    I am getting fail codes on Catalytic converter.. also on BanK 2 up and down on the O2. Do you think it is the Cat or the O2 sensors? or something else. ?

    Hi folks. My E36 318i Convertible has gone through three catalytic converters. Been replaced with a good aftermarket brand, but I just went through another one in about 5 months and it's apparently not from any physical abuse. I had knocked the first replacement version as it was hanging low...
  3. E46 (1999 - 2006)
    i'm doing a cylinder head gasket job and the bottom studs on my exhaust manifolds where totally seized up and i had to cut some off too. Instead of spending hours drilling them out I decided to let the professionals take care of it, so I took my two exhaust manifolds to the muffler shop. After...

    Hi, so I have the 116i. After a few weeks of owning it, the engine light came on in amber. After a few garage trips the lad said it was the cat. However I've noticed that if I try and accelerate a little to aggressive, the engine loses power and it feels as though the car is dragging back. I...
  5. X5 E70 (2007 - 2013)
    Recently, I have been noticing a loss of power/acceleration/speed. I can't get passed 40mph. A few months ago I got some codes, but the codes went a way, so I didn't think anything of it: P0430 (Catalyst System Efficiency Below Threshold, Bank 1) and P0420 (Catalyst System Efficiency Below...

    I understand there are many posts about this already and I have read all of them. I still have not found the information I am looking for. I have a 2000 BMW 328i with a clogged cat. Since I bought this car everything has gone wrong that possibly could and it's been a big PITA. I'd like to have...

    Hi guys, newbie here. Feel cheeky my first post begging for help but I promise I'll do my best to participate and help others where I can. So my issue. For about a month I've had a problem with my 325i E93. Whenever I reach 40mph I get a noise (can't describe it) that appears to be coming from...

    Hi guys, this is my first post on this and was really just looking for any advice. Just today my 2001 330i touring has managed to begin blowing at the join section of the downpipe and the cat. It's just next to the sensor and I'm unsure as to how long it will take until proper damage is done...
  9. F30 / F31 / F32 / F33 / F34 / F36 (2012 - current)
    Hi, everyone, I just found out that the N20 and N26 has different cat, so the connection to the center pipe is totally different. I got the eisenmann centerpipe which is made for N20 engine, and I wasn't able to install it on to my N26 f30. anyone know any brand that makes a center pipe for...
  10. E60 / E61 (2004 - 2010)
    my 2009 535i has bad front and back cats. We straightpiped the back ones and now the exhaust is cloudy sometimes, and it still starts up pretty rough. The exhaust guy told me to either get new front cats ($700 each) or flash the ecu and get rid of the front cats too. I'm not worried about...
  11. E46 (1999 - 2006)
    My 2000 323i has had a rough idle, horrible acceleration, at times I won't be able to get over 20 mph and I'll have to restart the engine, and it's died from having too low of RPMs while idling. The engine light doesn't come on so I don't have any codes. I've been told that this is from a bad...
  12. E39 (1997 - 2003)
    Keep pulling a EA code (catalyst efficiency below threshold cyl 4 - 6) on my Peake scanner and based upon research from all over the web, I am going to try replacing the post-cat oxygen sensor for cyl 4 - 6. The only problem is that I do not know which side of the car this sensor is on. Anyone...

    Hello, I drive BMW 2000 328i With 220k miles. About a month ago I got code P0420, dealer wanted 3k for repairs, however he said not to waste money on it because it also has an oil leak and high mileage. Anyways, i poured Lacquer Thinner in the fuel tank, to try out and clean the CAT. I drove...

  15. E39 (1997 - 2003)
    It's been about 6 months since I can say my car ran perfectly. I can't claim to be the most knowledgeable about BMW terminology or BMW's in general, which brings me to reason I've been taking everyone's opinion about whats wrong with my vehicle with no luck. I'm coming to the Bimmerfest forums...
  16. E36 (1991 - 1999)
    :eek:ok guys, I dont have use of a comp all the time so i searched quick and did not find an issue alike on this forum. My 1996 318i sedan has gotten a loud rattle recently. It rattled before but now is way louder. In gear or in neutral, it doesnt matter and pitch will stay the same. If I give...

    Hey all again... So I drive a 96 318ti. I got the valve cover gasket replaced by what I thought was a good mechanic... It was leaking oil into cylinder 2. So about 8 months now and I went in to change my spark plugs. Turns out now it's leaking into 3/4 boots!! So my question is...when replacing...

    Hey guys. So my cel popped up over the weekend that read p420 catalytic system below threshold bank 1. The guy I bought it from Supposebly put a new catalytic converter in last January. Then I bought it in April and cel came up saying the cat was bad. So I got if replaced. I then replaced the o2...

    Hi Folks, I'm a little bummed.. having spent almost $4K on suspension problems the past year replacing pretty much everything.. I now am running into engine issues. The car has 122K miles on it and I took it to a independant mechanic, here's what they are saying: "...(1) Fault Code 229: Control...
