pd 110 or not

[d1n93r]

is there any way of finding out if my leon is a pd engine or not. shes 04

 

[Seatmann]

Does it have a big fuel pump on the front? If not it's a PD. Also check the engine code, it should be on top of the timing belt cover, in the boot on a sticker or in the front page of the service hand book and read something like ALH, AGR, AJM, ARL etc.

She's asv for def. on what Side would the pump be

 

[Seatmann]

ASV is a non PD, the pump is right at the front and driven by the timing belt, looks a bit like this

That thing right next to the dipstick to the left in the pic, that's the pump.

Are you having problems or just curious?

 

[d1n93r]

No just wanted to know. Yea she looks like that. So what engine type is it then? Was just reading about egr deletes and puttin pd150 inlets on a 110. And wondered If this was possible or would it benefit the car she has just over 70k on her

 

[Seatmann]

All of them are fine, yours is a VE type engine, not sure exactly what the VE stands for though. Anyway yeh you could do away with the egr and fit the PD150 intake. Regarding the egr you could just pull the vac line off the top, the egr is the big round one on top of the intake, left hand side when you're looking at it, then just plug the vac line with a bolt or something and that's it deleted. That way you can keep the asv (anti shudder valve) which helps with shiutting the engine off smoother. As for mileage, it doesn't really matter, these engines are good for 500,000 miles anyway if looked after. Really tough sods.

It's a distribution pump engine, all the fuel metering and timing is done at the pump. Old-fashioned diesels have a purely mechanical pump, the 1.9 TDI engines have sensors and actuators inside the pump so that the ECU can fine-tune the timing and duration of the injection quantity. The hard lines from the pump to the injectors are necessary to maintain the injection pressure. The injectors themselves are simply spring-loaded non-return valves (albeit with very well-engineered nozzles). There's a VAG technical document summarising the way this engine works that pops up on the web every now and then, currently can be found at

PD injectors are completely different and can't be fitted into a non-PD head.

 

[d1n93r]

Oh ok. Does anyone have a guide on how clean the egr and manifold on this engine

 

[Seatmann]

Just ignore the egr cooler part, that's just for the states but the rest is much the same.

Keep an eye on eBay for cheap allard pipe I got mine for £30.

 

[Muttley]

The TDI 150 does have an EGR cooler, but Seatmann's right, the ASV does not.

There are larger injectors that can be fitted to the ASV head, I think they come from one of the van engines.

 

[Seatmann]

Don't mind Muttley, he's obsessed with PD 150's

 

[d1n93r]

Well he seams to know his stuff. Think I'm gonna clean out the egr out tomorrow I'll let u know how I get on.

 

[Leon2012]

yours is a VE type engine, not sure exactly what the VE stands for though.

"The VE in the name of the Bosch pump used in the VW diesels and many other small diesel engines stands for "Verteiler", which is German for distributor or divider."

be carefull when you disconect the EGR. i did mone the other week and started getting a fault code and engine management light. mine is a 53 plate but 2004 model year. everything i had read suggested i could just blank it off.

 

[Muttley]

@Leon2012 - good link, thanks for that, and the translation for VE = verteiler = distributor. For reference, PD = Pumpe Düse, which I always translate as dosing pump, but in English engineering terms it means Unit Injector.

 

[d1n93r]

well i didnt take it off in the end. i just took the hose off the end and had a look in and it looks clean enough for the mean time. but was wanting to know if i can change the elbow to a silicone one. and what exactly are the vacuum lines for and what do they do have thought about changing them to silicone ones too.

 

[d1n93r]

anyone?

 

[Seatmann]

Change them by all means but do the vacuum ones one at a time or you'll get lost, they're for the egr system and the turbo as it uses a vnt mechanism. Anyway for diagrams etc go and visit that site I linked

myturbodiesel.com and the tdiclub.com, both have all the info you need. Just follow diagrams for the golf or jetta with nthe ALH engine as it's much the same setup as the ASV.

 

[d1n93r]

And will they still be ok with the push fitting or should I get cable ties for them? Had also looked at changing the elbow from my erg valve. I know what pip I need but is the original clip still ok to use or do I need to put a new jublliee clip on it?
