Morning John Karl

For me that would indicate either an ABS sensor is down or the ABS controller has a Fault (not unknown)

There are several companies that repair the ABS controllers at a reasonable cost and Warranty their work, the controller can be removed without disturbing the Brakes. An ABS sensor is around £20 make sure the reluctor ring is clean and not filled with crud (seen that a few times) fiddly to clean but worth it. Google will help with test procedures for ABS Sensors

Don't know what system you brought locally but it seems to have moved you forward so Good Buy

Brilliant information and that you actually got there, Why oh Why do they make it such hard work for the Customer !!!

When towing in the UK we are restricted to a Max 60 on Dual carriageways and Motorways. When towing I pull a Horse Trailer with a couple of fat horses on board and touch wood never had an issue.

Enjoy your Beemer and Winnebago

Oh dear !! Sounds like Trans Fail Safe has been triggered

Causes could be Low Trans Fluid could be a Solenoid sticking could Torque converter related could be a Mechatronics unit issue

ZF who make the transmission in your car recommend service at 60 to 100k so due by your mileage. 

Find a good Trans Specialist they should be able to scan the box update the software and service it (just make sure they use the correct ZF Longlife Fluid

As a comparison my E53 4.6is with Dinan cams and throttle body (400 + hp) is on 164k it gets a hard life when it's driven and is smooth even under hard acceleration but has been serviced (last one flush as well)

Hi John Karl

Welcome to the Forum

First the 4x4 light can be triggered by several things, Low Battery voltage, ABS sensor faults, Steering angle sensor. However the fact it is combined with Trans Fail Safe which locks the transmission in 3rd  is more of a concern. I would carry out a Diagnostic Scan (as you seem to have a collection hopefully you have a BMW capable scanner) Clear down any codes then rescan to see what if anything comes back. The Red Tyre symbol is tyre pressure the E53 used the ABS system to measure rotation a flat tyre will rotate at a different rate and trigger the warning. With luck replacing a failed ABS sensor will sort the problem. Check Google for ABS sensor tests 

You don't say how many miles are on the car or whether there is any evidence of transmission services being carried out. I would change the fluid and filter as a matter of course, which hopefully will get you back running properly if not you may need a Transmission specialist to help which could get expensive

Fingers crossed its the simple fix

Dave

Yay well done Alex

Like I said our "Go to man for Diesels)

Now you can enjoy your Beemer again

Davve

Glad it worked 😃 Try (if you aren't already) www.realoem.com for BMW parts numbers some times it takes a visual search of the sections as I don't think it would find Gizmo 🤣

Welcome to the Forum

I believe they call that a buffer stop BMW used them on several models so should not be that hard to find.

One of our Z3/4 drivers may be along to confirm 

Hope this helps your search 

Dave

Damn Smarty !!

Fingers crossed for you Alex 

Hi John

I am not aware of Right Connections worth a Google search to see if their kits are "Universal" or Specific to a model

The local Company I used (Tanfield Towbars) ordered in the Oris kit for the X5 and it came with the loom complete It just needed plugging into the PDC controller and registering to the chassis.

If the trailer plug is connected to the car the rear PDC is disconnected but the rear view camera is still in use. 

I would think any competent Towbar Specialist would know how it all goes together and how it should work

Dave

You will become our go to man for Diesel fuel systems 🤣🤣

Fuel pressure sensor on the HPFP is just about all that is left

Welcome to the Forum

If your car didn't have Bilstien as OEM it will not accept the inserts

Start with www.realoem.com put the last 7 digits of your Vin into the search box it will bring up your Model.

Then search the relevant sections the small exploded drawings are useful for identifying where stuff fits and how and the part numbers are good for Googling the best source/price etc. If you double click the part number it will bring up any alternatives/models parts were used on.

Good Luck

Dave

Rants are part of the analysis process ( normally with me it ends with "how did I miss that) so Rant on matey 😅 You are  probably on the money with one of the New parts having a fault. 

One of our sons friend had a problem that was down to the "O" ring seal on the fuel rail pressure sensor. The sensor was new and was fitted by a Garage that had carried out the work similar to yours, car started fine was driven home and sat on his drive for a coupe of days then wouldn't start ?? The Garage due to pressure of work couldn't help for a few days that's when our son volunteered me. We started at the tank and filter and we worked our way forward it was when checking the fuel rail pressure sensor we found a small crack/split in the "O" ring it was enough to not let rail pressure reach and hold sufficient pressure The Garage supplied him a new sensor (FOC) we fitted it and after around a dozen or so cranks it fired up and touch wood is still running OK. His Garage had never seen it before nor had I and personally wouldn't have suspected such a tiny split could be the cause.

Hope you find it soon

Welcome to the Forum

I fear that BMW is your only route with such a new vehicle 

BMW stopped access to www.realoem.com from 2019 year on making life increasingly difficult for anyone who wants to make changes or upgrades.

Good Luck

Welcome to the Forum

BMW OEM fitment is I believe Oris or Westfailia so an after market fitting from either company should be OK as the loom is pre-designed to be plug and play (no hacking into the cars loom) 

My E53 X5 came with a Westfailia removable tow bar from new, my E70 3.0d has an Oris removable tow bar fitted by a Local tow bar specialist no problems or issues with any electrics.

Dave

Morning Alex

Welcome to the Forum

I would start with a careful back track of all work carried out a PITA I know but the only way to be certain each part is OK. Run fuel off after the filter through a Coffee filter paper that will show any metallic swarf if there is any (fingers crossed) Check the rail pressure sensor "O" ring I have seen one with a split that was causing similar issues to those you are getting

I believe there is a Bleed sequence in ISTA (never had to use it myself) has that been followed?

Still a diesel virgin myself so feeling my way here

Welcome to the Forum

Good to have a fellow Tinkerer on board

Dave

Just spoke with my Brother-inlaw he has a 540 Touring apparently his is stuck to the Headlining using a double sided sticky pad saves touching the tailgate trim and works really well.

Dave

Oh my Lordy Lordy

Take a look at www.realoem.com either search by model or put the last 7 digits of your Vin into the search box it should bring up your model. Then look at the trim section there are small exploded drawings that should help even if it is an earlier model fixing will be very similar

As far as I am aware the roof liner is a preformed section that is held in place by trim clips and screws at the grab handles, it is on my X5 anyway (I assume you have the Panoramic Roof not that it makes any difference) 

The Auto electrician quote is probably for 1 or 2 hrs work and seems reasonable. My experience of Halfords is "Good for Parts" but that's it. BMW like most Manufacturers have things designed for Production line assembly not necessarily for being worked on often on modern cars whole sub assemblies have to come off to gain access ???

I have a friend who has a Mercedes SL he settled for a combined Front/rear camera that sits by the mirror and seems to work well.

Welcome to the Forum

As it is less than 3 years old have you tried the Dealer it should be tight and quiet? Obvious thing ask a passenger to place a finger on the dash/lid around the Glove box to see if that effects the rattle. At least you will know where it comes from. I take it the glove box is empty ? be embarrassing to have a dealer empty it and stop the rattle 😁

Dave

Morning Sue 

Welcome to the Forum

Sadly Halfords staff are not the best trained or knowledgeable lucky he didn't drill holes

What you need is a set of trim removal tools and some patience, on the tail gate the upper trim panel I would remove then there are trim panels on the hinges (you only need one side I would say passenger side) The roof liner will need freeing up at the rear, now you should be able to feed the camera lead through from the tailgate to the headlining. Replace the tailgate trims and start working along the side of the car above the doors take off the grab handles and pull down the rubber door seals you should find enough room to feed the cable along the edge inside the Headliner to the front. Nice and neat out of site and no holes, time wise I would allow 2 or 3hrs with tea and biscuit breaks. A decent Auto electrician would I guess take about the same maybe quicker as they do it more often.

If you can't DIY then look for a good local garage or auto electrician (their rates will be way less the BMW)

Google fitting the camera see what comes up you never know someone may have posted a video

Good Luck

Welcome to the Forum

Normally with aftermarket Head units there will be a Canbus interface that plugs in to allow all in car controls to work as normal

I would guess either the Canbus interface hasn't been fitted or is at fault have you tried contacting the Manufacturer to see if they can offer advice ? Installation manual for example that may give clues.

Good Luck

Dave

Sorry Tony 

Can't find much to help other than the sounder should be clipped into the kick panel in the drivers footwell there should be a plug on top. 

Try unplugging one of the plugs on the PDC control unit in the boot (one front one rear) If you get one end working it may help narrow it down.

Dave

Morning Mehmet

Sometimes when confidence goes in a car moving on is the best thing 

Good luck with whatever you decide after all we get cars to enjoy not stress us out

Dave

Have you had a Diagnostic scan using a BMW capable scanner? Check the ignition switch and circuit. I take it the "Display" is the cars screen ? 

Dave

👍👍😁 Well done Mick
