Sealey OBDII Code Reader not working?

I have just got myself one of these new

thinking I could use it to clear my engine light that I get every now and then from the lambda sensor...

I can plug it in and read the codes (there's 2, one for lambda and one for some random missfire it did for 2 mins a couple of months ago).

I can then get it to erase the codes, it say's it has erased codes successfully or similar. However I can still view the codes on the reader.

I have then tried 2 different things after this stage.

1) Turn off ignition and unplug scanner - turn on engine and no success

2) On the reader you can select rescan. Which it then does and tells me there are no fault codes and I think it says the MIL > OFF (I don't know if that's the engine management light)

However, when I turn off ignition, remove scanner and turn on the engine the light is still on. If I then turn off the engine, connect the reader back up it gives me the same 2 codes, and I end up going round in circles.

Any ideas? Anyone else used these scanners successfully?

Car is an 03 plate VTS.

Cheers

Just a pure guess after you`ve erased the codes unplug the battery for 1/2 an hour then see what happens.

Have you checked the lambda and knock sensor could be faulty or actually sensing a 'fault'?
