  1. 2004 Bora 'Emissions Workshop' 
    #1
    ajbaker Guest
    Hello all.

    Two months ago I purchased a 2004 VW Bora 1.9 TDI 150 Sport from a small car dealership. The car came with a 3 month warranty provided by a national warranty provider, and not from the garage itself.

    Last week as I started the engine from cold the 'Emissions Workshop' warning was displayed, along with the engine warning light in amber. These warnings were displayed constantly for two days, until half a mile into my journey the warning disappeared. After the weekend, the warning reappeared but has since gone out again.

    I understand this warning suggests I should have the problem identified soon but am ok to continue driving. Obviously I do not wish to spendd £80 with VW to identify the problem - where else can I look to have a diagnostic check? Secondly, does it matter that the warning has since disappeared? Is there a 'log' of previous warnings or is the data only available when the warning is on?


    Also, I understand from reading other threads the warning could be displayed for any number of reasons. However could it be related to glow plugs? The reason I ask is when I start the engine, usually the glow light disappears after several seconds. On four of five (only) occassions since purchase (2 months) the light has not gone out at all, and I have turned the ignition off and then on again. On these occassions the light has then gone out after a few seconds are per normal.


    Your thoughts appreciated. If it helps at all, I live near Newbury and work on the south side of Oxford.

    You need to have it read for fault codes and for this you do not have to take it to a VW dealer, any garage with fault code reading equipment will be able to do this for you. The most likely cause of the problem will be a coolant temperature sender fault which is quick and easy to replace.

    Many thanks to you all for your responses. It seems the most sensible thing to do, as always, is to do it yourself! Shall invest in cable/reader myself. Steverob1983, might I ask where yo got yours from and if you would recommend?

    Out of interest, can I only read the fault if the warning is currently 'on'? Reason I ask is it alternates every couple of days...

    I got mine from ebay for about £25 you can get a trail/shareware version of vag com from ross-tech.com. the trial/shareware version lets you read the fault codes and such but doesn`t let you change or tweak anything.

    The memory is non volatile and codes generated stay in memory for at least 80 cycles without the issue re-occurring, in theory!

    I have known codes to vanish though.

    Once again, many thanks for your responses. I eventually purchased a usb cable from eBay (£16) (which is just a USB to serial adapter unfortunately) and armed with the VAG-COM software (and lots of faffing trying to get XP running on my Mac) was able to read the fault code from the car.

    Crasher you were absolutely correct, it was the Coolant Temp sensor that has an intermittent fault.

    You said it was an easy fix? How easy is easy for someone is DIY competent but has now tools for cars? And more importantly if I did fix it myself, would the warning disappear or would I still need to clear the code myself?

    Thanks once again.

    Very easy. The part number is 059 919 501 A and it is in a plastic water housing on the left of the engine above the gearbox. It is held into the housing by a plastic clip. Release the system pressure before removing the clip and the engine MUST be cold. The "O" ring is N 903 186 02.

    You have a boost leak, a split or disconnected boost hose or split intercooler.
