Hi
Had problems starting my digi 8v yesterday. Had to call the AA man who said it was something to do with the fuel supply. He thought it was just because it was low on fuel but after filling it up the same happened this morning, and the car runs rough as anything now. Was so nice before :cry: This happened suddenly yesterday with no warning. One day it would start fine and run smooth, now this. Now takes forever to start.
Does anyone know what causes this, thought of something to do with the injectors or fuel filter, evidently the fuel pump works fine.
Cheers for any help
-
There are 2 fuel pumps. Main 1 under car and lift pump in the tank. Could be either but id replace the lift pump 1st. Could also be a blocked filter but unlikely as this would be a progressive fault and not a sudden issue. Get a garage to check your fuel pressure 1st.

Replace the blue temp sender from VW, mine did the same! Fine one day then overnight wouldn't start without alot of effort. Best £13 I've ever spent :)
-
Changed the blue temp senser about a month ago. Not sure if it's VAG though, although the place I got it from has always given me decent quality parts. Could it be the wiring connected to it? My temp guage doesn't work sometimes, I changed that at the same time (it didn't work at all before).
It's now at the garage getting a running test. Will find out tomorrow what needs doing.
-
Have spoken to the garage and they want 200 to fit a new airflow meter. Too much. Does anyone know where I can get one from or does anyone have one going? Please respond, I can't live without my car!
-
Get yourself down to VW and buy a genuine blue temp sender. If it doesn't fix it keep it as a spare or sell it on :)
-
Ebay or a decent vw breakers for the £200 bit, worth a try.. First though change that blue sensor again as a couple of people had problems with non VAG replacements a little while back. Mine was a GSF one and gave up the ghost after about 8 weeks of being fited, changed lots of bits before i put a VAG sensor in on the off chance and it worked perfectly!! Ooohh i was annoyed... :grin:

Been there, done that :grin:

Have been on the phone to awesome and they have a new one for £95, should be here Monday. You have a point about the temp senser though, £13 isn't that much. Does anyone know how you can test it?
-
No point testing it, just get it replaced :)
Even broken ones can give you roughly accurate resistance values, thats the trouble!
-
He's right...... but if you do want to check it you need a multimeter and the chart (Fig 7-7) on this link - http://volkswagen.msk.ru/vw_doc/eva2/FU01/ch7.2.1.html (http://volkswagen.msk.ru/vw_doc/eva2/FU01/ch7.2.1.html)
The biggest problem is guestimating the temp of the coolant, easiest is to get the resistance, cross reference it against the chart and see if it looks like a realistic temp for your coolant to be. My ohm reading was 96000, considering the chart only goes up to 7000 i guessed something was wrong! :laugh:
Or stick a thermometer in your coolant bottle?! :wink:

anyone got the part number for this blue sensor for the kjet 16v cos my vw centre reckon they don't know which sensor it is. there bloody useless they even said the weighted shift rod off a mk3 wont go straight on a mk2 without major modification lol. nobheads but i need a number so if anyone can help ill be happy cheere
-
There isn't one for a 16v, only the digifants have em :)
The 16v does have 3 identical sensors in the right side of the head for the temp gauge, wur and 5th injector I think?
-
any idea what the part number is for them sensors? cheers
-
I think the one you need is 049 919 501, its a single pin black one :)
-
thx

Just got a new airflow meter through the post today, will be fitting it at lunchtime. Looks pretty straightforward but just wanted to ask if anyone knows of things to look out for when doing it. Any tips gratefully received.
-
dead simple, remove the vacuum pipes on the side, undo the clips, and unscrew the jubilee clip holding the intake pipe on. Wiggle it out, then the AFM is held to the airbox with 4 bolts. Don't loose the o'ring, and refitting is the reverse of removal.
Obviuosly you'll need to re-setup the idle & CO after:

Atfer fitting a new airflow meter, found out it was the temp sender after all. So I now have a spare airflow meter after the garage got the problem wrong (glad they didn't get my money!). Does anyone know how to see if an airflow meter is working properly, and also where to get VAG blue and black temp senders. I'm guessing VW but they're usually expensive.
-
Yes matey get your blue temp sensor from VW (think it's about £13). I can't get you the part number, I don't have ETKA on this machine, but I'm sure someone will have it. You can buy a copy sensor from GSF, but don't, it's crap and will fail.
-
Blue sender is 025 906 041 A, VW will tell you its only for models fitted with a catalyst, but it is defo the right one :)
You can get the black sender from VW as well, but it costs £20! Its only for the dash gauge though, so unless that has stopped working you dont need to replace it :)
