    Couple of electrical faults - help

    Hi,

    I've just bought a mk4 1.6, and having driven on the motorway for the first time today, the engine management light seems to come on once i get over 40/50 mph (drive in the city mainly).The manual says its not an urgent fault and the car goes into a safe mode, but needs to be checked out. Just wondering if this may explain why the fuel consumption seems so terrible?

    Also, the windscreen wipers are shafted. I can turn them on but then when i turn them off they'll stop in various positions, anywhere except where they're meant to! So i have to spend the next minute clicking the stalk up and down until they stop in the right place. I know its hard to say whats causing the problem without looking at it, but just wondering whether anyone has come across this before or whether it sounds like an expensive job?

    I can answer your wiper problem.....

    As you say they are shafted, very common fault unfortunatly, new motor will be needed

    For the engine managment light it's going to be best to get it taken somewhere for them to read any fault codes that may be stored

    Nice one, thanks for that. Is it likely to be a costly job?

    I believe the wiper motors are around £100

    I'd like to get my hand on a broken one to see if I can fix it

    First of all.... what year is your car?

    If its pre 2000 then youll be able to read the fault codes ur self using a paperclip - do a search for my posts using the word paperclip and all will be revealed.

    If its post 2000 then a diagnostic hook up will be required.

    Personally my money is on the EGR valve - possibly the most common problem on the mk4. Can be cleaned with carb cleaner but more often than not it'll be ok for a short while then go wrong again... Replacement EGR valves can be had for good prices these days.

    Which 1.6 have u got anyway? 8v or 16v?

    Just been reading that, sounds very interesting and i'll give it a go tomorrow. I'm not a techie person so whatever it is i'll have to get a pro to do it, but it'll be nice to know what the fault is and then walk into the garage and tell them what my diagnosis is.

    dont go to a garage!

    if its the EGR which is highly likely - its just 2 bolts - off with the old one - on with the new one - sourced from ebay usually and job done. 10mins max for a total novice

    At least do the test ur self - post up ur findings and then we can advise the best steps to take.

    You gotta start somewhere and admittin defeat at the first hurdle is a bad sign!!!
