Car Forum / Volkswagen / Water Cooled Volkswagen Cars / August 2008Re: Idle air control valve or oxygen sensor or what? - SOLVED
I realize this is going against all current Netiquette ;-) but I thought I'd tell you what it was. It was the oxygen sensor *relay*. At least after about 150 miles since it was changed, and the car running just great, I am willing to take a gamble and say that they finally got it right this time. I /tried/ to figure out how much my mpg has improved, but I've used calculators since the mid-70's, and I'm 53 and have been getting stupider (specifically speaking, losing brain cells at an increasing rate) since about when I turned 30 (this is a scientific fact for all humans, no matter how much you may not like it). So I am not at all sure whether my previous calculations (of about 15 mpg) were /anywhere/ near correct, but it would appear I am now getting between 20 and 25 mpg. The 20% margin is because of the differences between US and imperial miles and gallons, and the fact the US appears to have dry and liquid gallons and the UK just "gallons". Is pudding liquid or dry (*after* it's made)? 20-25 mpg is just fine with me. I drive the car less than ever - like once every 7-10 days. (How you guys manage with those insane units of measure is beyond me. I will /never/ understand why anyone would say something is XX Guineas instead of XX £ unless they just enjoy being snotty.) The third Temic coil is OK so far, as well (for those of you with a good memory). Again, thanks to all who tried to help. I am more than ever convinced the whole car repair thing is basically hopeless. How many of you even /knew/ there was such a thing as an oxygen sensor relay? I sure as hell did not, and no one I spoke to /here/ or wrote to "here" mentioned it either. And I certainly will not be surprised if the car doesn't start the next time. Cheers. We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold.

They are obviously affecting your (possibly quite limited to begin with) reading comprehension. I said "I am more than ever convinced the whole car repair thing is basically hopeless." ("Car repair", as in trying to get your car fixed IN GENERAL. If cars were like CD players, you could just throw yours out and get a new one. Unfortunately, they cost considerably more.) Then I /thanked those who tried to help/. I did /not/ say rec.autos.makers.vw.watercooled and similar groups are full of hopelessly ignorant a.sholes. Anyone here knows more than I do, some know more than most mechanics, but no one guessed it could be the oxygen sensor relay. That's what I meant by hopeless, you twit. NO ONE KNOWS. Cars are destroying everything. Watch out, there's a sparkly green/purple one with a oxygen sensor tail right behind you! Wow, is that his brother coming behind him, or did he just split in two? Jeezus. I will say your nickname suits you rather well. > I did /not/ say rec.autos.makers.vw.watercooled and similar > groups are full of hopelessly ignorant a.sholes.

How the f.ck are we supposed to know without having physical access to the car? At best we can give you a list of things to try. f.ck off somewhere else for advice in the future.

Did they say what the function of this relay is? Does it switch between multiple sensors, turn a heater on and off, hand the sensor from cylinder to cylinder??? (aka like in Olympic relays <ugh>) Mark >> I think you should lay off the drugs. They are obviously >> affecting your (possibly quite limited to begin with) [quoted text clipped - 9 lines] > > Mark To the best of my knowledge (it was not explained by the mechanic but I have a friend who is an MD and also a car freak) the relay just processes the info from the sensor and passes it on. The car being over 13 yrs old, it's no big wonder that a small electrical part would slowly start going bad (rust? basic degeneration?). That's what happened - it started about a year ago and just kept getting worse. In the meantime, the coil died as well, but it had nothing to do with the rough idle.

Sorry, you are just off your head. It's you who should be watching the prescription drug intake.

If by 'sense of humour', you peculiarly mean the ability to follow a set of incoherent ramblings, then yes, I was never much good at that. Once you start actually getting funny anywhere outside your own head, be sure to let us know.

It sounds as if you may be using an American vehicle. US spec cars are very different to UK especially in the emission control department. It is quite possible that over here the car is not even fitted with that relay. > It sounds as if you may be using an American vehicle.

It was made in Mexico (most of it, anyway). I had no idea that the same model cars made/sold in different countries could be so different. Just proves my point. It is an endless maze where if you are /very/ lucky, you will stumble upon the exit. vampire chicken <drinking@the.coop> gurgled happily, sounding much like they were saying: > I will /never/ understand why anyone would say something is XX Guineas > instead of XX £ unless they just enjoy being snotty.) Nor me. But then, I don't buy many racehorses. > vampire chicken <drinking@the.coop> gurgled happily, sounding > much like [quoted text clipped - 5 lines] > > Nor me. But then, I don't buy many racehorses. Is the unit still used? A guinea used to be 21 shillings. And if it is still used, what is it now £1.05 ? Mike. >> vampire chicken <drinking@the.coop> gurgled happily, sounding much like >> they were saying: [quoted text clipped - 7 lines] > And if it is still used, what is it now £1.05 ? > Mike.
