Regarding your reply in the previous thread
the garage will just take codes off the ECU, which can only detect sensors. The nearest sensor will be flagged if there's a fault. If you want to check if your MAF really is playing up, unplug it and start the engine. If the MAF's dodgy, the engine will suddenly run perfectly again.

This is assuming you don't already know this, obviously. Sorry if I'm teaching my grandmother.

I didn't know that one, so ta.
I've never had a MAF fault but the EGR went on my Saab earlier this year, but apparently that really is the EGR. You can clean it, or replace it, and the difference is about £60 so I just replaced it.

But both diesel MAF and EGR issues relate directly to EUcat4 diesel emissions regs (or whichever it is) which are a bit annoying.

Fucking shitty governments not letting me blow whatever shit I want into the atmosphere.

some aspects of the regs are rightly sensible
some are a bit ... odd. Is all I'm saying. The EGR solution is particularly strange.

I've had leaks in breather and booster pipes that were flagged up as MAF fault codes.
Obviously changing the MAF did fuck all. Now I've replaced all the hoses, the MAF has now gone. The gigantic twat.
