Codes P1571 & C1446

Andy, I think I will take your advice and ignore it. When it goes in for a major service next year, I will get the garage to check it out.

If you're not sure exactly when these codes may have appeared and have no message on the dash, it could be that they are the leftover evidence of a suspension problem from earlier years when the problem was solved, but the codes were not deleted.
When driving, can you detect the difference as the suspension operates in different driving scenarios?

[DougX]

Astro, To be honest, my diagnostic reader is able to delete codes, but for what ever reason, it is not doing it. As far as noticing a difference as driving, to be honest, I can't tell any difference.

If the problem was current then I am sure you would get a message in the message centre.
