2013 Dacia Duster Laureate 1.5 4WD - Coasting - BeeJay71

Hi all,

The manual states that my Duster mustn't be towed with any wheels in contact with the road. But, what about coasting? A 4x4 being towed whilst all wheels are in road contact is surely the same as coasting, the only difference is, when coasting, up to lights, etc, the engine will be running. Does that negate any malfunction with the running gear?

Thanks in anticipation.

I wonder if there's some issue regarding adequate lubrication in the drive train if drive isn't coming through the input shaft from the engine, this is why lorries and buses arn't towed any distance with the drive axle on the ground without a half or prop shaft being disconnected/removed, even the manual boxes have their own oil pumping system.

Another issue might be to do with the centre diff (of whatever design it might be), without the electronics doing their thing, or again the input shaft needing to turn, i wonder if there is danger of transmission wind up or something on corners.

Coasting is different, usually only applies for short periods of time, sharp turns seldom apply and in almost all cases the engine is running the input shaft turning and electronics still live.

Thanks gordenbennet,

I think you're dead right about the towing etc & also about the coasting, as the engine would obviously be running. Unless someone knows different??

Towing a car, usually for some distance and at moderate speeds, is completely different to slipping a car out of gear for a few hundred yards at most.

I THINK my favorite UK coast (A83 from the top of the "Rest and be Thankful" pass down to Arrochar) is several miles long (havn't measured it) and I know it can be done the whole way engine-off if you don't have (or can do without) servo-braking.

I wouldn't be surprised if there are longer ones in Scotland, but that's the best one I know of. You need to keep your nerve and avoid braking where the road kinks across the burn, to conserve momentum.

I remember driving down that road in my 1946 Rover 16. The brake fade from the all drums braking system was fierce and the smell was vile.. Quite scary..even with a lower gear engaged...(It had a freewheel fitted but I locked that..)

If you don't brake, you avoid that problem :)

Ah, a freewheel...I would love a freewheel. A neighbour had an old SAAB 99 that I coveted which had one, but he said it scared him so he didn't use it. Waste of good machinery.

It gave him some problem with the handbrake (bit complex on those because its on the front (driven) wheels) and he scrapped it.

I'd moved by then and didn't find out until much later. I bet I could have fixed it without too much trouble.

Some people don't deserve old cars.
