QuattroMark Posted July 16, 2017 Share Posted July 16, 2017 Hi Martin, My 2.0l BLB engine sounds exactly like yours - It didn't before the remap, started about 18 months ago - I didn't have my egr blanked off, but the remap has certainly affected it as the readings on VCDS are all over the place - I know you have had the EGR removed, but look at block 4 in group 3 under ENGINE in VCDS - is it at 100% all the time? And also, the cam lobes look fine to me - as for the timing, your torsion value is 0.5 so I cant see how your timing can be out - one thing that made a difference to mine was when I reset the backlash on the injectors after replacing one of them - I'm hopefully going to see a diesel specialist next week for him to try and figure out what is causing the noise - spoke to him over the phone and he seems quite confident !!!

QuattroMark Posted September 1, 2017 Share Posted September 1, 2017 Hi Martin, In short - yes it is sorted......but not in the way i hoped!!! I ended up refurbing all 4 injectors - I replaced the unit that was out of tolerance and it made no difference on its own, however after changing the other 3 ( what i thought were ok) injectors it was like a different car - there was still some 'noise' there but no where near as bad............it was then suggested that the EGR was replaced, I was a bit unsure about this as it was only changed 2 years ago after total failure.........again, the difference was incredible. The noise I have now is attributed to engine wear and the remap......I am considering getting it put back to stock.......just to see if it makes any difference. However, I t really is like a different car now, so i guess i may live the the slight noise!! Mark Quote Link to comment Share on other sites More sharing options...

Rob82DZL Posted September 1, 2017 Share Posted September 1, 2017 My old A4 115 (AJM Code I think!) was remapped to 150 and was way louder than yours. What I found was two very worn hydraulic lifters. One thing to look out for if you go down the route of whipping them out is to check the lining they run in, if the lining is overly worn you could be looking at a new head. I don't think it sounds like a timing issue! To be honest it doesn't sound bad at all. One other thing I remember is that you definitely get more noise once you remove the cat and egr, more noticeable with the egr removal. Hope this helps :) Quote Link to comment Share on other sites More sharing options...
