Diagnostics help
- Thread starter JayDublin
- Start date
If it was me I would be going to some one who has dealt with them before. a needle in a haystack wouldn?t fill me with confidence maybe a few of the lads who have owned them might help out or fixed them before. did you get work done service etc that might of knocked off something boost hose or intake something simple it?s very hard to tell jay without giving a very detailed symptom list

Cheers Gary. Car drives fine and not making any strange sounds or rattles other than lack of mid range power. First turbo comes on fine but then there is a serious lag before second turbo comes on. It does eventually boost but comes on about 6000rpm. My mechanic said his diagnostic will show limited info due to the car and maybe that someone here might be able to help get diagnostics. Thanks again

You sure that's not just VOD?
Valley Of Death as they call it.
There's a transitional phase between primary and secondary turbo in the BE B4s, generally around 4.5k rpm if I'm not mistaken...
If that's what your talking about its perfectly normal, you can buy a zerosports sequential controller to set where secondary stage comes online and set it to your driving style. Pricey nuff tho, also, if you change up a gear while coming to the end of the primary stage it sometimes can like really exaggerate the VOD

Ah yeah I'm well aware of the dreaded VOD but this is not that. It's a far more significant delay of boost. Cheers though[emoji106]

Diagnostics.
To read codes, plug the two black ones together, switch ignition to on, count the flashes
The long pulses (1.3 Seconds) indicate Tens and the short pulses (0.2 Seconds) indicate ones. Pulses are separated by Short Pauses (0.2 Seconds), multiple codes are separated by a Long Pause (1.8 Seconds).
The simplest way to retrieve codes is to write the codes down in a sort of Morse Code (dots and dashes), and start a new line when you get a 1.8 Second pause (for NEW code), and then add the actual numbers up after code retrieval is completed.
--- CODE EXAMPLE, SINGLE CODE ---
1.3 second pulse (10)
0.2 second pause
1.3 second pulse (10?.for a total of 20)
0.2 second pause
0.2 second pulse (1?..for a total of 21)
0.2 second pause
0.2 second pulse (1?..for a total of 22)
0.2 second pause
0.2 second pulse (1?..for a total of 23)
(Code 23 ? MAF Sensor)
--- CODE EXAMPLE, MULTIPLE CODE ---
1.3 second pulse (10)
0.2 second pause
1.3 second pulse (10?.for a total of 20)
0.2 second pause
0.2 second pulse (1?..for a total of 21)
0.2 second pause
0.2 second pulse (1?..for a total of 22)
0.2 second pause
0.2 second pulse (1?..for a total of 23)
1.8 second pause (this means NEW code)
1.3 second pulse (10)
0.2 second pause
0.2 second pulse (1?..for a total of 11)
0.2 second pause
.2 second pulse (1?..for a total of 12)
(Codes 23 and 12, MAF Sensor and Starter Circuit)
How to clear them!
Ensure engine is at normal operating temperature, turn engine off
Locate the two ECU connectors, located under the steering column and consist of a black plastic male and female connector, and a green male female connector
With the ignition OFF connect black to black and green to green.
Turn on ignition, do not start the engine, depress the accelerator pedal to full throttle, then return it to the half-throttle position and hold for a few seconds, and then release
Engine Check lamp turns on
Start engine and then drive for at least one minute, keeping road speed above 10mph.
ECU is now re-set.
At this point the check engine light should start to flash the all clear signal (steady 1/2 second interval flashes). If the check engine light does not flash, or indicates some other sequence, there is a fault present in the system, and should be professionally checked for necessary repairs.
Stop the car and turn off the engine.
Disconnect the black and green connectors.

The chance of actuator arm sticking is slim to none
Turbos again unlikely if no unstrange noises etc. But worth a camera inspection etc
Most likely a sensor issue pulling ecu back
