Hi there all,
The weekend i am going to try and solve my 5000rpm limiter issue i have, i have read up about the causes and i am hoping that it is just the Rotor arm out or the hall sender,
so am i right in saying i have to take the cambelt covers off, put the car at TDC, take green cap off gearbox to back sure the flywheel is correct then take the dizzy off and line the rotor arm up? or is there more to it than that? as i have read that TDC is done of Piston no1 on these engines? how do i tell if i have piston1 at TDC lol?
Many Thanks
-
I could do with some advice on this front...im clueless :(
-
Basically you want to put a long thin screwdriver down piston number one and turn the engine by hand until it reaches its highest point. The marks on the camshaft pulley and flywheel should then line up. Then take the distributor cap off and you will see a grooved mark on the distributor that the rotor arm must line up with. if it doesn't then slacken off the 13mm bolt and turn the distributor until it does then put it back together and give it a try.
-
It maybe the cambelt one notch out!
-
Just in the middle of doing this now, are there any marks on the cam pully that need to line up? Also is piston1 closet to airbox drivers side or gearbox side lol
-
Yes piston number one is closest to airbox. There should be a mark on the cam pulley and an arrow on the side of the cam cover that line up.
-
Also I can't see the 13mm nut to undo to adjust the dizzy? There's one holding a big black thing down under the dizzy lol
-
you need to hook up vagcom and see if its got any faults logged to do with the hall sender. it might just need a quick twist of the dizzy, you need to be watching the measuring blocks in vagcom to see when you're in the right spot. i think its measuring block 7
-
Okay then, I might just put it back together lol, does anyone have vagcom close to dudley?
-
There is a V shaped clamp with a 13mm bolt at the base of the distributors, slacken it and it should move. I set mine without using vagcom, just a code reader showing hall sensor fault although it will never be exact and you really need it set to the correct values. Why do you believe it out of tolerance anyway? has it had a recent cam belt?
-
i think deano is near you. or there is a place in cannock called midland vw, the guy who does the diagnostics there is pretty good :lipsrsealed: :grin:

5000rpm limit is a big clue. it could be something else but its the easiest thing to try first. depends what fault codes show up i guess!
-
Well I have just got it to tdc and the dizzy lines up but cam doesn't by about a tooth! I'm guessing that's what it is, but don't know where to risk timming it myself lol

Yeah but it won't knock itself out of time on its own though. More likely a fault with tha hall sensor or the wiring.

Flywheel mark lined up yeah?
-
I can't tell lol, is it meant to be noticible through that green hole on the gear box?
-

could be the dizzy itself, could be lots of things :laugh: strangely they do seem to go out of sync occasionally, just enough to trigger the code i've seen it on a few mk3s
-

Yeah there should be a visible mark on the flywheel, if you can't see it it may not be quite a tdc.
-
I can see like a big black bit in the hole, and looks like a tooth out, don't know whether to risk it tho lol
-
Right well I think I have the engine timing timed up! But still have a 5k limiter as I think I am trying to time the dizzy up to the wrong mark! Has anyone got a pic of what it looks like? Also my cars is using a lot more fuel, can really smell it to, could this be cause of the ignition timming out?
Thanks
-
Mine was having the same issue.
Plugged it into vagcom & got hall sender fault.
After a read up, I got vagcom to log the data, undid the 13mm dizzy bolt & turned it do the parameters were correct.
I'll try & find the link for instructions somewhere.
Took 10 mins & now revs all the way.
-
I am going to retime my engine tomo as it is out of time now anyway, as I timed it up wrong lol, then ill try to do the dizzy myself as I don't know anyone with vagcom near dudley lol
