Question about Audi A4

1 Answer

Hi I have a Audi A4 which the tensioner bolt broke and this made the timing belt become loose, replaced with new tensioner and set the timing up, car wont start, removed the rocker head cover and all the input valves are down does this mean that the valves are all damaged, the car is 20 valve 1.8.

    Its not the intake valves its the exhaust valves that are all down the exact same amount, the valves look to be in position its the buckets that seem to be down.

If the intake valves are down you will have to remove the head and replace the valves. A compression test will confirm the issue. If the fact that the motor turns over to fast is not enough to convince you. Some motors are designed not to bend the valves when the belt slips or breaks, unfortunately , yours is not one of them.

    Does it turn over fast like the spark plugs are out? Have you run a compression check? I'm sorry but if all four valves (intake OR exhaust) now have excessive clearance between stem and rocker arm or cam and shim (are not coming back up) and there is no compression , you have bent valve stems and need to replace the valves.

Should i replace audi 2008 a4 thermostat along with timing belt and water pump 120,000 miles

I would - but the timing belt would be overdue at 120K if a 2.0L engine. From the service interval linked below:

"At 110K miles (175,000 km) replace timing belt (2.0L engine only). Check condition of timing belt tensioning system, dampening pulleys, and idler pulleys and replace if necessary (2.0L engine only)."

1997 Audi a4. Replacing thermostat. Can't get the housing off due to Cam belt in the way. How do I remove the belt? It's not the belt that runs off the alternator. It's a wider belt. Not...

If you index the engine properly (put cylinder 3 at top dead center, verified by alignment of timing marks on cam sprockets and crank pulley) you can remove the belt safely - the cams won't spin. But to get the housing off, you can slide the belt forward on the cam sprocket without removing it. Do it carefully - I've slid them halfway off and had a friend hold it while I tapped the channeling plate downward and off to replace the thermostat. Then slide it back in place once the new thermostat is in and the plate is resecured in place.

How do i take the pressure off my fan belt on my 1.9tdi 2002 a4. is there a bolt on the tensioner than will release the pressure when turned??

Yes, there is a 19 mm hexagonal cap bolt on the tensioner. See the yellow arrow in the picture below:
Put a 19 mm spanner on the bolt and turn it in counterclockwise direction until the fan belt will be released. Then remove old fan belt and install a new one. See the serpentine belt routing diagram for a 2002 Audi A4 1.9 TDI:
CS = Crankshaft
F = Fan pulley
Gen = Alternator
T = Tensioner
AC = Air Conditioning
PAS = Power Assisted Steering

What should i expect to pay to have my timing belt replaced?

Including the new tensioners £250 I had mine done about 6 weeks ago but I also got a water pump at the same time. If you are doing it anyhow then do get new tensioners and replace the water pump they commonly fail on the 20v engine and most times thats the engine finished.

Hope this helps. Also I did not use my local audi garage as they wanted £350 and everytime it go's to audi it develops new problems when I get it back somehow my bill at audi is always over £500.

Hope this helps

This isn't too bad a job as timing belts and water pumps go, but then I've done so many timing belts and water pumps on so many different vehicles its all just a blur now!!

It is always recommended that if you release the tension from an old timing belt then you should fit a new belt and discard the old one.

I would also urge you not just to fit a timing belt. Buy a whole belt kit. You should change everything the belt touches which runs on a bearing, and apart from the water pump, it will all be included in the belt kit. The water pump is purchased seperately.

If any of the bearing-run components pack up then it will be just as devastating to the engine as a broken timing belt, because the timing will jump several teeth and valves and pistons will collide. The belt may even sheer or snap.

It is for this reason that if I ever get a call out for a routine timing belt change, I always advise the full kit, and the water pump.

It may sound a bit expensive to be replacing items that may not require changing, but if you think its only once every six years or so then its not that bad.

It is also very important to observe the torque settings for the center bolts of any pulley wheels (idlers and tensioner). If you whack them up too tight then the applied forces from the timing belt, instead of being dissipated through the bolt and into the engine, will instead act upon the bolt and it will eventually snap.

Apart from that, the very best of luck with it.
