Push starting a car

That and to reduce wear on the DMF.

Spinning the input shaft of the gearbox with the flywheel from the starter is going to add negligible extra load, compared to the compression - especially on a diesel.

I'm not saying I agree with the science, but it's recommended practice and one of the reasons a manufacturer I work with tells me they include the clutch switch on all their vehicles. I assume they know what they're talking about, as they make *quite a lot* of cars.

Because a lot of modern cars have a clutch switch that needs to be engaged - by pressing the pedal - before the starter'll engage. No press? Turn the key and no starter. The intention is to stop numpties from starting in gear and lurching forward.

Sorry, I did misread it. I now know what you mean.

i can think of several cars that risk damage by bump starting, risk of belts or chains jumping. Or a lack of oil pressure for tensioners and valves etc.

Hi

I remember reading somewhere about unburnt fuel etc not being good for a catlyser, and not to tow or bump start, use an additional battery.

NO I cant explain if it cranks and cranks on a battery is not that the same thing? I didn't write it I only read it somewhere.

And this is why the very first mod I do on any car, is to change the interior bulbs for LED :cool:

Aye but one day you might get married and have kids and then all these small things are a PITA.

Isn't it MSE just not to leave the interior lights on?

How do people do it? If it's dark enough to need them, wouldn't you notice when you look at your car, or do people not bother to check their doors are locked as they walk away?

I don't know about you or anyone else, but when I lock my car the interior lights stay on for around 30 seconds.

Mine stay on until you lock the car, then dim out on locking. Most cars are the same to my knowledge, I've never known one that just leaves them on once the car is locked, what would be the point?

Some just go off instantly the door's closed.
Some start to dim instantly.
Some have a delay before they start to dim.
Remember - they do that if you're getting in, too, so it can be a useful delay while you put the keys in and put the seatbelt on.

Or they stay on permanently because some numpty knocked the switch...

I'm aware of how interior lights work fella. My point is still the same, I've never come across any that stay on, timed or otherwise, once the car is LOCKED.

Getting In the car is a different matter. Strider reckons his stay on for 30S or so after the doors are locked, and that's not something I've ever seen on any car. As I say, what would be the point in interior lights being on a delay after you've locked the blasted car?

Perhaps you missed my last sentence.
