A few weeks ago I bought via Ebay a Pierburg MAF sensor for my A4 TDi 110 as I had been told by the previous owner of my car it had received a new MAF sensor but he had lost the invoice......
Worried that it might have been a cheapo one I bought the Pierburg one as it even came with a little torx-style bit to be able to remove the sensor....something I didn't have before and so had been unable to get the old one out to see what make it was.
It turned out that the old sensor was a Bosch and the Pierburg went straight in with no problem.
This brings me to my question, with the new Pierburg sensor the engine really does seem much more flexible, before with the Bosch sensor the car would struggle to do 30mph in 5th gear without hunting, now in 5th at 30 the car is fine.....
Anyone else noticed a difference with different sensors? I don't think the Bosch sensor was faulty as it was only about 6 months old (supposedly) when I removed it, but the car does seem to run better with the Pierburg one......
