# Service bulletin LI05.20\-P\-080257

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's 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
