Vibration

1262 Views 8 Replies 3 Participants Last post by  eric johnson
I wonder if anyone out there can help, My R75 131 CDTI Auto has a very fine vibration when under exceleration and also when cruising seems as though it has a miss fire, if it helps its a 52 reg and the milage is 65,000 other than that its a great car.

It could genuinely have a mis fire, but it could be many other things. Most notably the rear engine stabiliser bar has worn bushes and the engine is vibrating too much as a result.

HTH, regards, Rob.
Thanks for your help, car is about to have its service so will check out the rear engine stabiliser, as regards what seems to be a miss fire its hardly noticable, a miss fire on a diesel I did not think it could happen but I will stand corrected any clues as to what could cause it.

Misfire is perfectly possible on a diesel, just beacuse the fuel is being injected it doesn't mean it's bening burnt. A lack of compression, incorrect fuelling, incorrect timing and other factors such as heat/cold etc can lead to misfires.

To check the stabiliser bar bushes will require the removal of the bar, if you simply look at it, it will probably appear OK.

Thanks Rob, will be looking into all that you have told me, but I think that some of that will have to be looked at by my local Rover bloke, have had the car from new never been any problems I've been well pleased with it, thanks.

As Rob suggested could be many things, if you can get it on a T4 then that may shed some light on what is causing the misfire.

Hi Simon took in What Rob said, car is now booked in to TR Auto's in Bidford, I now have another small problem I'm sure its connected to my previous problem, always when we started this car you only had to touch the key and it started this last week we are having to actually turn it over I'm wondering if all this is connected and maybe even the vibration when accelerating has some thing to do with the missfire we shall see thanks again, Eric (thats not the royal we of course) it's me and the boss.

Starting problems can be down to many things tbh, Crank or Cam sensor can cause this can't remeber which causes cold or hot starting problems. Does it take longer to start when hot or cold?

Glow plugs can also cause strating issues if they are on their way out.

Injector leakback can also cause starting and running problems, get the garage to do a leakback test although that is usally affected by higher mileage cars tbh.

Hope it helps

Simon, the starting is the same hot or cold but as I say its going in to TR Auto's tomorrow I'm sure they will sort it. , I'm usually good at keeping my car going but with the R75 there's not much I can do when it come's down to engine management it's got to go on the computer, thanks for the advice, Eric
