percha

I had the same last winter, I would say this is nothing more than moisture and bacteria building up in the HVAC system. What I did to remove this # Change the cabin filters # Run the car for a long journey with full heat changing the selection of where the air is coming from using the button (windows down if too hot) # If still present then buy one of these: https://www.halfords.com/motoring/engine-oils-and-fluids/air-con/stp-auto-air-con-cleaner-150ml-149876.html (Mine didnt need this)

corrosion, by the looks of it. Probably due to pads wearing unevenly and not touching that part of the disc.

I guess next thing would be maybe water ingress somewhere or an earth issue?

@Cadwell Parker bought this one recently: https://www.ebay.co.uk/itm/Exide-EK1050-12V-105Ah-950CCA-AGM-VRLA-Start-Stop-Car-Battery-AUDI-BMW-MERCEDES/202428492292?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908131621%26meid%3D74b86af2e53441babce63057e828c103%26pid%3D100678%26rk%3D2%26rkt%3D3%26mehot%3Dnone%26sd%3D124326932591%26itm%3D202428492292%26pmt%3D0%26noa%3D1%26pg%3D2380057%26brand%3DExide&_trksid=p2380057.c100678.m3607&_trkparms=pageci%3A30f5d61c-27ea-11eb-83c8-ca9b67475d27|parentrq%3Ad048d7ce1750a4d7d12ef7c4fff525c8|iid%3A1 Although this is slightly higher rating at 950CCA

Is it on the original battery? I would be looking at the battery statistics and maybe charging that first as all of these faults look to be voltage related, but I could be wrong: Have a look on here explains about Battery Histogram to see the details of the battery and its condition.

Yep exactly right @BFleming I was just going to say the same thing.

I bought Crosland from ECP for £25. Not sure if they are active carbon or not, they look like it from link below but in the flesh they are much more white in colour than these.. https://www.eurocarparts.com/p/crosland-cabin-filter-507110368

Thanks for the link, coming from Kent I will keep this garage hire in mind if I ever wanted/needed the ramp for a full day!

Just my honest opinion, I would stay well clear of tyres that are not a premium brand. The 5er is a heavy car and plenty of torque in your 2.5 (3.0 diesel). Going into this time of year with wet roads, and temperatures dropping its just not worth it. Interested in seeing photos of the alcantara that sounds a nice upgrade! Well done on EGR valve, how many miles has yours covered?

Agreed I did the end of warranty check recently on our F21 and its piece of mind that they have seen it and checked it over. More important if you have some niggles you want sorted. They will top fluids up etc and get it up on the ramp for full check over of tyres etc and coming up to colder period this can only be a good thing. Sent from my Samsung S10+ using Tapatalk

I checked mine this morning out of curiosity on warm up time, on a mix of A and B roads, small section of dual carriageway it got to around 90degC Oil Temp (Note: Coolant Temp will be above this at this point as quicker to heat up) in 9mins. Then I assume the thermostat opened as it then stayed around 90-95degC for a further 9mins until 18mins where it was at the 100degC on the dot... I think you need to have a drive of both and also try out the 8Spd ZF Autobox as it really is nice.

It does depend, if its 10mins with some dual carriageway/motorway mine gets to temp quite quickly and would do it in 10mins just about. I be interested to drive a petrol 528i or 535i to see how they compare! Sent from my Samsung S10+ using Tapatalk

10mins drive to work, I agree a diesel will only just be warm if that.. Although you state 13k a year so you must be clocking up some miles on other trips so for me I stand by my suggestion of a 3.0d engine. Sent from my Samsung S10+ using Tapatalk

I did the same jump went from our beloved E91 (I assume you mean E91 Touring and not E93 which is a convertable isnt it?) 320d Tourer that we had from 21k to 141k and it was a great car, I went for a F11 530d Tourer Msport! You really wont look back its by far a much more competent, relaxing, enjoyable car. A real pleasure to drive, I am so pleased with mine best car I have ever owned by a long shot. Personally I would go for a the 3.0 Diesel engine, its from what I can see the most reliable and hardly any thirstier than a 2.0 Diesel, also its better matched to the car for power/comfort/ability. As others have said rear air bags, and make sure for good service details, check for water ingress in carpets/boot compartment under boot compartment. If you are keen on petrol I would drive one first, I think you would be surprised, as it would feel slower than your current 318d I believe. Its a heavy car and 2.0 petrol just hasnt got the torque.. I bought mine with 55k on the clock, and went for one with the extras I wanted. Adaptive Headlights/Xenons are amazing well worth looking out for, as others have said on the forum the standard halogens are poor. Good luck!

Coding I believe is only covered via Esys tool and not Ista. I have used Ista for reading/clearing fault codes and DIY rear air bag change to Arnott units. I am just starting to setup Esys on my laptop to use for the first time. Google is your friend for Esys downloads/info etc. Other than than that you can buy an obd connector and then purchase bimmercode.. https://www.amazon.co.uk/dp/B071D8SYXN/ref=cm_sw_r_cp_apa_i_slJFFb8NNPSW8 Sent from my Samsung S10+ using Tapatalk
