Faulty EGR – teeth stripped

Faulty EGR – Teeth striped This week we had a Audi A4 with warning lights on, upon further investigation we traced the fault to carbon build up that caused the flap to seize.  We decided to strip the motor to investigate further and discovered the plastic teeth were stripped due to seized flap from carbon. The vehicle also had a blocked DPF due to the ongoing EGR fault.  As a result of the Carbon build our customer ended up with quite an expensive bill as the EGR is an expensive component to replace on many vehicle.  These types of repairs can be minimised by carrying out annual serving with addition of BG Products.  So our recommendation would be to treat your car early and prevent high cost component replacement.
