    Hello, it's just a thought but I wondered if any forum followers have had any serious benefit from a full engine rebuild or a replacement rebuilt head (full rebuild, followers/cam etc), regarding making the engine quieter. We've three diesels in the house, our T4 2.5 ACV (185k) is the noisiest...

    Hi, It's a 2001 2.5tdi auto 120k miles. Just come back from trip, where the engine has developed a loud metallic rattle. Sounds a bit like a loud sewing machine but metallic. Only happens or is most noticed at low revs, moreso if under a bit of load and fully warmed up. Sounds normal when...

    Hi all, hoping someone can shed some light on this. I have a 2.5 tdi acv 96 multivan I noticed a loss of power at certain revs about 4 months ago, I thought it could be the EGR, so took it off gave it a clean, the inlet manifold was sludgy so have this a wipe around too, nothing major. This...

    Hi everyone, I've recently bought my first T5 which I was hoping to convert into a camper to get out and about in. The van is a 2012 180 DSG 4Motion and is now at 69k miles. Each morning when I start the van, I can hear this noise, when the van is idling. Once the van is up to temperature I...

    Hi, I recently bought a 51 plate Caravelle, auto 2.5 TDI. 135k on the clock. 400 miles and two weeks later, I made the short commute home and noticed a fluttering noise on acceleration.

    Hi I'm a van newb and have had my 07 t5 for about a month now. Have noticed a disconcerting noise (a bit like that kind of purring noise of an old beetle) just for a minute or so at high revs on motorway driving. Van under 3 month warranty so need to get a diagnosis and fix, if necessary...

    Pulling uphill under acceleration, there is a 'pinking' type of noise, from the engine compartment. I guess there is a choice of sources. Very low mileage on this 2.5 2005, usual limp mode ills that I live with (reset on key en route). Removed turbo rubber hose to intercooler...found some engine...

    Hi folks The recent cold snap has made my rattly engine even noisier. It's a 1998 Multivan with the 102bhp ACV engine. I was told the "cambelt was done about 7 months ago", but have no verification of this. I get a real raspy rattle when the throttle pedal is pushed. I also have a whooshing...
