Replacing Diesel Injectors on my VW Transporter T4 2.5tdi AJT/ACV | Fix start issues & more power!
Вставка
- Опубліковано 30 сер 2023
- Our VW T4 Transporter with the 2.5tdi AJT/ACV 5 cylinder diesel engine developed slow starting issues over time. Although it ran fine when started, it took a lot of cranks of the engine to fire up and produced a fair amount of smoke while cold.
In this video I show how I changed the original Stanadyne diesel injectors for the Bosch injectors used on the ACV version of this AJT/ACV engine.
After the swap the engine ran beautifully and starts immediately - even without any ECU tweaks.
I recommend you use penetrating fluid and a diesel injector removal tool, which is like a small slide hammer.

Fantastic video mate! So helpful and thanks for taking the time to do.😊
Thank you. Glad it was helpful!

Cool!
Hi, thanks for posting a great video.
I have T4 ajt 2.5tdi with stanadyne injectors (200K miles). It was remapped years ago by TH performance and runs really well with plenty of power, i also added a VW intercooler.
In the last year the van blows a lot of white smoke on start up, I think it's time to change the injectors, do you have a link to the bay seller where you got your reconditioned bosch ones, also is there a reason why you didn't buy the Project Power PP0.5 injectors that always get great feedback on T4 forums.
thanks
Thanks for the great feedback. Sounds like your injectors are doing the same as mine did. I bought the refurbished injectors from a guy on Ebay (link: www.ebay.co.uk/itm/384567842847). The only reasons I didn't go for the PP0.5 was cost and I hoped that by using the Bosch ones I wouldn't need a map again.
thanks@@AdventuresAutomobiles
Planning to do the same. Any smoke issues without adjusting the injected quantity? Cheers
No, the van was smooth and had no more smoke on start up with the injector change.
What cost were the injectors please?, and why did you change the position of the wired one ? Cheers 👍
I paid about €250 for the refurb Bosch injectors. On the 102 engine variant the longer injector is in the 5th cylinder (it doesn't need to be) and that fuel line is also the longest - so it made it easier to fit in that place with minimum bending of the fuel line.
I have a whit smoke in cold start? Maybe it can be the injector? Have you a code for the tools to extract injector? Thanks
If you have old Stanadyne injectors in an AJT, then probably yes. This is the tool I used to extract the injectors: amzn.to/48sFiQz
@@AdventuresAutomobiles never change the injector
It s a D5252T on Volvo, I think it the same engine with ael, avc, ajt, mechanical injector. Thsnks for your help. Good bless you 🙏
Where did you get your new injectors from?
I bought them from a seller on ebay - this was the listing: www.ebay.co.uk/itm/384567842847
Did terry not remap then? Just adjust pump quantity -
Not on the injector change in our instance. The map was done before and only needed tweaking. We could've pushed for more power but I wanted better mpg and no smoke.
What type of intercooler is on that T4?
It's an uprated alloy L200 intercooler.
i do 360000km with injectors no problem
Wow! That's incredible.

My pump timing had already been done with a new belt.
