  Summary

  Complaint Customer states that the yellow "Coolant" message is populated in the instrument cluster. The following DTC is found stored in the PTCU: P2B2A7A - The speed of the 'Coolant pump' component part is too high. A leak or defective seal was detected Notes on fault code: The fault code concerns the right rear 15 W pump on the side of the transmission (Figure 1, position C). The fault code concerning the speed that is too high is set because of air in the system (emergency dry run function) IMPORTANT: This LI DOES NOT APPLY to model year 2024 and newer vehicles. For model year 2024 and newer vehicles pump PN's A0005009100 and A0005008900 are the correct pumps Cause Air in the low-temperature coolant circuit Remedy PLEASE READ ALL THE STEPS AND FOLLOW THEM IN ORDER. Step 1: With the engine cold, use Xentry to activate the two pumps at the passenger front. As they are running, remove the cap from the low temp cooling circuit reservoir and observe the coolant. • If it overflows the reservoir, or blows out upon removal of the cap there is a restriction somewhere in the coolant lines. • This can take the form of a physical restriction inside of one of the lines or pumps or a damaged or kinked hardline or rubber hose. • Activate each pump in succession and listen to it using a stethoscope or by placing an ear to a screwdriver or other implement placed on the pump • Compare the sound and feel of each pump. An improperly functioning, bled, or faulty pump will make a very distinct churning noise. The pumps should be near silent and should not vibrate or heat up. • If you find a pump that is making more noise than the others it is most likely pulling in air from somewhere or is encountering a restriction (refer to the first point in this section) • If nothing of note is found, proceed to step 2. Step 2: Disassemble underfloor paneling and wheel well interior trim at front right to gain access to the two low temperature pumps. Take note of or photograph the part number of the pump holder, along with the production date. Step 3: Check the installation position of the pumps at the front right of the low-temperature circuit (Fig. 1). Below are the correct specified part numbers at each location: • Outer: A 000 500 5500 (Fig. 1, position A) • Inner: A 000 500 3800 (Fig. 1; position B) • If installation position is NOK, continue to step 4 • If installation position is OK, skip to step 7 Step 4: Photograph the pump part numbers at the front right so that the QR-code/DMC code and the part number are visible and legible save the pictures and label them appropriately if a TIPS case is required in the future. Step 5: Replace the affected pump(s) (where the installed part number differs from the specified part number, see specified part number in step 3). Step 6: Use a vacuum bleeder to fill the cooling system of the low-temperature circuit. Step 7: Vent the cooling system of the low-temperature circuit using XENTRY. • NOTE: The cooling system of the low-temperature circuit is vented in various stages. To start with, the pumps at front right are actuated at approx. 30%, then 50% and finally at 100%. At 100% actuation, the valve of the coolant circulating the pump at the side of the transmission is opened (Fig. 1; position C). Please ALWAYS observe the following points during the venting procedure: • The front right pumps always run simultaneously. These pumps must NEVER be operated separately of each other for actuation or for test purposes. • The pump at the rear of the transmission must run permanently after being actuated. If the pump only briefly starts-up and then stops again, it is in a so-called emergency dry run mode because there is too much air in the system. Please repeat the venting routine. If the rear pump at the side of the transmission remains in the emergency dry run mode, create a TIPS case, add the previously discovered findings to it and send it to the technical support team. See attachment for further instructions.

  Summary

  Complaint Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy Check for external damage: You can identify a damaged headlamp in the following way: For headlamps with a closed system 1. Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. 2. If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system 1. Check the headlamps for any external damage and seal off the vent, then make sure the cover caps are latched correctly into place. 2. If the headlamp exhibits any external damage, replace the headlamp. Note: External damage to the headlamp does not present a warranty or goodwill case. 1. Clear fogged/condensed LED headlamps and LED rear lamps: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood or trunk. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). 7. If the condensation has disappeared, nothing else has to be done. Note: If defrosting has been performed, you can skip the first step. 2. Leak test of headlamp with overpressure: • Connect test adapter to pressure tester. (Figure 1) • Check test adapter for leak tightness. To do so, connect plug and coupling (picture 2) and apply a maximum overpressure of 30 mbar. The pressure must remain constant. If the pressure does not remain constant, use a new adapter. • All vents have to be sealed with sealing compound and the existing diaphragm with the stamp (picture 3 [3]). (Picture 4) Make allowance for the different headlamp variants here (there are different outlet openings). • Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. • Plug the adapter onto the diagnostic socket on the headlamp housing. (Picture 5). • Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged (picture 6). • If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is tight and there is natural physical condensation. • If a higher pressure drop than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. If the pressure test is not passed, the headlamp is leaky. If the cause cannot be rectified, the headlamp must be replaced. Note: If the headlamp is replaced, no dry packs may be installed on the new replacement headlamp. AR82.10-P-5455WT was created for the pressure test. **NOTE - As of Sept 2025 the pressure testing tool is not finalized and may require modifications to fit properly. This AR can be used as a reference manual for all closed headlamps. In the event of an open headlamp system, the vent ducts must be sealed before the pressure test.

  Summary

  Complaint Headlamp, front fog lamp leaky or fogged Cause Fogging of the headlamps is a natural phenomenon, which can occur under certain climatic conditions. It does not lead to any technical impairment of the headlamp. If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". Remedy Headlamp: Remedy 1 Clearing fogged/condensed LED headlamps: 1. Drive vehicle into workshop (temperature higher than +18 °C/+64.4 °F) and connect the exhaust extraction. Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing of fogged/condensed LED headlamps and LED rear lamps on electric vehicles: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). 2. Connect battery backup via a charger. 3. Open the front-end flap and ensure sufficient ventilation. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine. 3. Open the hood. 4. Switch off the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Note: If there is no visible reduction in condensation, check the headlamp for malfunctions. (see Remedy 2) It is not physically possible to defog the headlamps completely. Fogging does not impair the operation or the service life of the headlamp. Remedy 2 A defective headlamp can be identified as follows: 1. Check the headlamp for external damage and that the cover caps and the diaphragm are correctly seated. 2. Check the electrical connectors of the plugs and pins. 3. Check for leak tightness according to LI82.10-P-078307. The test can only be conducted on headlamps. 4. If the headlamp or the rear lamp has any external damage, replace the component part in accordance with the WIS instructions. Note: External damage to the headlamp/rear lamp or faulty seating of the cover caps does not present a warranty or goodwill case. Note: With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. • Open ventilation system LI82.10-P-078302 • Closed ventilation system LI82.10-P-078304

  Summary

  Complaint Frequent rear view camera flap actuations and/or noise associated. NOTE: Rear view camera functions are NOT affected and still perform in accordance with regulatory requirements. This is only for customer satisfaction purposes. Cause This is not a malfunction, but an intended system behavior. Calibration of the reversing camera is in progress. Remedy For customer satisfaction purposes, an optimization has been implemented to reduce the quantity of rearview camera flap actuations for calibration. Update both control units and perform on SCN coding: • A26/17 (Head Unit) • N62/* (PARK Control Unit) IMPORTANT: After both control units have been SCN coded, the "Movable 3D View" feature in the head unit will no longer be available. With this change there will be two distinct differences: 1) The "3D" icon when in the top down vehicle view, will no longer be present on the head unit. 2) The digital rendering of the vehicle with the ability to spatially move around the vehicle is no longer possible. This view is replaced with 2D static images of the left and right sides. Prior to releasing the vehicle, please verify the following: • Rear camera flap when calibrating after a key cycle bus sleep will stay open to 29 MPH and then close. Will reopen, when calibrating, at 9 MPH. • The head unit screens mentioned above appear the same as "View AFTER SCN Coding" as shown in the attachment.

  Summary

  Complaint Engine vibrations perceived at low rpm. Fault codes for the camshaft position of the intake camshaft (P001100, P001104, P001200) or exhaust camshaft (P001400, P001404, P001500) may be stored. Cause Continuously fluctuating oil pressure in the central valve may lead to damage to the filter screen on the central valve. This can result in damage to the filter screen or the filter screen breaking loose. The resulting loss of oil pressure prevents proper adjustment of the camshaft adjuster. If the filter screen breaks loose, parts of it may settle in the camshaft adjuster or in the camshaft. If there are parts in the camshaft, they can pass through the oil supply bore to the last camshaft bearing (i.e., the first camshaft bearing behind the adjuster) and cause damage there. Remedy 1. In cases in which only the screen of the central valve is damaged and no metal particles are found in the oil filter, the following parts must be replaced: - Always both central valves - The camshaft adjuster of the damaged central valve 2. In cases where the screen is completely missing and metal particles are found in the oil filter, the camshaft bearings must be checked. If any damage is visible there, proceed as follows: - Both central valves - The camshaft adjuster of the damaged central valve - The camshaft bearing housing (camshafts are already included here) - Oil change with oil filter
