on the throttle electrically, the ECU will go into "limp home" mode and you'll need to VAGCOM it to clear the code. Is that engine an AGG, i'll check my bentley for you

[ryana89]

Righto,

IIRC I played with this screw to adjust the idle,

However, before touching idle the timing should be set.
I'll be honest I did this by ear until eventually it was running at the correct 6 degrees before TDC.

From what I understand, the sensor (the black one ontop of the coolant flange) is what a MK2 owner would call blue temp sensor.
Difference is on MK3 combine 2 sensors into one (ECU coolant temp and Gauge coolant temp)

Have you touched the timing yet? It usually doesn't need to be touched.

Is that engine an AGG

Be nice if it was, but see the Idle control valve ontop of the valve cover and the 'barn door style' Air flow metre?
Makes it a 2E running on Digifant.

[ryana89]

Also, when setting up idle, don't forget to unplug this hose and block the intake side.


(You may have already been doing this, just checking)

[Special Air Service]

There's no adjusting screw on the throttle body at all, the location that you've cicled is just a blank port in the casting. nothing there at all.

And no I forgot to block that hose off (always do that on my caravelle as well).

will have to get back to this in a little while as I'm now in the middle of replacing the clutch.

what a prick of a job that is.

wire needs disconnecting

There should be a wire to disconnect to set the timing like the T3 has I've not seen a 2e engine or read about them but VW always make things similar to other models of the same era. Brendon on the T3 its the yellow wire that is disconnected to set the timing it cuts out the the computer during timingso its like a normal engine to time

Whoa! Lots of random info jiggling around in here...

2E engine:
> Idle speed is controlled via the ECU, using the idle control valve which is that horizontal cylinder thing on the rocker cover. You CANNOT change the idle speed manually (why would you need to?). Any vacuum or air leaks will cause issues - eliminate all of these sorts of problems before you go trying to adjust things that the ECU should be controlling.
> Timing - set the timing to 6-8 BTDC with warm engine. All further adjustments are made by the ECU. The distributor uses a hall effect sensor as the pickup for the electronic ignition control, so you only need to have it about right.
> Knock sensor should be fitted to the front of the block. These can be damaged or break over time, they aren't too expensive. You wont get full performance without a working knock sensor.
> Coolant temperature sensor function is critical to the correct mixture control for the engine. These are cheap - if your not sure about it, fit a new one.
> Spark plug gaps - shouldn't be too large.

The 2E will run perfectly and just about forever if all of the above things are covered.
