Hi having change the camshaft position sensor for a pricey sum of £74 with no shown improvements!! :angry: I will now be moving on to the MAF, what I want to know is do I have to completely remove the MAF to test it, or can I just unplug it and go for a drive around the block? Cheers :smiley:
-
Just unplug it thats how we tested ours. My new maf here today
-
Thanks mate. Did you have a rough idle at around 800rpm? When I increase it to about 1200rpm it seems to be fine?
-
Under heavy load it would be hesitent and mis abit idle seemed fine
-
Mines the other way round ha ha. But it's defo the MAF as its fine when unplugged. The dealer wanted £120 for exchange! I've read that people paid £65 for there's? Do you get the full sensor ie the round plastic tube too? Or is it just the screw in part?
-
Its the whole lot mate
-
I will get in touch with a friend who works a euro car parts then :) ha ha

Get a genuine VW one....all others are crap! I got a bosch one from GSF & it only lasted 9 months :sad:
-
VW ones are Bosch?

my new maf arrived today (bosch) genuine VW and fitted cured issues straight away. low voltage issue was the error and was running in limp mode and bringing tc issues on.

VW ones are Bosch?
But they are new, The Euro car parts Bosch units are reconditioned and don't last.

Having already spunked £75 quid away, why don't you do a more thorough investigation before splashing out on a new MAF. Unplugging it is not the be all and end all of diagnostic tests.
Thanks mate. Did you have a rough idle at around 800rpm? When I increase it to about 1200rpm it seems to be fine?
Does not scream dead MAF to me. It sounds more like a vac leak, or a dirty throttle body or injectors.
Your best bet is to find a man with VAGCOM and do a WOT run from 1k-redline in 3rd, logging MAF voltae/airflow readings.
(Only in a safe spot, coz speeding for diagnostic tests is bad mmmkay). Reading in g/s should be approx 0.8*power output.

Ok mate :) cheers. Seems to start up and run fine this morning. I cleaned my MAF yesterday? Will see how it goes. If it develops again I will fined someone with Vag Com. As for the £75 it came up with Camshaft Position Sensor on the fault code reader so best to get it done ha ha.
