    Hi all

    My name is Cannon, im from Portsmouth

    I recently sold my 400bhp 200sx s14a BN drift car and stepped into the world of German motoring in an attempt to grow up

    However I have noticed that on my 2002 745i v8 e65 bmw when the car is sat idle for a while and then i pull away i get a puff of smoke out the rear the size depends on the time idle.. (car has a full bmw SH and has just ticked 95k miles on it)

    but after being sat for about 10 minutes in traffic today and then putting my foot down in sport mode i managed to create what can only be described as a wall of white/grey smoke behind me

    now ive had a v8 range rover in the past and ive owned car before where the head gasket has been on its way out, but apart from the smoke there are no signs of this (i.e creamed oil etc)

    just wondering what you guys think it could be, I have been researching all the bmw forums to locate an answer and to be honest dont want to go to BMW and get charged a fortune for someone to just say you have bought a dog

    anybody else on here had issues with the 745i e65's smoking on pull away???

    only had the car 2 weeks and it doesnt seem to have lost any oil and apart from the smoke its a joy to drive and be in (got alot of the extras including the air cooled seats etc)

    but wondering if its worth me getting an oil and filter service done on it and getting anything else checked like breather pipe etc?

    Many thanks in advance for any help

    Somethings definitely not right there, a petrol engine shouldn't be making smoke like that.

    Are you sure it was smoke and not steam?

    Maybe worth giving it a service and makeing sure there's no water in the back boxes..

    Just seen it in the above post, excuse me it is late lol.

    Can be anythink really, im thinking coolant is being burned or valve stem seals. But a compression test would be a good idea to get done.

    I was thinking stem seals but its pretty rare on a German car and with only 95k. Could be a dirty EGR..

    I have heard the term EGR before and one of the symptoms i was told about was the same issue with smoking on pull away as I have

    Also from what i can see there seems to be alot of oil in the engine could this also be an issue.. it seems to be over the red makers on the dipstick

    how much and how difficult is an EGR to change

    Overfilling a engine with oil is just as dangerous as underfilling. How long has it been over the marker?

    Try disconnecting the vacuum pipe to the EGR (plug it with a screw or something) and then take it for a test drive. If its cleared up you'll know its a dirty EGR and intake manifold.

    And i'd drop a bit of the oil soon as, how much over the max mark is it? Some people say its okay upto 1-2mm over but I never take it above, it can cause all sorts of problems..

    The trick is to check oil levels with a cold engine not running. If it is warm and running. You will measure a lower oil levels than actually. And be delued to think it is time add some oil.
