1.4 16v 2001 Polo engine AUA.

ECU Amber check light came on and the went off again. The car runs OK but under load apppears to struggle like an igition fault.

I plugged in a Fault Code reader and the only Code is 17604. Which I think is O2 sensor. I erased the code.

Been on lots of 10 miles plus drives. ECU light stays off with no codes. Went on a short trip to get a tyre. ECU light back on.

Just bought a Bosch 5 wire Lambda sensor from the motor factors, which they say is was the correct one and fitted it.

Now, straight away the Engine light comes on. Read the codes. Now I have 3.

All lambda related. The car ran fine.

Do I need to program the ECU which this new sensor or should it work without.

I put the old sensor back in, erased the codes. ECU light now 'off' back to square one.

Anyone out there with some advice please?
