Hi guys,

We often get asked for small maintenance, service and repair items. Our business model is not really set up for this - handling small items is fiddly and time consuming.
Also some repair options for more expensive items

We thought it might be useful to set up a money saving tips thread - where owners can be pointed to where they can buy common items and not pay the dealer price.
The more you save on the boring stuff - the more you can spend on the fun stuff with us!

We are only posting where the identical parts to OEM can be bought for less by not buying from Audi.
We are not suggesting any OEM replacements or alternatives


We will slowly add to this.

1. Gen 1 A/C compressor
Dealer price is $1,569.23
You can buy the identical compressor from Denso for less than $450
Denso ref 471-1505

2. Gen 1 V8 and V10 Ignition Coils (pre-facelift excluding GT)
Dealer is $63.33 each
Buy the same part from Bosch ref 0221604800
Will cost you around $30 each

3. MAF sensors
Dealer is $330 each
Buy the same part from Hitachi ref MAF0057
Will cost you around $120 each

4. Gen 1 V8 xenon headlight bulb
Stealership wants $193 for this
You can buy from Phlips ref 85415C1
Less than $50

5. Faulty ECUs
Stealership wants around $4,000 plus an install fee
Use a repair service - probably less than $1,500 for the two with a lifetime guarantee
Repair services can send you them back and you just plug them back in - no dealership involved

6. Faulty R-Tronic hydraulics
A new unit will cost you around $4,000
A professional overhaul around $2,000 - and they will use upgraded components which will give better long term reliability and improved shifting

7. Scruffy looking black exhaust tips
Go to your local wheel repair shop and get them powder coated for less than $100

8. Mag ride delete modules
Cost from KW is $450
Make your own set of 4 for less than $80
Will post components soon

For a plug in mag ride delete solution

Buy 4 of these plug in tails

And 4 of these resistors
=[/URL]
OSMAN ,
U ROCK
Solder one resistor onto each set of tails.

The secure them using some tie-wraps to strap them onto the car
This pack will last you a lifetime for all sorts of uses

9. V8 Fuel Injectors - pre-facelift
Stealership $246.67 each
Buy from Hitachi ref FIJ0008 for around $90 each

10. Gen 1 Wiper Blades - LHD (not for UK, Australia, NZ etc)
Stealership $121.67
Buy from Bosch for around $50 - ref 3397014119

V10 Fuel Injectors (2009-2010)
Audi 079-906-036-AA $261.57 each
OE Supplier Hitachi part number FIJ0038 for around $90 each

Audi parts note: From 8/23/10. R8 5.2L instead use 079-906-036-AD (2011-2015). Also applies to 4.2L V8 (2011-2015.)
Note: This 2011-2015 part number does not appear to cross to Hitachi, but instead to Continental.

I may have just been unlucky, or my circumstances unique, but going down this route caused @Ricky.REP no end of problems and we ended up reverting to OEM injectors.
As such, I would advise caution if considering using the Hitachi FIJ0008.

@TechNick What year is your car?

If you see the parts note I posted above, Hitachi injectors were used only from 2007-2010 V8 and V10 engines, and then replaced by (I believe) Continental injectors. The base part number 079-906-036 remains the same for all variants, but the suffixes are different, and there are multiple supersessions.
  • The 2009-2010 V10 Hitachi FIJ0038 (to 8/23/10 build date) Audi Part Numbers are: 079-906-036-AA, 079-906-036-C
  • The 2007-2010 V8 Hitachi FIJ0008 (to 8/23/10 build date) Audi Part Numbers are: 079-906-036-AB, 079-906-036-D
  • The 2011-2015 V8 & V10 Continental (from 8/23/10 build date) Audi Part Numbers are: 079-906-036-AD, 079-906-036-AC, 079-906-036-T, 079-906-036-N, 079-906-036-G (no known Continental OE cross-reference part number; apparently these are only sold through Audi)
Given all of that variation, it's unclear to me which injectors from which suppliers are interchangeable across which different model years. It's definitely easier and safer just to buy the Audi part number version for the specific VIN, unless someone has some deeper insight to the differences and compatibility. It's even more confusing that injector part numbers are different for the V8 and V10 on 2007-2010 engines, but the same for 2011-2015.

Having a 2012, it was extra interesting because I have a prefacelift but it calls for the post facelift injectors. The “D” version is what ended up buying.

As far as I can tell, the injector change has nothing to do with pre/post facelift, but rather the 8/23/10 date that roughly corresponds with 2011 Model Year vehicles.

I’m assuming you purchased the -AD version? The -D version is for 2008-2010 V8 engines.

Given the confusion and unclear compatibility with injectors, I think the best way to avoid the R8 Tax is to have the injectors you already own tested and cleaned, and replace only confirmed failed injectors.

CleaningInjector.com appears to be the best option for GDI injectors. I called and talked to Keith, and he answered all my questions. Here are their process steps for servicing GDI injectors:

https://cleaninginjector.com
  • Injectors are externally cleaned, visually inspected
  • Injectors are tested for resistance, inductance, shorts, and current draw
  • Leak, spray pattern, and flow rate tests are performed and recorded
  • A three step ultrasonic cleaning process in three separate ultrasonic tanks
  • A high pressure back-flush is performed to remove any remaining particles
  • Leak, spray pattern, and flow rate tests are re-performed and recorded
  • New filter baskets, o-rings, and pintle caps are installed if applicable
  • The injectors are placed in sealed plastic bags
  • A comprehensive test report is prepared and returned with the injectors
  • Your injectors are shipped back to you ready to be installed in your vehicle

V8 and V10 injectors are physically different.

Then V10 hitachi BUJ and V10 continental CMPA onwards are physically different too.

They won’t fit in the head for start, the wiring is different and so are the drivers in the ecu.

Cheers Ricky

This thread is awesome!

Does anyone know if there are equivalent fuel sending units for the Gen 1 R8 V10 that cost less than the OEM??? TIA!

@R8-Stuff You should probably update the first post to include the correct model year details for the fuel injector cross-references (and add V10 engine details if you want.) Audi switched from Hitachi to Continental starting with Model Year 2011 (not with the 2013 facelift.) All the part numbers and years are listed in what I posted above.

But perhaps a better money saving suggestion is to have the existing injectors tested, cleaned, and verified by CleaningInjector.com instead of replacing them before having a failure verified.

I did the DIY mag ride delete and saved $300, thanks Osman! Also, I’ve purchased two really critical parts from R8-stuff and couldn’t be happier. An OEM clutch and entire suspension for my car. Communication was spot on throughout the process and prices were very competitive. All and all a great experience!
