I have been looking around the forums and I'm trying to find technical info on the vvc. timing, sensors etc. Not getting much luck. Can any one recomend places to reserch vvc timing settings, common faults when the timing is out?

this car is driving me and my mechanic mad!

I have even put it into a dealer and they came back with (after taking £80 off me)

put it on test book, and you have ..
ambient air temp sensor fault
oil temp sensor fault
coolent sensor fault
srs capacitor fault
internal mems voltage fault

"we cant reset any of them mmmm could be electrical"

"oh by the way the fault you brought it in for ...to look at that cause its a vvc we would have to check the timing before we did anything about £300 just to look."

I have posted the full tale of woe on the ask the gurus section
any help greatfully accepted.

Most of that is pretty easy stuff and nowt to worry about with the exception of

SRS Cap fault and the MEMS voltage fault.

The others are just swapping sensors, pretty cheap and easy to do.

However the point on timing a VVC is valid and unfortunately they can be a bit of a pain. Some procedures that might have to be done can involve special tools.

However looking at your post in ask the gurus.

The airbag control units are different between the single and twin airbags.

Your misfire under load could be as simple as plugs, leads, coils or the crank sensor.

Check the earth connection of the engine. (temporarilly) Add another just to make sure.

There's a nice website showing all the inputs and outputs on a VVC and which signals/voltages to expect. I've got the URL at home, I'll post it later on.

The guy has something Caterham-like and it is VVC powered.

As said above, check the earth.

Also check the MEMS wiring harness and ECU plugs.

Doubt all those sensors are shot and sounds like another fault.

Worst case, duff ECU.

Are you sure your car isn't hit by a lightning ?
