Alpina B3 Bi-Turbo E90 Saloon Maintanence - No. 104

Post by B3FNA » Mon May 13, 2019 6:52 pm

Afternoon all, just thought I'd share some maintain I've had carried out on my Alpina B3 (E90) Bi-Turbo which has covered 104,000.

Things I've done/doing so far:

1. Performed a full gearbox fluid, filter, seal, and pan flush/change including the mechantronic sleeve. It drives and shifts a lot smoother with no jerking in gear changes and just silky smooth changes very pleased with this. (Dealer parts).

The original pan on a lot of these cars are made of plastic so can't be reused and the filters built into the pan so have to replace the entire pan assembly with filter built in not cheap! You can probably source the correct ZF pan cheaper elsewhere but I didn't want to risk fitment etc for something this Important. I bought 9L of transmission fluid from the dealer and have 2L left over.


2. Changed rear differential seals and replaced fluid with brand new fluid. (Dealer parts).

If you plan on doing these they are different for an Alpina, the standard 3 series seals didn't fit to small. Alpina fit bigger seals from a different BMW (X5, 7 series etc). I'm assuming because it's not a standard 3 series differential that's fitted to the car.

See the image below. On real OEM it will come up part number: 33107505604 for your Alpina and the dealer will supply you the same this is incorrect.
You want part number 33107505605. The difference is shown below in the pictures with the 604 seal and compared to the seal from my car on the right hand side which is 605. Image


3. Replaced the wiper blades!!

4. Performed an oil service on the caramd had recall work carried out. (BMW Dealer).

5. Changed rear shock absorbers and rubber mountings. (Sachs). My advice to B3 owners is that these do not need to purchased from a dealer as they will sell you sachs shocks in a bmw box for triple the price for what you can source yourself I got mine from a well known European parts suppliers not sure if I'm allowed to mention names but I made sure they're M-Sport shocks.

I emailed Alpina to confirm that they do not change the standard BMW shocks on a B3 Alpina (E90), which they confirmed to me and happy to share a screenshot should anyone want to see this. I assume this is due to the car being based on a 335i which by default come with M-Sport suspension even on an SE model and therefore do not need to be uprated. The ride is comfortable on this suspension I must say.

6. Replacing all of the rear rubber bushes upper/lower control arms this week. (There is currently one worn out bushupper control arm) so don't want to revisit this again for a long time decided to replace the lot! Was tempted to get the front done but will leave it for now as there's no wear or play there! Have sourced Lemforder bushes for the purposes of replacement which are what the BMW bushes originally from anyway I believe.
7. 2 Brand new Continental Sport Contact 6 tires for the rear. I know that Alpina only recommends Michelin as that's all they test but I've had Pirelli and Contonental tyres on many previous cars including my previous 7 series and they performed exceptionally well so happy to make the switch here also!!!


Future planned preventative maintenance work:

Walnut blast from a BMW specialist to remove any carbon deposits.
Water pump replacement don't think it's been done.
Replace auxilary drive belts (let me know your thoughts here?)
Front shock absorbers.
Front suspension arms/bushes.



Changes Planned:

Alpina side pin stripes in gold.

M3 Cowel Mod (potentially). If I can find the original M3 parts to do this. It just makes working on the car removing engine cover a lot easier as currenttly you have to remove the pollen filter etc.


Would love to hear your thoughts.
