Hi guys, I own a 6n2 1.0 Polo and I think I have a potentially expensive problem. Since the last few weeks, Ive noticed everytime I press the clutch in and out, I hear a faint *clunk* (always happen when releasing the pedal), regardless of where the gear stick is. Now its stopped with another problem. Everytime I drive, my car always jerks regardless of whether I have my foot in the gas. It turns out, my car always jerks at low rpm and stops jerking when I drive with the revs over 2000 rpm. When Im stationary, it doesnt jerk and the engine idles fine. When I recorded my engine revving upto redline, the engine remained tamed in its engine mounts (didnt move lol). When I drive inbetween the jerking range, and I press the clutch and coast. The jerking stops. I was also told that my cv boot or joint or gaitor or whatever the black rubber thing that my axles are connected to is called, its ripped on both sides with small leaks. So whats the potential cause of this? Please dont say its the clutch. Please say its just low transmission fluid.
Hello everyone! I've had quite the adventure in the past two years driving this car. It's quite the old car, but I kind of like the character these have. Problems pop up, and go away over time, most of them ignorable, but this one was a nasty surprise. I drive 1995 Ibiza 6K with a 1.4 8v ABD. I know, I know, it's not a Polo 6N but they're very similar so I was hoping if someone would help me here. All of the other SEAT-related forums seem to be just related to the newest cars or just downright dead. No help whatsoever. :/ I once again apologize for it not being a Polo, I just can't find anyone with this specific problem. What happened prior to the problem: The other day, the weather is damp, and the car started oscillating it's revs in a rhythmic way between 750 and 1200 rpm (idle and warm up revs), it is about to stall, but then it gives itself some throttle and goes to 1200 but then stalls to about 750 and throttles itself again until I intervene with a quick blip of the throttle and it goes away. It was odd, and enough to get my attention. After about a month, I decided to reset my ECU, so I disconnect the battery overnight and after 24 hrs I reconnect it and start the car. I let it run and it got down to 750. 10 minutes later, down the road, I stop my car at a stoplight, and it starts oscillating again, I blip the throttle, and it just revs itself to redline! It does not take any throttle input anymore, and I just cut the ignition. I start it up again, and it revs itself again to redline. I was afraid to dump the clutch to see if it would keep going, but I pushed the car to the side of the road and tried to see what was going on. The mechanic replaces the throttle actuator, and it went away for 15 minutes. Second replacement, 600RPM and it was away for 10 minutes, then the 3rd one was okay for 3 weeks. Now, I was having some short-lived fun, where I used full throttle, the car pulled no problem from 2000rpm to 5000rpm. And 2 minutes after that, at a carpark it's idle went from 750 to 1000, and when I tried parking, it again went to redline, same problem, whatever I try (it was wet outside again). When I turn the ignition on, the butterfly valve is wide open, is it supposed to be like that? I've searched high and low for answers, from one forum to the next, 2003 to 2015, I've learned how Monomotronic/Jetronic is supposed to work, what inputs it takes in, how it operates and whatnot. My mechanic has a parts car, so I can get replacements right away, I just don't want to burn a hole in my pocket (it's charred as it is :/) The car sits for 3-5 hrs and the problem goes away, but I'm afraid to make any longer journey in it. Can the actuator even push the throttle body all the way to wide-open? Could the ECU be knackered? I understand that all it takes is a small short circuit between the contacts on the ECU and the actuator goes out all the way, but W.O.T.? No way. I'm lucky it's not an automatic. If anyone can help me narrow down the possible problems, I would be very grateful! I have heaps more info I got from observation research of the car, but no-one had a W.O.T. problem like I do. P.S. The MPG was usually 26, but during winter it drops to 14. Any help with that would be good as well!
