I had the above logged at the weekend there. Can see from column 3 on block 001 that the ECU is trying to add fuel to the mix but it can't. The guy that did the logs for me (reputable tuner around these parts) reckons this is likely to be fuel pump, or less likely the FPR (fuel filter was changed about 3000 miles ago so not that).

Just posting really to update this thread. I'm going to change the fuel pump and log again to see if that fixes it.

 

[leon cupra r]

Sorry I'm confused by this - you mean column 4, lambda values right? What are they supposed to be? they seem to be fluctuating a bit, I'm not sure what to expect or what shows that more fuel is being requested or what shows it can't be delivered?

No disrespect to the guy, but if he is reputable I can't see him logging on three blocks as it slows the sample rate down (I learned this the hard way myself when I first got Vagcom) and also not mentioning anything about your high CFs on cylinders 3+4... I presume the values on block 20 are still measured on the same scale, think my version says CF whereas this says °KW - if so they are starting to creep up a little high...

I'd be happy to do a comparison log but need to find the time, always seem to be busy at the moment!

and the latest update from my end is finding a bloody nail in my back tyre, surprisingly enough, too close to tyre wall to replace, meaning two new tyres not a happy bunny!! lol

 

[8bit]

Sorry, yes - the first column is the timestamp, if you look at the sensors logged in block 001 then the lambda figure is the third column, sorry for the confusion

I didn't give a very clear description of what's going on there. That lambda control value is the ECU trying to correct fuelling because it's detecting through the narrowband and wideband probes in the exhaust that it's not getting enough in the mixture. This tells us that the ECU is working right, it's trying to correct the lean condition but it's unable to do so, most likely due to a fuel supply flow or pressure issue. This could be an old, tired fuel filter, in my case not though because I had it changed not long ago and it was running lean before and after.

The guy did spot and point out the knock detection on cylinders 3 and 4, he reckons this is likely to be due to the lean running. We just did all three blocks at once the first time and left it at that because it was obvious from the above that something's going on with the fuelling so it meant only having to do one run rather than two or three.

I've been for a run in a mk1 LCR that this guy custom mapped from scratch and it's an animal, no doubt in my mind that this guy knows his onions. He's mapped a number of other VAG cars belonging to members of a local forum and a number of folks have recommended him very highly.

Sorry to hear about your tyre nightmare! There's always something with cars eh. I'm going to have to get 4-wheel alignment done now after getting my front ARB fitted. At least mine sailed through the MOT last week with not even a single advisory, bit of good luck for a change!

and what is block 032 sat at currently?

 

[8bit]

Not sure, got my replacement VAGCOM cable through so I'll see if I can check it tonight. Does this have to be done as a power run or just read with the engine off at standstill?

 

[8bit]

and what is block 032 sat at currently?

Bill, managed to check my block 032 tonight, see below:

Group A:	032	
	Lambda	Lambda
TIME		
STAMP	%	%
0	0.2	-8.6
0.4	0.2	-8.6
0.8	0.2	-8.6
1.29	0.2	-8.6
1.69	0.2	-8.6
2.11	0.2	-8.6
2.61	0.2	-8.6
3.01	0.2	-8.6
3.41	0.2	-8.6
3.82	0.2	-8.6
4.32	0.2	-8.6

I guess that suggests that the ECU thinks the car's running rich when under load so it's leaning it out, but if I read things right then the logs of block 001 further up this page show that the ECU is trying to add a little fuel right across the range.

Any ideas? My car is also showing codes relating to the post-cat lambda just now, could this be my issue? See below for codes:

2 Faults Found:
16522 - Oxygen (Lambda) Sensor B1 S2: Signal too High
            P0138 - 35-10 - - - Intermittent
17584 - Bank1: O2S (Lambda) Correction Behind Catalyst: Control Limit Reached
            P1176 - 35-00 - -
Readiness: 0000 0000

 

[ibizacupra]

no leaks in your manifold/turbo/downpipe before the 1st lambda?
overfueling is making the cat unhappy...

wonder if your fpr is partially blocked?
Seen this twice on BAM engined S3's so far.. fuel feed line falling apart internally. remedy replace that section of rubber fuel hose

 

[8bit]

Many thanks for helping as always, Bill. No idea about leaky mani's or exhaust, the car passed MOT and emissions test 2 weeks ago so I'd have thought that would show up there, right?

I'll check the FPR, is that a case of popping the fuel pump fuse out, starting the car til it stalls then unclipping and inspecting?

Finally, if it is that section of hose, is it worth replacing it with something better than rubber? Where does the other end of the hose go, is it the canister thing that everyone asks "what's that ticking sound" about when they first get their car (me included)?

OK so that hasnt come out as well as it should - have just formatted PC so no office - pasted straight out of the almighty word pad! anyway, seeing as the forum wont let me delete it and come back later, I may as well leave it like this for now, you can still get the gist...

My block 1 lambda value seems to be doing the opposite of yours niall? The top run was only in 2nd gear (didnt have time to go to longer road to log on) but managed to get a cheeky run in third below:

which has a few more samples, but still showing the same thing...

Bill do you have any ideas? any other blocks that may be worth logging?

Looks to me like yours is pulling back the fuelling a little bit mate, like it's thinking it's running slightly too rich.
