Most Bmw models seem to suffer from form turbo Diesel problems at some point,
the problem seems to range from the Bmw 320d to the Bmw 330d ,,
Bmw X5 and also the smaller Bmw X3.
The main cause of Bmw turbo failure is the condition of the engine oil.
A diesel engine will produce a lot of soot type gases which make there way into the oil via the piston rings in the engine.
Theses gases are vented back into the engines induction system via the crankcase breathing system, so in theory they never stay in the crankcase long enough to contaminate the oil.
But unforantley this process occurs constantly when the engine is running and eventually engine oil gets contaminated to the point where it can no longer lubricate the turbo.
Once this happens then the bearings in the turbo. start breaking apart which causes the compressor blades to spin of center,
this will cause turbo whistle on your Bmw 520d or 120d andeventulay break appart.
Bmw 520d and Bmw 120d suffer from turbo whistle along with the Bmw X5 and X6
Bmw engines have a crankcase breather filter which is located on the top of the engines rocker cover, this filter allows the crankcase gases to flow into the induction system. A common problem with the Bmw turbo breather filrter is they can block up and cause a build up of crankcase pressure to exit through the turbo, once this happens then its only a mater of time before the turbo on your Bmw will fail.
The Ford Focus C max tdci is fitted with a 16 HDI engine, this engine suffers badly from turbo problems and has a serious oil sludging problem. When you combine this with poor servicing then you cause an oil circulation problem, this is the main cause of turbo failure on the Ford Focus tdci. A vehicle turbo needs a constant oil supply at engine oil pressure to keep the bearings in the turbo lubricated, the oil must also get through the turbo and circulate back round the engine. If the oil supply to the turbo is interrupted for any time then the bearings in the turbo will fail and the turbo will shake it self to bits. Replacing the turbo is simply not enough on the Ford Focus 1.6 tdci, the only way out of this problem is by doing the following.
Remove oil sump from bottom of engine, wash it out and thoroughly dry it, replace the main oil pick up pipe which bolts onto the bottom of the oil pump, there is a wire mesh type filter inside the pick up pipe which can get blocked very easily, remove and clean out the oil filter housing, refit it and fit a new oil filter, refit the sump. Replace the oil feed pipes and oil return pipes going to the turbo as they are probably blocked up with gunge, remove all breather pipes and clean them out, replace all crankcase breather filters, they are normally on top of the rocker cover or on the air box. Carry out a Dpf removal and Blank offthe EGR valve (see dfp removal videos ), now fit the new or reconditioned turbo. Once its all back together fill the engine with new oil start it up and run it at idle for 20 mins, then take it for a drive until the smoke clears, here is a link to a video which describes the procedure well.
Peugeot 308, 3008, 407 1.6 hdi all suffer badly from turbo failure as its the same 1.6 HDI engine which is fitted the the Ford Focud 1.6 TDCI, although it is a Peugeot engine, which was used by different vehicle manufacturers for about 1o years or more, when you fit the same engine to different vehicles then you get the same problems. The Peugeot 308, 3008, is no different, they all suffer from the oil sludging problem which is the cause of turbo failure on the Peugeot 308 or 3008, Peugeot just describe it differently on your dash display, depollution system fault. There is a remady but it invloves the following.

Mazda 6 or Mazda CX5 Skyactiv dieselis fitted with a twin turbos ,this means there is normally a small turbo then a bigger turbo which work in tandem with each other to eliminate turbolag on acceleration. The difference in performance in the Mazda 6 or Mazda CX5 Skyactiv twin turbo is very noticeable but it comes at a price.
The Mazda 6 and Mazda CX5 Skyactiv twin turbo is also fitted with an advanced Dpf emissions system which reduces the harmfull soot levels in the exiting out the exhaust so to reduce its carbon foot print, this all sounds lovely but its how system works is what can cause Mazda 6 or Mazda CX5 turbo failure.
The dpf filter is inside the actual exhaust and is where the harmful soot particles are stored but at some point the particles are going to build up which means they need to be burnt so the Mazda 6 and Mazda CX5 preform a Dpf regeneration. The Mazda 6 and Mazda CX5 twin turbo Dpf regeneration involves the vehicles computer adjusting how it burns the air and fule mix to create a hotter exhaust gas which in theory burns off the soot stored in the Dpf filter. While your Mazda 6 or Mazda CX5 twin turbo is performing the Dpf regeneration mode it is also producing harmful gases to your engine oil which will reduce the engine oil lubrication properties and begin to damage the twin turbos.
Symptoms of Mazda 6 or Mazda CX5 turbo failure are reduced performance and turbo lag, turbo lag is where you accelerate but there is a noticeable delay before the power comes in, this is the first sign of one of the twin turbos failing. Other symptoms of Mazda 6 or Mazda CX5 turbo failure would a burning smell from the engine bay or excessive smoke from the exhaust, it all points towards one of or both of the twin turbos on your Mazda 6 or Mazda CX5 Skyactiv failing.
Volvo C30 1.6 turbo problems is related to the same 1.6 engine which is fitted to the Ford Focus 1.6 TDCI. Lord knows what Volvo where think when they decided to use that engine in the Volvo C30 1.6 diesel but its there and it has the same turbo problems as the Ford and the Peugeot.
Volvo and other vehicle manufactures do this from time to time, they out source a different engine for a particular model rather than use there own Volvo engine which is used in the Volvo XC90 is a much more superior engine, but the Volvo XC90 dose have its share forturbo failure.
The engine used in theVolvo C30 Turbo suffures from an oil sludging problem which will reduce the flow of oil to the turbo on the Volvo C30 Turbo, this reduced oil flow to the turbo will slow the turbo down which will result in a lack of performance and in some cases the turbo on the Volvo C30 Turbo will start to whistle. Turbo whistle on the Volvo C30 Turbo is cuased by the blades inside the turbo breaking appart which then changed the flow air coming from the turbo and cuases turbo whistle. There is a remady for Turbo failure on the Volvo C30 and it is as follows.
Remove oil sump from bottom of engine, wash it out and thoroughly dry it, replace the main oil pick up pipe which bolts onto the bottom of the oil pump, there is a wire mesh type filter inside the pick up pipe which can get blocked very easily, remove and clean out the oil filter housing, refit it and fit a new oil filter, refit the sump.

Carry out a Dpf removal and Blank offthe EGR valve (see dfp removal videos ), now fit the new or reconditioned turbo. Once its all back together fill the engine with new oil start it up and run it at idle for 20 mins, then take it for a drive until the smoke clears.
Bmw Mini turbo or Mini One Turbo diesel use a 1.6 diesel engine which is also used in the Ford Focus, Volvo C30 and most of the Peugeot Range. Bmw and other manufacturers seem to manufacturer one engine which fits all for there most popular or mid range vehicle and in this case its that same 1.6 Peugeot engine which is fitted to the Bmw Mini One Turbo.
Bmw Mini turbo is fitted with a 1.6 diesel engine which suffer badly from an oil circulation problem, this is caused by the dpf filter trying to clean itself. The Bmw Mini turbo will trigger what is called a dpf regeneration cycle which switches the Bmw Mini turbo engine mode to a more aggressive opporation mode to clean the dpf filter, this all sound very clever but there is a problem this self cleaning cycle.
Once the Bmw Mini turbo is in the dpf regeneration mode the engine oil is getting contaminated with harmful fumes which destroy the engine oil lubrication properties and will lead to turbo failure turbo failure on the Bmw Mini turbo. The first sign of turbo< failure on the Bmw Mini turbo is a drop in performance and can also be followed by turbo whistle. Turbo whistle is where the blades inside the turbo start to break apart which then disturbs the flow of air coming from the turbo and eventually lead to complete turbo failure on the Bmw Mini turbo, luckily there is a remaday.

VW Skoda Audi 1.9 and 2.0 Litre TDI seem to very sensitive to limp mode. Limp mode seems to be coded into the ECU and can not be removed, o the only conclusion is to fix the cause of your limp mode problem. VW Skoda and Audi tdi Limp mode is like a safety device which controls the amount of power the engine will produce, this is normally activated if the ECU detects an over boost of pressure from the turbo. The turbo is driven by the exhaust gases which pass through variable vanes then out the exhaust, the other side of the turbo compresses the air being drawn in by the induction of the engine via the compressor blades and into the engine. Once the induction pressure in the inlet manifold reaches a certain pressure which is detected by the map sensor, the ECU will start controlling the amount the variable vanes are opened via a vacuum actuator. Variable vanes act as a waste gate to control the amount of exhaust gas spinning the turbo, when the vanes are open the turbo will spin fully which will allow the turbo to reach maximum boost pressure, once this is achieved the ECU will close the vanes slightly to reduce the amount of boost from the compressor side of the turbo.
For the variable vanes to experience full range of movement the engine must experience the full rev range for the turbo to boost fully there for allowing the variable vanes to close for a few seconds, to achieve this you must drive your car aggressively making the turbo work hard, this should be done once per week. If you never do this then the variable vanes will start to stick due to a build up of exhaust carbon in one place because the variable vanes have not experienced the full range of movement.
Once the variable vanes stick on your VW Skoda or Audi tdi then they can not close when the pressure in the inlet manifold reaches maximum boost pressure, the ECU will detect an over boost from the turbo and limp mode is activated. The cause of the variable vanes sticking is a build up of exhaust carbon between each vane, the only way to free them is to remove the turbo and send to a turbo repair specialist who will strip the turbo down and replace the variable vanes, and it is always a good idea to give the turbo an overhaul while its removed from the vehicle.
