When I had a booming noise that seemed to blow back throught the air box on my 115 51 plate tdi with 132 k miles it turned out to be wear on the cam lobes. There was no smoke and it started just fine but just sounded like a tractor also. I had to have a new cam , cam shells, tappets, cam belt, water pump, air mass sensor as the back flow of air knacked the old one. Price inc a oil change at a VW specialist in Lincoln

Hope you can get away with the cam ,my tappets had been badly worn by the cam. I guessed it was down to non PD oil being used or oil being used for too long. Let us know what you find ! ! !

I'm sure there is a TSB on this, "Noises/gurgling on intake system" - I would check but my tis is broken at the moment.

Well as said my TIS was down so I couldn't confirm it at the time, here's the TSB but its for auto's and a slightly earlier build (although that could be when it was built, just not reg'd until 03)

 

 

 

TECHNICAL SERVICE BULLETIN No.53/2002

Car and Light/Medium Commercial 30.05.2002

 

 

Section: 307-01B

 

Model: 2000.75 Galaxy with 1.9L TDI engine (85 kW) and AG5 automatic transmission, built from 10.12.2001 to 14.03.2002 (build code 1E to 2S)

 

Markets: All

 

Subject: Noises from the intake system (in particular a charge gurgling) during overrun

 

Summary

 

Should a customer express concern over noises from the intake system (in particular a charge gurgling) during overrun, the probable cause is excessive boost pressure and air swirl in the turbocharger intake tract. To rectify this concern, the powertrain control module (PCM) with software level 1516 should be removed and a PCM with software level 1561 should be installed. The boost pressure and subsequently the air swirl are reduced during overrun with the new software.
