Hi all,
My cousin has asked me to try and fix his freelander and just thought I would see if any of these symptoms rang any bells with you lot before I start the trial and error approach.
He says: Its an intermitent problem, Sometimes when he gets to some traffic lights the revs will surge while idling, then when he tries to pull away it lacks power to the point where the engine will die if he is not careful also black smoke coming out of the exhaust. He also says it will sometimes start with the black smoke randomly when cruising ( Not just when accelerating ) . No warning lights on dash board except for the traction control light ocasionally. Its had a new air filter recently, fuel filter was last changed in 2013. egr valve has some oily residue but not restricting air flow that I can see. There is no other service history with it so I assume its not had a crank case breather filter recently, if ever.
I have had a look at the intercooler pipes and cant see any splits or soft spots.
Just wondering where to start really, The breather filter? fuel filter? egr bypass kit? The reason I mention the egr bypass kit is because a local mechanic has said he thinks it is the egr valve causing the problem, I thought it would be the intercooler pipes but I cant see anything wrong with them.
Oh and he also said that giving it a good rev sometimes temporarily cures the problem, when I looked at it earler it was black smoking when I revved it while it was parked on his drive.
Any help or advice would be much appreciated.
Thanks in advance,
James
