My RDC control unit for the Tire Pressure Monitor (TPM) system has been ruled faulty by the dealer. I want to be able to recode the replacement unit. From what I can tell only GT1 can do this. I'm planning on keeping the car for a while and figure GT1 (on ebay) will pay for itself in dealer visits, considering the last diagnostic check was over $100 and left with out anything being fixed.

Here is the setup:

For most owners who are maintaining one or two street cars, the need for bi-directional communication and programming is relatively low. This is also typically true for the need to access diagnostic modules outside of basic ECU/engine trouble codes or airbag issues. I'm not saying it doesn't happen, but the chance that instances of these needs adding up to cover the cost of proper equipment to handle these tasks is fairly slim.

Unsupported (unlicensed) equipment and diagnostic modules are abundant online. I've heard of good results, and I've heard of problems ranging from communication issues to completely useless products. I'm not familiar with the seller linked, nor can I say anything good or bad about any particular source for 'knock off' products. Authentic, licensed GT1 units cost 10x the listed price on that auction.

The majority of BMW owners willing to diagnose and work on their own car prefer a simple, hand-held, plug-and-play tool like the Peake scanners. They read BMW Specific codes, not OBDII (or "extended OBDII" so-called manufacturer specific codes). They read directly from the factory diagnostic module and provide the same code results the dealer sees. For $139.95, one saved trip to the dealer for a check engine light diagnosis nearly pays for the tool - let alone the theoretical cost of your time and convenience.

The tools, however, will not allow bi-directional programming, nor access to ancillary modules (ABS/DSC/Transmission, etc...). However, these represent a fraction of real-world needs the typical Do It Yourselfer will encounter.

Couple this with Peake's twenty year track record as a trusted and dedicated BMW-only manufacturer, it's difficult to see why the TYPICAL BMW owner would choose any other product.

As noted above, ken@bimmertools if you have any questions about these products.

Good luck!

Ken

Yeah, the practical side of me is saying just get a basic scanner, but then again, by owning a BMW my friends would argue I'm not very practical in the first place. So why start now......LOL

Yeah, you're right, for most maintenance issues the scanner would be sufficient. But a working GT1 means, for the most part, dealership freedom......FREEDOM! I'm so tired of dealers ripping me off. I'm an Electrical Engineer, not having complete access to my car's electrical system is driving me crazy.

Even for engineers, I recommend reduced risk and buy it from anywhere but ebay, and only with a creditcard where a charge back is possible. If it doesn't work, then the money is completely thrown away, and ebay will run you in circles until you go away.

Having a system like that may keep you dealership-free with regard to diagnostics/programming - but do you have the ability to repair EVERYTHING the extended diagnostic capabilities would reveal? With the rarity of needing this level of electronic communication for one car, it is far more likely that mechanical issues will outweigh any diagnostic savings with that setup.

For me, I'd avoid a large investment in a questionable product that will (most likely) ultimately wind up performing the same duties as a simple scan tool. However, expanding my capabilities to perform other repairs and maintenance will save me more trips to a mechanic than electronic connectivity. Hard tools, jacks, stands, specialty equipment, etc..., are all things that would provide mechanical independence.

Have a look through the pages on this forum. You'll find a mountain of questions, concerns, advice, and articles relating to mechanical issues that don't involve the need for sophisticated diagnostic tools. Suspension, bushings, driveline components, brakes - all things that are wear items that you'll certainly face as a long term owner.

Granted, I'm making the assumption that you don't already have a garage full of tools and manuals to get these jobs done. If that's the case, an advanced computer would be a cool add on. If not, though - see above!

Yeah, seems to be the recurring theme with these cheap GT1 kits on Ebay.

Being completely mechanically independent is one expensive proposition. What I need is a good mom and pop shop alternative for doing those things out of reach for DIY.

Anybody know of a good BMW shop in Central Pennsylvania?

What is the best place for renting BMW specialty tools?

Yes, please let me know! The Tire Pressure System - RDC has been and will continue to be a maintenance issue for me. Especially if these wheel electronics modules only have a battery life of 5 years. Would be interested in any tool capable of re-coding this system.

Still, has anybody personally had success with the GT1 units being sold on ebay from China?

other problem is GT1 is dead and no longer used by dealers after march. BMW build new modules that only accept coding from current tools so GT1 will no longer code older control modules after a certain point

Your best bet is to buy a pass through tool for about 800 and then log onto BMWtis.com everything you need to do something you have a full GT! with all options. Its $30 for 24 hour access

Cool, First I've heard of this. What is the pass through tool and where do I get it?

Is this the future if diagnostic software? Are BMW dealers changing to this system as well? Seems to me it's a lot easier to maintain one up to date database this way.

Also, which pass thru kit went for 800?

For the ones listed on bmwtis.com prices online seemed to be about

I+ME Actia - PassThru+ XS $1096 US
Snap-On - Pass Thru Pro $1595 US
ProgRama Inc.- PC Retriever $1072
