Hi.

What codes are you seeing.

It is possibly worth getting the
compression of each cylinder assessed.

Not uncommon due to tbe design of this series of engine.

hi the code that stores is P1062

Check if you have compression on all cylinders (compression test)

Lets hope not..

Hi. Have you made any progress.

The seal of the multiair unit is often suspect with misfires

 

[leecharlton73]

it went in for mot last week and passed but emissions was all over the place the mot centre reckons its a lamdba sensor gone the code i get is P1062 cant seem to find much info on that code to be honest

Ok.

So its not a common fault code.

What did the fault description say?

I am not convinced a poorly switching lambda probe can make the engine loose a cylinder..

Have you had the plugs out??

See what colour they have become

Ok. I just googled p1062.

It is probably a manucacturer specific code.. but the ballpark appears to be valvetrain

That may well tie in with your rough running.

Have you got decent records of its oil change history.. has it had the screen filter flushed annually?

Friend had identical problem. Cost a fortune eliminating possibilities. He has full I.C.U replacement package, unit, clocks, fusebox etc, also a faulty multiair unit which , I believe, is repairable.

It is often a gasket failure.. but due to the engine design.. this shows as a misfire.. then low compression.
