Z20net turbo keeps loosing the turbo switch on/off and it's running as normal

[tomo41]

As above it's really annoying

sound like limp mode have u read the codes could be ya maf sensor or a boost leak

[Caveman_nige]

Probably the boost solenoid, codes will tell you

[mikey c]

I posted same thing yesterday but got no responses. been told its knock sensor, part of ignition module. just ordered new one so will let you know.

did you read off the fault codes?

[tomo41]

Mine only seems to do it when loading up in 6th gear can't read codes as they come up on the spanner light and any got a code reader for that

[micks edition 100]

mine has started to do the same but there is now spanner light coming up sometimes you put your foot down and you get like a juddering and then it clears its self .then like you say turn it on and off again and its fine and pulls like a train

Boost solenoid or waste gate actuator diaphram are the usual suspects on our engines.

[beat275]

Where do you get the waste gate actuator diaphragm from? And where is the knock detector

I think i will do the boost valves first i replaced them about 2 years ago but i understand they go when you have had your car remapped
