Knocking in area of the turbocharger Metallic knocking in front of car. Basically, during acceleration, this noise occurs in speed range from 2000 rpm to 3000 rpm.
It is possible to reproduce crashes reported by users. Under load, this noise comes from area of the turbocharger. Tolerance between shaft and sleeve in bypass valve connection area. Because of this tolerance, bypass valve linkage will vibrate over a certain range of speeds. This vibration can cause a rattling sound in bypass valve linkage.
The following repairs should only be carried out if all of specified criteria (Vehicle make/model, VIN, engine/transmission type code, PR number, part number, software version, coding...) are fully met. Otherwise, this measure will not correct problem and may result in a repair. In this case, we reserve right to refuse to resolve claim, and cost of removed parts must be borne by us.
In event of above failure, follow instructions below to install circlip specified in original parts catalog on bypass valve linkage.
1) As shown in picture, install clamp.
2) Press retainer (arrow 1) against turbine casing. For ease of installation, lever and bypass valve retainer must be aligned. Then slide clip until it stops on bypass valve lever (arrow 2).
3) Pay attention to correct position of clamp after installation. Check with a mirror if necessary.
Information!
You must install circlip without removing parts! CAUTION WHEN INSTALLING Retaining Ring: Do not stretch or bend retaining ring during installation. If retaining ring was overstretched during installation, problem may not be corrected and noise may reappear.
