Intermittent P0403 Code - EGR

Hi all,

So I have now had the Engine Management Light (EML) come on twice, showing code P0403 when read. This has happened at the end of a long journey (Around 150 miles). In both cases, the light has turned itself off and no loss in power was felt but I am wondering whether it is best practice to clean the EGR and potentially change the control solenoid so that this does not happen again.

The car has been driven 130 miles a day for 9 months before and now does around 50 miles a day, of which these drives are all at 70mph on the Motorway. The car is also a diesel, was made in 2007 and has covered 178,000 miles so far. So I think the code popping up, could probably be fixed with a good clean of the EGR.

If anyone has had any experience with either removing the EGR valve or with this code before, then I would be interested in hearing how you have fixed this problem.

Hondas have issues with EGR due to the solenoid and passages in the head getting clogged, I'd assume that's your issue as well. Do a youtube search on how to clean an EGR valve.
