No need for that, unplugging the pipe does the same thing and it can easily be refitted for the MOT. It's actually 2.25 tonneBlock the EGR using a 1p coin, that makes a difference as well. I'm happy with it for a 2.5 ton car
I can get second hand - I just needed to hear that they don't fail very often. Cheers for the info
Well I won't split the difference over 1/4 tonne
And I didn't know that about that EGR pipe, only about putting a penny in the pipe
Well there's a contradiction in terms. "Nothing to do with how the engine runs but can confuse the ECU" (and thus affect how the engine runs)

I'm happy that it runs with the MAF sensor unplugged and EGR blocked. My biggest concern is getting a replacement MAF sensor
Anyway serious question - how exactly does a MAF sensor break? Is it circuits or some auto magic inside it?
You cannot have it both ways, a duff MAF can certainly affect how the engine runs by if only by causing the EGR to malfunction.If working correctly to measure amount of exhaust gas ingested when EGR is active. If duff and sending invalid signals to ECU can cause the ECU to become confused about air conditions and activate EGR at the wrong time. At least that's what BMW recon but what do they know. The runs fine when MAF is disconnected should be a clue.

I cracked an old one open and there us a little circuit board inside and not just a couple of wires similar to other units.The biggest concern is why are they so expensive? - if a new one was 50p you wouldn't be concerned
Are they difficult to produce/calibrate, or are they full of myrr - or possibly snake oil
That MAF was dead and I'm pretty sure the second one of a similar age is also...
