E85 E86 Z4M Pre / Post Purchase Inspection (PPI)

This can be known as 3 things:

Pre Purchase Inspection:
An inspection before the vehicle is purchased (either the seller or buyer can arrange/pay).

Post Purchase Inspection
An inspection after the vehicle is purchased (always the buyer arranges/pays).

Pre Sale Inspection
An inspection before the vehicle is sold (always the seller arranges/pays).

At Redish Motorsport all these 3 names (above) include the same amount of detailed work.
Here is a video showing the type of checks we carry out on a PPI - albeit an E46 M3 example:


Your situation:

If you're buying (or selling) an E85 E86 Z4M you're likely to be asking (or be asked) some questions relating to the 'common issues'

  • Conrod Bearings
  • Vanos
  • Headgasket
  • Roof Drains (E85 Convertible only)

We check these common issues to the best of our knowledge using our BMW Main Dealer training, and years worth of repairing Z4M's as our YouTube Channel shows.


Introduction:

The Redish Motorsport E85 E86 Z4M PPI is split into 5 parts:

  • Roadtest
  • Initial Paperwork/Mileage/History/Credentials/HPI checks
  • Comprehensive Vehicle Inspection (including Engine Bay & Interior)
  • Paint & Bodywork Inspections
  • Conrod Bearings, Vanos, Headgasket, Roof Drain Checks



Roadtest:
We carry out a 12 mile fully-insured road test on varying roads taking in a mixture of slow urban traffic, mid range dual carriageway, higher speed dual carriageway, a B-road ascent and finally B-road descent.


Initial Paperwork/Mileage/History/Credentials/HPI Checks:
We check through the paperwork provided with the car (Service Book, original Book Pack with Instruction Manuals etc), then cross reference the Mileage stored with VOSA via Historic MOT data as well as check the mileage is matched in the Vehicle Dash, Engine ECU, and Light Control Module.

Then we check through History records and Invoices provided with the car.
We search through historic online records to check any of the previous registration numbers to see if there are any unfavourable hidden pasts.
Finally, we carry out a HPI check which includes an outstanding finance check amongst the usual HPI reporting criteria.


Comprehensive Vehicle Inspection:
A lot of our customers also wish to know more about the condition of their BMW Z4M and therefore take advantage of the opportunity to have their Z4M with a dedicated M-power specialist like Redish Motorsport.

This consists of us (arguably one of the UK's leading BMW E85 E86 Z4M specialists) studying the mechanical and underside components of your BMW Z4M to report on the condition of them.

We are extremely thorough and will even report on missing undertray screws, and incorrectly used or sited fixings for example.
We are all M-Power owner/drivers at Redish Motorsport and currently (2020) have 9x M-Power vehicles on the road between us staff and have even built many M-power vehicles from bare bodyshells.

So we're perfectly placed to inspect, check, test, and report on all manor of items like:

  • Engine & Ancillaries
  • Fuel System
  • Cooling System
  • Exhaust System
  • Clutch System
  • Gearbox & Gearshift 
  • Propshaft & Driveshaft
  • Front Axle & Suspension
  • Steering System
  • Rear Axle & Suspension
  • Braking System
  • Wheels & Tyres
  • Bodywork including corrosion assessment
  • Vehicle Exterior & Interior Trim
  • Vehicle Electrical Systems
  • Lighting & Instruments
  • Audio & Navigation
  • Parking Sensors
  • Airbag & Safety Systems

Once we've carried out our 'Comprehensive Vehicle Inspection', we will write a detailed report of any findings and present that to you in the form of a printed 'Advisory Report'.

We will also video every point which we have noted in our printed report, and provide you with a personalised video link to watch in your own time, at your own leisure, as many times as you wish.
Our personalised video's are often 15-20 minutes long but can sometimes extend to 30-40 minutes.


Paint & Bodywork Inspections:
We will inspect the general condition of the paintwork using our keen eye for detail and moderate understanding of detailing procedures and years worth of bodyshop painting experience.

We will report on which body panels have poor paint in quality/finish/colour match.
We will report on any potential panel gap or alignment issues.
We will check for any signs of accident damage or panel replacement and advise.


Conrod Bearings:
There is no sure way of telling if the Conrod Bearings are beginning to wear.
Apart from changing them, the only option people have is to carry out an Oil Sample.
We will take a sample of your engine oil and send it away to Millers Oils Ltd for analysis.
Upon receipt of the pdf report a week later, we will forward this on to you which will help you understand if there are any abnormal wear metals present.

Vanos:
We will carry out a Vanos Test (using BMW DIS/ISTA Diagnostics) to check Relative Timing, Leak Deviation, and Solenoid Response Time.
We will also remove the Engine Rocker Cover and inspect the Exhaust Cam Hub as these like to snap one or both of the drive pegs.

Headgasket:
We will carry out a Compression Test and a Leak Down Test to check absolute compression in all 6 cylinders of the engine and also report on any potential pressure leakage.
This will help identify if there is a Headgasket, Valve, Piston Ring, or Engine Block/Bore issue.

Roof Drains: (E85 Convertible only):
We will remove the 2x lower Rubber Grommets, then use a long stiff rod to push up the drain tracts to see if there are any obviously blockages in the tracts.
Then from the top we'll pour water into the Roof Drain Pockets/Buckets and check the water can exit through the Roof Drains and onto the ground.


Price:
£350.
 (We will need your E85 E86 Z4M for most of the day 6-7 hours).
However, if you go on to have any one of these 'common jobs' carried out with us within 12 months, we will refund you £200 of this £350 PPI fee.


Final points to consider:
It goes without saying that our reputation and knowledge on this platform are second to none - just check our Google & Facebook reviews, and forum feedback.

We can say hand on heart that you will not find a more thorough or detailed set of reports and personalised videos anywhere in the UK. 
We're so confident with our customer service and work we provide that we invite you to put us to the test. 
You will not be disappointed!

One of the most important things to understand is that we are regularly able to save purchasers thousands of pounds when at the negotiating stage (during a pre-purchase inspection) due to the amount of detail we provide.

Many times over the years we've been able to save purchasers from buying a vehicle which presents well on the exterior but is riddled with corrosion underneath and full of leaks and original parts which are causing no end of problem and will end up a large financial challenge to start a recommissioning/maintenance plan going forward.

On the flip side we're had some vehicles sent to us from high end specialist dealerships which are presented so well that we struggle to find issues.
They are the pinnacle of their class and it only helps strengthen a sellers position when having Redish Motorsport back up their claims with printed reports and personalised videos.
In turn this add value to the vehicle and put the seller in a stronger position knowing they have such a fine example for sale.
At the same time this can also help seal a deal as the yet-to-be-found purchaser has total reassurance from the leading specialist in the field that they are not likely to find a better example.
