Hi there this is my first post .

I have a huge problem with my 2001 audi a4 1.9tdi 130, the problem started about 2 months ago where i would be travling along at highway speeds and i could feel a slight chug from the engine everyone now and then. its now got to the stage it happends everytime i foot my foot down to damand power, if i maintain a steady speed its hardly there only just when i put my foot down.

Things ive done..
New fuel filter
New airfilter.
New oil & filter.
Cleaned EGR valve.
Checked for visible vac leaks.
New coolant temputre sensor (temp still sitting at 70c)

does anyone know what else could be causing this? as i dont want to start buying things that i dont need . many thanks

I had same problem 1.9 tdi 130, started off intermittently then got worse

Changed MAF sensor (recommended after few years especially after remap) fuel filter (light on alll the time) n done a mr muscle turbo clean

Not sure what done the job (mr muscle i think) but now turned into a beast and close to 177hp (remap)

Mr muscle turbo clean does work, google it, mate done it for a score!
