Code P0402.

[Old Peter]

Engine light came on again to day  ---  Too much exhaust gas going to EGR valve [or too little].

 

I went to Halfords in Lichfield to give the car a burst of speed and get some Wynns EGR cleaner. Having bought it with £1.50   discount, I drove back home and the warning light went off.  The threat of squirting some of that down the air intake must have made the valve afraid.
