Service Technical Information 93/20 ENU 1001 1 Complaint - Vibrations in Passenger Compartment at 2,000 - 3,000 RPM (93/20) Vehicle Type: Macan S (95B) Model Year: As of 2019 up to 2020 Subject: Boost pressure hose between charge-air cooler and throttle valve Information: Unfavorable routing of the boost pressure hose can cause vibrations that may be transmitted into the passenger compartment. Remedial Action: Check routing of the boost pressure hose and if necessary: • • • • Install boost pressure hose correctly Re-align boost pressure hose Adjust bonnet and front apron Replace boost pressure hose Parts required Parts Info (if required): Part No. Designation Qty. 95B145993G Charge air hose 1 ea. (only if required) Required tools Tools: • • Torque wrench, 2–10 Nm (1.5–7.5 ftlb.), e.g. VAG 1783 Torque wrench, 2-10 Nm (1.5-7.5 ftlb.) Calliper gauge, e.g. VAS 6082 Depth gauge Preparatory work Work Procedure: 1 2 Remove front left wheel housing liner, see Workshop Manual '505619 Removing and installing front wheel housing liner'. Document the installation position of the charge air hose and the connection points on the charge-air cooler and throttle valve by taking relevant pictures before carrying out repairs. Information Also document your findings after each section if the measure has not corrected the noise problem. AfterSales Aug 7, 2020 Page 1 of 6 1 Service 1001 ENU Technical Information 93/20 Checking installation position of charge air hose Work Procedure: 1 Check installation position of the charge air hose and check whether the charge air hose is attached and installed correctly at the specified end points on the throttle valve Installation position of charge air hose and on the charge-air cooler Connection point for charge air hose on charge-air cooler. • • If the charge air hose is installed correctly, continue with Technical Information '505619 Turning charge air hose'. If the charge air hose is not installed correctly, install the charge air hose correctly and check whether this corrects the problem. Installation position of charge air hose Connection point for charge air hose on charge-air cooler 2 If the problem is corrected, no further action is required. • Aug 7, 2020 Page 2 of 6 If this is not the case, continue with Technical Information '505619 Turning charge air hose'. AfterSales Service Technical Information 93/20 ENU 1001 1 Turning charge air hose Work Procedure: 1 Loosen the hose clamp on the charge air hose, move the charge air hose at the throttle valve approx. 7 mm (0.28 in) from the alignment point Connection point for charge air hose on throttle valve by turning it clockwise and secure the charge air hose. Then, check whether the problem is corrected. Information Turning the charge air hose should relieve tension on the charge-air cooler mount in order to prevent this problem. • • If the problem is corrected, no further action is required. If this is not the case, repeat the procedure and move the charge air hose again by turning it approx. 7 mm (0.28 in) anti-clockwise. Then, check again to see whether the problem is corrected. Connection point for charge air hose on throttle valve 2 If the problem is corrected, no further action is required. • • If this is not the case and the vehicle was produced before 8/12/2019, continue with Technical Information '505619 Adjusting bonnet and front apron'. If this is not the case and the vehicle was produced after 8/12/2019, continue with Technical Information '505619 Replacing boost pressure hose'. Adjusting bonnet and front apron Information Carry out the steps described under "Adjusting bonnet and front apron" only on vehicles produced before 8/12/2019. This measure was already implemented during production on vehicles produced after this date. AfterSales Aug 7, 2020 Page 3 of 6 1 Service 1001 ENU Work Procedure: 1 Technical Information 93/20 Check adjustment dimension on both bonnet lock latches. To do this, use a suitable tool, e.g. a calliper gauge, to measure at position Bonnet lock latch -a(lower edge of lock latch to retainer plate) and write down the measured value. • • If the value is 37 mm (1.46 in), continue with Technical Information '505619 Replacing boost pressure hose'. The bonnet has already been adjusted to the optimised dimension. If the value is not 37 mm (1.46 in), continue with Step 2 - Adjust lock latch. Bonnet lock latch Adjust lock latch. 2 Adjust the lock latch by unscrewing the adjusting screw Bonnet lock latch -1- to dimension Bonnet lock latch -a-37 mm (1.46 in) and write down the difference in measurement on both lock latches. (Actual dimension compared to 37 mm (1.46 in)) The front apron must then be raised by the same dimension. 3 Aug 7, 2020 Page 4 of 6 To do this, remove the front apron. See Workshop Manual '631519 Removing and installing front apron'.
