s60 Loud pop / bang then black smoke and chugging/misfiring

Also have the loud chugging/popping when oil filler cap is removed, have tried taking pipe off TCV and blanking it off but still noisy, TCV is pulling a vacuum.

Look into the boost solenoid mentioned by me in post#5 and get yourself some diagnostics too.
For less than a tenner, this will help you enormously http://m.ebay.co.uk/itm/Mini-ELM327-...EAAOSw-dBTwoEE

A cheap vacuum tester will also pay for itself many times over.

Cheers for links, yeah planned on getting the vacuum tester ( pay day on Thursday, lol ), will get diagnostics too as plan on sticking to the s60 for a while. Your vids are worth there weight in gold, everything explained as it should be and in simple terms, many thanks for taking the time to do them.
