I have a 2007 A4, 2.0T 6spd manual.

I know the usual time to replace a timing belt & water pump is at 75k, however newer cars can go longer without replacement.

Sadly I've had the car for a year and a half and put on 55k already... so i am now at 75k...

75 or more?

 

audi has claimed up to 110 k

personally the 75-90k is where I would still do it and where I urge other drivers to do the same.

 

Bit of a newb question here. Whats going to happen if its not replaced in time ??

 

I have a 2007 A4 2.0 and just replaced the timimg belt and water pump, etc for the first time at 113,662 mileage. The service guy said if it goes, it WILL ruin the engine. It cost me $1729.88 total at my local dealer.

 

You got very lucky. Conventional wisdom, based on a lot of people's experiences, says to do it every 60-65k. If the tensioner fails, the engine is done. Don't play with fire - do it. Going 80, 90, 100k or more is asking for it.

 

2007 A4 in 75k miles check below
Ribbed V Belt - check condition and replace if necessary. Check tension of
belt drive with a manual tensioner and retension if necessary.

At 110K miles (175km) replace timing belt (2.0TFSI engine only). Check condition of timing belt tensioning system, dampening pulleys, and idler pulleys and replace if necessary (2.0TFSI engine only).
Brake Fluid - replace every 2 years regardless of mileage.

Spark Plugs - replace at 35,000 miles or 3 years, whichever occurs first.
Then, every 40,000 miles or 3 years, whichever occurs first.

 

As per to my personal experience you must go for 70-90k cause on that only i feel a smooth riding...

 

Thanks, I'll keep that info in mind for the next one! I was just relying on the service guy to tell me when to do things. Mine seem trustworthy.

 

Point is, a lot of the interval times initially spelled out by Audi have been since overturned by practical experience. There are a lot of smashed valvetrains out there that resulted from waiting 90k or more miles for a timing change. The tensioners aren't as strong as hoped.

 

is there any way of checking if belt was changed i have no service history with the car
