Title: On my way to pickup the dreaded ecu Relay.... RESOLVED.. thanks for the help
Post by: MrDan on 18 December 2009, 11:17
When I find a lift down there.. no car is killing me!!

The beast is getting fuel and a spark but just not starting, Only codes on Vag-com are hall sensor that has been there for about 12 months (5k limit problem)

I cant take any more walking around in the cold!!! I hope this fixes it

Have you checked the cam timing reference 5k limit problem.

If your limited to 5000 revs then the ECU relay wont fix it!

Its a timing issue and probably that hall sender as well.

But it was working fine, just wouldnt rev past 5k,

does the belt slip a tooth?

It should not but if the tensioner was to come loose it could happen.

It might do.


No it wont slip a tooth! If it did the tensioner would be loose and that would be disatrous!
It maybe one tooth out or as seen recently 180 degrees out! But that would be because the numpty that did it fitted the belt wrong!

Just for info, I have seen cam belts jump a tooth.

hi guys, thanks for you input on this.

changed the ECU relay anyway but no dice, due to being hungover and it being very cold im going to look at the timing tmorrow,

would my best bet to do the following,

- remove cambelt cover and move engine to TDC

then start with the dizzy? i think I understand the instructions...

Hall sensor... replace your distributor

okie dokie... Car mechanics in the snow!!

Lined up the OT marks to get the engine to TDC and the rotor arm seems to be about 15 degrees out to the right of the mark.

the entire dizzy inside looks rotten (some oxidisation on the metal parts)I  removed the bolt at the bottom to try to adjust the timing to see if it would make a difference but the enitre thing will not budge, Didnt want to put too much force on it and cause any damage, but I take it the whole unit has to come out and be moved round one tooth?

It does appear to be jammed solid to the block!

Any advice much appreciated!

yep thats a fixed one, you'll have to loosen the belt and move the intermediate shaft round to line rotor up with that notch. looks like the last guy who did your timing belt did it wrong!

you can just about pop the shaft round a tooth at a time if you remove the front nut that holds the belt cover on, but it can be a struggle.

also well worth taking out the flywheel inspection bung on top of the gearbox, use the mark on the fly wheel instead.  It needs to be loosened, has a large hex in the middle. I've not found anything large enough yet, so I tap em rounds with a hammer & drift.  Reason I say this, is because on the last MK3 2.0 8v I timed up the crank pulley mark was near 45 degrees off!

Thanks for that info rubjonny!

Last retarded question from me... which shaft is the intermediate shaft?

Is that the second pulley down opposite the tensioner?

>Is that the second pulley down opposite the tensioner?
yes

what are you lineing the dizzy up to?

>also well worth taking out the flywheel inspection bung on top of the gearbox
+1.  Don't bother with the crank markers - not accurate enough

thanks for all you help with this, I got rather naffed off with it and called a mobile mechanic out for a second oppinion to mine!

He thinks its the coil pack, As the spark is not strong enough but is regular.

I did change this on the 2nd September so its managed to eat one in 3 months

Anyway, £30 lighter for his time and Iv ordered the part... lets see if it was that simple!!

It was the coil pack! for so anyone reading this in future, Even if your getting a spark it may not be strong enough. My coil pack was only 3 months old.

beware of cheap immitations!!!

Glad you got it sorted.

But did you sort the timing?
Title: Re: On my way to pickup the dreaded ecu Relay.... RESOLVED.. thanks for the help
Post by: MrDan on 23 December 2009, 11:24
I got an mechanic to check it and was told it was fine.

Saying that I started the car this morning and it cut out, battery flat now.

hope its just the cold!!

From what you had said earlier timing was way out! But hey if its working fine then good luck!
