Hi all

I have today cleaned the EGR valve out as the engine was giving me a lot of black smoke and leaking oil from the join just above the EGR valve

I followed a very good article on here on how to do this - the valve was not too caked up BUT the Manifold? where it went into was. Where there should have been a hole between the top part and the bottom for the air to flow between was completely clogged so i cleaned all of this along with the valve etc put it all back together and now after about 5 seconds the limp home light comes ON

I now have hardly any power and am wondering what i have done to warrant this - the car ran better before i cleaned it!!!

I have put the valve back in correctly - it can only really go in one way reconnected the electric plug into the back of it etc nothing seems to be amiss but the limp home mode is on all the time - Before i take a match to it does anyone have any ideas?

I disconnected the battery whilst i did the job - took around 1.5 hrs and i did use quite a bit of WD40 around the valve to get it out - could that have caused a short somewhere?

Thanks for any help rec,d

ok thanks for that mate.

I have taken it all back off cleaned it again put it back on and wooosshhh the car was running brilliantly the only real difference was that i put the very thin flimsy metal brace thingy on between the two parts of the egr valve ( My egr valve actually came apart in two as i was tappin it to get it off and i had accidentally put the mettle brace inbetween the two bits if u get me!) and not next to the manifold as is should be.

When the egr valve came apart in two i have a feeling some of the WD40 i was spraying cud have actually gone into the solenoid itslef maybe this is causing an error code to be read and limp mode to come on....

Anyway all running mint until i restarted the car and the limp mode is back altho with a lot more power - i have now done around 50 miles since and its still on....

After stopping the engine and restarting it sometimes the light isnt on and it feels like a new car!!!!!

BUT eventually it comes back on

I will monitor the progress over the next few days and let you know how it goes thanks for the reply bud!
