You need to see what the actual value is in measuring blocks, does the code clear and then come straight back or does it take a while?

When I clear the code I drive a mile or so then switch engine off then when i start it up about 5 seconds later lights back on

Does your code reader show measuring blocks?

No I dont think so I used an obd plug which works with phone, was the same fault code at the garage I went to, how do I test measuring blocks will look into it

You need a diagnostic system system that will show the data.
