It needs plugging into tech II to see what the Rail Oil Presssure Control valve is reading and the rail oil pressure sensor is showing .Both of these affect the starting and running .
The slow volts rise is just a lazy alternator.

Get it back to whomever did the job. Or maybe take it to someone who knows what they're doing. Turbo line is obviously leaking. If it's not cranking even with a jump you may have seized he engine. 2.7's are not cheap!

Golf tdi 1.9 2002 , 296000kms. turbi fitted 8 months ago. now takes long to pick up speed but on flats is better. not enough power


installing a new turbo on a vehicle can cause increased "turbo lag" in the system as the new turbo is not tuned exactly right, or worn in the same as the engine. If you take your vehicle to a mechanic and ask him to tune your turbo you might find some relief (with many turbos this is possible, but not all). This is a delicate procedure and should be completed by a professional (tuning the turbo for the car includes setting the exact pressure increase in the engine -- especially with a diesel engine, over-pressurizing the system can cause the engine to fire improperly and cause massive damage). A mechanic will also be able to tell you if there is something else wrong with the vehicle (like a clogged fuel filter, weak fuel pump or something similar) that could be causing the problem.

I have a 1988 Mazda Rx-7 non-turbo and not all the time but every now and then when i go to start it it cranks but wont start. Is the engine flooding or is it something else?


I always start my '88 RX7 with a 2 start procedure. First start is short about 3 engine revs...second time it always starts.
If I don't do that it cranks & cranks.....try it.

Hello.I got my Volvo s40 2002.Its suppost to have a turbo build-in.But I cannot feel the difference,basically when is turbo starts working?Thanks!


The S 40 came with different size and spec engines and they were not all Turbo charged versions. The choice of engines available depends on which country you are in.

The turbocharger is driven by the engine's exhaust system and runs continuously but has minimal affect at low engine RPM. Unless the turbo has failed, you should feel the turbo effect kick in when you accelerate hard but there will be a brief lag .

If you have the turbo engine fitted to your 2002 model S40 you will have a " 1.9T " badge on the rear of your car under the S40 badge. The "T" designates Turbo. An engine designator badge without a "T" indicates it is not turbocharged.

The turbochargers on these S40 models will fail (especially if the car has done a lot of miles) so you should have your car examined if you feel the turbo is not functioning.

Very slow in responce to excelerator


How about checking up your clutch plates & it's springs, which might be getting jammed & when released it engages the transmission resulting in wheels spinning & sudden acceleration. If the throtle is not opened up while taking off, the engine might & would switch off!....sodeep

Engine will not crank intermitantly


Crank sensor can translate heat. Not allowing restart after the turbo heat radiates in the area. Try a wad of aluminum foil in front of the crank sensor(on the block behind the turbo) . It protects it from heat and its a cheep test. If this works you can make a better sheild or leave the foil.
