D5254T (to 2002, Audi) - A noisy engine - Is it OK ?

charliek1972 · Oct 18th, 2011, 22:39

Hi,

I'm new to the forum and have had a look around and can't find an answer so hope some of you can help.

I have a 2000 W Reg 2.5D V70 (P2) - I guess it's the Audi engine as it's not the D5 engine. I have owned it now for about six months and since purchase it has not sounded spot on but it is my first diesel so perhaps they all sound like this !

I think the noise could be getting worse but that may just be my ears and worrying about things.

I had it to a garage or two and was told the nosie was a bad tensioner arm spring on one of the drive belts so that was replaced but no difference.

I have posted the sound on YouTube on this link :- http://www.youtube.com/watch?v=HWfi0M9VBhg

I hope someone can tell me if it's a normal sounding 2.5D engine or should I be worrying !

The 'claterry' sound I am worried about is only really apparent when the engine is under load.

Cheers for any help.

Charlie

Hello and welcome. I've listened to the youtube clip and the main engine noise sounds normal. There may be an underlying clatter which is probably the vacuum pump pushrod - normal and harmless. The vacuum pump is on the front of the engine and is driven off the camshaft by a pushrod which tends to get noisy. The pump acts as a brake servo as diesels don't produce enough "natural" vacuum as is the case with a petrol engine. If you search this forum and the 850 / V70 96-99 forum (covers your engine and more info than V70 00-07 forum) you'll find posts on the pump issue. Regards.
