I can&#8217;t stress this bit enough, there is PLENTY of room for it to fit. Whilst there&#8217;s room to probably rotate it, I fitted mine with the exhaust manifold going in sideways iirc. As long as you have the driveshaft out, just take your time and slowly guide it up and rotate as needed.

tips for replacing BKD turbocharger in the Audi A3<\/h3>\n<ul>\n<li>When refitting the Turbo fit the EGR cooler pipes AFTER (it gives access to two nuts &#8211; I had to use a 1\/4&#8243; Ratchet)<\/li>\n<li>Remove the little metal piece on the steering rack mount that holds the cable for the oil sensor, it will stop you scratching your hands<\/li>\n<li>Pre-fill the turbocharger (<strong>CRITICALLY IMPORTANT<\/strong> &#8211; not doing this can cause the Turbo to fail) &#8211;\u00a0<strong>DON&#8217;T SKIP THIS STEP; my turbo did seem to be prefilled already, but it&#8217;s not worth the hassle relying on it. All the guides I find recommended prefilling until oil runs out the top so I did this. You know it has it then.\u00a0<em>Also when pre-filling, you&#8217;re meant to turn the compressor blade (counter clockwise btw)<\/em><\/strong><\/li>\n<li>Loosen the driveshaft nut with the wheels on the floor if your impact gun sucks<\/li>\n<li>Find a way to organise screws (freezer bags, food bags, etc) &#8211; Make life easier to identify<\/li>\n<li>Remove the driveshaft, I&#8217;d say it&#8217;s impossible to get the Turbo replaced with it in<\/li>\n<li>Wear safety glasses, the amount of crap that falls in your ears and eyes is annoying<\/li>\n<li>The turbo clamp may be a tight fit after removing the nut, may need to chisel it loose using screwdriver<\/li>\n<li>Using a pry bar and locking into the tie rod \/ drop link you can hold it down, makes it easier to move hub<\/li>\n<li>Consider a magnetic tray underneath things when removing nuts, I lost a gasket and nuts because they fell<\/li>\n<li>Consider a pillow for your neck, it will ache if you don&#8217;t support it.<\/li>\n<li>Consider buying some copper washers \/ spare washers (if you&#8217;re using the Darkside Oil Kit), I lost one when fitting, had a spare. Also the Turbocharger mounting bracket was off centre slightly for me, so I increased it&#8217;s width with a washer to mount it again<\/li>\n<li>Remember to transfer parts, you will need to transfer hose clip on old turbo, and oulet pipe from old turbo<\/li>\n<li>The recommended time is to leave engine running for 5 mins and check for leaks, if OK, you should be good<\/li>\n<\/ul>\n<h5><a href=\"https:\/\/ebay.us\/5kQREW\" target=\"_blank\" rel=\"nofollow noopener\">Browse eBay to buy rebuild kits, new CHRA cores, new Turbos, or Turbo parts<\/a> [ AFFILIATE LINK &#8211; OPENS IN NEW WINDOW ]<\/h5>\n<h3>How much did this all cost to replace the BKD turbo on my Audi A3?<\/h3>\n<ol>\n<li><a title=\"Darkside Developments GT1749V Turbo\" href=\"https:\/\/www.darksidedevelopments.co.uk\/products\/garrett-gt1749v-bkd-pd140-2-0-tdi-turbocharger.html\">Turbo<\/a> (\u00a3630), <a title=\"Darkside Developments Oil Return Pipe\" href=\"https:\/\/www.darksidedevelopments.co.uk\/products\/oil-return-line-for-1-9-and-2-0-tdi.html\">Oil Return Pipe<\/a> (\u00a357), <a title=\"Darkside Developments Braided Oil Line\" href=\"https:\/\/www.darksidedevelopments.co.uk\/products\/darkside-braided-oil-feed-line-for-1-9-and-2-0-tdi.html\">Braided Oil Line<\/a> (\u00a360)<\/li>\n<li>Engine Oil (\u00a348.29), Oil Filter (\u00a34.58), Sump Plug (\u00a33.75) &#8211; Delivery fees \/ VAT ! &#8211; (\u00a317.32) &#8211;\u00a0<em><strong>From <a href=\"https:\/\/www.opieoils.co.uk\/\">Opieoils<\/a><\/strong><\/em><\/li>\n<\/ol>\n<p><strong>TOTAL : \u00a3823.94<\/strong><\/p>\n<p>These are the &#8220;essential&#8221; items I&#8217;d recommend buying if you&#8217;re doing the same route as me. I actually spent approx \u00a3150 more buying various connectors, hoses, etc. Some I used, some I didn&#8217;t. Maybe budget an extra \u00a3100 for necessary items. I&#8217;d also recommend making sure you have a supply of nuts, gaskets, etc. As you will need to replace all the gaskets you use.<\/p>\n<p>The Darkside kit comes with Exhaust Manifold Gasket, EGR Gasket, Oil Return Gasket, Exhaust Gasket<\/p>\n<p>Don&#8217;t bother buying parts from Audi \/ VW if you have to. They&#8217;re expensive. The Oil Return pipe is \u00a375, and doesn&#8217;t come with the Gasket, the Banjo fitting, or new screws. These are all seperate. The Banjo fitting is ~\u00a320 iirc, and they&#8217;re also special order, and the Screws \/ Gasket would be ~\u00a310. I purchased the OEM pipe from Darkside, and it came with screws and gasket. I bought a replacement Banjo fitting seperately, but ended up never using it. I retained the old one.<\/p>\n<p>I also didn&#8217;t buy the Turbo feed pipe from VW because it&#8217;s no doubt in the region of \u00a380 or \u00a390, plus whenever I use the Darkside kit, it&#8217;s resuable through the design. The VW pipe twists constantly and you need a new one each time. The Darkside kit has banjo fittings, and cheaper. Plus it also uses copper washers which can be replaced easily. If it&#8217;s good enough for their tuned cars, it&#8217;s good enough for my 140HP car.<\/p>\n<p>As a note, if you want to purchase a Banjo Fitting (<a href=\"https:\/\/audi.7zap.com\/en\/rdw\/audi+a3+s3+sportb+lim+qu\/a3\/2007-412\/1\/145-145055\/\"><strong>Part number N90916501 &#8211; 7A in this Diagram<\/strong><\/a>), you will either need to order directly from Audi \/ VW or search an alternative. I managed to find what looked like an <a href=\"https:\/\/www.deutsche-parts.co.uk\/n90837101-new-genuine-part.html\"><strong>alternative part number on Deutscheparts<\/strong><\/a> so purchased it as a chance as it was only \u00a37.78. I never fitted it, but kept it as a backup if needed<\/p>\n<p>As a note it&#8217;s sizes are A12XM18X1,5 which also fitted Forklift trucks, so you may be able to find one through suppliers here.<\/p>\n<p>&nbsp;<\/p>\n<h3>What else is left?<\/h3>\n<p>From driving I noticed two things<\/p>\n<ul>\n<li>The Turbo feels like it&#8217;s pulling hard from around 2500rpm. I&#8217;m assuming the Turbo is configured correctly as it was built my Garrett themselves, but I&#8217;ll need to log with VCDS to check this. Been a while so can&#8217;t remember how the cars drive and at what RPM they&#8217;re meant to kick in. Worst case I need to adjust the actuator rod, but I feel it&#8217;s working correctly. It could also be the pipework I&#8217;ve introduced. Either way, it drives.<\/li>\n<li>My car is still making black smoke on boost. Although I believe this is more down to old oil in the pipes \/ exhaust being cleared out when I drive. Eventually it will disappear. Also my EGR \/ Intake manifold need cleaning which doesn&#8217;t exactly help this. So when I get new gaskets I&#8217;ll be cleaing out the EGR and intake pipes a bit better.\u00a0<em><strong>Seems fine now, air filter wasn&#8217;t tight, and probably clearing out old oil in pipes from previous failure, a good horsing cleared out the engine. Also my EGR readiness is now &#8220;passed&#8221;, it used to be always Incomplete. I believe in order for it to pass, it has to be fully WOT in the gears 3rd or 4th<\/strong><\/em><\/li>\n<li>Gaskets, I need to replace them on the EGR system. I dropped one, and only had 1 spare. They&#8217;re fiddly as hell. They&#8217;re just little weekend jobs though.
