i have a 2004 audi a4 1.8t lowered with 19 inch rims. a lil bit of work and my baby will b mint. wonderin if anybody had a, "front timing cover gasket coolant leak from front gasket" and can tell me about there situation with it please and thank you. i am also wondering y my temp guage rarely works and wen it does it goes to the centre(90)...

 

The coolant leak will be the water pump( if you're POSITIVE it's coming from under the timing belt cover), and the intermittent gauge is either a loose connection, or maybe an intermittent malfunction of the thermostat...
The stealership will soak you BIG time for the water pump...it IS a big job.
If you're not sure when (or if) the timing belt was last replaced, find out.
Usually it's a good practice to replace all the front engine belts along with the water pump at the same time as the belt, due the difficulty of access...the front bumper assembly has to come off...
