negev Posted September 30, 2015 Report Share Posted September 30, 2015 Is it bad for the engine to hold the revs at 1500rpm until it warms up a bit? I often can't see well out the windscreen until there's a bit of heat on it. Quote Link to comment Share on other sites More sharing options...
Ged Posted September 30, 2015 Report Share Posted September 30, 2015 (edited) It's not recommended to warm a car up. Just drive off gently and keep it that way for 5-10 mins (unfortunately there's no oil temp display on our cars...) Driving off will raise the oil pressure and warms the engine up faster. Also driving can put less stress on the engine than running at idle as the components are being moved via the cars forward momentum rather than just the firing cylinders.

negev Posted September 30, 2015 Author Report Share Posted September 30, 2015 There's no point in waiting, in fact, it's not recommended. Just drive off gently and keep it that way for 5-10 mins (unfortunately there's no oil temp display on our cars...) Driving off will raise the oil pressure and warms the engine up faster. Also driving actually put less stress on the engine than running at idle as the components are being moved via the cars forward momentum rather than just the firing cylinders. Right, but my point is, if the windscreen is misty it's not safe to move off because the windscreen is misty.. hence my question about whether it's safe to warm it up a bit by revving it gently.

Ged Posted September 30, 2015 Report Share Posted September 30, 2015 Well it's safe as in you're not going to damage anything, but you will put fractionally more wear on the engine than just driving off. Whether that leads to a noticeably shorter engine life is up for debate. I'd just stick the windscreen blower on full, wipe my screen with a screen cloth and drive off.

bungers Posted September 30, 2015 Report Share Posted September 30, 2015 (edited) Just stick the AC on, should have it cleared in seconds? I agree with ged ref not letting it warm up stationary.

troublesome84 Posted September 30, 2015 Report Share Posted September 30, 2015 unfortunately there's no oil temp display on our cars... You can have it displayed on your dash if you want it mate. 1. Hold Trip Reset while turning ignition key to on position 2. OBC should show "Test" 3. Use Trip Reset to select function 19.0 that unlocks all the features 3. Wait for display to show "Off" 4. Depress Trip Reset for 1/4 second and release it 5. With no delay press Trip Reset several times to select function 7.0 Quote Link to comment Share on other sites More sharing options...
Ged Posted September 30, 2015 Report Share Posted September 30, 2015 Don't you have to do that every time though? It'd be nice if you could turn it on permanently and have it on the stalk. I have an android unit running Torque Pro for this stuff, but I don't keep my OBD dongle plugged in so it's kinda useless for every day stuff.

Jim27 Posted September 30, 2015 Report Share Posted September 30, 2015 Don't you have a demist button? On mine it puts the AC 100% on thr screen and has it cleared within 10 seconds of starting the car. Megadodo 1 Quote Link to comment Share on other sites More sharing options...

dooge Posted October 2, 2015 Report Share Posted October 2, 2015 For someone who drives several different company cars people wiping their windscreen with their hands is common but annoying. There is a treatment you can use on the window to stop it misting up, problem is when its really cold it creates frozen water droplets inside which are a pain in the ass!

I often can't see well out the windscreen until there's a bit of heat on it. says in the handbook ,not to warm up by idling,as said drive normally until up to temp,think its to do with oil displacement ie does not get around quicklyb enoough on idle as oil is thicker when cold and driving warms it up quicker Edited October 2, 2015 by rasa Quote Link to comment Share on other sites More sharing options...
Sam Posted October 2, 2015 Report Share Posted October 2, 2015 Since using autoglym window cleaner on my windscreen and side windows, I've not had to demist at all. Think I'll be using it once a week and enjoying that. Quote Link to comment Share on other sites More sharing options...

kirkynut Posted October 6, 2015 Report Share Posted October 6, 2015 You seem to get a natural grease on glass that builds up and whilst it's not a problem for a while when un touched it becomes a mess when smeared about with a cloth. It gets too much on its own sooner or later and the sun makes it hard to see through. There's no science to this claim of mine. I think they just call it a dirty windscreen!

I laughed far harder than I should have done at this Same here, got some funny looks from the GF. Shame the e46 didn't come with a Webasto heater as an option as per the 5 and 7 series. Just press a button on the remote as soon as you wake up and by the time you get out to your car the engine block is warm and misty screens aren't a problem. Rain X on the inside of the screen is a good solution. Tends to stop it misting up as easily. Quote Link to comment Share on other sites More sharing options...
