Interesting article highlighting a growing problem in the motor trade.

Customers E90 320i in to diagnose a permanent misfire on cylinder 4.
This car was running poorly, so after a quick compression test we found zero compression on cylinder 4. A cylinder leak test then confirmed what we see below, a leak past an exhaust valve.
Customer approved removal of the cylinder head to get a visual confirmation, turns out a burnt valve was the cause - certainly not a common everyday issue but could’ve been worse.

Airbag diagnostics today on this E90 330d.
Airbag diagnostics can be tricky, It’s vital to have a competent skill level using a multi meter along with access to electrical wiring data to get accurate resistance readings when testing individual airbag components.
This one needed a new wiring ‘clock spring’ on the drivers airbag due to stage 2 igniter circuit shorted to earth.
... Correctly diagnosing a fault like this is far far cheaper than you’d expect. We see many garages who replace components hoping that they get lucky and replace the correct one.....a very expensive and frustrating method, diagnostic time is key.
