Is this the fault ?

Is this what is causing the problem for the air intake sensor to flag up on VCDS ?



This little cone has been plugged in the induction kit for over a year, and it didnt cause no problems, its just after the car had been parked up for a couple of months, the juddering started and the turning off it self problem. i changed the HT leads, dissy cap, and rotar arm and spark plugs. and put another maf on it, but still flags  up with intake sensor issue.

today it cut off once whilst i was doing 40mph and braking to stop at a set of lights, and when i start it, it needs a bit of a rev hold to keep it on. but usually when i turn the car on after its been parked, it starts perfect, its just when after its cut out, it struggles for a second or 2 to start.

Like i've said m8,can't see what purpose that little filter would serve.Where that little filter has been fitted should be you air intake temperature sensor,which will tell the ECU how cold or warm the outside air temperature is thus enabling it to provide the cylinders with more or less fuel.

cheers for that ill have to get hold of a sensor, bit dear tho im sure there around £30 odd

Sensor will only be any good if you have the wiring to connect to it.Not sure what the previous owner did with the air intake sensor wire but it must have been there originally.

The wiring is there, i pulled it out today, it was stuck in the arch..... but what i dont understand is why isit turning off after a year of not having the sensor ??

Maybe that it has another problem that isn't being recognised by VAGCOM.Sometimes a faulty Crank Sensor will not be found by VAGCOM.When the car cuts out does the oil light flash at all.?

Itteh, take the bloody filter off, there useless on anycar let alone an 8v! get a standard air box for the thing, unplug all your connectors, give them all a dam good clean, have you tried getting a new battery?? Jus because it might be reading 12v and your alt is putting out 13v doesn't mean it's all good. The battery could have a dropped a cell over winter and then when under load may just be giving out, I'm betting you have a nice big sub in there too that will be kicking the ass out of the battery that your little 8v alt can't keep up with. Your doing the worst possible thing which is diagnosing through replacement, and it's the wrong way to do things, you could have ruled out your dizzy, rotor arm and lead simply by checking for a strong consistent spark at the end of the leads, or better yet you could have unplugged them one by one and stuck another spark plug in them and checked for a consistent spark thus ruling out everything you've replaced, my father in laws car kept cutting out mid driving no matter how far or short of a journey he went, no matter what speed he was doing, wouldn't even turn over sometime even after driving 20-30 miles, new battery and it hasn't done it in over 2 months now.

lol redders my original was in mr scottish's red 8v that got written off, its the mechs around here they all have a mind of their own.... i aint got subs or anything in car, iv only got rear door card speakers working at moment... i took everything out of it was i was going to sell but changed my mind. im trana get hold of standard air box, your still livin in livvy seeen ur VR parked up seen ur pop's car too .... only if you had time to check it, rather pay u than pay tom dick & harry around here,

Put it back to standard or at least lose the breather filter and reinstall the air temp sensor.

If one filter is not giving enough power that two filters will 


I have a mint airbox here will a newish genuine MAF fitted, yours for a good price?
