When it comes to diagnosis a cool head must be maintained when all around appears to be crumbling. Our relationship with the customer pays dividends during diagnosis where rapport is essential when things appear to go from bad to worse. It is very easy to jump to conclusions when the evidence gathered during diagnosis points to a particular component.

It is at this stage we should take stock and step away to ponder before we commit to our diagnosis. Why not ask yourself this same question before replacing the suspect component?

Asking yourself this question before committing to your diagnosis could potentially lead you to the actual cause and avoid embarrassment.

Volkswagen Common ECU Faults

The case study below is one such example where taking a step back at the correct point in time saved the day. The vehicle in question is a 1. A basic inspection including a road test confirmed no cutting out but a clear lack of performance under acceleration.

An emission and fuel quality test proved inconclusive and so attention was focused on the detection condition of the offending MAP Sensor fault code, P The detection conditions surround the power, ground and output signals of the MAP sensor in relation to engine speed, load and throttle position.

The integrity of power and ground proved stable with the engine running and so the functionality of the sensor had to be proven. A brief clean of the MAP Sensor and intake manifold port resulted in improved functionality of a component that could be attributed to the lack of power, negative fuel trim and cutting out. Whilst it may be tempting to measure the signal wire only based on the fact that if the signal is OK then power and ground must be OKtrue evaluation of any component must include power, ground and signal simultaneously, unfortunately consuming three channels of your scope.

The waveform below confirms a rapid response of the MAP sensor in relation to a WOT test, accompanied with the characteristic pulsations at idle speed that can be attributed to valve open and close events. A road test once again confirmed no cutting out but the lack of power remained.

As a result further diagnosis time was now required. It is at this point customer rapport comes into play as we have used up what is fondly referred to as the Golden Hour. Authorization via the customer allowed for an additional 1 hour labour. During this time the detection conditions surrounding fault code P were pursued to include: fuel pressure, intake and exhaust integrity, 4-Gas emissions and combustion efficiency based on O 2 signals.

All proved inconclusive! During the above tests it was noted that cranking time had increased before the engine would start accompanied with lumpy idle speed before stabilising. Could this be compression related as we seem to have exhausted all other possibilities?

At last, a breakthrough in the diagnosis and something conclusive to follow. I have to say at this point, this is the second time I have used the Waveform Library during real-life diagnosis to confirm valve timing errors and both times it has proved to be successful. Here we are looking at a small correlation error that would appear to be outside the detection of the PCM given no correlation codes have been recorded!

Could this error be responsible for our Map sensor and fuel trim codes? In order to qualify this valve timing error the rotation rulers were used to indicate degrees of crankshaft rotation between each engine position reference point missing teeth of the crankshaft sensor signal.

With the rotation rulers in position the time rulers can be used to indicate not only time, but degrees of rotation with reference to the position of the rotation rulers 0 - degrees.

Further analysis of the Camshaft timing error highlighted an alarming shift in the correlation during engine cranking see above. Here we can see a shift in the relationship between the Crankshaft and Camshaft by 1. With the confirmation of shifting valve timing, the pressure transducer was installed into each cylinder for an overview of the effects on peak compression where all were found to be normal.

However, an exhaust back pressure of 1. Could the exhaust back pressure be a result of shifting valve timing 1. Both have the potential to effect all cylinders equally and both could produce the symptoms described by the customer lack of power, fuel trim correction and cutting out.Fix the error 04B7 quickly and favourable with autoaid.

You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. So you should chech it on our car models.

The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.

If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.

Parts or components should not be replaced with reference to only a U DTC.

If one of these reasons for U code is occuring now you should check U repair processes. Now don't ask yourself; What should you do with U code? The solution is here :.The second one is probably as I don't have the air quality sensor but have the button as I've upgraded to a FL climate panel its a pre FL car. Any ideas about the first? Can't find the fault codes on the Ross Tech Wiki. The compressor works fine, but not sure how to determine the number of flaps?

Be interested in the loom and sensor. Are you saying it only works if I have one flap? Well its certainly the pre fl unit, the only thing I changed was the switch panel. Where does the sensor reside? Any new info about that first fault code? Everything seems to be running fine and i did some logging of the AC compressor and it runs as it should. I can post the full fault code list as soon as i get the codes from the another laptop I googled it at length and could find very little. But I have had no problems so am no longer worried.

I did read it might be to do with the newness of the panel and it wouldn't occur if the FL panel had a part with an A suffix. But I have never tested this. Also i can't code the unit. VCDS displays an error and nothing happens. So first two codes are because the unit is too new for my car. The third is for the missing air quality sensor and the last is because it is not coded.

I tried to apply and codes but it doesn't accept those. Here is my coding so perhaps try ? I had none of your troubles I am afraid - the comp ressor adaptation worked fine for me after about 3 seconds of holding the buttons.

I'll try the coding again today. I was wondering that would the version of VCDS be important here? If the panel is too new for my I could try to source a newer version of it and try with that May well do. Current vcds is If its a genuine cable its just a simple download. Coding worked with that code, so one fault code less on the system. I'll have to try the compressor adaptation again in the summer when the requirements with the weather are met for it to run. If id doesn's work then, i'll have to purchase an older version of the panel.

Some newer components have a challenge-response function. The component sends out a message saying 'Here I am - if all is well, answer me'. If it doesn't get a valid response it will either shut down completely or limit functionality. Your car doesn't know how to respond as the new panel isn't an option. Whilst I haven't seen anything called an option licence, this functionality will allow for it.

Components can also raise component protection codes if safety critical options have been disabled or to protect themselves. AFAIK, only a dealer can reset these codes.Each region we visited was different and each had its own charm and beauty.

When we returned to Canada we recommended Iceland as a place to visit, and to contact Nordic Visitor because they offer outstanding service. The information package was well put together. We really appreciated the map which highlighted the trip route, points of interest and daily accommodations.

Communication with him was very nice from very beginning till final e-mails before our arrival to Iceland. We would be very happy to have opportunity to use Nordic Visitors again in case of our travel to Scandinavia. The driving tour was perfect for us. We had the security of your expertise and guidance, but we had all the freedom we wanted since we were driving ourselves. We were a bit apprehensive about driving in Iceland, but it turned out to be very easy and enjoyable.

The scenery was awesome and the driving distances were very manageable.

I'm glad we added extra time in Reykjavik. I would have enjoyed even more time there. All of your materials were well prepared and fun to read. The Iceland Road Guide is spectacular. I am still reading it. Together with Alexandra at Nordic Visitor, we planned a 10-day trip around Iceland.

From the very first contact, Alexandra was extremely helpful and creative in responding to our wishes. The entire (interactive) planning process ran very smoothly. All the information sent to us (by regular mail and email) before the start of the trip was very informative.

From the moment we landed in Iceland, everything was again very well organized. The Road Atlas that the company provides is a great asset. Hotels and guesthouses were of high quality and everywhere we went, the food was great.

The pre-booked excursions were very well-organized too. In general, we noticed that Nordic Visitor has an excellent network of hotels and guesthouses, and of companies for local excursions (glacier hike, whale watching, where, by the way, we got a great show by one whale).

Thank you Alexandra and thank you Nordic Visitor. You are a great company to work with. Too bad Nordic Visitor has no control over the Icelandic weather. My husband and I traveled through Nordic Visitor for a full circle Iceland Activity Tour. We could not have asked for a better trip.

The wonderful reviews helped us decide to book with Nordic Visitor and I wanted to share the positives of our vacation planned through Nordic Visitor. My husband and I had never traveled out of the United States before and wanted a trip that was well planned by locals.

I feel that our tour allowed us to see much of the beautiful country. Iceland in general, is a very travel friendly country and I recommend a trip there to anyone who appreciates vast interesting landscapes, friendly people, and a whole lot more.
