2005 AUDI A4 User Comment / Complaint

2005 audi a4 avant is currently still under warranty but the audi dealership and audi of america will not replace a cracked coolant reservoir. the onboard computer came on, indicating a problem, but there was no leak. however, the crack was very visible and will most likely spread further resulting in a leak. the crack was most likely caused from the excessive heat under the engine hood. i believe this was a serious flaw in materials used to manufacture the reservoir.
