  1. Hi ShaunZ Going to start from scratch so please dont be offended if this sounds over simplified. The lights are on due to a fault detected. This will be stored in the Electronic Control Unit (ECU). To access this there is a standard called On Board Diagnostics (OBD II as its the second iteration of the standard). There are plenty of ODB II adapters but the one you really want if you are going to have VW group cars (Audi, Skoda etc) is VagCom by Ross Tech Basically you will need to get the car scanned for OBD Errors, specifically ABS and Air Bag, but it will scan everything. ABS Sounds like someone had a go at the Sensors on the ABS and gave up. The sensors are basically Hall effect sensors that produce a signal when passed by a metal object. There is a disc with holes in it that does this for the sensor in the wheel hub area. Trouble is that there is rust, dust, salt and all manner of crud that gets in to these and they will eventually fail. They also tend to rest in place so removing them can be a pain. Think hammer and punch. A scan will tell you wants wrong and go from there. Air Bag Air bags are dangerous. Dont and i mean Dont mess with them with the battery on. They are basically a small explosive charge in a bag to contain the gas that is produced. Its designed to inflate it quickly and have pressure inside the bag for a small period of time as your face and upper body, when restrained by the seatbelt, hits it. They are specialist bits of kit so if it dosnt work then I would recommend getting a qualified mechanic to fix it. That being said the Air Bag light will most likely stay lit until you clear the codes, so again, VagCom is you answer here. Scan Car Save Results Clear codes Scan Car again. Review results. Some codes only return when necessary, some are on until the code is fixed. Ie ABS sensors wont give a signal when stationary so clear the codes and its going to have to move before it can check unless its shorting out or some other hard fault. Remember these are safety systems so just going in and playing isnt something I would recommend, however there is a vast amount of info on the web on VagCom and VWs in general. Disabling Airbags http://forums.tdiclub.com/showthread.php?t=152807 VagCom https://www.gendan.co.uk/vcds-v2.php Im told that ABS fails safe and therefore you dont have a problem with braking just that it will lock the wheels and you will skid. Although I dont have that from a VW source. Also You Tube is another great source - search Humble Mechanic, etc Plenty of things in there to help out owning your VW. Good Luck and remember to update here so if you get it all fixed and someone else has the same problem then they see how its done. D
  2. VR6 12v Not Starting

    I assume it has been working? If you are getting a strong smell of fuel, is it leaking out of the filter before its getting to the engine? Is the filter put in back to front. Not sure if this can cause an issue, but it has a direction arrow on it for a reason. The arrow should be pointing towards the engine. So if you have fuel... Next thing to check is are you getting a spark. If you have a timing light then use this on every lead. I have one that is a non contact one from back in the day when you used to have to time up cars, Google Timing Lamp. about 20 quid or so. HT leads are high voltage so pulling them off and touching the block to see if its going to spark, especially with a "Strong smell of petrol" is not something i would recommend. I had a no start problem on my 98 VR6 and it turned out to be the Crank sensor. The man from the AA said it can magnetize and all you need to do is short it out. Probably getting a capacitance but he did what he did and it started. If your getting a spark, fuel is pumping into the cylinders then next thing is a compression test, but your starting to get in to bigger costs for DIY and it may be a case of cutting your losses and getting a mechanic to look at it. If the car has an ODB II socket get a copy of Vagcom (if you can afford it) and put it on a laptop and plug it in to the ODB II socket and do a scan. There are other ODB II Systems out there but for VW Vagcom is pretty trick. Not sure about the Mk2 as mine is a mk3.
  3. Golf vr6 k reg !!missfire no power!!!!

    I had the Crank sender go and it would turn over but not fire. Called AA and he said they can get magnetised so just pull connector and short it out and off I went. Lambda sensor shouldnt give you too much grief, mine has been broken for ages and it still runs reasonably well. Im told that if the Lambda stops working the ECU ignores it and tries its best to work out filling from its other sensors. May be a bit off, but I dont think it would be that bad.I get pretty good MPG so cant be too bad but then again i drive like an old man as i am one. My first stop would be a Throttle clean, its not a hard job and can even be done with the Throttle on the car. But the overheat is a bit more of an issue.

    1st off, im no expert, but my 2p worth see if your radiator is getting hot? If the car overheated then could be that the thermostat is knackered, since the temp sender is around that area that could be misreading and causing the ECU to overfuel and its running rich? So if you can test the emissions see what its running at. You could have an air lock so check the heater in the car, is it getting warm, if not possible air lock. When cold, Open the expansion tank, start the car and let it get up to temp, if you see bubbles in the coolant then you have air in the system. Dont let it get too hot. If you have access to VagCom then check the throttle position sensor output with the charting function and move the throttle and look for a for a smooth curve, any jumps and its bad. If you have access to VagCom (and assuming it works) then look for Throttle Adaption limit reached indicating a dirty throttle body and if so its time for a clean. Its easy, plenty of DIYs. MAF sensors could be another cause of woes. You could try a clean with pure alcohol or MAF cleaner. Dont use any old stuff its sensitive. Also Look up The humble mechanic on you tube, he's in the states but will reply to questions on email via a pod cast. I only have an ODB II so not sure about what you get on the ODB I cars, but hope this helps.
