    Sounds like water vapour burning with the exhaust gases, this gives off the white cloud, unlike black smoke, which is oil mixing with the exhaust gases.

    As the engine is also down on power, could be a head gasket leak causing this.

    Best bet is to get her to either a good diesel mechanic (someone recommended to you) or sink your trust into a garage, again better if you know them or be introduced to them, though this still wont be a barrier against being ripped off.

    Just as an aside, is there anyway a small amount of petrol was put in the tank? hope not.........

    could be glow plugs, hard started white smoke is unburned fuel being expelled, or it could be head gasket gone blowing steam out the exaust

    since posting earlyer i've been told it could be an air flow meter symtoms very similer :/ no chance petrol got in i put 10 euro of diesel in just hours befor this started :/ the car is hard started when warm so would that not rule the glow plugs out ?


  • Registered Users Posts: 2,574 ✭✭✭dharn


    YA THAT WOULD RULE OUT GLOW PLUGS.


  • Registered Users Posts: 245 ✭✭Migworks


    and i spent three days arguing with my dad over a mysterious problem that stopped our old van dead, and what was the cause? He put a small amount of diesel in our petrol tank and that was that lol.

    Air sensors can break down, although modern cars running ecu's usually have a default mode when a sensor goes, allowing you to continue driving (get you home mode). Not sure if it would cause the smoke? When you start her up (or him 8@) ) and its pumping out the white smoke, put your hand near the tailpipe, does it become very wet??? lot of moisture coming through is water getting into the exhaust system.

    A well kitted out mechanic will have a pressure tester he can rig to the engine and it will show up any head gasket leaks.

    Good luck fixing her (or him) :D

    im takeing HER to a machince friend tomorrow :) the white smoke is not moisture anyway but the head gasgate was done not so long about so that should be ruled out aswell ?
    a friend of mines mk4 golf went and it showed very similer symtoms dead hard to start and white smoke :/ btw i feel cars should always be her :P


  • Registered Users Posts: 245 ✭✭Migworks


    well, the head gasket might of been done before, but unless the head was skimmed (adds to the cost so a lot will chance not doing it) it might be going again.

    See how you go mate, hopefully your bud will identify the prob and its a quick cheap fix.

    And cars will always be a SHE, mainly due to HER being very good at emptying our wallets!!!:P


  • Registered Users Posts: 129 ✭✭d o'c


    whats the coolant level like.

    if it is head/ head gasket symtoms again,
    get the head pressure tested.

    if the car was badly overheated before (the previous HG), and the head gasket is gone again then change the head

    replace the coolant temp sensor, buy a genuine one, they are about 30 quid and easy enough to fit

  • Registered Users Posts: 2,574 ✭✭✭dharn


    doubt if its that simple, white smoke when cranking is not good


  • Registered Users Posts: 17 RoSparrow


    tbh it sounds more like the turbo with the white smoke and down on power.
    Did u check the oil level id check that straight away


  • Registered Users Posts: 594 ✭✭✭fanadman1


    an update for everyone :P
    it was only dirty diesel :D filled it of clean white diesel and the mechaince put a bottle of stuff in it to clean my injecters within 3 miles everything was perfect again :) no smoke power back again and starts nb :) makes me want to name and shame the garage but don't know if its aloud on boards :P

    .

    Black smoke is not oil burning. Black is unburnt diesel, normally caused by a lack of air or excess of fuel

    Oil burns blue.

    White smoke was often attributed to timing issues.

    Again, turbo will not cause white smoke.

    Glad to hear she's motoring again. Them auld VAG 1.9 TDIs are hard to kill. :)

    I'm puzzled as to what lead to the dirty diesel diagnosis. Was there excess water in the bottom of your fuel tank? If so why didn't the fuel filter catch it? Did he change the filter for you?

    naw never changed the filter he had none in :/ well i had thought about it being dirty diesel because i had only put 5 euro in at a pump befor this started and there was barly any left in the tank :/

    It is, I do!
    Was being general with the smoke issue regarding colour, no point being overly technical. Your right in that unburnt fuel gives off a darker smoke, burnt oil is more bluey, but was just giving the opposite of the white smoke. Alarm bells went off when it was mentioned that the head gasket was done recently, but thankfully it turned out to be something more simple (having the car in front of you does wonders for helping diagnosis).

    I thought that Boards were a way of communicating with a broad spectrum of people on a multitude of issues and not just for an elite few who may or may not be in a particular trade. I accept that on certain issues proper correct info is required rather than guess work, but as I did not have the car in front of me, and was given only a few symptoms having an educated guess is all I could offer. I did point out that ultimately he should seek advice from a known trusted mechanic or visit a trusted garage.
    And that is the proper advice anyone can give in a matter like this.
    Now roll your eyes back down buddy and put yer wooden spoon away =0>

    Rant over 2......

    OP , glad you got it sorted quite easily in the end. Never drink the dregs of the keg, eh!

    Slidey, in fairness to the suggestions on turbo issues, some of these earlier vintage TDI systems in Europe had adopted the Turbo Encabulator technology derived by Chrysler originally.
    In troubleshooting, it has fooled many's the experienced technician yet alone hurlers on the ditch.

    For those not familiar, a short video outlines basic principles ......

    All good in the end.
