BMW 118 D sport, feels like it's running on 3 cylinders, vibrating badly especially on idle,no fault lights on dash, used to come and go but now permanent. Garage unable to find fault after compression and vatios other tests. They have now sent the injectors away for testing. Power almost normal but running very rough.
Hi Shantal,Have not had an answer to my question and still need expert advise !!
Thank you ,
did you get my previous e-mail ?
I have not had a response to my original question !!
I have told you all this in my original question,
no fault codes
compression on 3 cylinders normal
one slightly down but not by much,
I shall be talking to the mechanic tomorrow and will let you know anything else relevant.
Why don't you hazzard a guess?
thank you for your advise,
the problem with my car still hasn't been solved,
they are now talking about the flywheel and associated components.( at
ALLAN ASTON (Bosh agents in Evesham )
I shall keep you posted,
Thank you for your help so far,
Might have to take it to BMW in the end.
If your gearstick is rattling this is another pointer to this being the problem.
There are no horrible noises and the gear stick isn't rattling just badly vibrating,
listening to the engine sounds almost normal , maybe a little noisier.
vibration worst on idling improving with acceleration
will I be charged every time I as you a question?
Still haven't solved the problem.
Check the hose clips for tightness and inspect the trunking for any cracks or splits and also all the vacuum system, the small bore pipes and fittings for cracks and missing parts.
The best way to locate a leak is to have the engine running and warm and then spray lighter gas around each joint in turn. If the engine rev's up you've found your leak.
Work your way through each possible joint one at a time and you should find it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to provide a spraying 'wand' and allow a direct blast of gas into each area, especially those difficult to reach with large implements.
Might also be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can do a quick fault find if you unplug the meter and run the engine without it.
if the engine condition is the same then chances are the meter or the connection to it is faulty
its also worth cleaning the airflow meter by removing it from the car and spraying the exposed sensor wires inside the tube with a brake or switch cleaner - ensure that the cleaner is one of the old fashioned, non Eco type that does not leave a residue
On no account touch the sensor wires with anything physical as they are extremely fragile
sorry to be so long winded but the car is still at the garage and is not sorted yet,
I think I might have to take it to the BMW dealer.
Should know more on Monday.
Thank you Matt,
my postcode is:
around Worcester ,Pershore or Evesham would be good,
the car is with " Bosh Allan Aston " in Evesham at the moment.
