If you mixed diesel with air before it entered the cilinder and then compressed it in a normal ( Diesel engine ) compression stroke it would certainly detonate before you reached top dead centre. However in normal operation, diesel is sprayed into the cylinder and burns as it exits the injector and comes into contact with the heated air. Only the diesel ...

It isn't really important what kind of oil do you use for breaking in your engine, just use good engine oil. The most important thing is that during assembly all the parts got coated with engine oil.. If you are really concerned about the breaking in i would suggest you to use an external oil pump to fill the oil circulation system with engine oil before the ...

The VW diesel engine controls that I'm familiar with (ALH and BEW mostly) are drive-by-wire and the throttle position will be at 0% at idle. You may have a different controller, but I wouldn't expect the throttle position to be much different. The ECU is responsible for managing the idle speed and doesn't need throttle input to do that, hence the 0% (driver ...

How is the turbo pressure regulated in these cars? If there is a linkage that actuates the wastegate maybe it needs adjustment.

Not all Diesels are the same. My former car, a 1994 VW Passat 1.9 TDI had only one fuel pump in the engine bay. This pump was responsible for several things: bring fuel from the fuel tank raise the pressure to the injection pressure (approximately 600 bar) distribute pressured fuel to each injector in the correct order There was no electric pump to "...

Addition to dlu's answer. Look for restrictions in the intake and exhaust. You can try bypassing the intercooler. For the exhaust, you can temporarily set up an open pipe out of the turbo. either way, something is restricting the turbo from keeping up.

My first thought, based on the boost dropping as you rev the engine before the turbo was replaced is that there is an inlet restriction. Something like a dirty air filter or damaged inlet piping. That could also cause the replacement turbo to fail to deliver full boost. One quick check for this would be to remove the compressor inlet pipe from the ...

Look in the owners manual (if you don't have it, check online there may be a PDF version available). That should both tell you what the various reservoirs are for and what is supposed to go in them.

Diesel does damages rubber. Diesel fuel may cause stripping of certain types of rubber hose, gradually perforating the fuel hose. Thus, it is strongly advised to make sure if the fuel hose to be installed is rated for diesel. To clean a diesel spill, you first need to pour lots of warm water on the spill to instantly reduce the risk of rubber damage. Then ...
