Thread: What happened to your Discovery 2 today?

Mine has a dealer fitted ARB bar. Whoever fitted it just used scotch locks to tap in. They were probably just ok when it was new, but did they cause some problems later.

D2a had a bit of a hissy fit about a week ago.
Early morning had to take missus to airport .. hit a roo.
Not a lot of of time to have a good look, but LH corner of bumper gone.
At the same time had to deliver 6x4 trailer back to friend.
On the drive to Mel, car had lost a lot of power .. more Tdi like, then Td5. Up the hill past Castlemaine had trouble holding 80, down to third power level.

Pulled up again and tried to be more sure of turbo hoses, etc ... but still had good turbo pressure according to TD5Spy, etc. No time as had to get missus to her plane too.
Anyhow got back home too lazy to do anything about it etc ...

Quick look(reminder) of what MAF values should be, nanocom connected and then compared to what the D2 was doing.

Yup! MAF values down compared to D2, so swapped D2s MAF to D2a and other way around(for now).

Just got back from test drive and D2a now has it's power restored ... new MAF time.

But the kicker!

D2 was originally owned by brother. We must have changed MAF wayyy back when(around 2017) due to whatever problem it must have had .. and solved. And then in about late 2018/early 2019 he got himself a new dual cab, and I 'stole' the D2 from him. It's been mine ever since!

So whilst swapping MAFs between the two TD5s, I noticed that the MAF going from D2 to D2a was a cheapie of unknown origin .. and most likely ebay special(I know the bro, he's like that). Other then the typical Chinese oval QC sticker on it, no numbers. D2a MAF had siemens and soem part numbers, etc ... ie. original stuff.

Goes to show, and I fully understand that cheapie MAFs can't always be relied upon, but this one can.

I can't recall the MAF values you should see on the nanocom, but the original Siemens one would spike at a max mid 400s for a fleeting second, then max would hold more steady like mid to high 300's, whereas the D2s ebay special would get into the 600s and hold mid to high 500s.
Anyway, swapping has now confirmed the D2a problem .. now the next problem is ... time to cheap out again? .... or not!
