Throttle Valve Actuator source

Most of the TA rebuilders will replace the gears and mosfets which will set you back around 200 bucks total for both if you do it yourself.

100v, 20a, style 252 mosfet.

Would replace out all 4 mosfets (the 2 sets next to each other.

The gears can be bought cheap on eBay, but the OEM shaft need to be reused and the gear needs to be drilled and pinned to the old shaft. The i6 ones mentioned above have the shaft included which makes for an easier job.

Changing the gears and mosfets alone will not always work, they need a a full electrical upgrade. voltage regulators, memory chips, CAN IC's.

Plus 80% of the 3rd party gear kits on the market are worst then the worn BMW ones.

Please believe me, I know these inside out, enough people have recommended my rebuild service on this thread alone.

I now stock these on the USA for a next day delivery

Mate, you do understand that by changing or so called "upgrading" each of these components you're literally changing the whole design spec of the module? Collectively, they MIGHT even cause some unforeseen situation.

From your other post..

Components on the actuator itself are already automotive grade, which is -55°C ~ 175°C (TJ), doubt you could do better than that.

Feel free to correct me if I'm wrong

Craig what sorts of issues were you experiencing?

I floored my car today and it literally did nothing (like it stalled or something) then all hell broke loose and it took off. Difficult to describe except it was like a total loss of power momentarily.

Is this indicative of TBA failing?

I havent received any error codes.

PS - No it wasn't traction control, it did the same thing whilst in neutral (completely stopped)

Throttle Actuators fail anywhere from 30k miles up to 70k miles. Some even last slightly longer than that. But every single one of them will "fail" at one point or the other. Even if you buy a new OEM unit, it will fail.

That's why most people are going with the Rebuilt units that have upgraded gears and upgraded internal components backed with a transferable-lifetime warranty. So you never have to worry about them again. And the greatest thing is that they are affordable. Anywhere from $300.00-$800.00 in savings a set, depending on what country you live in.

It's always a better idea to replace both at the same time. It's a hassle doing all the work again to replace one. Especially if you're taking the car to a shop, you will be charged labor twice. So why not just replace both at the same time.

Majority of the time, you will only get an error for one unit first. The error for the other unit follows in the upcoming weeks or months, if you're lucky.

thanks a bunch

Hi Abdul

I order and paid for a TA on Oct 16 with express shipping. I've emailed your business 3 times during that time with no replies. The tracking provided is not valid according to USPS.

Can you please reply to your emails?

thanks,

Phil

That's very strange. I didn't get any email. Let me check and see if they are going to spam it even the promo section. I'll shoot you an email in a few minutes.

The tracking number is automatically uploaded to your order. I'll send it over again. I'm sure you have it though.

Can't you get bmw replacements from fcp euro that offer a lifetime warranty.

[phillay]

you could get oem but if they fail again soon, it's a bit of a ball breaker to get them out. I've done this twice in the last month. I can get them in and out within 45 mins at home in the driveway.

Thanks mate, all good now.
