Hi I have just bought a Megane 1.9D it has just had full belts, injector cleaner & filters all the glow plugs are good. My problem is the first cold start of the day is aweful seems to barely fire on 1 or 2 cylinders for first few seconds. occasionally I get diesel knock a minute or so after first start on load
2000rpm low gear. once the car has run for 2 or three minutes everything is fine and dandy smooth running no excessive smoke 48-50 MPG. This only seems to happen when left for more than 12 hours and air temp < 6 degrees.could it be a leaky injector? If so what to do :-(
any ideas welcome.
TIA Jim
