Re: O2 Sensor

pretty much any 4 wire o2 sensor will do, go to a renault dealer or so... You'll need to solder the wires though

Re: O2 Sensor

doesn't have to be an alfa dealer for this, any parts supplier will be able to supply a 4 wire lambda probe, I would suggest avoiding the universal type without a plug on the end though as they tend to be very cheaply made and can be worse than the one you take off!

Re: O2 Sensor

I need to replace Lambda sensor.

Original BOSCH number is:

0 258 006 191
0 258 006 190
0 258 006 021

THE QUESTION IS: Will the BOSCH universal lambda numbered below fit instead of the original one?

0 258 986 506
0 258 986 507
0 258 986 504
0 258 986 502
0 258 986 505
0 258 986 602

156 (932)
2.5 V6 24V (932A1)

Re: O2 Sensor

they're all the same size on the exhaust end, but there could be differences in the heater element, and the leads for sure are different.
