So I tried another actuator and the behaviour is exactly the same. So my actuator and modulator are ok. I took another measurement while driving and at full throttle I got 230kpa on my nanocom (MAP) and 260kpa on the gauge I connected before the actuator (see pic). Is this difference within...

Issue just found! Wear on the cables from MAF/MAP to the ECU. Found it by coincidence. Hopefully that is the end of it.

Update The problem was never found. The next day the car worked as normal and for the last 5 days I have been using it with no issues. I did check for earth issues, wear on the cables from the pedal to the ecu but couldn't find anything wrong. I guess I'll never find out what happened. One...

After you enter the EKA code you need to wait 5 minutes (you will hear another beep) and after that you open the door and start the car. Did you do that?

It's beer time...

Tried another pedal and then issue persists....

Another weird thing is that if I clear the fault it doesn't appear if I select Reverse. As soon as I engage any forward gear the engine light comes on and pedal dies.

Problem solved itself for a while. It reappeared after a short drive but now only acceleration way 3 is not responding. And the fault related to the pedal appears in tandem with ambiant pressure circuit. Now I have: 02-07 driver demand supply problem 02-08 ambiant pressure circuit 21-06 problem...

So I was trying to solve a turbo pressure issue that persists for some time now and ended up with a bunch of new issues and no drive! While trying a new wastegate actuator, removing the inlet hoses to check for delamination etc I ended with engine light on and no drive. I connected my Nanocom...

Overboost? Wastegate modulator playing up?

I will find a non faulty actuator from a friend with a td5 to try out and report back. My Nanocom is a very old mk1 version with no sd card. It needs cables and cds that I don't have in order to connect to a laptop. Maybe I can find a newer model from a friend.

AAP at this altitude is always 97-99 I was thinking maybe the ECU sees a different (slightly higher) instantaneous MAP than what I see on my Nanocom when getting close to 142 because of lag in transmitting the data. I can't record data on my Nanocom so is what I see on the screen when driving...

I tried to, it was shooting to 230+ and kangarooed. The strange thing is that no overboost fault was recorded on the ECU like it did a couple of days ago.

When you say valve do you mean the wastegate actuator?

So I went for a quick spin having the hose going to the actuator blocked and the thing kangarooed as soon as I put my foot down doing 30-40mph. No fault was recorded to the ecu.

I will try with a clamped hose to see if it overboosts and report back. If there is a restriction between turbo and MAP then it will still not overboost (I'm guessing). Reusable K&N filter, cleaned recently. 10p, no EGR, no CAT.

They aren't the original ones. They were replaced with silicone ones by the previous owner.

Same diagnose with the new info? Modulator was replaced very recentry and I checked the actuator using a bicycle pump and it responded as expected. I checked for split hoses and can't see anything suspicious.

After my previous posts I was using the car without paying attention to the numbers (I had other issues to deal with anyway). Yesterday when going up a hill in the motorway it dropped to 3rd with no reason and at that point I noticed a lack of power. When I checked using the nanocom I found out...

When the actuator is disconnected the wastegate swings in both directions with no resistance
