It's happened to me twice and both times the reason was the N75 got bad.
The N75 thingy is located on the driver's side in the engine compartment and has three vacuum pipes attached to it along with electrical connector. And it has white cap.
To check if it really is the N75 fault you just...
Done. Today I changed the IQ value from 3.2mg/stroke to 5.2 mg/stroke. Went from 32768 to 32700 in the adaptation channel. As soon as I`m on empty tank I`ll fill up at Topia again. And then let`s see
Sam, I just sent you E-mail.
I didn`t write down all the numbers that appeared on the Vag-Com screen. I only wrote the explanation: "Quantity Adjuster Reached Upper Limit (N146)". Both times it was the same. And Vag-Com didn`t say it was intermittent. So I guessed it was solid. I keep my...
And definitely not me. I filled up my car with Bio-Diesel in Unionville the very first day Topia opened that station. I`d even prefer good Bio to Atlantic Irving`s diesel wich is the best diesel fuel available in Canada, imho. BUT... I`m not a millionaire.
What I`m thinking right now is if (!) Toronto_Vento and I caught some glycerin and the screen is partially clogged with it - in that case the pump behavior is understandable. In the morning when fuel and the pump is cold we get DTC, because Cold Start Valve value hits upper level. Then during...
Ok, I`ve made some measurements. Timing seems to be fine. In "Basic Settings" 9 block gives 131, 2 block gives 044 which is pretty much close to the optimum line in the manual. Just below it. Two years ago it was almost at the same position. Now group 4: Cold Start Valve value is 43.8% with...
Good point. I`ll take a look at my Basic Settings today. Btw, do you have any kind of procedure for changing that N146? Do I have to remove injection pump?
Now we`re getting somewhere. Let`s see... the first time that DTC appeared it was Sunday early morning, June 6. And I filled up my car with more than half the tank of Bio on Wednesday, June 2. From the same station you did. It`s rather interesting, isn`t it? So after I got DTC I immediately put...
Looks like some kind of rocket science
I`m asking because today I got those famous Quantity Adjuster Reached Upper Limit DTC again. And want to know what that N146 looks like. The last time I got that DTC a week ago I just changed my fuel filter and filled the new one with Kleen-Flow Cleaner...
