2006 4.2tdi warm up time

[MattyV8]

Hi All,

Quick question - just wondering how long this engine should take to get to 90c as I have a 11 mile drive to work and it gets to just under 90c in that time. Does this seem right? I know its a big engine but apparently the 4.2 fsi takes 5-6 miles which is half the time.

Wondering whether the thermostat may be at fault.

Cheers!

I don't know if the D3 is the same, but the temperature gauge on a D2 is at best an "indication".

Been a while since I had a D3, but all things being equal sounds about right.

Diesel engines are more thermally efficient than petrol, so much so that they often need an auxiliary heater so you don't have to sit in a cold car for ages in the winter!

On the D3, that is diesel fueled and sits on the coolant circuit. In the summer this won't activate, so 12 miles to get "warm" doesn't seem unusual?

Thanks for that, it makes sense. I had a 3.0l x5 previously so guess I was used to that. Will be interesting to see what difference winter makes.

I think mine is about the same, I travel 20 miles some dual then A roads, today was a bit cold first thing 06.30, I noticed the temp inside took longer to warm up.

On the roads I travel, I barely get over 40 for the first 8 miles then 60 for the last 2-3.

Thanks for the input.

Love this car!
