MAF sensor for Jetta 4 TDI

[dirkme]

Hi,

I suspect my MAF sensor on my Jetta 4 TDI is not working properly. When I am travelling and suddenly press the gas pedal it takes a long time to accelerate, it used to be quick. Also my fuel consumption seems to be slightly worse than normal.
Last one I put in was a reconditioned unit, installed it about 3 or 4 years ago.
Any idea where I can find a MAF sensor new for a good price in Pretoria/JHB area?
Thanks

You can get a bosch unit from goldwagen for about R1200

Unplug ad see if it feels better.
check diesel electric too, they are always cheaper than goldwagen.

im too in this same boat,except im driving a 1.6. i tried unplugging my maf but the car wouldnt even want to move a 100m

[FM1]

so im not sure if my maf is broken or if its an airleak somewhere. maybe check your hoses if theres any air escaping

yup its a bosch unit. nuber for the pretoria branch (012) 327 4810

Maf on the tdi is basically there for the smoke control, if it reads low then it will limit fuel and thus decrease performance. when you unplug it it defalts to a certain value so performance is unaffected. thats why i said unplug it and see if it runs better.

on the 1.6 you have no wideband so unpluging it would undoubtably make the car run like crap.

R300 cheaper at goldwagen

I drove home with the maf unplugged. No change in power, slightly worse fuel consumption. There was no error given on the dash. Is that correct?

That correct yes. It wont give a error on the dash.
Have the car scanned to double check what the fault may be.

If theres no change in power then its the maf

Cool, one more question, should i clean the intercooler to prevent more oil from spoiling it? Car has just under 290 000 km on it.

[carapau]

theres oil spoiling ?


MAF sensor and cooler have nothing to do with each other ,but its always good to have the cooler nice and clean

[Killerwatt]

If theres no change in power then its the maf

I disagree with this, if there is no change then how can it be the maf?

[carapau]

coz when u unplug the maf the car goes flat

[Killerwatt]

okay then, thought it was the other way around with the tdi's...

[Tdi jetta 4 ever]

Correction. When my MAF packed up the car was dead up to about 2500 rpm then suddenly the turbo kicked in for a short while. When i unplugged the MAF the car pulled way better and more like it supposed to be. But MAF's also give different symptoms when they pack up.

[Killerwatt]

thats how i knew it...
