strange metallic chi chi chi chi rattle on acceleration

did tell you what it was

did tell you what it was

pinking ? we'll see, not many people know about setting them up so getting somebody to do it is rocking horse crap, guess ill just go round in circles till i have replaced ever part under the bonnet LOL

hand on so vw did what? and they knew the problem? they got f**king dicks working in there or what? if the prob is still there, you shouldnt have paid, as there was a prob with a rattle and its still there. did you ask them to change the gaskets? mine is the manifold gasket! btw how much did it cost?

[danny_p]

it has a broken sensor. allready said what there likely to be

[marky-gee]

Are all golf knock sensors the same(ie, will a vr6 one fit a 8v?, or are they tuned to the engine?)as the are a few golfs domwn the scrappys near me and I could "inherit" some.

[danny_p]

there quite interchangeable the differance between ones on diffrent engines is the length of the lead usally. 

the bolt must be done to 20nm when refited,  the torque is critical as it loads the sensor wrong torque and it senses wrong

[sharki786]

sorry to high jack, but say the knock sensor is old but theres abit of knocking will there be alot of diffrence if it was replaced or will there be a little diffrence?

[danny_p]

if the knock sensor is fubar it'll not tell the ecu about knock so when knock occurs the ecu won't do anything about it, if the ecu knows the engine is knocking it'll retard ignition to prevent the knock ( to  a point ) 

most enignes will knock under heavy accseloration on 95 octane fuel when hot if the knock sensors are disconnected.  the other possible cause is the airflow meter under reading and running the engine lean under load normaly the knock sensors will pick up he knock and retard the ignition to compensate.
knock sensors ae first port of call

Well it's still sounds like a load of pish,

New knock sensor, new Exhaust manifold gasket, new inlet gasket, new injector seals, new downpipe gasket, decated with new gasket, New blue temp sensor.......What else could it be f**k me ??

[danny_p]

we may need a better description of the noise then. 

dose tempriture make any diffearnce ?
