not firing on all cylinders

[141]

My 106 Gti outer cylinders are not firing the inner 2 are. I have replaced the spark plugs and the ignition coil (64 on link). After replacing the ignition coil there was a slight improvement in power. Any ideas what the problem is?

Cheers

How do you mean not firing? no spark?

If not i'd be looking at a compression test next

I do not know if it is sparking.. I just know they ain't working. The garage said it could be a wiring fault or oil pressure. I have tested the wiring an it is fine. How can I check that it is an oil pressure fault or something else?

you need to take each spark plug out

turn the engine over and see if plug sparks


the spark plug will need to touch bare metal

The spark plugs have no leads attached. They have an ignition block which I replaced. To remove one spark plug you need to remove them all. It is at the bottom of the link. Cheers

You have to consider it may be the ECU. It works in pairs just as you've suggested.

I looked on the internet and it said the ECU needs the software rebooted. Trip to garage I suspect. Cheers

I have disconnected the battery. If left off long enough will this reset the ECU? I have found the software http://kms.vankronenburg.nl/.. Which software on the website should I download to reset the ECU? Cheers
