Hi, I have a Ibiza Mk5 Cupra 1.4 TSi and have a few problems of which I cannot seem to find a real solution to anywhere on the internet. I have a 2010 (60 plate) Cupra with Stage 2 APR remap, Milltek turbo back decat exhaust and itg induction, uprated spark plugs (ones recommended by REVO and on here "BKR7 or something). Its currently on 56k miles and going to go for new cambelt, waterpump, engine and gearbox oil, filters etc at the end of Feb.
Problem 1:
There is a juddering / hesitation at around 6800-7200ish RPM when at full throttle mainly in 4th gear (but a little in 3rd too if going up hill). This used to start around 5500-6000 rpm but new shorter spark plugs and coil packs solved that bit, but its still there and causes the engine light to flash about 5 times and then goes into limp mode. However, if I turn the car off and back on its perfectly fine as if nothing happened. There is a bit on the internet about this with misfires etc so just change gear manually at about 6500rpm max and its fine, but would love to know how to solve it.
I have put the newest revised valve (believe it to be the N75) that goes to the left of the turbo just above the air intake on the turbo. I have also bought a new N249 valve (hasn't arrived yet) as I got the following code:
2998 - Boost Pressure Control Valve (N249)
P2261 00 [109] - Mechanical Malfunction

Problem 2:
Sometimes (can happen 100 times in one day and not happen again for a week) when I lift off the throttle in 5th gear or above it judders when the pedal is at around 10% down. This can be quite violent sometimes, as if the brakes have been pressed sharply for a split second. As it doesn't happen all the time I'm ruling out the pedal itself as surely it would happen all the time in every gear if it was faulty.
Problem 3:
I have VCDS and have the following code keep coming up with the gearbox:
006015 - Hydraulic Pump Motor
P177F - 000 - Insufficient Voltage - Intermittent
Freeze Frame:
Fault Status: 00100000
Fault Priority: 0
Fault Frequency: 4
Reset counter: 10
Mileage: 81493 km
Time Indication: 0
Date: 2050.14.11
Time: 21:08:48
This makes more or less no sense to me and I have searched and searched for answers and cannot find one on how to solve it. My guess if that there is either a loose connection somewhere or a faulty sensor.
Problem 4:
Amazingly this is probably the most annoying of them all. My boot light is flickering and comes on and goes off whenever it wants to (luckily not when the car is off so wont drain the battery etc). I've tried different bulbs and does the same, sometimes works fine and other times doesn't work for about a minute and then comes on for a few secs then back off. When I open the boot the boot open warning sign comes on the dash even if the boot light itself doesn't, so I think I can rule out the sensor/switch. Its just the boot light that does it, I understand they're on the same circuit as the interior lights which are perfectly fine.
Also according to VCDS but the hazard light switch is apparently shorted to ground. However it works 100% fine, but didn't know if the 2 were connected and maybe a short was causing it.
Sorry for the essay lol, any help will be greatly appreciated. Thank you for your time for reading.
