Fascinating Martin, what I love is that you show with the right diagnostic gear we can still work on our cars and save a small fortune on labour and garage fees. We are constantly being told because of modern electronics this is not so and yet again you have proven this to not be the case. I don’t know what your diagnostic tool cost but I bet it’s paid for itself over and over again!

Great improvisation mate, O2 censors are a real pig.

[@marksmith3469]

You are good at fixing cars and dealing with the problems that can arise

[@garytaylor5234]

Love your approach to a problem Martin. Nothing stops you does it

[@patrickedwards2630]

Hi Martin, love your videos. Keep it up. Might not have worked on this one but to stop the special o2 sensor sockets spreading on tight sensors you can apply a jubilee clip at the base. Works a treat usually.

[@steve4173]

Hi Martin, would be interesting to see how much this has improved the fuel economy. Thanks for another great video 👍🏼

[@andrewmarriott4033]

Our Astra sport came up with a fault on that sensor the other day I cleared the fault and luckily it hasn’t come back I’m not sure I’d fancy changing it you did a great job there 👍

[@cabdriveruk]

Great video Martin. Those sensors can be a pig to remove but you got the job done as you were committed after chopping the wires and sensor great job.

[@user-un2sx9qh4p]

Hi Martin, that rust in the chassis behind your hand looks like it might be worth fixing before it gets much worse

[@JP-ed2bz]

Perseverance.. the formula for success! Another job well done 👍

[@davidvickers9029]

Hi Martin, That was a pain but you never give up, well done Martin

[@martinburgess4814]

Great informative video glad you were able to sort

[@tonymccarthy9273]

Hi Martin thanks for the video , it was handy to see how difficult it was to remove, I think I did the right thing in getting a garage to change mine, I dreaded messing up anything, thanks again from Tony
