simple little question, after adjusting the cab flap close to the 2.5 mm gap, i use less petrol. I only do short trips in towns,...so would consider it as urban. In the book it says it should be 8.7 L/100 K, on line 9 to 9.5 L /100k ? what do you think is a good average? I will soon fill up the tank to the full then drive 100K and refill again to get a good average of what i use now as before it was 12.5 L per 100K !!!! I'm curious of the results,...
It's obvioues to me that you know your stuff ! I've been trying to learn for the last 30 years about these cars doing my best. Your knowleged is a credit to this website and i can't thank you enaugh for everything. I have been looking for years for video's like you sent me and never found one that informative ! I hope my golf will keep going for as long as possible, i do get a lot of attention now adays with people beeping, flashing there lights, thumbs up,...that i never expected. Thanks again, until next time lol
Hi, well it's bizzare, tested the car this morning, idles at 1100 rpm for 15 minutes then goes back around 900. After leaving it to cool down an hour, it starts and idles way too low at +- 600 rpm for about 10 minutes. I think i'm going to leave it be now and stop fiddling as there is a big improvement in any case. Thank you all for all the help and especially the video you sent me that was so usefull to learn about the cab,... the old girl got 89000 miles, first owner from new. I wanted the GTI but couldn't afford it so got the last 1600 cc Driver without power stearing lol.
Well, I don't know how to explain this, may be the weather being so hot? I was up at 8 am down to the car all ready for the mission lol. When i took off everything, i realised i didn't have the right tools to take of the waxstat. I then remembered that 20 years ago ( i got my golf from new ). I actually fiddled with the settings of the cab flap, sucking on the hostpipe turning that wheel,....So i thought, let's check the gap again that should be around 2.5 mm. It was way off ! No wonder i've been using over 12 liters of petrol per 100 K for years when it should be around 9.5 L max urban ( that's all i do ). So to make a long story short, i adjusted it as it should and then lightly gave a few hammer hits on the waxstat ( yes i know, pretty stupid ). In any case, put everything back, started the car, it idled at 1100 rpm, drove 5 minutes, when straight back to 850/900 rpm ? Must be a miracle ! But i will not know until tomorrow morning when it's stoned cold again if this did the trick ! Fingers crossed, Un-real !!!
yes sorry i did test the coolant hoses and they are getting hot. I was just about to ask if it was worth it to take it out and do the boiling water test in the hope of a miracle or improvement,...lol. I will do this over the weekend as at the moment weather here south east not the best,...If i remember well, I only have to take the air filter housing off to get easy access ? thanks again, fingers crossed as this problem just suddently started 6 months ago.
Another test done, turn on the car, idles at 1000 rpm, drive 1 minute, shoots up to 1400 rpm, drive only 10 minutes, come home, still at 1400 rpm. Turn it off, start right away, back at 1400 rpm. Turned it off, waited 45 minutes, start again, idles perfect ! It must be the waxstat ! I'm looking to buy one again but they seem to be impossible to find now. I only found this website but it's out of stock and frankly expensive anyways as i did change it over 10 years ago and i wouldn't have spent that much i'm sure,....Any ideas where i could fetch one ? Thanks. https://www.classic-vw.co.uk/pierburg-2e2--2e3-carb-wax-stat-026129243c-7716-p.asp
Thank you all for your help, while i study the video,...I will try to upload a video of the hole process so you can see how it goes as there is something about the 3 point unit that seems wrong,..will try to show,...I'll update as soon as possible.
Thank you very much for your very very helpful comments and video. I will study this when i have a bit more time. I see you got the same golf as mine and even the color tornado red . I have done my test so basicly instead of driving for 20 minutes for the rpm's to drop back to normal, i started the car, ran it 10 minutes as it does at 1400 rpm+-, turned it off for 30 minutes and started it again and the idle was perfect ! So, correct me if i'm wrong but seems to me the 3 point unit is just very slow to retract ? or is it is the waxstat thing with the needle that is frozen ? I did change it 10 years ago to a metal one instead of plastic,..Food for thaughts,...Thanks again. Phil.
Hi, may be i didn't explain correcty too lol. So when stone cold, start the car, rpm goes to 1100 ( auto choke i guess,.. ), i start driving and after 1 minute, the rpm goes to +- 1400. After driving for about 15 minutes when the temp is in middle and car hot enaugh, it starts to slowly drop back to normal idle within +- 5 min. To answer your question, yes, at that point if i turn off the car and resart it immedialty it idles perfect at 900 rpm and for the rest of the day until stone cold again,... And yes it should be warm enaugh long before all this,...I am going today to do another test as i might have a theory, not sure. I will drive the car for a few miles, it will idle at +- 1400 still, park, turn it off for 20 minutes and see if it goes back to 1400 rpm immediatly or if it will idle fine. I will let you know,...thank you.
Hi all, So after adjusting everything possible on my Golf Driver MK2 1600 cc cab, I got a new problem,... When stone cold in the morning, turn in on, rpm goes to 1100 for a few minutes, then suddently goes to 1400 rpm and stays like this what ever i do for 20 minutes and then goes down gradually back to 900 rpm +-. For the rest of the day, every time i start it, it's bang on at +- 900 rpm. Next day the hole thing starts again !
I have no clue what's wrong ! thanks for your help
Thank you very much, yes there are so many ways to adjust cab that i've done in the past. As you mention people fiddle anyways wrongly . I will try again and do it properly. Thank you for the RPM, this is what i beleived,....
Hi everyone, I got a vw golf mk2 Driver 1990 1600cc cab. First question, someone fiddeled with the cab air/fuel screw on top of the cab cover, now it seems to use to much petrol,... How do you adjust it properly I tried a few times when car is hot but i-m un-sure if i screw too much or too less lol.
Second question, for this car what should the idle RPM be ? I've seen some saying 800 to 850, others 900 to 950 ? What's best ??
I tried a few times when car is hot but i-m un-sure if i screw too much or too less lol.
