picked up used car: driveline vibration under load plus a few other niggles

Hi guys,

Recently bought a used 2017 F26 20d xdrive msport auto for my wife, really nice spec - m sport pro pack, 20" factory rims, pro nav, hk speakers, reverse camera, adaptive led's etc.. she's very happy, and so am i, mostly.

My daily is an F31 335d xdrive, so really familiar with the xdrive system and how it should feel, both cars are different drives and i love how different they both feel to drive.

Purchased as approved used from a UK BMW dealership at distance with 36k miles on the clock, comes with 1 year approved used BMW warranty. Car has full dealership service history, with both sets of brakes, tyres and major service recently carried out at the supplying dealership. I've spotted a few niggles with the car that i'm going to have investigated by my local dealership and wanted to run these past you guys:

- Car tends to slowly drift left at motorway speeds and the steering wheel sits left of centre. When straightening the wheels so the car tracks straight, steering wheel still sits 1-2 degrees left of centre. Physically straightening the steering wheel makes the car slowly drift right at motorway speeds. Car has had alloy refurbs, tyres show signs of sidewall wear so i believe the previous owner liked the kerbs. I believe a full alignment is required here? Dealer that sold me the car to pay if this 'needs' doing.

- Tailgate area rattles and squeaks - i believe there is a TSB for this, trunk needs an adjustment? Anyone know whether this would be covered by BMW warranty?

- Some of the alloys have been refurbished, centre caps are horrendously corroded, supplying dealer sending me new caps to have fitted.

- I can feel a faint shudder or vibration through the driveline which starts at around 25mph until 35mph, you can drive through it and doesnt seem present at other speeds. Same sensation present in other drive modes, eg sport, comfort. Same sensation present irrespective of gear, or revs - if i manually drop to 2nd/3rd gear the revs raise and the sensation seems to be amplified. Best way to describe what im feeling is similar to when you shift to a too-high gear, and an engine feels like its labouring, also sounds abit like an exhaust blowing. Feels more like a vibration, felt through the seat, coming from mid to rear of the car, cant feel anything through the steering wheel or pedals. Car had new tyres in the last 6 months, i thought wheel balance but then the issue goes away if i back off the throttle and coast.

Due to COVID rules right now in the UK, zero test drives are allowed prior to sale, plus it was a long distance sale so we only saw the car on the day of collection. Picked up the car on the 31st Jan, notified supplying dealer of the above issues on the 1st-2nd Feb. Salesman has already used the '.. well its passed approved used checks' line on me several times now, so i'm kinda sat here feeling abit fobbed off until i can have an unbiased oppinion at my local dealership, 2 weeks from now - the earliest i could get booked in. Considering i was told pre-sales that any car that has alloys refurbished, has its alignment checked: i don't have much hope with the rest since the car feels out of alignment. Car was quickly turned around for end of month sale, so maybe this got missed out?

I initially thought the driveline shudder was a characteristic of this engine, especially with it sitting around the 30mph mark, maybe for economy purposes with this being the 20d engine, anyone have any thoughts or experience on this? I'm naturally quite concerned about this issue, really love the car but the last thing i want to do is inherit something bad from the past owner. What i would like to know from you guys are the possible outcomes here, and what i can expect to be covered under warranty? Any bills for wear and tear would be billed to the supplying dealer, and if they cannot help i would look to explore other options: but i hope it doesnt come to this as we are otherwise happy with the car.

Recent spell of snow here in the UK, and the xdrive seems to be behaving as i'd expect from my experience in my F31: no grinds, jerks or strange behaviour, gearbox shifts smoothly also.

Sorry for the long post, any help, thoughts or things to try out would be greatly received.
