Newbie Just bought e53 2004 3.0d PLEASE HELP

[Shah89]

Hi all I have just taken the step to buying an x after selling my E46 M3 (am a cutter) after arrival of my little daughter. However it's not started great. Visited a dealer based in West Dayton and picked up a X5 with 116000 on the clock and 2 previous owners. The car was advertised as Immaculate but on my arrival home and a visit to my local Indy it seems that the Blower motor needs changing as no heat or A/C working and also there is no EML on startup which means it's been deleted in some way. I am thinking to take legal proceedings against the dealer as they have refused a refund even though a customer is legally entitled to one under the "Consumers Act 2015" which gives customers a 30day refund if the product is not fit for purpose or not as advertised. I know this can be a lengthy and expensive process (small claims court). Wondering how much I'm looking at if I was to tackle the problems and get a new blower motor and sort out missing EML. After running scan there were a few fault codes:

Chassis- Electronic Height Control
02 Right level sensor

VTG- Transfer Case
52D4 Incremental sensor/Faulty Signal/Intermittent

54C6 Oil deterioration/Signal too high/Permanent

EGS-Automatic Transmission
4E8701 Unknown fault
514208 Unknown fault

Climate Control
0A-- AUC Sensor/Short Circuit to positive/Permanent
32-- Parking/ extra heater/ open cicuit/ permanent
A0- unknown fault

Instrument cluster
BD-- Electronic braking force distribution
BF-- internal fault
00-- unknown fault code

DSC
5EB1-- power supply steering angle sensor

M57D30 DDE 5.0
4203 glowplug pre-operation
4501 MAF controlled EGR system, EGR flow too high
4242 glow plug cylinder 4 activation
4252 glow plug cylinder 5 activation
4262 glow plug cylinder 6 activation
4212 glow plug cylinder 1 activation
4222 glow plug cylinder 2 activation
4232 glow plug cylinder 3 activation

Central body STH
02 combustion air blower
30 unknown fault code
0D Flame interruption, gone out during heating operation, short circuit to ground.

I would really appreciate if anyone e could she'd some light on this as I'm really worried and my wife is really having a go   
Also if anyone knows a good Indy for the X5. Thanks guys

If it were me I wouldn't spend a penny on it.....or do any work on it.

If not as decribed & also that all faults present should have been rectified prior to sale.

I would send formal letter to seller outlining all faults stating you will initiate legal action. Consider this but edit for impact and outline your intentions if they do not act.

I would seek case specific advice from trading standards with a vew to court action.

I would not drive it so as not to increase mileage or infer acceptance.

I would probably park it outside the sellers premises with vinyl lettering on pannels listing faults and seller response.

I suggest you do not name the trader on here if asked as content here could compromise your legal position.

I will stop short of offering detailed relationship advice, but some would argue honesty is best policy....even if a brief storm follows.
