Hello Experts
Need HELP
I have an E280 2009 MODEL WITH m272 engine and 722.99 transmission There is a weird noise with every cold start stays for few seconds , I recorded the sound but I could attach it here.
I removed the belt thought that may be the belt tensioner but the sound was still there . pookh pookh pookh sound coming from engine or transmission side.

Please help

Regards.
