I have an A2 - 1.2 tdi - 2001 ~odo:190k km - with climatronic and servo. My fuel consumption is 6.9L/100km Next things are new and modified in the last 1000km: -n75 valve -maf -timing belt (torsion value is now ~1+ but before this the consumption was around the same) -oil and filters -oil chain and gears -thermostat -water temperature sensor -new clutch and gearbox basic settings -new vacuum lines (vacuum drops only on brake pedal -> usually vacuum is around -0.75 bar) -egr blocked and not blocked -> the same result -Breaks seem fine - not stuck -tires have factory specified inflation ->2.5/2.9 bar I just did a graph for boost and maf. This part seems fine. The turbo actuator moves freely. Boost seems ok. Any other tips where to look? The car seems to work fine. After n75 change it seems to respond better but consumption is the same. They say I am an aggressive driver but I do not believe I am 3 liters aggressive:) . I live uphill so every time I commute home I drive uphill around 9km usually at maximum speed but the little one reaches maximum +110km/h.

Another example: You can load multiple files and see the graphs under each other:

Hello, I found this awesome vcds plotter for those interested: https://kiksu.net/vcds-graph/ You insert the vcds log directly. Press "insert log" and select the log from computer. The log below is for: Audi a2 - 1.2 any 2001. Tested for boost pressure (I just changed n75, maf and lots other) Example with one of my vcds logs -measuring blocks, egine, group 011,010,015: (if you press the "legend" you can eliminate what data to be on the graph or not)

This are the instructions for the above stickers

question for the experts: Any ideea if the oil sensor error generates a safe map for the car? The engine seems to work better....but it just might be placebo:)

IT WORKS....super I drilled 2 holes 5mm each at the specified measurements in photos (11.15mm from the side and ~16 - 22 mm from the side) - drilled from "outside to inside". Then I used a chainsaw file to enlarge the hole to spec... I did not want to use a big drilling bit because of the angle. No more stupid error....ieeeeei:D

It arrived in 2 weeks but it was cheaper. There is another ofer for 141eur +15eur transport in my case. Anyways there are tons of offers compared to the a2 version.

yes - the oil dip stick goes in that hole...:))...that's why it is a different number. - Frickler The number is in the first picture. Isn't the picture good enough? -janihani I hope this afternoon i have time to lift the car and swap the sensor.

It finally arrived It seems very easy to drill the hole. I will keep you posted after install. This is the r8 version. It was half the price from ebay - compared to the one specific for a2.

Yesterday I installed the front dampers mentioned here. front: I used kyb springs - bilstein were not in stock. rear: I used kyb excelg dampers and lesjofors springs. The rear feels a little bit softer than the front but it is fine. The front is 1.5 cm higher than the 18 year old original version but I believe that is close to original height. I am not afraid to go into potholes or enter a curve at higher speed - not anymore :). I can enter curves at the same speed as I do with my golf. Thanks for those who tested those before us. greetings from Transylvania.

Do you have notification here when the hood is opened? For me it works only for doors and trunk. (I need this information because the sensor seems to be related to the hood switch) german: Haben Sie hier eine Benachrichtigung, wenn die Haube geöffnet wird? Bei mir funktioniert es nur für Türen und Kofferraum. (Ich benötige diese Informationen, da der Sensor mit dem Haubenschalter in Beziehung zu stehen scheint.)

I ordered from here - I will keep you posted if it works or not: Ich habe hier bestellt - ich werde Sie auf dem Laufenden halten, ob es funktioniert oder nicht: https://www.ebay.com/itm/GENUINE-OEM-Oil-Level-Sensor-AUDI-R8-422-423-427-429-420907660/263561481454?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

Awesome answers. I did not notice that the hole is not all the way trough. I noticed only the entry point that seems to be in the right position. It seems that the hole is almost fully trough...I will test this and come back with an answer (after some more money come in:D). Thanks janihani for the photos. german: -google translate: Tolle Antworten. Ich habe nicht bemerkt, dass das Loch nicht ganz durch ist. Ich habe nur den Einstiegspunkt bemerkt, der an der richtigen Position zu sein scheint. Es scheint, dass das Loch fast vollständig durch ist ... Ich werde dies testen und mit einer Antwort zurückkommen (nachdem etwas mehr Geld eingegangen ist: D). Danke janihani für die Fotos

Aparently the audi r8 has a similar oil level sensor like the a2 1.2 tdi any. The r8 number: 420907660 The 1.2 oem no is: 045907660B The r8 version seems cheaper and more available than the a2 version. Usually it is around 40 -50 euros cheaper. Did anyone try this? (I cannot fix mine - the soldering did not do the trick) Thanks for the info on the forum. It is very useful. german - google translate: Anscheinend hat der audi r8 einen ähnlichen Ölstandsensor wie der a2 1.2. Die r8 Nummer: 420907660 Die 1.2 OEM-Nr. Ist: 045907660B Die r8-Version scheint billiger und verfügbarer zu sein als die a2-Version. Normalerweise ist es um die 40-50 Euro günstiger. Hat jemand das versucht? (Ich kann meine nicht reparieren - das Löten hat den Trick nicht getan) Danke für die Infos im Forum. Es ist sehr nützlich.
