I have a 2006 325i with the N52B25 218hp engine, manual gearbox. Symptoms are generic (loss of power throughout the rev.range, stuttering at low RPM/full throttle, high fuel consumption). Sometimes I get error codes - cyl. 4, 5 and 6 misfire. I could also find out, that the problem is that the...

Advice? N53 on 2007 E61 LCI 523i - EML light on - High & low fuel pressure errors & lambda sensor/probe warnings? Looking for advice on the most likely cause of this EML light. My 2007 E61 LCI manual with N53 engine has covered 199k km (123k miles) The EML came on a few days ago on...

Hi, I know there are a lot of threads about similar problems but can't quite work out what is going on with mine 320i. When car was bought in Jan 2018 it started running rough shortly after purchase. Changed Coils, Spark Plugs, had it serviced, new fuel pump, new low pressure fuel sensor...

I had an engine warning light on my e46 had it code read it said bank 1 and bank 2 to lean so had both lambda sensors changed £250 fitted still getting engine warning light bank 1 and bank 2 lean and on tick over at lights and parking up the revs going up and down i know they were fitted my pal...

My GF has a 1 series E87 2010 and when it gets warm the engine warning light comes on. We have checked the codes and it has also been into the garage, looks like the lambda / nox sensor needs replacing and they have quoted £550. Has anyone ever done this themselves? from what I can gather...

Hi guy, hopefully you guys can give me a bit of a brainstorm on this issue. I've had the car about 8 months, it's always averaged about 15/16mpg on a 10+ mile run, but I've always overlooked it as an old 6cyl that drinks fuel. So this weekend I finished up some suspension work etc and thought...

Hi all, as says above, just fitted 2 new sensors. I was getting bad jerky acceleration between 1-2 thousand revs, which kicked in when car heated up, and other posts seemed to point to these 2 sensors. Fitted them yesterday, and now, when i start the car and ticking over, every 5 secons there...

Wanted e38 Exhaust downpipes with cats and lambda probes must be from anything v8 engine Wanted for a 750 but 740 system would be fine as I will be welding them into the original system as mine were cut out and stollen. Many thanks James 07977 502097

Hi, I had a break in my lambda sensor probe wire which caused the 30A fuse in the DME fuse holder under the hood to blow. However, after replacing the fuse and the lambda sensor probe for new, I am getting: “4205 - Lambda Sensor Heating - Short Circuit to B+” Before I changed the fuse, the...

Hi, I have a couple of fault codes that are Lambda related, they are as follows: Fault: Lambda probe signal virtual ground Code: 0041F6 Fault: Lambda probe signal Nernst Code: 0041D6 Do these codes mean the Lambda sensor is dead? Is there anyway I can check the Lambda sensor? I believe that...

Do you know if the front and rear O2 sensors are identical apart from the length of the wire on a 2004 E46 petrol? ie can they be interchanged? I am specifically asking about the 5 wire version. I have a spare rear sensor and I intend to fit it to the front (before cat convertor).

Hello fellow BMW people, can anybody help with some experience please? My 325 has thrown this fault & l could do with knowing which one works from the vast array for sale ranging from £10 to over £100. Assume anything Chinese will work as well as the reversing sensors they keep sending ! Thanks...

Hi all, I've got fault codes 2C3D and 2C7F on my 07 120i (N43 engine). Had a quick look at the pre cat Lambda locations and access seems limited-nil. Has anyone changed one of these out before? Any helpful info would be very much appreciated.

I have a dead post cat Lambda sensor. I have had a look and, as expected, it looks ceased. I have sprayed WD40 on it and let it soak a few times. I have read a few posts around the web about heating it up, smacking it hard, cutting the cable and get a deep socket over it, etc. I would...

A few years back one of the four lambda sensors started to sulk about being old. Every so often it would spit its dummy out and throw up the mil. Code reads showed it to be bank B after the cat. For those that dont know, bank a is the first three cylinders manifold, with bank b the rear 3...

Hi, Ive recently acquired an e36 softtop with an issue where it wouldn't rev properly and wouldn't get over approximately 30 mph although there were no faults showing on the ECU. ive found this to be a collapsed catalyst. Ive not had chance to properly get under the car for a proper look yet...

I took out a stubborn rusted O2 sensor on my 316i yesterday so I thought I'd pass on how I did it. I could see it was going to be a problem. I could have cut the wires and used a ring spanner and hammer since I was fitting a brand new verified Bosch sensor afterwards. However, in spite of its...

Evening All. Car drives fine.. but keep getting a 447B error. After clearing it comes back after a day or two. No warning lights or obvious problems. I've connected INPA and got a load of german for the error which badly translated says: Oxygen concentration implausibly low (in thrust...
