5000rpm max!!!!!!!

Timing may well be the issue here , whether or not you can do it yourself definatly seems to be an issue !!!

Y has no one suggested to this poor fellow to get the problem codes read from his ECU ? If as has been suggested that the engine is running in 'safe' mode surely the ECU fault codes will indicate this  ?

Just a few things again to add.
The ECU does not continually adjust ignition timing at idle, and this is when a timing gun is used.
The ECU will adjust the ignition timing according to engine speed and load.
If you guys are convinced that timing is a problem, which i am still very much doubtful, then check the static timing, it is easy enough to do.
Something i think that is worth checking is the knock sensors, if one is loose then the ECU will retard the timing which could cause a problem.

adyh - that is a very good point

But just another point to note is that if there is a problem with timing it may not post a fault that can be read as this.

It will almost definitely post a fault on the hall effect sensor as mentioned, but once the timing is set, it should correct this - if it doesn't, then it will need a hall sender.

VR6 - my point here is not HOW you set the ignition timing, but that it COULD be the fault that is causing his problems! and i was merely suggesting that this would be the first thing to try as it is the easiest and cheapest to rectify! Just passing on some well earned knowledge and didn't really want to argue about it. I'm just trying to help the guy!

Let me know how you go anyway!

ive got the same problem cant rev over 5000 rpm 97 R reg 2.0 gti "starfishcracker" is right i put mine on a diagnostic machine today (doesnt have to be main dealer) and it come up with "hall sensor signal outside tolerances error occurs intermittant" it is down to the distributor im not sure if you definatly have to have it set up by vw but ive ordered a new distributor ?95 + vat and im going to try that hopefully it should work
