Help - V3 install - cable to relay confusion

Tobias1980 · 07-14-2008, 07:50 PM

After advice from Kyle I tried this in the following order:

ECU Reset
Firmware upload (V3 official)
Map update, Stage 0 non doomsday
Valet 3500 RPM

Result: Car runs perfect stock.

I took walet back to 300 RPM and then I was back to max 10 PSI and LIMP after a few accelerations.

If you are only seeing 10psi on Map2, that's the reason why you are throwing a code. The code will be for 'boost target not achieved'. The question now is why this is the case. The most common reason is that there is a boost leak somewhere in the system. Is your car otherwise stock? Any mods at all?

What does the boost look like in the PROcede reader software? Do you have a multimeter available?

Hi Shiv and Scalbert,

I think I have a boost leak. Yesterday the car started to give a hissing sound and today it is a constant swoosh sound at boost application. OBD code is 0237 "boost sensor A error" (translation from swedish).

I recently hit a deer with the car... BMW will loka at my car tomrrow morning.

I attach a log file of a WOT run when I had a LIMP.

What do you guys think?

scalbert · 07-15-2008, 09:29 AM

And it runs fine with the bypass plugs in; even normal looking boost levels?

Do you have a multimeter where you can do a continuity check? I suspect there may be a boost leak but would like to confirm one thing first.

Hi, we have found damage on the aluminium intercooler pipe. Looking down on the pipe on the passanger side of the car at the bend downwards it has been smashed a bit (negative bump), it is also a bit dirty on that spot.

get that pipe replaced asap, dont boost anymore until its fixed. Your stressing your turbo's more than necessary everytime you call for your engine to boost....

The first two pictures are my pipe, the last one is my friends:

It may very well be leaking but at a minimum, that is a major restriction which could induce the same symptoms.

Tobias1980 · 07-16-2008, 02:49 AM

Hi,

I was at BMW this morning. The connection between the aluminium pipe above and my intercooler was loose. BMW has ordered a new pipe.

The strange thing is that we tried my V3 on another car. It was also runnig very bad, huge hiccups during acceleration and LIMP at WOT just like my car.

There may still be something with the connections to the relay. That was the reason for the query on access to a digital multimeter.
