Where are you guys getting your replacement 4.9s from? I think mine has had enough after some rich running and tuning sessions!

amazon sell a replacement


I went directly to PLX to buy my first replacement and when it showed up it had the same markings and serial numbers as the sensor above.

Looks to same as my polo 6n2 that one is 19yrs old
70 obo on egay

a genuine Bosch will be c£80 upwards

there are cheap copies out there. i wouldnt bother when you are talking a safeguard part for a motor that will cost £3k plus to replace if you det

boosted cars seem to eat these but they are 20 mins to swap if you have to jack up your car twice..

hey Noodels, i'm not sure an o2 from a polo is gonna help us.

wideband sensors give an accurate AFR across a broad temp spread so are useful in modified and boosted applications but dont last well in the former.due to rich running, sooting up, poor cold start management, higher egt etc as per that link i posted.

i dont think that part number is relevant?

a stock o2 is cheaper and more durable i think

The amazon link i sent is identical to the one currently fitted on my car. Its definitely a wideband sensor.

Agree part numbers are not relevant ,just saying its listed in the sensor fitment <with a pinch of salt>
