My case was 100% the same as Briscoe76 and I`d like to thank him for this post, very detailed and helpful.
So I followed the instructions on the post, purchased the resistor and did the procedure.
The lightning bolt has gone "aleluia" , however, the Engine light remains On all the time, the car is running smooth, I took it at 160Km/h and it's fine.
Any idea on why is that light still on??
My engine light was still on as well. Fixed it! This video saved me a lot of hassle. https://www.youtube....h?v=kZeniXP9o4Y I remembered the advice in the video about the air-pipe-to-turbo o-Ring. I revisited it and found that I'd nipped it, hence the turbo wasn't working properly, hence it was a bit rough and the check engine light would not turn off. This was lucky though, because I'd followed the advice to "Replace the metal bracket, and the air intake pipe, leaving the plug sticking up so you can get to it again in the future if you need to." So I had indeed left it sticking up. I'd then driven 10 miles after the fix. When I popped the bonnet to check the turbo o-ring I noticed my nice new emulator had started melting into a gooey black plastic mass! Fortunately, it was only the end of it, no damage done to the innards. I've now tucked it back down in the vee. Those few inches in height obviously make a lot of difference temperature-wise under the engine cover. Otherwise the advice is perfect so please don't think I'm bitching about it!
