Its the position sensor. Need a new TB

ASY engine

Good day all. Have a strange noise coming from the throttle body on my mk1 1.9 fabia diesel. It buzzes for approximately four seconds when the ignition key is turned on and continues to buzz for four seconds, then off for four seconds, then on again four seconds all the time the ignition is on. No hit on performance, no warning lights, nuffink! Just this buzzing from the throttle body which you can feel if you put your hand on it. Any ideas please? Tank you

Yes they are. Took a photo anyway. Just in case

I had better get the thing out then quickish... 😃

Worth more than that! You undersell yourself sir! I shall remove the whole unit then and pack it to send. How do I get the money to you?

Would you be willing to do that? That would be fantastic! Should I get the relay first, just found a few on ebay. Right numbers apart from the very bottom one which starts with ++. Just name your price! It will be worth it for peace of mind.

Hi again. I did as you said just now, wipers run linked like that and i tested that with pins 3&4 and pins 3&5. Both speeds work fine. So that rules out a wiring fault and confirms that the bcm is faulty. (This was with that plug right out of its socket as well) I am having trouble finding a second hand bcm for my ASY engine code and may need to perform surgery on the nasty board as you suggested. I hate having to bogger around with solder but it seems i may be forced to. I have the desoldering tool thats like a small chicken basting bulb. In fact it's very useful for basting blackbirds when you bake them in a pie.(as the rhyme goes!) One thing that is making me hesitant is doing the job and STILL having that fault! Would be just my luck! Needs must, and all that.

Hey! I could jury rig the wipers full time that way! 😃 Just kidding! Thank you muchly.

Going to shove 12volts up pin 5 later to see if it jumps in to life

I did consider the soldering option but chucked that idea out as I have so much other work on, it's not viable. Ta. I have had the board out, the relay itself seems to be quite fine with its clicketty click, but is very erratic. Sometimes it clicks in all positions and sometimes only in speed two. I noticed that sometimes tapping the board made the wipers momentarily operate but then nothing. Also there's another relay on the board which clicks in and out at random. Im thinking it may be a dry joint somewhere on that board. I can pick up a second user module for a tenner with a new relay already in from a polo (same part number) so will just need to get it cloned. £80 and its back on the road! (I won't be paying for it anyway, my daughter will!)

Thank you Pete! You are a shining star!

Morning! Does anybody know which connectors run to the front wiper motor on the bcm? Got no power at the wiper motor plug so i need to test the line out from the bcm to motor. Am I right in thinking that its the second black plug with four pinouts? Thankyou
