    Hello Everyone,

    No matter if it's summer or winter, hot or cold weather — whenever I don't use my car for 5–6 hours or more, I get the same issue on startup. When I turn the key, the engine starts at a high RPM (above 1000) and makes a loud noise. After about 15 seconds, the RPM drops to normal and the noise fades away.
    My car has 110,000 km. Spark plugs have been replaced, and the oil was changed just a week ago.
    Some people told me this is completely normal, but a few others suggested that the timing chain might need to be replaced. Since replacing the chain is quite expensive, I wanted to ask you guys first:
    Has anyone experienced something similar?
    Would replacing the timing chain actually fix this issue?
    Or could there be another explanation?
    The sound doesn’t happen every time, which makes it harder to be sure if it's the chain or not.
    Thanks in advance!

    Post a code read, the usual problem is a sticking turbo wastegate bush but you could also have a worn chain system.

    Would you recommend replacing the wastegate bush?
    I will also post the code read here later.

    You can't replace the wastegate, it is a POS design, if you try and repair it you spend the next week using shims in a vain attempt to get the setting right and if you do like we did two weeks ago and fit a new genuine turbo, these fail because the new unit has a bodged on anti rattle spring which makes the brand new wastegate seize up (in two weeks) and destroy the new regulator motor, burn out the ECU and the suppliers don't give a **** leaving you high and dry.
