Hi Steve That will teach you to go upgrading stuff !!! In answer to your question Yes you have to go through the pairing process again. Normally press the pairing button and hold it for 3 secs while holding it put the key in the ignition and turn it on after 5 to 10 secs release the pairing button and you should see Bluetooth Pairing in the display, then search with your shiny new phone and enter the code. If not you can use BMW 1.4.0 or INPA to force pairing. Remember your ULF can only pair with 4 phones when its memory is full you will need to clear it to be able to add another. Dave

If your engine is an early version (pre 2001) the part number on the Cam sensor should read 12141703221 or 12141730028 as far as I can tell. If the o2 sensor wiring is missing then the DME will be confused on mixture settings so may have a "limp mode" setting I don't know if that can be over ridden or over written to give you performance back. As said in earlier posts 160/170 bhp in a stripped out shell should feel pretty lively just another thought the CAT isn't clogged is it?

The codes you keep quoting are not BMW part numbers I assume they are Seimens codes but cant be sure. Have you looked at the Seimens site to see which models they were used in and how friendly they are to use? As an example I know from previous experience that often a DME needs a code entered to match engine gearbox controllers? Here's a thought that should have occurred earlier, early cars used a Cam sensor which produced a sine wave signal for the DME later cars used a Hall Effect sensor I believe the DME will assume the sensor is in fault and not advance which would explain your lack of performance.

Frustrating aren't they ? BMW firmly believe if it isn't there when they look it can't exist? My X5 hates wet weather always has the sensors go on strike in the wet or after a car wash but I can turn mine off and just use the reverse camera. I assume when you are driving in heavy spray or rain that triggers them?

Looking at your pictures you show only part of the label the number on the right I think is the part number Just took a quick look Basic DME was available for E36 E39 E38 and Z3 between 1994 and 2001 part number key 1241429999 if you check realoem and click on the part number you will see all the compatible part numbers. Do the same for the Programmed and it seems they were more specific only being available on the E36. That is always assuming that your engine actually came from and E36 of that vintage and not something newer??

Then check www.realoem.com E36 323 you will be able to find engine numbers and DME numbers then double click the part number and you will see what other models they were used in Then at least you have a starting point at the moment you are going in circles guessing

Check www.realoem.com it is a BMW parts list put the last 7 digits of your chassis number in the search box it will bring up your model Then get the part numbers and compare them to what you have. You will be able to see if (a) they are compatible with what you have

From memory there were 2 types of DME, a programmed DME and a basic DME. Worse I am not sure if they are the same manufacturer have you checked www.realoem.com Dave

My own BMW is a petrol version so my diesel experience is limited to my family members My brother inlaw currently runs a 530d he commutes in to Europe for work and this car is approaching 300k his previous car a 525d went way beyond that, before the BMW's were a succession of Merc's. His service regime is meticulous with oil changes every 5k and the full BMW schedule followed as indicated plus gearbox services in line with ZF's recommendations. Yes he has had niggles particularly things which BMW seem to ignore/deny/can't find or see mainly electrical, these we have fixed ourselves but mechanically the cars are mega. So History History history plus general condition always a goo indication that someone has cared. ZF recommend gearbox service every 60/80k BMW say sealed for life, for life read end of BMW warranty responsibility. Engine bay should be clean showing no signs of leaks. There was a problem with the tubular exhaust manifolds cracking (smell of exhaust fumes in the car) BMW solution was weld it up which proved temporary we found a cast manifold on the well known auction site which strangely was cheaper than the tubular manifold fitted, problem fixed for good. Both his cars have been remapped with no issues and the current one no DPF issues either. Suspension bushes last about 80k but are not difficult to change/up grade just make sure you have a full suspension alignment at each tyre change or suspension work to protect tyre life. Make sure all switches and gadgets work as they should.

Result Rob Well done good information for other 3 series owners, I know very well about horse/cow/sheep muck sometimes when it's dry it feels like you need a chisel to get it off Dave

Morning Alex Welcome to the Forum Reading your title you say your car is 2019, how ever E92 I thought stopped manufacture in 2013? When you say you took it back to a Garage is this a garage you just purchased from? If the car is 2019 reg then it is under Warranty and should go to a BMW Dealer, Even if it is recently purchased 2013 reg the selling garage should repair FOC as the seat belts and operating system are safety items. If someone has pulled the arm out it may be the system needs resetting if the garage are just car sales they may not have the knowledge/skill or tools to do the job. Dave

I can only think to look at Ebay and similar sites to see what is available as a guide? you may even be able to find an engine that may make an economical repair possible, depends how much you liked the car?

The only things left are Fuel pressure, (pump filter and regulator) MAF and Throttle body if they are working correctly then I am running out of ideas?

If playing BMW gets stressful or boring I put a Dynavin unit in my 4.4 X5 some years ago the unit was brilliant and I covered the cost by selling the redundant BMW units. Check them out

Aren't modern cars amazing in their ability to frustrate us. As you say quite probably something simple have a look at BMW Vindecoder it should bring up the build sheet for your car that will tell you for sure. Dave Let us know what it is as I am in my 70's and BMW and Mercedes haven't been able to defeat me yet (they have both tried hard and even come close) with the help from the Forums we will win.

Compression is good by those numbers so 1 off the list. O2 sensor signal or lack of will certainly not help as the DME can't set the fuel air ratio accurately. There should be 2 sensors 1 up stream of the Cat the other down stream they also need to be correct as their rating voltage/signal is different. I don't know about the E36 but often the cable length will be different to make sure they are in the correct place, unless of course someone has changed one for one of the "universal" ones ?? From memory the O2 sensor also retards ignition at tick over to maintain exhaust temp so a failed system could well be the cause. Dave

Morning Larry I take it the faults you are seeing are displayed on the I-drive screen, you really need the codes read by someone with the right software they will also be able to reset the triggered codes. You need a garage with Autologic or BMW software to be able to check and reset everything plus identify the issue, you could try disconnecting the battery for 1/2 an hour to reset everything also make sure it is fully charged (your cars equivalent of the computer turn it off fix) I would avoid driving the car as each trip could cause damage due to having no suspension at all. Dave

OK Dan not the end of the world if you have a charging cradle the phone still needs to connect somehow, when I look at the picture of your phone charging cradle the button at the bottom of the picture looks just like the pairing button in my X5. So try this "press and hold the button for a couple seconds before turning on the ignition, continue to hold the button for around 5 seconds" or try the "voice" how_to_BMWTele1series.pdfhow_to_BMWTele1series.pdf button on the steering wheel if it works like the X5 then "Bluetooth Pairing" will come up on the radio display then follow the instructions on your phone screen. Somewhere in your book pack you may have a card or note with a pairing code You can also change the charging cradle for not a lot of money I have had,Motorola, HTC, Samsung, I phone 3 and Nokia in the X5. I would search on Ebay if you want the cradle if not there should be instructions for pairing somewhere. Is there a button with a phone symbol on it on the radio right hand side? Just tried uploading instructions I found the upload failed so try this https://www.babybmw.net/forum/howtos/how_to_BMWTele1.pdf

Top Man👍

Hi Steve Welcome to the Forum I would guess it is one of the horn units that have either failed or are disconnected. Here are a couple of websites to help you find your way around. www.realoem.com a BMW online parts list to make sure you have the correct parts if replacing stuff, just put the last 7 digits of your Vin number in the search box. www.newtis.info BMW Technical Information site same information that BMW Dealers work with. www.pelicanparts.com this one's an American site but great how too's with step by step pictures just the steering wheel on the wrong side. Enjoy your squeaky Beemer Dave

Morning Matt Welcome to the Forum Take a look at www.newtis.info it is a BMW Technical Information site, the same information as BMW Dealers use you should be able to find an answer there. You could also try www.pelicanparts.com it is an American site so steering wheel on the wrong side but good information and how too's with step by step pictures. For parts information www.realoem.com just put the last 7 digits of your Vin in the search box and it will bring up your model. Hope these help Dave

That's what doesn't make sense as I said even in standard form and a stripped out shell it should go quite well. May be he ran out time/money with sorting the motor?? First step compression test then fuel pressure if they are OK. DME, MAF, and Throttle Body. Dave

Sorry James but whoever you brought it from sold it for a reason? Which is probably the power issue you are suffering? Did he compete successfully?. The original 4 pot with a simple remap is capable of 130 to 150bhp the 323 should give 160 to 180bhp in a stripped out shell either should feel pretty punchy. So something is strangling the engine and not allowing it to give it's best, as I said in my previous post I think fuel pressure needs checking as does all the other stuff. Check www.realoem.com it's BMW online parts list I would look at the original 1.6 or 1.8 1 series engine parts if you have the Vin number put the last 7 digits in the search box it will bring up the original model. Get the part numbers for the DME and fuel pump and check against what you have in the car The BMW DME will also take input from the Gearbox controller, ABS unit plus others. When I look at my X5 with my BMW 1.4.0 software I get 3 pages of control units that are scanned with 10 control units to a page each control unit can be interrogated.

Morning Dan From the pictures you have the Professional CD setup and I don't see a Bluetooth symbol in the display? Can you select Aux then scroll through to see if there are options under the Aux connection (guessing now). Also try searching with your phone as my phone could find the ULF in my X5 but could only connect when the ULF was in pairing mode. Some of the systems used the aux/usb connection in the center console to connect phones/external devices. Check realoem it should tell you what is fitted to your car. The BMW system will record all faults as they occur and retain them in the memory, as an example with BMW 1.4.0 if I scan and get an Error message I will see a red marker Error present with a description of the error, or a yellow marker error not present (so intermittent) with a description so I know where to check. After scanning and repair if I clear the recorded codes it should clear all I have read that Carly for BMW an App for you mobile is OK however it is a subscription App so annual fees, me being a tight old git I paid for BMW 1.4.0 and have it on an old laptop I use in the garage. What ever you settle on you will find it invaluable and it can save a fortune in the long run. Dave

Morning Scott 3 or 4 years ago travelling at around 40mph suddenly no drive, no noises bangs or bumps parked and called the AA who using snapon came up with the same fault. Their diagnosis gearbox? Got recovered and like you selector showed all gears Drive Reverse Manual and Sport modes turned out to be rear diff failure. Sadly not that rare with the 3.91 diffs, if the diff is sound I would contact a ZF specialist who can read the internal box codes from the mechtronic unit. Dave
