Bmw E46 3 1998-2005 Rear Wheel Arch Repair Panel / Right Rh. Wings & Quarter Panels » Product details. £99.99 plus shipping. BMW E46 M3 Rear Wheel Arches Rusting. The 2nd most common E46 enquiry we receive (after RACP work) is 'Rear Arch Rust'. All E46 Rear Arch corrosion starts from the Inner Arch area. Regardless if you can only see a small blister on the Outside Arch area. We can guarantee you that the epicentre is hidden under Seam Sealer on the Inner Arch area.
Despite being almost a decade old now, the E46 is still one of the better looking BMWs of all time. It has muscular wheel arches, the right stance and a great profile. It’s simple yet exciting.
What is the purpose of fender vents?
The main purpose of fender vents is to relieve built-up air pressure from inside the wheel arches which causes aerodynamic lift. Typically, there are air intakes in the front of the bumper directing air over the brakes to cool them. This air gets trapped in the wheel arches and creates high pressure. High pressure results in lift over the front wheels reducing traction. Relieving this built up high-pressure system in the wheel arches reduces front axle lift thus increasing safety and grip.
In addition to high pressure,tTrapped air in the wheel arches also creates aerodynamic drag. Drag is the force of air pushing in the opposite direction of the vehicle, reducing efficiency. Some research suggests wheel arches account for up to 30% of aerodynamic drag of a vehicle. With fuel efficiency ratings becoming increasingly more strict on modern vehicles, you can understand why so much attention is being directed towards the reduction of this inefficiency. Efficiently routing air into and out of the wheel arches increases fuel economy through the reduction of drag.
Another benefit of fender vents is to efficiently vent hot air generated by heavy breaking out in the air stream. Quickly relieving hot air generated from the brakes makes room for more cool air to pass over the brakes, thus increasing efficiency. Finally, it is worth mentioning that trapped air in the wheel arches also contributes to cabin noise. Reduction of cabin noise is more pleasant to drivers on long trips reduces driver fatigue.
* For another topic on aerodynamic efficiency and lift reduction, read our article on rear diffusers. It explains what they are used for and how they work, click the link HERE.
Do the fender vents vent hot air from the engine?
No, not on BMWs. Some vehicles tie in the fender vents exhausting hot air trapped under the hood and out the fender but on BMW models the fender vents are not related to venting hot air from under the hood.
Are all BMW fender vents functional?
No. Some are just for show. The E46 M3, for example, has nonfunctional fender vents. The original design was intended to use functional fender vents however the engineering team decided the vents were not needed through testing. The final vehicle design was already approved by the marketing team however and as a result, the fender vents stayed with the design of the vehicle but were made nonfunctional. Since the E46 M3, each subsequent generation M3 has had the fender vents become an iconic design element of the car. The M4, however, does have functional fender vents.
What does BMW call their solution to efficient air flow?
BMW is marketing these new aerodynamic features as “Efficient Dynamics”. 'BMW EfficientDynamics is the name of the strategy from BMW to minimize fuel consumption and CO2 emissions while, at the same time, increasing dynamics and driving pleasure. It is a package of functions covering the drive system, energy management, and vehicle concept – and is a standard feature in every BMW.' - BMW.com

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 M3 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 M3 chassis number.
This is a 3 page document which details everything which has to be done/replaced/checked on the M3 Inspection 2 Service.

Valve Clearances:
We like to strongly promote that the M3 S54 Valve Clearances are checked and adjusted at every Redish Motorsport Inspection Service.
Even today in 2020 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 M3'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 M3 with us whilst parts are ordered into stock (like the main dealers usually do).
We are true M3 specialists and therefore cater for every eventuality.
After all, we've carried out over 150x S54 Inspection 2 Services in the past 10 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 each from BMW and there's a maximum of 24 in your M3'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.

Timescale:
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 M3 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.
