curryinahurry 39 Report post Posted December 17, 2017 So I've recently picked up a E46 330d to drive around the country over the summer. The car has a thorough service history from BMW, so I really wasn't expecting to do much - but the service book doesn't mention whether its had the swirl flaps removed. So I thought I better check by removing the manifold. Couple of hours later - heres what I've found : The swirl flaps are still there - 1 barely!!! The shaft had snapped, but the flap itself is still lodged in there - Very lucky!!! Given its only 1 more week til xmas, I really needed to get this sorted. So I spent the next day making swirl flap blanks. While I was at it, I gave the EGR a clean too! Got it all back together this afternoon and took it for spin. All is good Currently I'm getting around 8.7 L / 100 km, its quite a bit higher than my mates tuned 320d - he gets 900+ km in a tank. Does anyone know whether mines running normal? It sits in traffic most of the time... Andrew 5 Quote Share this post Link to post Share on other sites
Olaf 3321 Report post Posted December 17, 2017 you made your own swirls flap blanks! Awesome. top marks I'd guess that 8.7l/100km in traffic isn't too bad. it's when you get onto a trip that you can expect to see that fuel economy the diesel lump is famous for.

allan 295 Report post Posted December 20, 2017 Brilliant save, boy the cash register would have been ringing on that if it went the other way. By chance where those deposits dry or oily?. Even under city driving thought you would have gotten better economy than 8.7 plus the ruc would make as bad if not worse than petrol. Still be interesting to see what you get on a long trip. Best of luck have a safe holiday. 1 Quote Share this post Link to post Share on other sites
kiwi535 538 Report post Posted December 20, 2017 my 120d(manual and chippped) was always 6.5 l 100 k around town,but i never really sat in traffic much.Open road was 5,5 l 100 easy......if you were always on the flat i reckon it would be in the 4 s.... the 120d was high geared 100k in 6th was about 1700 rpm almost of boost 1 Quote Share this post Link to post Share on other sites

The deposits definitely wasn't bone dry, but not quite dripping with oil either. What are your thoughts? Quote Share this post Link to post Share on other sites
allan 295 Report post Posted December 21, 2017 Not sure If oily were did it come from / or normal the first thing that comes to mind was turbo seals beginning to leak then a ccv system gummed up but could be being an alarmist. It may have a good service history but it doesn't tell you the type of driving the vehicle had how many ks if you don't mind. Quote Share this post Link to post Share on other sites
kiwi535 538 Report post Posted December 21, 2017 the egr circulation system will always be slightly oily/damp so you end up with damp carbon depsoits in the inley manifold Quote Share this post Link to post Share on other sites
E30 325i Rag-Top 2959 Report post Posted January 7, 2018 Deposits are usually from the CCV system in these engines, especially on higher km engines. Check the filter in the CCV has been changed. Quote Share this post Link to post Share on other sites
