[Joop]

Hello,

i came up here with the same issue but may different occour.
I made the test as was written in: http://www.ross-tech.com/vag-com/cars/tdi.html
But the description was for an ALH engine and not for AEL.How can i know the right reference values?

What are the properly MAF,turbo etc. values?

Glad you fixed it, what nozzles did you fit?

Cheeper ones. WUZETEM from Poland. Although one was broken from new so i had to buy another one, they work fine. I am curious how long they will last. If they won't last long i will buy a better brand next time, but for now i am happy with them.

Problem is now solved. My engine got back to life and is reving like never before. Afterall the nozzles seems to be the fault for the lack of power. Thank you very much for the support. Great forum with helpfull people. Cheers

They are equivalent to these. 2 437 010 082 is the part number

I've seen those, given the price I assumed they were Chinese knock off's, which I've heard numerour horror stories about having huge flow mis-matches. This is why I went with a known brand.

I spoke to Bosch UK when I needed nozzles for mine and was told they were NLA, so I went with Bosio PP520's. Where are you getting OE Bosch nozzles from?

I work at an autoparts shop. I ordered the cheap ones to see if it makes any difference. I will see tomorow whats going on. They are manufactured in Poland.

Nozzles were not changed. I just changed the injectors (second hand ones). new Bosch nozzles cost about 70E a piece. I found some cheper ones but i havent heard of that company: WUZETEM (a set of 5 pieces costs as much as a single Bosch nozzle) They are from volvo d5252t and not from T4. If i could know for certain i would change them.

OK, and what about the nozzles?
Are you sure you got the right ones in there?

A lot of places sell aftermarket nozzles that are either too big or too small. They tell you it fits the car, and they tell you they are cheap, but in reality it does not work right.
Only ones that are 100% are Bosch, but they cost a fair bit.

For example the ones that are often fitted are Transporter T4 injectors and those have the wrong spray angle so smoke all the time.
There are some others (forget the company) that don't deliver enough fuel etc.

Then you got some messed up chips I guess.

But still shouldn't do 15 sec 0-100.
Did you change the fuel filter?
Are you sure the fuel supply isn't messed up somewhere?

If you do set the fuel adaptation in VCDS to 128, what is the IQ on hot idle (should be 4.4-4.7).

I re-read the thread, and if everything else matches up you got a bad injection pump.

The fuel filter is new. As for the fuel suply i feed the injection pump directly from a botle and no improvment whatsoever. No filter just feed and return directly in a botle in the engine bay. I changed 3 injection pumps and they were all doing the same.

Here it is without the pedal stop and the pedal to the floor. Same story

[bn-01-wso]

Check that the pedal actually goes all the way to the floor.
I don't remember the measuring blocks off the top of my head for the accelerator pedal %.

Make sure there is not something stuck under the pedal, like a floor mat or anything else like that.

If it definitely goes 100% to the floor, then you need a new set of chips.
Well you need a set regardless, as 45mg/str IQ is stock. I don't know what you bought from ebay...

I will completely remove the pedal stop and make a new log just to be sure. I pm'd you about your chips. Thanks
