Mafs And Cleaning.

[Scorpiorefugee]

I'm not an avid user of this site as I'm too busy driving my S reg GLX TDI (155k)and now 52 Ghia TDI (As well, not instead of - these things are addictive!) but I have noted and suffered the problems associated with MAFs. Having had a Scorpio and scoured that website for an array of problems, I know that cleaning MAFs with carb cleaner has amazing results. Strangely, there seems no sign on this site of this applying to Galaxies.

 

I have raised two posts on the fantastic improvement in my S reg motor after I cleaned it but have received no feedback from anyone on this as an alternative to spending loads of loot on a new one.

 

Have I been lucky or do you all prefer to do things the expensive way?

 

I did have to remove the actual core of the sensor by taking out the tamper proof screws to get at mine for cleaning but that is actually much easier than taking out the complete air pipe insert.

 

Honestly, the improvement for 5 mins work is amazing and sustained, having done around 3500 miles since cleaning it just gets better..

 

Just a couple of unassociated questions. Is the unit in my 97 S reg 90 or 110 bhp 'cos the difference between that and my 52 reg is considerable. Also, is the cam belt or chain driven in the newer one? (Stated to be 115 bhp - 6 gears)

Hi Martin,

 

I'm not sure about your problem, mine was just lacking power above 2900 rpm.

 

However, you will need a can of carb cleaner - about 2 quid, and a set of security torx screwdivers with the hole down the middle. If you look at the housing for the MAF, you will see two screws with torx heads. (a 6 pointed hole with a pin in the middle) I picked up a set of tools for these from our local pound shop, er, for about a quid, some time ago.

 

If you can get the right tool, it is the work of moments to remove the screws and pull out the MAF. The hole has an O ring for sealing so a little bit of twisty pulling may be necessary. Handle it carefully and look into it and you will see a bit of shiny metal which is probably a bit grubby.

 

Don't poke about and don't use the tube on the spray can(if supplied, just flood the insides with cleaner and give it a little swill round and tip out the residue, maybe repeating for good measure - leave to dry and refit.

 

I am told that these things are delicate so go carefully.

 

That's what I did and got lucky.

 

I hope you get lucky also.

 

Ron
