JB 4 remove and limp mode

[mkot9]

But that could be a problem with the car and how do they prove it, is what im worried about?

 

[Twinz]

If shadow codes are cleared before it goes in then there is nothing to see.

 

[Twinz]

Does BMW not see on the telemetry that the car has been boosting higher than stock?

Only a stock boost value will be shown.

 

[mkot9]

Perfect, thanks for all the help guys and I will post as soon as the plroblem is sorted, thanks again!

 

[Twinz]

Contact Kish or myself if you really worried or stranded....i am sure we can do some remote troubleshooting. :thumbs:

 

[mkot9]

Perfect, thank you so much Twinz

its possible that you didn't zero the map before removing the jb

 

[mkot9]

What do you mean with zeroing it?

 

[Javbrat-wp]

sorry by that i meant switch it to map 0 then remove the jb, this happened to me twice when i had jb.

 

[mkot9]

I have literally tried everything now, (for 2 days) and I cant fix the problem, to whom can I take the car and pay for them to sort out this nightmare? Because I'm out of ideas and tired

chat to your installer... normally they offer back up support...

Did to try reading for codes with the JB on? I know you stated that when it's removed the light comes on but you probably have "Auto Delete" on? Switch it off and check the code.

So tonight I contacted Burgy and we tried everything, the car is still going into limp mode, Im a bit stressed out to what BMW may say, and if they would void my warranty???

Terry's answer

Typically it means the DME TMAP ground has been damaged. You would
need to bypass it by connecting it to chassis ground. The JB4 includes
a similar bypass.

How do I do this?

 

[Dean ///M]

Join a piece of wire to the black wire on the TMap connector and run it to ground (anywhere on the chassis). I did mention TMap earlier. Probably the wire is broken on the connector itself. The TMap is the multicolored plug with 4 wires black, red, yellow and green.

Check the TMap connector & pins. Or else disconnect battery for 30mins.

But u never said thanks, Lol just joking. Pic below

Perfect thank you so much Dean. How would I explain this to BMW if it doesnt work, or is a wire tap reversible?
