Loss of power steering and battery light


This morning during my journey to work i suddenly lost my power steering on my 2002 Audi A4 1.9tdi. Then shortly after the battery light came on. The car continued to drive, and the heating/radio etc worked too.

When i finally got to work i parked up and switched off. I then tried to restart the car but the battery is completely dead. However on my way to work 30 mins earlier the car started fine.

Im hoping i just need to replace the battery, but was wondering if these symptoms were of soemthing omre serious

I look forward to your response

Hey there Cyber,

Classic symptoms, belt failure. Be glad you don't have a serpentine belt, the engine would have overheated too.

If you work close to home, it may even be a serpentine and just didn't have time to overheat.

At any rate: One of your belts powers both the Alternator and the Power Steering Pump. That belt is either very loose or laying on the road between your home and workplace.

The good news:
This is one of those lucky circumstances where the more that looks like its broken, the cheaper and easier it is to fix. If it was only the Alt. or P/S that would mean all sorts of diagnostics, tests, etc.

Both at once? The belt.
The cost? Less than $20.00 if serpentine. Less than $5.00 if not.

If the old one is still hanging there, it will be useful when getting a new one (to size it).

Let me know if you feel like replacing it yourself.
If it's a serpentine, click here for the procedure (the trick) to get it on.

Once the new belt is on the only thing you'll need is a jump.

Any additional questions? Just comment me back.

Thanks for using FixYa

Thank you Mike!

I have a 1998 Ford Expedition and I had the same problems: hard to steering, battery light on, and getting hot. It was my Serpentine belt. Thank you soooooo much!

It's most likely just the battery but check your power steering pump and alternator drive belts to make sure they are not loose.

Sudden loss of power while driving

Hi There, You need to check you automatic transmission fluid (ATF) levels which controls your power steering, if it is drained you need to top it up if the container is cracked, you need to change it. Next, your engine needs retuning to stem down the excessive revving.
