Service
If timing chain is suspect, perform the following:
• Complete the DTC entries according to guided fault finding (GFF).
• Remove the lower timing chain cover, see Repair Manual Group 15 in ElsaWeb.
• Check the timing chain tensioner as follows:
• Compress the tensioning rail of the timing chain (illustration 1, No. 2) by hand against the timing chain
tensioner (Figure 1, No. 1).
Inset. 1: timing chain tensioner
Inset 2: tensioning rail the timing chain
arrow: Direction of pressure on the
tensioning rail of the timing chain
Figure 1) section of the timing chain drive.
If the piston of the timing chain tensioner cannot be compressed by hand after several attempts (Figure 3, green
arrow), further engine diagnosis is required.
Tip:
Inspect intake camshaft and camshaft bearing for damage.
If the piston of the timing chain tensioner can be compressed in by hand (Figure 2, red arrow) the timing chain
tensioner has failed, and further engine diagnosis may be required.
Tip:
If engine noises or no start condition remain, inspect pistons and valves for contact damage. If engine damage is
noted, cylinder head or engine may need to be replaced.
