Jb mod is it or not?

BashShah · 01-11-2013, 12:31 PM

I bought a used E90 335i Sedan.

I am going to dealer for the first time tomorrow morning to see why I am getting g a hesitation or jerking while very light acceleration.
They will just be driving with me.
I am due for the Ecr-b0001-10-001
Campaign number recall.
They will be programming my ecu.
Emission related.

I have no engine check lights at all.
No errors what so ever.

I am aware of the hpfp and wastegate issues which I believe there is a recall.

So if there is a problem, and they can fix it, I want to make sure the vehicle is not modded with something like JB+ or something.

How do I tell..
Any advice will be appreciated.

Ps: called all local dealers, car has never been to them.

That is why I am curious....why not, not even once.

Originally car is from Cali.
Imported to Canada in 09 July.
Since then no records.

Regards,
DN

Not sure about your question, but you may want to post in the N54 section....

You're posting in the wrong section...

You just have to pop the hood and search in the engine bay... If it has a JB you will find it...

It gets difficult when the car is flashed and you don't have the possebility of driving a stock 335i...

Well the JB+ runs inline with the TMAP sensor, which is on the chargepipe by the diverter valves. You may have to remove the airbox to see it.

JB3/4 would be installed in the ECU box. With JB4, you can just go into the command mode (hold volume down and channel select down) and the instrument cluster will turn solid orange. Procede is also installed in the ECU box, but has slightly different controls for the command mode.

If you want to be absolutely certain, just look in the ECU box. Getting into the ECU box isn't difficult, there's just a lot of steps that make it seem overwhelming the first time. You could also see if anyone in your local section can give you a hand.
