So, Aston gone but not forgotten (journal here) https://www.pistonheads.com/gassing/topic.asp?h=0&... plan was to be really diligent, get rid of all the left over bits, finish the e36, sell that, then make a move with a clean budget and a space in the shed.



I have poor self control and no sooner had one gone than the need for the dopamine hit started to make me tweak pretty badly, scrolling autotrader like a crackhead eyeing up a back alley dealer.



So, following on from the Aston martin which everyone was convinced would be horribly unreliable i bought a Mclaren, which everyone has told me will be horribly unreliable.



Purchase process was a disaster with the bank missing a payment cutoff meaning i ended up staying in a best western in Derby for a weekend.



Anyway, its landed







Almost certainly wont be getting a half cage or buckets in this one, and in no way have i already ordered a full set of Pagid RSL2's


Bit of an odd car, individual paint (black roof with "elite" silver (3 stange silver looks very spangly in the flesh but like all other silvers in pictures) brown and suede interior, carbon most things (splitter/blades/diffuser/interior/engine/rear clam) but has also had a load of post manufacture upgrades like soft close doors IRIS2 etc etc.


Needless to say at 620hp and 1350 KG its banana's fast, however in usual "super car" fashion the front tyres are from 2016 so its going no where fast until those are in the bin.


Discs are a bit lipped, i think it may need a couple of bushings in the front control arms, radio antenna seems a bit meh so it will be in bits on my drive pretty shortly, oh and i suspect it could do with a pair of rear accumulators, and of course the "big" 40k mile service is looming, as is the annual one in 88 days.


Probably be fine though right? i mean the doors go up in the air so it will be fine...


Currently amassing a fortune (almost literally) in oils and parts, with a list that looks like:

Blimey that's a big list but getting it all sorted (Service wise) straight after purchase is my preferred approach too

Air Filter £200 that's a serious amount of coin - WTAF indeed yikes

Quick Google - no idea if that's the right part

https://www.thorneymotorsport.co.uk/product/mclare...

Seems more reasonable at £54.60 each even if you do need two

Yep that's the part, still ends up at 130 with vat and shipping, have ordered a pair of stock 4.3 aston ones as i think they may be a viable option, if not will have to bit the bullet and either pop some ramair ones in or get those from thorney .......

Smart colour combo. This the ex BayTree car? Could you not have got the dealer to address some of the items on that list?

Money knocked off for front tyres and discs, occupancy sensor is a recent issue, need to figure out what this is, and yes that may be a conversation given the apparent unavailability of the sensor bolts leading to a 4 figure repair potential.


Rest of it is all servicing, car has 37k on it, as far as i am concerned that means it needs everything doing, and doing correctly. I am a big believer in over maintain and under repair. there is also the fact that if i do it, it will actually be done, and with some attention.

That looks fantastic, especially the interior. thumbup

At least the brake discs look pretty reasonably priced!

Ah, dont be fooled, those are good used ones, the pads are also "used" as in been out of the box. the pads would otherwise be 800 and no idea on the discs.

Ultimately i will likely replace them with something from reyland as drilled will be a crackfest in time

That's a dose of reality!

Last paragraph is spot on. I’d rather have money knocked off, or in the form of a dealer contribution; and have any work done myself, to my exact standards.

Sounds like a sensor for if anyone is sitting in the seat or not. If nobody is in the passenger seat the airbags that side might be programmed not to deploy. When I had the same issue in a BMW I just got a resistor to replicate someone in the seat at all times and then one to show the seatbelt was buckled to stop that warning. Its not ideal but it is safe and saves a 4 figure repair bill for something that is likely to go wrong again in the future.

I really wish you were correct here, as it is your sort of right, but unfortunately the usual route is not an easy option. the older seats use 4 load sensing bolts, why 4, fking no idea. anyway one will be on the fritz, which one? dont know you need 2k's worth of MDS to know that via the obd port. if i bypass one it will always be wrong vs the other 3 "bolts"

The revised mclaren part is to remove all of that, fit an occupancy pad with a new controller, program the car. 4/5k

Old bolts are NLA.

I will sort something out, just not sure what yet......

Surely the dealer needs to sort this for you ? They don’t get out of their obligations just because they gave you money for brakes etc .

Quite probably, however my location makes that expensive and problematic for me in its own right, also, I have little faith that it won't go round and round. The car has failed an mot on this in the past, my bet is a reset will clear it, but only in the short term. So back and forth I may well go

Are those bolts specific/unique to McLaren? I bet there's an alternative if you can find the spec... (hope springs eternal etc)

Seems to be mclaren specific sadly, but I suspect it's acrually the connection side of the pressure transducer that's failing so it maybe repairable. I just need to consider what I am going to do as there are a number of other niggling issues that may all end up being expensive. I can sort them all if I need to, or believe I can, but I shouldn't have to really given that it's a dealer supplied car. However it's a massive pain in the arse to return it.

I'd rather take the pain now with the dealer, than fight the car for a few months and lose any goodwill from the dealer.

Faff or not, worth considering IMO.

If you’ve got that many issues get them to pick the bloody thing up! Either that,or I’m sure they’ll be a covered transport service you can go halves with them on as a compromise.
I’d be spitting feathers by now as it’s obvious they haven’t prepped or road tested if properly.

Load sensing bolts - what a great engineering solution for a problem already solved in a far simpler way…..

Assume it’s not needed for drivers seat?

Does the load sensor issue mean that the airbag light is on? If so, isn’t that an MoT fail?
