Hi Chantal


 


When I asked my question, I was led to believe that there was a mechanic there to answer me more or less straight away.


 


I would not of minded waiting a day or at least receive a message back with an ETA for my answer, I have waited 3 days and, I have paid money in good faith.


 


I would like to close my question and a full refund please!


 


Regards

Name is Greg, My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back,

If the warning screen with the triangle came on but the check engine light did not then check this TSB for your vehicle and show this to your dealer to get this fixed .

If the check engine light did come on then this engine timing chain is known to stretch and cause you this problem.

the chain elongation indicator at the front side of timing chain case is overlapped with that of the chain elongation indicator at the reverse side of timing chain case.

6.Check the end top point "A" of timing chain cross section surface and the point of chain elongation indicator which is fixed in Step 5. When the end top point "A" of timing chain is positioned at the left-hand side of chain elongation indicator, it is unnecessary to replace the timing chain because the timing chain is within the specified length. When the end top point "A" of timing chain is positioned at the right-hand side of chain elongation indicator, it is necessary to replace the timing chain because the timing chain elongates more than the specified length.

7.Install the upper chain guide. CAUTION
Completely clean the old FIPG remaining in the clearance between the mating parts.
Install the cylinder head cover within 3 minutes of applying the liquid gasket.•

8.Apply a 4 mm diameter bead of liquid gasket to the point shown in the illustration.

Liquid gasket: THREE BOND 1217G or equivalent product.

9.Installing the cylinder head cover, tighten the tightening bolt according to the following procedures.
a.Temporarily tighten the tightening bolt in the order shown in the illustration.

Tightening torque: 3.0 ± 1.0 N⋅m
b.
Tighten the tightening bolt to the specified torque in the order shown in the illustration.
Tightening torque: 5.5 ± 0.5 N⋅m

10.Install the ignition coil.

11.Use the scan tool MB991958 to select the timing chain maintenance. Initialize the learning value. Refer to GROUP00, General − Precautions before service − Timing chain maintenance P.00-33.

NOTE:
Carry out the initialization even if the amount of timing chain elongation is normal. As a result of this, it is necessary to replace the timing chain before the timing chain interferes with the other components when the next warning lamp illuminates or the diagnosis code No. P0012 is output.

If you still need further assistance then please don't rate, just get back to me with the reply button, and I will get back to you or inform another expert to assist.
Also there is no extra charge after accepting .
Kindest regards Greg
