Faults 1900 + 1109 after cleaning egr

[richieski]

Hi all, I have a 2006 93 150. 40k Thought i would do some preventative maintenance on it and clean the egr. It wasn't too dad, cleaned it all up and everything is free and moving. Alot of crud in the downpipe and manifold. 2 days later management light comes on. Got the fault codes read, 1900+1109 swirl flaps and exhaust gas sensors. Got it reset and ok for 2 days and light is back on. It runs fine no loss of power etc, i have the day off tomorrow and am pretty handy with most bits. Is there anything I can do / look for myself on the swirl flaps mechanism etc

Well just plugged in my obd and I have just P1900 didn't take note to see if it was 51 or 52. Cleared it again, would it be worth taking out for a good spin. It has only one 40k in 6 years and I have owned it for 3 weeks and travel many miles daily
