  1. Hello, I´m from Brazil. I have a Polo classic (6KN) and buied a VAG-COM to access the ECU. What parameters i can adjust with Vag-com in my car? The engine (1.8 liter M.P.F.I - Gasoline) and ECU (MAGNETTI MARELLI 1AVB) is similar with Golf MK3 inBrazil.
  2. Hello, I have a problem with my 9N in that last week the temperature warning light popped up on the dash and now I don't seem to be able to get rid of. I'll try and summarise here: - temp warning light came on - it was a hot day but temp gauge read 90 (as it should) and the coolant level was fine - pulled over and engine cooled to 70 - started up again and all ok. then warning light came back on after 1/2 mile. Coolant temp and level still fine but I waited a little longer - started again, light came on again, but I just drove home anyway because I didn't believe what it was telling me. Got home fine and the temp gauge didn't get above 90 Since then the light has come on randomly. Sometimes not at all. Sometimes 10 seconds after starting. Sometimes without starting. So, my thoughts were that it's either a problem with the temp switch in the stat or the coolant level sensor. Or maybe the ECU (I'll get to that)? I unplugged the level sensor, cleaned the contacts, and reconnected after getting a good resistance reading (not open circuit). Started the car and it was fine. Shut the drivers door and stood watched the engine for a few minutes. Went and checked dash, still no light. Job done. Then I opened the drivers door and the temp warning light came back on with the interior light. And strangely since then driver elec window is manual only (if i press the button all the way it doesn't open on its own - I have to hold it down). This door business is making me think it's maybe an ECU fault. I'm happy that the car isn't overheating and that the coolant level is ok. There's no leak. There's no oil in the water. The temp gauge has never gotten above 90. Could it be that maybe it did overheat and the ECU is confused now - it thinks it's overheating but it's not? I have a new coolant temp switch to try, but I'm not convinced that it the problem. I think it's electrical but I don't know where to start with checking. Was tempted to get a VAG COM cable but I have a mac and don't really want to install a partition for windows just for diagnostics. Sorry, that's an essay, but it's not a straight forward problem. I'd be very grateful if anyone else has experience of this sort of problem and has anything they could share. Is there anything else I could try myself before I concede and take it to a garage? Thank you kindly.
  3. Hello, im looking for the ECU diagram for a AUD engine for a 1.4 8v 2001 polo, Bosch ECU: 030 906 032 DT. Any help is apreciated, thank you.

    loom swap

    I've found a "Mk2f polo fox coupe 1993 1.0 spi loom and ecu" advertised for ~£60. The loom on my Mk2f breadvan 1.0 has had someone go at it with all manner of scissors, tape and random bits and bobs. Obviously everything was done with good intentions though the back of the radio is a plate of spaghetti and there are a couple of loose ends hanging down in the drivers footwell. The radio has the reg from a 1980 escort so is obviously a replacement, 99% sure that the fitting is what caused the spaghettification of the wiring. I am very much a novice with car repairs and am by no means an electrician. A- would this even be compatible with my car, as it is a breadvan and not a coupe B- does the loom incorporate the radio, i.e would it be the solution to the dogs dinner hiding inside the dash. basically, the issue is that I have a radio that has been shoved in leaving the wiring a mess, will the loom from a coupe fit a breadvan?
  5. The last car I had was a 1988 Polo about 20 years ago and I've had nothing but old motorcycles since. However, I've just bought a 2000 Polo Hatchback 5-door with the 999cc engine in the most basic trim with nothing optional included, which suits me just fine. Roll-em-up windows and basic simplicity. I bought it from a dodgy bloke in a pub car park in the dark for peanuts and he said it was owned by a little old lady who only ever used it to drive to church on Sundays. It has no body rot (VW galvanized that year) and it has almost a year's MOT left. So it's basically a 20 year old car with a few minor niggles that people who don't work on cars would find daunting or expensive to fix, but I've been working on vehicles since before you were born so I don't mind a little upkeep but I've never owned anything as new as this and have no experience with things like fuel injection, ECU foibles or what the MOT man looks for these days so I need a little advice on a couple of things. When I first got it the idle was erratic to say the least so when I got it home I popped the bonnet and took off the air breather and found ancient leaky air hoses and random electric shite which I started removing and throwing away. I've done stuff like this to vehicles for 40 years and they are always better for it. A petrol engine isn't rocket science and all that so-called pollution control complication is rubbish, and breathing crankcase fumes and who knows what back into an engine is stupid and unhealthy for the engine. That idiotic massive air breather that probably weighed more than the driver's seat had to go in the bin and a small motorcycle pod filter the size of a coffee mug went on. I plugged off the two air lines to the throttle body and rerouted the crankcase and valve cover vent hoses so nothing goes into the intake anymore. After scrutinizing the fuel lines and figuring out what they probably did as regards the injection system I disconnected the electric tank breather valve and threw it away and removed the plastic cannister thing down by the radiator and now the vent hose from the tank is just open to the air so the tank can breathe. Then I dumped a gallon of diesel in with the petrol to clean the injectors. Worked a treat. All that made the car run sweeter than I'm sure it has in ten years. Idles perfectly and goes strong for what it is, which is a 20 year old 50hp petrol engine so you can't expect anything wild but it trundles along brilliantly now. Absolutely no problems there. I hate the fly-by-wire throttle pedal and see no reason why it was even used on so simple a car but I know it has to stay for now for the ECU and the fuel injection to work, at least until I can source a cable throttle body and a different ECU to match or a carb and intake, but for now it will stay as standard because it works. However, what I'd like to know is how much crap can I get rid of before the ECU starts to complain or something? For instance there's a temperature sensor located down by the distributer that I've read often has issues either with bad wires or erroneous readings and that somehow causes the ECU to misbehave, so can I just get rid of it altogether? I won't use a thermostat in the engine so the water will always circulate freely anyway, so what's the temperature sensor even for and why does the ECU need it? I'd like to just get rid of it and be done with any future problems. Then there's the idiot sensor bolted into the exhaust manifold. Stupid crap, needs to go, is there any way to dispense with it and still have a happy ECU and still get through the MOT? And the strangling old catalytic converter is coming off as well as soon as I can find a fake straight through to fit because I know the MOT says this car MUST look like it has the pointless thing fitted. I have read things about the immobilizer going bad as well. Where is it, and can I just get rid of it? The simple primitive stuff I can fix, like the brakes and the suspension that need a bit of sorting before the next MOT, but primitive as this thing is it's still got an annoying amount of senseless computery crapola and I'd like to do away with as much of it as I can. Otherwise, it's a great car!
  6. I hope some one here can help me please, I have been trying to find any info through the search option, but maybe I'm asking for the wrong topics? I can't find what I'm looking for and am desperate to get my wheels back on the road, my ability to work depends on it and I'm on a low budget, so I can use any help I can get please So the problem is, a non running 6n2 1.4 16v estate from sept 2001, engine code AUA the starter motor works, full working battery, alternator, sparks, plugs, fuel pump etc all work, she's been temperamental in wet weather due to the crankshaft sensor having corroded cables, which was only a problem in wet weather, once dry she'd run fine, LITTLE bit of varying revs in idle, but never let me down Then 2 weeks ago, I got her started, reversed out of my space and she simply cut out, not to be started again, starter motor turns over but no sparks So finally I got a new crankshaft sensor, thinking that was the problem, and which was easier to replace then anticipated lol, but still no luck, my car was parked up at this time half an hour away from me and getting there was tricky, so I managed to get the AA out yesterday who had a very thourough look and tested all sorts and he suspects its the ECU, now I know due to its position under the window wiper arm its very possible its water damaged and I am looking at replacing it, which will be my first question, having done a lot of googling, I am led to believe that if I have a 'virginised' preowned one, I can just plug it in and it will sort itself, does anyone on here know if that's correct? Or will it need remapping? My second question is, before I spend more money on parts that aren't the cause, could it be anything else then the ECU? I've read many posts over the last 10yrs of owning 3 different Polos, and am aware that there are several faults that could cause similar symptoms, I'd just like some advice of you knowing peeps, do you have any experience with this and please can you help? With kind regards, Vivian
  7. Has anyone used a tuning chip on a 1.4 8v 6n (AEX)? There’s one advertised online for about £50 and states a gain of 6-8bhp with improved fuel economy, less flat spots etc. Trying to figure out if this is snake oil or will genuinely get a bit more fun out of my little engine. any thoughts?
  8. Hi, just wondering if there is an ecu on this as I’m looking at buying a 1989 mk2 polo s. Been quoted insurance for a black box but I don’t understand how they would fit it if there is no ecu? Thanks for any help.
  9. I have recently bought a second 1L 6n2.... this one is in beautiful condition with only 82000 miles But the previous owners father left the key in and flattened the battery and in trying to jump start he got the jump leads crossed and blew the ECU........... I have replaced the ECU with one I bought on ebay (same part no. 039 906 032 bc)(ALD engine) Now the car tries to start then cuts out immediately...... I presume this is a immoblisor/ECU pairing issue.... Can anyone please give me some guidance ?
  10. I have a 3 cylinder 12v 1.2 60 bhp polo I can't imagine there being a difference in the 3 cylinder 12v 70bhp polo apart from ECU so my question is can I swap the ECU and would that get my the bhp gain I know it isn't much but ?
