Cold start valve on a 'G' reg? You sure? That must have hung around a bit before being registered.

[Rizy247]

Not entirely sure what you mean by registered?

Looking for these two sensors am I right in saying one is cold start and one is temp ?

Blue / brown

The last 320i built with a cold start valve was made several years before G reg plates were issued, so you're car would have had to sat somewhere unsold for some time.
The two items shown are the engine coolant temperature sensors. The brown one is for the temp. gauge, and is most unlikely to be faulty. The blue one is for the engine ECU, and while, it does tell the ECU to enrich the fuel mixture while the engine warms up from cold, its duties are more than that, and I've never heard it refered to as a cold start valve.
The blue one does occasionally become faulty, but a much more common problem affecting it is moisture getting into the back of a plug and socket that the signal from them passes through, which can be found under the inlet manifold. It's not the plug and socket themselves that's the problem, but the wires to the bottom part, which corrode internally.
If you do need to replace the blue sensor, use only a genuine one.

Looking at the photo I see the large round facelift post '88 diagnostic socket rather than the smaller flat sided pre-facelift one and it looks like the radiator breather pipe heads off to the left, also post face-lift. Radiator is later one too. so a 1988/89.
