3.0 TDI 272 quattro engine sound

[rastaman]

Good morning,

Recently bought a 2015 A7 3.0TDI and love the car. The engine has a very un-diesel like growl (IMHO) whilst at speed but when idling it has a clicking sound to it. Wondered if this were normal for this engine? thought I'd ask here before going into the dealer. I've uploaded a video clip, I hope the sound comes through ok.

Kind regards,

Hi Vladimir....welcome to the Forum

Not sure what to say really....yes it sounds like a diesel should but then not sure about the clicking...sounds quite loud for a metallic sound.

Best run it into a VW Audi specialist or dealer and get their opinion.....Cam Chain rattling or similar, best not delay getting it checked.

Let us know how you get on with it

Cheers  Trevor

Just a quick update, got a call from the Audi garage, there is an issue with the cam shaft which they will repair under warranty. A quick look online and there seems to have been a couple issues with the timing and sensors on cam shafts. Just waiting to hear from garage regards a time frame for the repairs. Got a brand new Audi A4 S line as a replacement, which is nice (ish) but its not my A7 :(

Got the car back today, and it has had all 4 camshafts replaced and the system rebuilt with new camcover seals and injector seals. Fault was due to timing chain tensioner. Not sure what all this means, just copied off the internal invoice. All sorted under warranty and after driving 2L TDI A4, pretty happy to hear the A7 rumble (sans the ticking sound on idle).  I had a look online to see if this was a known problem with A7's or the subject of a recall but doesn't seem so.

Bit odd, as I just bought the car 6 weeks ago via a main dealer used approved network. I'd have assumed this would have been checked before the sale.

Glad it was sorted under warranty for you! Fingers crossed there won't be any other issues Steve. Just watch your rear tyres if they're dunlops as they have a horrible trait of splitting bon the inner sidewalls!

This is something that was done to my car, but they neglected to tell me when I bought (it was a recall btw), I did ask if it had any major repairs (Audi Main dealer btw) They said none.

A week after owning it I had oil light warning, telling me to reduce speed etc, called em and asked why they’d sell a car with no oil in, it went back. 3 weeks later, oil smoke In the cabin on the M6, engine was covered In oil and all over motorway slip road - can you guess what they didnt do?
