Returning used car part
Discussion
So ignoring advice i bought a cheap MAF sensor (£35 Vs £120 for genuine). It initially cleared to fault code I was getting and starting improved but after just 3 days it has failed throwing an EML.
The company i bought it from is a German parts specialist who sell all sorts including genuine bits aswell. It says on their website they have a 30 days no quibble guarantee if you aren't happy with the quality etc. but then also says on their returns policy that any parts that have been fitted will not be eligible for return.
99% sure it won't come to a dispute over £35 but interested to know what the law is on this? Do I have to provide proof from a professional the part has failed somehow e.g garage report? To save hassle I could probably just say I haven't used it as you wouldn't be able to tell but rather be honest.

So you replaced a failed MAF with another (non OEM MAF) which worked for 3 days, and then failed.
How do you know that some other underlying problem isn't the cause? (For example, I know that oiled air filters can screw up MAFs)
You could well have a point. I'm going off an obdeleven reader and the internet's interpretation of the codes/live data it's giving me. I thought the original sensor had just run its course as it was over 100k miles old and then the second cheap sensor failed with the same code but as you say there could be an underlying cause. How do you know that some other underlying problem isn't the cause? (For example, I know that oiled air filters can screw up MAFs)
I think I will just bin it then and do some more investigating before I fit a replacement.
With non-OEM MAFs there is a degree of pot luck I think.
I killed an original Bosch one, and replaced with a supposedly identical OEM Bosch MAF (i.e. same part number) but already installed in a short pipe section for a different vehicle - I swapped them out and fortunately the new one worked fine.
A possible option if you can find out what other vehicles the same MAF part number is installed in.

Often it will be a dodgy plug not making contact properly . After 100k miles the contact points start to fail or a wire starts to go .
Clean everything up , clear the fault and away you go .
The basic diagnostic tools only tell you where the fault is being indicated.
The real diagnostic experts will get all the values and trace the true fault.
Most main dealer technicians only do what the machines tell them .

should that be OBD2?https://www.ebay.co.uk/itm/143928028916?hash=item2...

Cheers.
Ideally you need to check the incoming air system. Clean air filter etc. Also make sure the electrical connections are good.
You say the replacement MAF was ok for 3 days then the fault returned. That hints at either unlucky with a MAF that failed again or something else causing the same fault.
Check everything carefully before refitting a MAF. Even fitting a new OE one might not work if there is a problem elsewhere.

Thanks for the advice. I will buy a cleaning kit for the cone filter as perhaps it needs doing although it's only done 5k miles. Will also check/clean connections. I do have some live data from when I first got the MAF code but not really sure how to interpret it to be honest. You say the replacement MAF was ok for 3 days then the fault returned.
