Default ** AUTHENTIC ** Bosch 4bar sensors finally in stock! - 06-15-2018, 04:51 PM

Hey guys,

As most know we released a 4bar adapter and sensor kit a couple years ago. And while it worked really well for some, others found the sensors went out on them after a few weeks or months.

It took a few months to get to the bottom of it but it turns out that the majority of Bosch 281002576 4bar sensors out there are counterfeit and not as reliable.

Fortunately we were able to track down known authentic sensors at a decent price (in volume) and are again able to offer 4bar sensor kits.

The fakes look really good, it's hard to tell the difference. But I put together a couple of photos to help you spot it. The best clue is that if you paid less than $100 for the sensor itself it's probably not authentic.

You can order the sensor kits from us here: http://www.burgertuning.com/JB4_upgrades.html

If you bought one of the kits from us and want to upgrade to one of these higher quality authentic sensors no problem, we can upgrade the 4bar sensor for $50 + shipping for you (half off). Just email us with your orignal BMS order number and we'll help get you sorted.

Hey Terry,

I've been dealing with 2ABD codes on and off for a long time now. Changing values to account for elevation never did anything to help.

I purchased my 4 bar sensor on 5/22/16 for $99. Am I likely in the counterfeit sensor crowd?

Yes all the kits we sold were suspect as are any sensors bought on eBay, Amazon, etc, or anything that was less than $100 itself for the sensor. The suggested retail price on the sensor itself is in the $150 range.

Were these advertised as "bosch sensors" on your website at the time of sale, or just generic 4bar tmaps?

4bar 281002576 sensors. Which is what the box and sensor says. I'm willing to bet 90% of the people running 4bar sensors are running fakes which is why we hear about so many problems with them across all platforms.

If you got one of the old 4 bar sensors from us and are unhappy with it you're welcome to return it. Just ship it back to the address on our site along with a copy of your receipt from us.

The purpose of this thread is to inform people that we've learned most sensors out there are fakes and we've found a good supplier for authentic sensors.

That was my issue as well. I don't need the 4bar -- just bought it because it was cheaper than an oem sensor. I always chalked up the 2abd to user error, but ive tried everything over the years from voltage adjustments to changing boost solenoids. Turns out it was likely the sensor.

There are lots of different issues that can cause fault codes, most of them software related. 2ABD normally is a BEF scaling issue. We're running these sensors in our development cars but those cars never had an issue with previous 4bar sensors, so likely bad candidates for evaluation.

Good news Terry. Finally good to see the 4 bar option return.

Nice job providing the comparison between authentic and fake 4 bar sensor features - that's critical for anyone who currently has a 4 bar.

2ABC could be a failed sensor code, or setting on the JB4 or BEF.

For the 3.5bar TMAP = 1 is the setting and the default back end flash maps should work fine with it.

Yes, 3100 just means you have low boot mode from some code like 2ABC.

That app value is rescaled to the stock sensor regardless of what actual sensor is installed. So if you want to do diagnostics you could measure the actual voltage on your sensor. In the DME box it's the yellow JB4 wire on the male side of the connector.

Hi Terry

I am not very "electrical" inclined, do you have any tests you can recommend to see if my 3.5bar sensor has failed?

Rare a 3.5bar fails unless you got it off Amazon or eBay (those are all fake sensors). But you could check it's voltage ign on, engine off. At sea level should be around 1.2v.
