1. Improper installation of the Volkswagen m6 recall. Or defective part on a Volkswagen tdi 2004, or faulty design. 2. The lower egr cooler pipe #038131521cc. This pipe cracks causing improper emissions and exhaust gases into the engine compartment next to the cabin air filter intake. Poison gases in the vehicle interior. 3. Replaced 3 cracked parts in 1 year. Volkswagen claims there is no problem and will not look into the matter.
Vwoa had a recall campaign for the egr cooler system on 2004 and 2005 vw tdi's. Subsequent to the recall campaign, the lower egr flex pipe is known to crack on numerous vehicles in which the recall campaign was performed. When the egr pipe cracks, diesel exhaust is sucked into the cabin when the heater fan is operated causing discomfort and light headed for the driver and occupants. Vwoa has refused to address the problem and offers no solution to the vehicle owner or a fix. Not only is it an expensive repair, but it can also be causing medical problems for the driver and occupants. My egr pipe was cracked for 2-4 months before I realized what was happening. It may have been cracked longer with out my knowledge.
