Hi all, yesterday evening I accelerated quite hard and at about 6000rpm in 3rd I heard a loud pop come from the exhaust, the engine light came on and I had no boost, I read the codes after and had a big list! These are what I got: 30fc, 2f9e, 29f4, 29f5, 2abc, and 3100. Bit worrying really! Anyone know what may have cause this? I know a couple are probably because of my downpipes but there's a few I'm unsure of! I'm fbo with jb4 ran in map 5 btw.

You shouldn't get any codes for dp with a jb4. Have you cleared the codes and see if it replicates?

[lukepitt86]

Oh right, I assumed the catalytic converter codes would have been from this, yea I cleared them last week because of the same issue, but they've reappeared. It's booked in but he can't look at it until June 1st so just wondered if anyone has thrown the same bunch and maybe knew a common issue that causes them?

Ok so I cleared the fault codes took for another driver and got the pop and engine light on again with the 2abc and the 3100, the other codes have gone and stayed gone, any ideas what this could be? I'm reading possible tmap sensor?

I would check the connections to the map sensor in the first instance. Make sure the connection is as it should be and clean.

There is a n54 fault code list on bimmer bost with explanations & fixes

Thanks guys, shall check connection and I'll have a look on ***********. I haven't touched anything under the hood so maybe oil or something has worked it's way into the connection.
