Takes a long time for my car to heat up.

    So I an A4 estate the old model. It's a 2.0 TDI but for the first 5 minutes of driving I have to make sure I maintain at least 2500 revs or it takes a good 10 minutes before the car is blowing any warmth. Now this is supposed to be the top model with climate control, I can set the passenger side to a different temperature to my side which is ridiculous madness imo, especially when it can't put the AC in reverse to give me warmth without relying on the engine heat.

    Is this just a diesel thing or this model of car or is it just broken?

    This is a diesel thing. Diesel engines take a long time to heat up. To get around this, many manufacturers have a seperate auxillery heater which runs to provide cabin heat whilst the engine is warming up.

    If you think it's bad, you should try our Caddy SDI. It rarely does a journey more than 5 miles which is precisely how long it takes to start generating any meaningful heat. Modern diesels are unfortunately just too efficient.

    Strangly my 5.0 V10 RS6 doesn't have this issue :D.

    10 minutes till it is up to operating temperature or 10 minutes till you get any sort of warmth from the heater?

    He says 'blowing warmth' in his post.

    its a diesel thing.
    i get heat from the heaters after say 5 mins.
    the engine temp takes quite a while to get even one block on the gauge.

    My Bora reaches 90 degrees within three miles! Perhaps a stuck open thermostat?

    I was pleasantly surprised by the heating in my Fabia diesel. It blows warm by the time I get 3 miles down the road in the morning, after only 5 mins of driving. My old petrol Civic took longer...!

    Nice warm arse, but cold fingers :p Just a diesel thing then, won't be cold for long though I suppose. It only needs to be 10C outside before it's not cold in a car anyway.

    If it had a stuck open thermostat it'd take longer. The interior heater will be on a separate circuit.

    Its due to the fact that diesel engines use cast iron blocks and not aluminium, and so take an age to get up to temperature, one of the drawbacks of having a diesel :(

    If the thermostat is stuck open the water will take a lot longer to warm up. The interior heater shares exactly the same water that the radiator does when the thermostat is open.

    He's said it takes a long time and has to maintain high engine revs.

    My A4 2.0TDI does indeed take forever to get up to temperature, but the auxiliary heater takes care of cabin temperature nicely.

    the vast majority of cars on the road use an iron block, the material used to make the block wont have an effect on the warm up time compared to ambient temp, a faulty stat, fuel used etc
