2007 MCS Cold start rattle under load. Specific rpm.
Hi guys, will introduce myself properly later when I get a decent picture.
For now I have a problem that I could use some help on. I have used the search function but can't find anything that specifically relates to the nature of the problem I am having.
I bought the ar second hand from a garage, about a month ago. I have returned the car once for an oil leak and airbag sensor problem. I informed them of this problem but they came back and told me it was some form of heat shield rattling.
The problem only occurs when the engine is cold. When driving there is a rattle when you reach about 2000rpm.
I have tested this in first and second gear. Due to where i live and park i can't get anywhere to test in other gears without the engine getting warm.
Anything below or over 2k rpm the rattle stops.
When the engine is warm the rattle stops.
The problem only occurs when the car is actually moving. I can keep the car in neutral or drop the clutch down and there is no rattle.
Now i am by no means a car mechanic but i can't see how this could be a heat shield rattle. Surely it would also happen when stationary.
Thanks in advance,
