cts Coolant Temp Sensor

Hmmm still throwing same fault definatley the correct CTS?

cleared the faults after install?

if so possible wiring fault?

[bikemach]

yeah am starting to think it could be a faulty connector, noticed sometimes the temp needle dont seem to move after my drive to work (about 5 mile),
starting to annoy me now lol,
is there more than one semsor?
and where are they located please,

Daft but thermostat?

[optispart]

good point thermostats are known on 1.8t ill take a pic of cts mate just the one im sure

[bikemach]

thanks, had a look at the new cts yesterday, seens the plug was not snapped into place propperly,
wd and snaped the tab down with a small scred driver, will have to wait a couple of days to see if my light comes back on,
but yeat could change the thermostat i suppose, never thought about that,
car is a standard 2.0 8 gti,
looking for a 1.8t if i can get one, the 2.0 8v gti dont feel like it should be a gti !!
will update in a couple of days or when and if light comes back on,
also i have a crash data removal tool and airbad fault code remover if anyone close to me needs to use one.

where are you bud i could just do with that atm lol
