What's Normal?

huh? is that to do with emissions?

Yep, I think alot of the emissions laws state that the car has to be producing less than X amount of emissions after ~X seconds. Its the main reason most cars run rich on startup (to heat up the cat and get it working) and why they will rev higher idling from a cold start. I'd guess car can't heat the cat up enough sitting idling and do whatever else it does to get emissions ready.

I'll always let my car sit for 30seconds ~ minute before driving - To take the edge off the cold and to make sure oil has been pumped up to the top of the engine.

(All Audi manuals say the same thing)

It was the same a long time before cats and emission regulations. VW says to warm the car up quicker. Increased revs are to stop stalling.

What's normal?

Hi again,
I need an idea as to where to look for the coolant temp sensor on my 1.6L, being a new owner (2 days) not familiar with the layout yet.

Thanks

Pics of the page?

Here's the pic. I'm just old school thinking that to warm up a car in the morning its best to just let it idle ...which is why I first thought it was a misprint.

I believe from having read this topic being discussed in another forum that the old adage of letting the car warm up for five minutes before moving doesn't apply anymore. The car's are advanced enough so that starting them up and moving off after 10 - 30 seconds is fine even beneficial.

Of course that doesn't mean go revving the crap out of it.

back to the question

Getting back to the original post, I managed to locate the teperature gauge sensor, pulled it out, cleaned the terminals on the plug and refitted....problem fixed.

Well done, great to hear everything is working fine now...
