TDI(s): '09 Jetta
Default 2009 Jetta TDI and remote start

Anyone know what remote start is compatible with the '09 Jetta TDI? Is a remote start something that is okay to install in one of these as I heard that a remote start won't warm up a diesel engine. Is that true?

TIA

This will really depends on where you live. I think in general, Remote starting a TDI is not a great idea, however if you live in a warmer climate like Florida, you may be able to get away with it.

In cooler areas, when the tempature is cold, the glow plugs will need a few seconds to warm up before trying to start the car, thus if you tried it via remote start, it will be unsuccessful.

Diesel cars do not warm up during idling... Plus, idling when cold for diesels does not do anything good for the engine.

As long as it's not cold outside, they will warm up by idling... just veeeeeeerrrrrrry slowly.

I might go idle mine up from cold just to see how long it would take in 60'F weather.

Boredom solved.

Well, I live in Chicago. If it is 5 degrees outside and I leave it outside overnight, when I get in the car what is the proper procedure? If it doesn't warm up while idling then do I just start the engine and drive away without letting it idle for a few minutes? If so, I should keep the RPM's down until the engine is warmed up?

Yes, just get in and drive, no sitting around... I would have to say (im not a guru, just read alot) that you should not go WOT when cold though...

Best option will be a frostheater when it is available for the '09 and just leave it plugged in on a timer to come on 2-3 hours before you are ready to get moving in the morning.

Cool thanks. Got a website for that frostheater thing? I've never heard of one of those.

It took about 15 minutes of idling to get up to 190* in 60'F weather.

A frostheater would definitely be a better way to go.

Read the post. It does, it just takes about 15 minutes.

what about in cold winter wheather, say -15 degrees? if it took you 15 minutes to reach warm temp in 60'F it appears that it will take 30 minutes of idle to reach a warm enough engine where the heater actually blows out hot air.

THAT is the point.

When it is really cold outside the cars will NOT warm up no matter how long you let them idle.

There is just not enough waste heat produced.

Search is your friend and so are the stickies spread all over the forums.

Diesels are much more thermally efficient than gasoline engines. They don't produce enough waste heat (wasted energy!) in idling to effectively warm the car up. Diesel engines warm up under load, IE driving. Seat heaters are a wonderful thing for just that reason. Additionally, several folks have mentioned that the 2009's blow hot air well before the engine is warm, which means it has supplemental heat of some kind to warm the cabin air. So, no need to let the car idle for 15 minutes and risk engine damage.

09 TDI have an electric heater, everytime I turn the fan on when it's cold I can hear electric relay clicking sound and warm air starts to blow from vents.
and when comes to cold starts, just start the engine, give it few seconds for the oil to get where it should be and START DRIVING. Keep your rpm's around 2000 and shift around 2500. when engine warms up (engine temp needle above second white mark), drive normaly.
