E85 E86 Z4M Inspection 2 Service

The Redish Motorsport E8x Z4M Inspection 2 Service (which is widely recognised as the most comprehensive on offer in the UK): £985.

Having worked and trained at a BMW Main Dealer (Wellsway, Bath) for the 6 years of 2001-2006 (spanning over the entire M3 S54 production/delivery) James Redish set his standards extremely high when building Redish Motorsport and especially his trademark Inspection 2 Services.

This means as a company Redish Motorsport strictly follow and always adhere to BMW service schedules and repair instructions whilst using BMW Special Tools and predominantly Genuine BMW Parts.

First of all the vehicle receives it's protective internal coverings:
Genuine BMW Seat Cover
Genuine BMW Gearknob Cover
Genuine BMW Handbrake Cover
Premium Steering Wheel Cover
Premium Double-Size Floor Mat Cover:

Pre service checks:
Once in the workshop we use BMW Diagnostic Software to check the live-data of the engine's temperature to see if it's below BMW's specified value of 35'c to be able to carry out the Valve Clearance Process (more on this below).

We will also check your service book and service counter (on the cluster) to see if the Z4M is due the separate service BMW call the 'Annual Service' which entails either the Brake Fluid Change (every 2 years) or Coolant/Antifreeze Change (every 3 years), or both.

Initial paperwork:
We then print out a date stamped 'Inspection 2 Service Check Sheet' from a BMW system using your unique Z4M chassis number.
This is a 3 page document which details everything which has to be done/replaced/checked on the Z4M Inspection 2 Service.
We follow this meticulously and once all items have been completed and ticked, this paperwork is handed to you to keep for your Z4M service records.

Main Worklist:
The following items are carried out during our Redish Motorsport E8x Z4M Insp 2:
  • Castrol Edge Supercar 10w60 M-Power Engine Oil
  • Genuine BMW Oil Filter Kit
  • Genuine BMW Spark Plugs (DCPR8EKP)
  • OE Pollen Filter
  • OE BMW Air Filter
  • Valve Clearance Process (Any shims required charged additionally).
  • Castrol Transmax 75w90 Gearbox Oil (MTF-LT3)
  • Castrol Transmax 75w140 LS Diff Oil (SAF-XJ)
  • Redline FM Booster LS Diff Additive
  • Genuine BMW Diff Filler & Drain Bolts
  • Vehicle Check with Advisory Report
  • Digital Picture Pack of key points of the service
  • Service Book stamped
  • Service Mileage reset

Valve Clearances:
We like to strongly promote that the Z4M S54 Valve Clearances are checked and adjusted at every Redish Motorsport Inspection Service.
Even today in 2024 we read and hear all sorts of horror stories regarding other specialists and even main dealers just 'listening' to the engine to decide if they need adjusting, or carrying out the process but offering no paperwork, no invoice for shims, and no pictures, or even worse trying to talk the owner out of the valve clearance aspect (laziness) and offering to reduce the service costs accordingly!

On the contrary Redish Motorsport go so far to proving we carry out this crucial practice that we always take a digital picture of your engine 'open' with our BMW Special Tools laid out, and your Reg No. visible.
This not only gives you peace of mind the process 
has been carried out, but adds great value to the Z4M's important history records.

We have over 120x brand new Genuine BMW S54 Valve Shims in stock at Redish Motorsport all organised and presented in the Genuine BMW Blue Special Storage Metal Case.
Should we find any of your 24 valve shims which are out of BMW's specified tolerance of Inlet 0.18mm - 0.23mm and Exhaust 0.28mm - 0.33mm then we will replace them during the process.
This makes it very convenient as you don't have to come back to us for a separate visit, nor leave your Z4M with us whilst parts are ordered into stock (like the main dealers usually do).
We are true Z4M specialists and therefore cater for the majority of eventualities. 
After all, we've carried out over 220x S54 Inspection 2 Services in the past 14 years - so it's safe to say we've honed our procedure to be as smooth, comprehensive, and professional as possible.

We don't charge you any additional labour for changing valve shims. 
We only charge for any new valve shims IF you need them.
These are priced at just £3 plus VAT each from BMW and there's a maximum of 24 in your Z4M's S54 engine - which means at the worst case scenario an additional £72 in shims (if you require all 24 replacing) but that's extremely rare.

An extra 'Vanos' check that we do free of charge:
During the Redish Motorsport Z4M Inspection 2 Service, we also carry out a very important check which isn't on the BMW Inspection 2 Service Sheet.
We check (and if necessary advise on):
  • Exhaust Camshaft Hub (Vanos Drive Pegs can be found snapped)
  • Exhaust Upper Plastic Timing Chain Guide Rail (often found worn)

You also receive 12 pictures of key stages of the service which are listed below:

Picture of the new service parts to be used
Picture of the old engine oil draining out
Picture of the oil gearbox oil draining out

This work can be carried out in 1 day, BUT we do need to carry out the Valve Clearance process when the engine is at or below 35'c (as shown in the BMW Technical Instructions).
So this can either be achieved by dropping your Z4M off to us the day before the work is due to commence, or by arriving early on the day of work around 7-8am. 
This allows the engine to cool naturally during the morning and usually by lunch (in winter months) or early afternoon (in summer months) the engine is below 35'c (checked using BMW live data diagnostics) so that Valve Clearances can be completed accurately.

Optional upgrades/extras available:
During this service work, we offer the following extra items for the discounted rates listed
  • Engine Compression Test Report £65.
  • Vanos Test Report £65.

Annual Service:
As mentioned above, if you do require BMW's so-called 'Annual Service' then these are separate service items which are listed in a separate part of your Service Book, with a separate Service Light on the dash (clock symbol), and therefore are charged separately too.
You may not need these, but if you do then our prices are listed below:
  • Brake Fluid Service and full system bleed using ATE Typ 200 Brake Fluid £89.
  • Coolant Service and system bleed using Genuine BMW Antifreeze £95.

You will receive an extensive amount of paperwork for this Inspection 2 Service.
We provide you with the following printed paperwork to take away and including in your Z4M's History Folder:
  • BMW E8x Z4M Inspection 2 Service Check Sheet (unique to your chassis no.)
  • Valve Clearance Report with all measured (and any replaced) clearances
  • Advisory Report (things to consider for the future)
  • Invoice (detailed will all works carried out and on headed colour paper)
