Jaguar 2.0 se diesel turbo power loss

Sounds like piston blow by, as the gap increases and diesels have such high compression. When the turbo kicks in, the pressure is restored.

Since the power generated by the turbo depends on the volume of combustion gas generated, look into your fuel delivery system. Your engine might not be receiving the required amount of fuel. Check your fuel pump, filter, injectors, and lines.

Some whine is not really a problem and is not worth the cost to replace the turbo. You have more than likely heard trucks with turbo whine and they don't worry about it. If the whine is really loud then the turbo has a worn bearing and it will need to be replaced in the near future or it will seize up eventually.

COULD HAVE BAD FUEL WRONG TYPE FUEL COULD NEED NEW AIR FILTER. DIESEL ENGINE NEEDS AIR TO OPERATE.IF AIR FILTER RESTRICTED.DIESEL ENGINE WONT RUN AND CLOGGED FUEL FILTER CAUSE STARTING PROBLEMS PROBLEMS WITH TURBOCHARGER OR TURBOCHARGER ACTUATOR WOULD CAUSE ENGINE RUN VERY SLOW NO POWER ON TAKE OFF.I SAY PROBLEM IN FUEL SYSTEM OR AIR INTAKE SYSTEM.IF YOU HAD ANY OTHER PROBLEMS THE CHECK ENGINE LIGHT WILL FLASH ON.

turbo problem

i had this problem and thought the fuel filter oil filter needed replacing so i have just had a service done but problem is still there but not as bad. been told it could be the AGR valve or a split pipe going to it which recuirculates unused fuel back to burn again. therefore unspent fuel is coming out of the exhaust causing the black smoke. i am still looking for the answer aswell, hope this helps.

Same problem on mine was a block fuel filter (quite common). About £70 fitted by main dealer. I'd stay away from whoever told you the above and get a second opinion!
