2006 4.2tdi warm up time
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". :rolleyes:
|
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? |

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! |
Sounds like your Aux heater aint working, which isn't uncommon.
D3 4.2 TDi should heat up reasonably quickly. D4 4.2 Tdi they did away with the engine heater, and put electric elements in the air flow to the cabin instead, so the engine takes ages to warm up, but you get warmth in the cabin straight away. |
Going to work this morning, only 3 miles, was at 70degrees. Normally on the way home, slightly different, faster route, 3.5 miles 90degrees.
Gauge starts moving off 50 at about 1 mile. |
Oh right, maybe an issue then? Wonder how big a job changing that part would be :Confused:
|
Carista scan should reveal a problem with the aux. Heater. If a problem exists.
The engine undertrays off mine at the moment and I did notice the aux heater exhaust sticking down. If look in D3 common faults you' ll find all the manuals to download. |
