Checking and cleaning MAF sensors

Thanks YNOT. Another job for me this weekend.
Is it correct that a catch can will stop this getting dirty again.

So I think I need to replace the air flow sensor when a finish rebuilding this engine

You can just clean with MAF cleaner from SCA, just make sure its dry when you replace it. If
you decide to buy another keep this for a spare. and yes a catch can will prevent fumes fouling the sensor

can anyone tell me does the car need to be warm when you clean the sensor or is it ok when cold .
cheers neil

You can clean it any time, spray heaps at the wire, DO NOT TOUCH wire with fingers or anything else.
Just make sure its dry before you re install it, While you're cleaning it some ppl dis connect battery at the same time.

thanks TD

Has anyone done this on the CRD? Going to have my head stuck under the bonnet this weekend and I have a can of MAF cleaner so I want to give it a bash.

I pulled out what I thought was the MAF a couple of weeks ago but it was flat and shiny, if that makes sense, nothing link the photo at the start of this thread.

Cheers for the top info Tony!
