Clatter on A4 at less than 2500 revs
 

All,

Any thoughts? Just this morning, my A4 1.8t has developed a clatter when
the engine is revving lower than about 2500 revs. No other symptoms - goes
fine, although I just turned around and came back home!

Sounds like a gearbox type noise, but open to suggestions.... Sounds like a
diesel at low revs.

67000 miles - full Audi service schedule etc.

Oil was fine (some of the suggestions), so called out RAC.

Looks like the cam belt is quite loose (can't be right - thought Audi cars
corrected this automatically?).

Car towed into Audi today - will let you know the outcome, but sounds
pricey...!

It was the cambelt tensioner - the result was a bill for £580 from Audi.
Great.

Still - at least no further damage to the engine!

Re: Clatter on A4 at less than 2500 revs
 

It sure sounded like a cam belt tensioner from here.
Hopefully you didn't bend any valve stems or crater a piston crown...

Probably the cambelt tensioner came loose. There is an updated design for this
condition.

Glad to hear the problem is fixed without major money paid.

Could you pls post model year of your car as well as part number
of revised tensioner (and/or when the revised part was issued,
if you happen to know).

Am very curious to figure out from what time the factory started
using the revised tensioner in regular assembly - before or after
my car was made . . .

/Robert

Re: Clatter on A4 at less than 2500 revs
 

Its a 1998 1.8T AEB.
The slightly annoying thing is that when the main dealer replaced the timing
belt, about 14 months/35K miles ago that is all he did. No recommendations
about revised parts !!!
This time I decided to get my hands dirty, save £400, and fit the latest
parts.
The AEB is now being fitted with the tensioner from the non-turbo 1.8 I
think..

Tensioner 058 109 479 B
Roller 058 109 243 C
Belt 153 teeth 058 109 119 C

Re: Clatter on A4 at less than 2500 revs
 

Aaak! Get your timing belt changed out after 65k. I have a '99 A4 1.8T and
the timing belt broke [while driving on freeway no less!] at 78k. This is
not uncommon if you have been following posts here - even though Audi
recommends change at 105k.

Learn from the experience and mistake of others - please! My car has not
been the same since!
