  2. 6cyl engine mess

    in Engine Maintenance and Problems

    Posted

    Just an update for all interested.

    Car seems to be running ok now, and original ecu has been sent away for testing so will report on the finding when i know.

    ECU based immobiliser is reprogrammable via vag com, and takes about 20 seconds to do.

    I have thread details if anyone wants/has to do it.

    Regards.

    Hi folks,

    Just an update on the car.

    Aquired an ecu, reprogrammed the immobiliser in the ecu, and off she went....For the moment.....

    I spoke to stealth which was enlightening, suffice to say i will be going there in a couple of months for another remap!

    Oh and i now have belt and braces - AA Breakdown cover!!! Bet it wont miss abeat now.

    Thanks for all the help everyone.

    Regards

    Thanks for the replies folks....

    Wanted your oppions before i told you that i thought it was an ecu problem. I have a known good ecu coming tomoz so will plug it in and try.

    As far as the map, well i know alot of people slate superchips but the map in it is ALL GOOD, the guy who mapped it put the corrado map in mine because the 'standard' golf map didnt have enuff fuel for my car at the top end, so thats why i have a corrado map. Its a shame as this will be the second ecu in 3 yrs. When i got the car it was a bit flat, after alot of time on the rollers it was traced to faulty embedded code in the ecu, so i had to get a new one from germany.

    Ho hum.... Will try the moving the ecu plug/wiring around later on. Once again thanks for all the help so far - will keep you all posted!

    Hello there, just after someone shedding a little light on my problem ;)

    Right then this all started about 8 months ago, took my '97 golf vr6 to the body shop to get the sill welded for the mot. Had the work done but the car wouldnt start at the body shop, tried vag com, but it wouldnt communicate. Towed the car home, eventuall took the ecu out and checked feeds & earths all ok. Pluged the ecu back in fired up and checked vag com again, communicated fine and no logged faults. So then we move on several months, the car refuses to start again, take battery neg terminal off for 30 mins and reconnect car runs fine. Disconnect and reconnect again car runs on 3 cyls really rough, but NO faults on vag com (ive soaked the coil packs at night and there aint no tracking). Disconnect leave 30 mins reconnect and alls well.

    Still with me?!?? We now move on to this month @ bristol volks fest. Car drives fine to show, on way out it gets uber hot and 2 miles down road it cuts out. Stop for 20 mins and it starts again fine and we get home. It refuses to start a few days later again vag com refuses to communicate. Do the batt thing and it starts again. Then a few days l8r it starts then stalls, with the engine not running the tacho is jumping between 1500 and 2500rpm! Oil light is flashing and f/pump relay is rattling in and out all the time, switch ign off and turn on again and it still doing the same. Vag com wont communicate! So disconnect the battery and it starts again. So we move onto today, my girlfriend took it to work, it got her there but wouldnt start to come home - battery trick wont work this time. I got to it try both keys (to rule out a key transponder prob) still wont fire. Disconnect ecu check feeds/earths - all ok - plug back in it fires and runs, try and drive it out the garage and it stalls and wont start :@

    Please help me as i dont like using the car now as it is unreliable, and i dont want to resort to a gallon of petrol, matches and an insurance claim.

    Its done 61K miles ecu was replaced 2 1/2 yrs ago, and is running a superchip with modified corrado map, ram air filter and jetex exh!

    ECU is running motronic v3.8.1 AT v0.4.

    Thanks.

  9. Cleaning mass airflow meter?

    in Engine Maintenance and Problems

    Posted

    I saw something on vw vortex.

    Put in a plastic bag with IPA and shake, allow to dry naturally.

    Dont take my word for it have a look yourself.

    This is a quote from the site have a look yourself it is in the tech section under the 12V vr6 bit, FAQ's near the bottom.

    How do I clean out my mass air flow sensor?

    Take the large Ziploc bag and place the MAF sensor in it.

    Pour enough Isopropyl alcohol into the bag to completely cover the MAF sensor. Gently shake the bag to allow the alcohol to pass through the sensor. Take the MAF sensor out and let the excess alcohol drip off. Set the MAF sensor down on a paper towel to drip/air dry. You may want to use the compressed air spray to blow dry parts such as the connector port. Allow the MAF sensor to dry completely before reinstalling it in the car. This will take between 1-12 hours. Reinstall.

    Aint tried it myself but.....

  11. Cooling system noises

    in Engine Maintenance and Problems

    Posted

    Hi

    Just a quick one that hopefully someone knows the answer to!

    The car is a '97 with 51K on the clock.

    In the past couple of weeks i have noticed that when i sit in the car after the engine has been switched off i can hear gurgling noises from the cooling system, thought it was an airlock, tried that but no different, any ideas? It doesnt seem to be using water and is running sweet.

    Help.
