really, as the title says. i was under the impression i had a PD engine, but i have a friend who is arguing tooth and nail iam in a common rail engined golf, he says only the 130 & 150 bhp models introduced later were the PD engines? can anyone clear this up for me?
There are NO common rail engineered VW passenger vehicles
Heres a nice gentle read....

:confused: ok im confused now! Rick, whats that artical all about? im confuggled :S
and by the way, it is a mk4 2000 w plate
High Pressure Injection - NOT Common Rail
Pumpe Düse - which means ‘pump injector’ - overcomes the problem of pressure lost through fuel pipes. The injector and pump are integrated into a single Pumpe Düse unit. Each cylinder has its own Pumpe Düse unit mounted in the cylinder head and operated by the camshaft, injecting fuel
directly into the combustion chamber at pressures up to 30,000psi.
These high pressures produce a far more efficient blending of the fuel/air mix, precise control of fuel quantities and injection timings.
ok, :d thanks for clearing that up! 'tis a rather confusing subject matter for those of us who are still learning! i'm currently researching the new phase of common rail as ihave been told, this is going to leave PD engines standing as far as economy is concerned?
sorry ESHRULES...
i should of expalined a little more... as per VW Techniker
however after that read at least you know more about a common rail engine i guess....
Cheers

Just thinking..... LOL.... there nothing like been throw in at the deep end... and thats just a basic overview....

errrrrrrrrm..........
just to add fuel to the fire.
When trying to source a replacement head for my 150 GT Tdi PD Golf, the suppliers were insisting it's part of the common rail family ??????
Didn't argue with then, just wanted a replacement head :rolleyes:
Cheers
LOL well my 'friend' had told me that anything less than 130 bhp was a common rail, ie the older diesel engine, less economical than the current PD etc etc, but that theory seems to have been thrown straight out the window LOL. im gunna do some reading up me thinks, its so easy to get confused with misleading info :confused: LOL
Its basic principles are common rail... I suppose, in that all the injectors are supplied fuel by the same fuel pipe, but, its operation is quite different.Quote:
