The car refused to play ball today, for some reason it did not fancy the 279 mile trip to Preston. I had been driving for an hour and all was well, suddenly there was the well known loss of power which would come back in fits and spurts but the throttle basically didn't want to do anything (unless you were in tiptronic and in 2nd in which case it would pull all the way to the red line)

The RAC man turned up 25 mins later to plug in his computer to find the typical mass flow sensor fault (code 0100) with the maf disconnected ( bit of a bugger as I'm using a pierburg for my synergy 2a ) it runs fine but the really odd thing is as soon as the car played up my jvc stereo starts saying "wiring mismatch check and reset"

Wtf ?

I've had all sorts of weird fault codes lately. Turned out to be dodgy earth's. I've posted on this in another thread.
Check your earth's. And replace that maf.
Thought the pierburgh maf was supposed to last for ages?

Are you going to put another pierburgh on or go for a bosch, or even one of those £25 eBay jobbies.
Just for info, my autobox ran fine in tiptronic, and only messed up when the computer was controlling it?
I was speaking to the brother in law, auto electrician, about the earth fault, and he said alot of landrovers suffered from bad earth's, but due to the faults thrown up by code readers, people would spend £££''s chasing a fault only to have it fixed by accident when someone cleaned the earth Connections up.
You live and learn.

Well the plan tonight was to put the original bosch one back in however whilst taking it apart it became apparent what the fault was. The maf plug from the synergy 2a is an audi part that originally was design for 5 wires whereas the freelander only uses 4 so there's a hole left for the moisture to get in.

Both the plug and the pin had become corroded so I spent ages cleaning them up only to find that the damage has been done and its still playing up so its back to plan A

That's odd, looked at mine and it's all dry, although it's not fitted at the mo. But no signs of corrosion. Maybe it was just put together badly on the production line.
You should be able to splice another connection to it.

It should have a plug in the receptacle that doesn't have a wire in it.

Yeah for some reason it doesn't. I spoke to the people who now do the synergy and they are going to see if they can supply me with another plug.
