astra J code 55 by Englishkeymaster » Tue Oct 02, 2018 4:59 pm Just a quick one re 1.7cdti denso - SH7059 - this code (which illuminates on dash) insinuates a dpf problem, in this case the user unknowingly bought a car with it gutted and constantly regenerating. #3 · Nov 5, 2017 I've just agreed to purchase a 63 plate Astra 1.7CDTi 109 and when I was out on the test drive I noticed a code 55 error code on the dash, and the regen light was on. At the time I thought the light meant that the washer fluid was empty! fsTYNHz.
