Welcome to the Forum

I was going to say battery (then read your post again) have you checked the Power Post under the bonnet is that tight?

Otherwise it is a Diagnostic session

Dave

Morning

Get the starter motor checked if you can hear whirring it sounds as though the starter is turning but not engaging

Dave

Wait until they add AI and the damn things start thinking for themselves 🤣🤣🤣  Can't wait 😂 

Enjoy your Beemer

Morning Paul

It wouldn't be a proper BMW if it didn't act weird now and then. First thought sticking starter relay ?

Dave

Morning Alex

Welcome to the Forum

Oo er never really thought about this before

Try looking at www.realoem.com in the trim section (I think) it may help or Pictures of an M135 for clues 

You could also ask BMW Customer Services or a really good Body Shop

Sorry that's all I can think of

Dave

Well Done Rory

My E53 still doesn't but I am used to it now 😂

Hi Steve 

I wouldn't think so. the low pressure pump in the tank should push fuel through to the high pressure pump which should be self bleeding

Dave

Morning Jack

Not sure why you posted in 2 sections Sadly the advice is the same 

First you say it's not turning over ? Is the starter motor turning the engine over but not starting ?

Second When you look through the oil cap you wouldn't see the Timing chain as they are at the rear of your engine

Third You say you had a replacement engine fitted 14 months ago what condition was it in/where did it come from

Your engine has an upper and lower timing chain to change both is an engine out job so major work. If either chain is broken and the engine turned over damage will be caused to the cylinder head

If you are not capable of doing it yourself then you need the help of a good Garage

Swapping from RF to normal tyres is common, personally I always found the Pirellis wear quickly loads of grip but need changing more often I have Hankooks on both my X5's  

As the Adblue contributes to emission control I am not sure if that would give issues at MOT time or not. As for the ECU upgrade ask how many they have done on your engine maybe? My brother inlaw is on his 5th 5 series estate all have been 3ltr diesels all have been chipped from after their 1st service. all cars have been serviced by BMW all his cars are run to around 150k (he has a business in Holland) the current one showed just under 400bhp on a rolling road all have been reliable mechanically 

Good Luck it is about enjoying your car by personalising it 

Dave

When looking at BMW 1.4.0 any Greyed out modules mean no communication  so need investigation

The ABS module can be removed and often repaired I have used ECU Testing in Nottingham a few times they are normally fast turnaround as well worth talking to them.

Dave

Morning Kevin

Welcome to the Forum

Not seen this on a petrol model yet seen quite a few diesel though, as your car is only 4 years old unless it has covered more miles than the star ship Enterprise a blocked DPF/Cat is unlikely.

A diagnostic session should find the culprit quickly, my guess would be a sensor gone wrong. If you don't have your own diagnostics a good garage with a BMW capable system can do it. Or if you have an extended Warranty with BMW use them

The Differential Pressure sensor  sits on top of the DPF/Cat so should be fairly easy to reach

Hope this helps

Dave

Tyres are an emotive subject as they are all to often chosen by price yet they are the only thing between us and the road. Steering, braking and comfort in all weathers a lot more than a round black thing. What is on the car now are you happy with them ?

You are going to notice the extra power so get your wallet ready for extra visits to the pumps 🤣

Enjoy 

Dave

Morning Chris

Good plan, check www.realoem.com for part numbers that will fit your model

They aren't wired together (or shouldn't be) but they will be linked through the Footwell Control Module (FCM) or may be the  Junction Box Module (realoem again) 

Dave

Hi Eddy

Welcome back to the Forum

Very pretty ENJOY

Dave

Morning Rory

Welcome to the Forum

My X5 4.6is had the same issue in 2003 (my door is Hormann and rolling code) I eventually talked to a neighbour who works for BMW (not a dealership) he told me BMW actuators can't handle rolling codes I would have to change the actual door motor ??? 

Needless to say I kept a Fob in the car and still do with my current E70

Dave

Hope it's back with you quickly and you get to drive it again soon

Dave

Just one thing it would look a lot smarter if it was parked away from the skips 😂

Hi George

Welcome to the Forum

This is a new one 

Try Googling The Register of BMW Specialists there should be one close by that can help

Dave

Hi Both

Welcome to the Forum

Drive it and Enjoy it 😁

Dave

Morning George

Welcome to the Forum

If you have the original can it be repaired ? In the UK Companies like Cartronix and ECU Testing might be able to help or maybe the Salvage guys like Quarry Motors

I did read about someone buying from Turner Motorsport in the USA worth a contact to see if they can help

Good Luck

Dave

As the CD sounds like it is trying to do some thing try Disconnecting it, like wise the stop start button. Do it one at a time to see if one effects the other

If your charging the battery don't do it at the battery unless the battery is disconnected, use the charge/jump points under the Bonnet/Hood

Errr obviously to change the Sub Frame all components attached to it need unbolting the engine needs supporting engine mounts undone any other components attached to the Sub Frame will need Support from above.

Take a look at www.realoem.com the exploded drawings are small but very useful to understand what goes where

Dave

Morning John

Welcome to the Forum

What makes you so sure it is EGR related ?

If it is in fact EGR related the Complete EGR system needs cleaning and checking or replacing to ensure that it is working as it should. The DPF and its sensors also needs checking 

If the Garage just diagnosed the fault and reset the code it hasn't fixed the issue 

Dave

Morning Richard 

Depends where the job is carried out if you can get access to a ramp then not to bad, if you are doing it on the drive then doable but the Faff factor increases 

Good Luck 

Dave
