My VAG COM Log how bad is it?

[Cupra Ross]

The LCR block is different from the 180, was hoping to see actual vs expected Lambda factors. No matter. Assuming the obvious here but you have tried driving the car with the MAF sensor disconnected, right?

 

[Scorponok]

Yeah mate made no difference at all, I disconnect it again just incase but when I first started having the problems I tried that. The DV doesn't make a noise like it did like the air ain't getting that far round if you know what I mean. Would a leaky intercooler cause this much havoc?

 

[Cupra Ross]

Is the dump valve the standard plastic one or have you upgraded it? It sounds to me like you have a huge boost leak or the dump valve is stuck open.

 

[Scorponok]

I got a Forge 007 on there, previous owner had a blow off valve on there so I put the correct one and corrected hose. Yeah I'm thinking a serious boost leak or turbo
I have checked what I can and can only presume it's leaking from intercooler (if that's possible) guess I have to see what happens at the smoke test. Cheers for your help mate I post what happens Thursday.

Check the working of the Forge by pressing in the piston and holding your finger on the vacuum nipple. It should stay in place.

 

[Scorponok]

Checked DV like you said holds pressure until I let go of the top so all good. New development now as it starts to boost then dies now im getting a low sound like a deep sound of an exhaust then tries to boost??? This car is beginning to test my patience grrrt

 

[Cupra Ross]

How is the spring in the dump valve?

 

[ibizacupra]

Ok cheers mate, I've booked the car for a smoke test for Thursday. I checked all pipes I think the major ones all seemed ok. I found a split pipe under manifold which I replaced which didn't really have a major effect. It sounds like air is escaping or being sucked in where it shouldn't. Does feel like car is holding back so your probably right about the throttle butterfly is holding back hence the real massive lack in power. The rod seemed fine it was tough to pull but not sure about wastegate. Thanks so much for taking the time to check my logs I might pop and double check some more hoses but I got a funny feeling the sound is coming from intercooler on the drivers side. There's no oil around there which I would of expected if it was, be nice once it's storted I haven't been able to enjoy driving the car really. Thanks again to you and everyone for your input. I keep you all posted

to confirm throttle 003 block, boost actual 118
its not like you have Any boost tho, not even actuator pressure which would be 1300mb actual (ish)

The numbers are the same all the way down to 16 on time stamp

same blocks.

same blocks.

Different to mine Bill, last time I logged Block 031 it gave Lambda Factors rather than voltages:

I won't second guess you because you know far more about this stuff than I do. I can understand using the Lambda Factors to confirm adequate fuel supply, but sensor voltages mean nothing to me.

 

[ibizacupra]

only narrow band ecus give voltages on 031
all wideband are requested and actual lambda's

you post lambda values here not voltages

incorrect label file on your vcds perhaps

Ok thought I let you know what's happened.
Was due for a smoke test but garage rang to say there machine wasn't working so ok fair enough.
I decided to check things over again, well in one thread I made I said the the BMA CDA filter had a gap round the maf sensor it had 2 nuts they used as spacers. Well I removed spacers and sat it flush. I did that the day I was looking for the boost leak I had which back then was a slight one. Anyway today I thought I would put spacers back just incase and well BINGO got all my power back!!! I must of fixed something else as there is no leak either! I reckon the filter must be caked in dust or something that it can only draw air thru that gap? Going to buy a replacement filter ASAP. Thank you so much guys for the patience and help to try and sort this for me. Now to sort the other problems out but least it feels like a Cupra R

 

[ibizacupra]

BMC CDA - Bin it. terrible restrictive filter.

This +1

Yeah going to bin it, really didn't expect it to be that!
